Balanced ionic equation for sodium thiosulpate reacting with sulphuric acid

Answer:B is the right answer

Explanation:

Answer:energy is emitted as electromagnetic radiy

Explanation:

Based on the balanced equation, if we have 0.08 moles of Iron (Fe), we can conclude that 0.08 moles of Hydrogen (H₂) will be formed as well.

First we need to balance the chemical equation for the reaction involving Iron (Fe) and Hydrogen (H).

The reaction will be between Fe and HCl (hydrochloric acid) to produce hydrogen gas (H₂) and iron chloride (FeCl₂):

Fe + 2HCl → FeCl₂ + H₂

From the balanced equation, we can see that for every 1 mole of Fe reacted, 1 mole of H₂ is formed. Therefore, if we have 0.08 moles of Fe, we can conclude that 0.08 moles of H₂ will be formed as well.

The acid dissociation constant (Ka) value for C₆H₅NH₃ is 5.68 × 10⁻⁶, and the base dissociation constant (Kb) value for C₆H₅NH₂ is approximately 4.35 × 10⁻¹².

To calculate the acid dissociation constant (Ka) for the weak acid C₆H₅NH₃, we can use the equilibrium expression for the acid dissociation reaction:

C₆H₅NH₃ + H₂O ⇌ C₆H₅NH₂ + H₃O⁺

The equilibrium constant expression is given by:

Ka = ([C₆H₅NH₂] × [H₃O⁺]) / [C₆H₅NH₃]

Given the equilibrium concentrations:

[C₆H₅NH₃] = 0.233 M

[C₆H₅NH₂] = 2.3 × 10⁻³ M

[H₃O⁺] = 2.3 × 10⁻³ M

Substituting the values into equilibrium constant expression:

Ka = (2.3 × 10⁻³ M × 2.3 × 10⁻³ M) / 0.233 M

Ka = 5.68 × 10⁻⁶

Therefore, the Ka value for C₆H₅NH₃ is 5.68 × 10⁻⁶.

To calculate the base dissociation constant (Kb) for the weak base C₆H₅NH₂, we can use the equilibrium expression for the base dissociation reaction:

C₆H₅NH₂ + H₂O ⇌ C₆H₅NH₃⁺ + OH⁻

The equilibrium constant expression is given by:

Kb = ([C₆H₅NH₃⁺] × [OH⁻]) / [C₆H₅NH₂]

Since we know the concentrations of C₆H₅NH₂ and H₃O⁺, we can use the relationship that [H₃O⁺] × [OH⁻] = 1.0 x 10⁻¹⁴ (at 25°C).

Given the equilibrium concentrations;

[C₆H₅NH₂] = 2.3 × 10⁻³ M

[H₃O⁺] = 2.3 × 10⁻³ M

We can calculate the concentration of OH⁻ using the relationship;

[OH⁻] = 1.0 x 10⁻¹⁴ / [H₃O⁺]

[OH⁻] = 1.0 x 10⁻¹⁴ / (2.3 × 10⁻³) M

[OH⁻] ≈ 4.35 × 10⁻¹² M

Substituting these values into the equilibrium constant expression;

Kb = (2.3 × 10⁻³ M × 4.35 × 10⁻¹² M) / (2.3 × 10⁻³ M)

Kb ≈ 4.35 × 10⁻¹²

Therefore, the Kb value for C₆H₅NH₂ is approximately 4.35 × 10⁻¹².

Ag+ (aq) + Cl- (aq) --> AgCl (s)

Explanation:

The cloth was painted with organic dye approximately 2,300 years ago ( rounded to two significant figures ).

To determine when the cloth was painted with organic dye, we can use the half-life of carbon-14 and the given information that 71% of the carbon-14 remains. The half-life of carbon-14 is 5,730 years.

Step 1: Calculate the decay factor.
Decay factor = remaining percentage / 100
Decay factor = 71% / 100 = 0.71

Step 2: Use the decay formula.
N(t) = N0 * (1/2)^(t / half-life)
0.71 = (1/2)^(t / 5730)

Step 3: Solve for t (time in years).
t / 5730 = log(0.71) / log(1/2)
t = 5730 * (log(0.71) / log(1/2))
t ≈ 2349.27 years

Expressing the answer to two significant figures, the cloth was painted approximately 2,300 years ago.

Answer:

Water is a remarkable substance, and its unique properties are largely due to the presence of polar covalent bonds and hydrogen bonds in its structure. These characteristics play a crucial role in the physical and chemical properties of water, making it essential for life as we know it.

Explanation:

The polar covalent bonds in water arise from the unequal sharing of electrons between oxygen and hydrogen atoms. This results in the oxygen atom having a partial negative charge (δ-) and the hydrogen atoms having partial positive charges (δ+). These charges create polarity within the water molecule, leading to the formation of hydrogen bonds.

Hydrogen bonds occur when the partially positive hydrogen atom of one water molecule is attracted to the partially negative oxygen atom of another water molecule. These hydrogen bonds are relatively weak individually, but when present in large numbers, they contribute to the cohesion, surface tension, and high boiling point of water.

The importance of these bonds is manifold. The cohesion between water molecules due to hydrogen bonding enables water to form droplets, have a high surface tension, and flow freely, facilitating transport within organisms and in the environment. Additionally, hydrogen bonding leads to the high specific heat capacity and heat of vaporization of water, making it an effective regulator of temperature in living organisms and ensuring stable environmental conditions.

Furthermore, hydrogen bonds play a crucial role in the unique properties of water as a solvent. The polar nature of water allows it to dissolve a wide range of substances, including ionic compounds and polar molecules, facilitating various biological processes such as nutrient transport and chemical reactions in cells.

In step with Bohr's model of the hydrogen atom, how is hydrogen's emission spectrum produced while an electron falls from a higher to a lower orbit (power degree) electricity is given off (orbit). The one-of-a-kind orbits produce constant traces inside the emission spectrum of hydrogen.

The electron in a hydrogen atom absorbs electricity and gets excited. The electron jumps from a decreased energy stage to a higher energy degree and when it comes returned to its unique country, it offers out electricity which bureaucracy a hydrogen spectrum.

The light emitted by means of hydrogen atoms is red because, of its four function strains, the maximum severe line in its spectrum is in the pink part of the seen spectrum at 656 nm.

the micro structure that would be formed by polypropylene would be a semi-crystalline structure. This is a result of how polymer chains are organized and how the substance behaves during cooling and solidification. Long chains of propylene monomer units make up polypropylene.

These chains are generated during the polymerization process and become intertwined. The molten polypropylene goes through a process known as crystallization as it cools down. The polymer chains arrange themselves into crystalline and amorphous regions in the semi-crystalline

micro structure of polypropylene. In contrast to amorphous sections, which are more randomly structured, crystalline regions are made up of tightly packed, highly ordered polymer chains. The level of crystallinity can change according on the processing circumstances, cooling rate, and molecular weight.

In polypropylene, the creation of the semi-crystalline micro structure gives the substance good mechanical qualities like stiffness, strength, and impact resistance. The amorphous portions offer flexibility and impact resistance, while the crystalline regions contribute to the material's strength.

Explanation:

True. The gravitational force of the moon has a stronger effect on tides than the gravitational force of the sun, even though the sun is much larger and more massive than the moon.

This is because the moon is much closer to the Earth than the sun, and its gravitational pull is therefore stronger. The sun's influence on tides is about half that of the moon, and it mainly affects the tides during spring and neap tides. The combined gravitational force of the sun and moon creates the largest tides, known as spring tides, while the smallest tides, known as neap tides, occur during the first and third quarter phases of the moon. True, although the sun does influence tides, its effect is considerably less than the effect of the moon. The sun's gravitational pull on Earth is weaker due to its distance, causing its tidal impact to be only about 46% that of the moon. The moon's closer proximity to Earth results in a stronger gravitational force, making it the primary driver of tidal patterns. Hence, the lunar gravitational pull has a more significant impact on tides than the solar gravitational pull.

Answer:

Rate cup 1: 36.00 tsp/h.

Rate cup 2: 59.50 tsp/h.

Rate cup 3: 70.13 tsp/h.

Explanation:

Based on the given example, the units must be in tsp/hour. To do this we just have to divide tsp by seconds and then convert it to hours remembering that 1 hour equals 3600 seconds.

Let's calculate each case:

- Cup 1: 1 tsp, 1 minute 40 seconds. Remember that 1 minute equals 60 seconds, so 1 minute and 40 seconds equals 100 seconds. The calculation of the rate will look like this:

The rate of cup 1 is 36.00 tsp/h.

- Cup 2: 2 tsp, 2 minutes 1 second. As we saw before 1 minute equals 60 seconds, so 2 minutes equals 120 seconds. 2 minutes and 1 second equals 121 seconds. The rate of cup 2 will be calculated as:

The rate of cup 2 is 59.50 tsp/h.

- Cup 3: 3 tsp, 2 minutes 34 seconds. 2 minutes are the same that 120 seconds, so 2 minutes 34 seconds equals 154 seconds. The rate of cup 3 is calculated as follows:

The rate of cup 3 is 70.13 tsp/h.

Explanation:

Particles in both liquids and gases (collectively called fluids) move randomly. This is called Brownian motion. They do this because they are bombarded by the other moving particles in the fluid. Larger particles can be moved by light, fast-moving molecules.

Brownian motion is named after the botanist Robert Brown, who first observed this in 1827. He used a microscope to look at pollen grains moving randomly in water. At this point, he could not explain why this occurred.

In a cube full of small fast-moving particles, two much larger particles appear to move at random as a result of collisions with the smaller particles.

Brownian motion

But in 1905, physicist Albert Einstein explained that the pollen grains were being moved by individual water molecules. This confirmed that atoms and molecules did exist, and provided evidence for particle theory.

To solve this we must be knowing each and every concept related to speed  and its calculations. Therefore, the correct option is option C.

Speed may be defined as the distance traveled by an item in the amount of time it requires to travel that distance. In other words, it measures how rapidly an item travels but does not provide direction.

The Scientific unit system is most typically used to express speed. Speed is determined in metres per second, or m/s, since distance is recorded in metres while time is recorded in seconds.

Mathematically,  

speed= distance/ time

distance= 10 miles
