In sulfur trioxide there are 32.06 grams of sulfur are combined with 48 grams of oxygen.

The ratio of oxygen which reacts with 32.06 gram of sulfur is 32: 48 .

This ratio is equal to 2 : 3.

This is in accordance with law of multiple proportion because , the ratio of mass of oxygen which reacts with constant mass of sulfur is integral ratio . Hence they are in accordance with law of multiple proportions.

Answer:

sulfur and oxygen can react to form both sulfur dioxide and sulfur trioxide in sulfur dioxide there are 32.06 grams of sulfur and 32 grams of oxygen in sulfur dioxide there are 32.06 grams of sulfur are combined with 48 grams of oxygen

a. what is the ratio of the weights of oxygen that combine with 32.06 g of sulfur?

b. How do these data illustrate the law of multiple proportions? ​

Explanation:

In sulfur dioxide (\(SO_2\))

32.06 g of sulfur reacts with 32.0 g of oxygen.

In sulfur trioxide (\((SO_3)\) 32.0 g of sulfur reacts with 48.0 g of oxygen.

So, both th ecom[pounds are made from sulfur and oxygen,

But the amount of oxygen reacts with fixed amount of sulfur that is 32.06 g and it is in proportions that is:

32.0 g : 48.0 g

=2:3.

Hence, the ratio of oxygen combines with sulfur is in the ratio of 2:3.

b.

This data illustrates the law of multiple proportions.

Because the oxygen which is combining with fixed amount of sulfur is in proportions.

2. Mass of the red ball is 3.75 kg.

Explanation:

The following data were obtained from the question:

For the blue ball:

Force (F) = 15 N

Acceleration (a) = 3 m/s²

Mass (m) =.?

Force the red ball:

Force (F) = the same with that of the blue ball = 15 N

Acceleration (a) = 4 m/s²

Mass (m) =.?

1. Determination of the mass of the blue ball.

Force (F) = 15 N

Acceleration (a) = 3 m/s²

Mass (m) =.?

Force (F) = mass (m) × acceleration (a)

F = ma

15 = m × 3

Divide both side by 3

m = 15/3

m = 5 kg

Therefore, the mass of the blue ball is 5 kg

2. Determination of the mass of the red ball.

Force (F) = 15 N

Acceleration (a) = 4 m/s²

Mass (m) =.?

Force (F) = mass (m) × acceleration (a)

F = ma

15 = m × 4

Divide both side by 4

m = 15/4

m = 3.75 kg

Therefore, the mass of the blue ball is 3.75 kg

Vm will be close the Eion which has the highest conductance at the point in the AP.

Vm, the membrane potential of a neuron, will be closest to the equilibrium potential (Eion) of the ion with the highest conductance at that point in the action potential.

Conductance is a measure of how easily ions can move across the membrane, and the ion with the highest conductance at a given point in the action potential will have the greatest influence on the membrane potential.

At rest, the membrane potential is close to the equilibrium potential of potassium (EK) because the resting conductance of potassium is high. During depolarization, the conductance of sodium (ENa) increases, and the membrane potential approaches the equilibrium potential of sodium.

During repolarization and hyperpolarization, the conductance of potassium increases again, and the membrane potential returns to EK.

P²= 1.25- atm

V²=?

T²=345K

P¹=0.75-atm

V¹=120

T¹=295K

So V²= (0.75 x120/295)x(345/1.25)

Volume of the gas V²= 84.20- ml

Answer:

Solution given:

at first

volume\(V_{1}=120.0ml\)

pressure \(P_{1}=0.75atm\)

temperature \(T_{1}=22+273=295°K\)

after increasing temperature and pressure

volume\(V_{2}=xml\)

pressure \(P_{2}=1.25atm\)

temperature \(T_{2}=70+273=343°K\)

now

\(\frac{P_{1}V_{1}}{T_{1}}=\frac{P_{2}V_{2}}{T_{2}}\)

substituting value

\(\frac{0.75*120}{295}=\frac{1.25*x}{343}\)

0.305=5x/1372

At the atomic level, the main factor that causes fudge topping to pour faster when heated is the increase in the average kinetic energy of its constituent particles.

When fudge topping is heated, the thermal energy is transferred to the molecules and atoms within the topping. As the temperature rises, the average kinetic energy of the particles increases. This increase in kinetic energy leads to greater molecular motion and faster molecular interactions within the fudge topping.

The increase in molecular motion and interactions results in a reduction in the viscosity of the fudge topping. Viscosity refers to the resistance of a substance to flow. As the temperature increases and the particles move more rapidly, the intermolecular forces holding the fudge topping together weaken, allowing it to flow more easily.

Hydroxide

Explanation:

In chemistry, a conjugate base is the species that remains after an acid has donated a proton (H+) to a base. Water (H2O) can act as an acid and donate a proton to a base, such as the hydroxide ion (OH-), according to the following equation: H2O + OH- → H3O+ In this reaction, water donates a proton (H+) to the hydroxide ion (OH-) to form the hydronium ion (H3O+), which is the conjugate acid of water. The hydroxide ion (OH-) is left behind and can be considered as the conjugate base of water.Therefore, the hydroxide ion is the conjugate base of water because it is formed when water acts as an acid and donates a proton to a base

The conjugate base of water is "hydroxide".

In water, the hydrogen ions (H+) can dissociate from the water molecule, leaving behind a hydroxide ion (OH-) as the conjugate base. This can be represented by the following chemical equation:

H2O + H+ ↔ H3O+

In this equation, H2O is the water molecule, H+ is the hydrogen ion, and H3O+ is the hydronium ion, which is the conjugate acid of water. The hydroxide ion (OH-) is the conjugate base of water.

Therefore, the correct answer is "hydroxide".

Glycinate donates an electron pair so it is a bidentate ligand.

The molecular formula is C₂H₄NO₂⁻. The octahedral complex is formed between glycinate molecules and cobalt(III) and the stoichiometry of the complex is [Co(gly)₃]. The reaction is as follows;

Co₃⁺(aq) + 3C₂H₄NO₂⁻ ⇒ [Co(C₂H₄NO₂⁻](aq)

A cobalt complex is formed when 3 glycinate ions equivalents react with one Co₃⁺ ion equivalent so, it is necessary to keep the glycinate ions concentration greater than the cobalt(III) ions at least three times more.

So, taking the concentration 4 times greater can facilitate the reaction.

The coefficient of oxygen gas after balancing the equation is 3.

To balance the given equation, we need to find the correct coefficients for the reactants and products involved. The equation is:
___P(s) + ___O2(g) → ___P₂O₃(s)

First, let's balance the phosphorus (P) atoms:
2P(s) + ___O2(g) → 1P₂O₃(s)

Now, let's balance the oxygen (O) atoms:
2P(s) + 3/2O₂(g) → 1P₂O₃(s)

However, having a fraction (3/2) as a coefficient is not ideal, so we can multiply the entire equation by 2 to get whole number coefficients:
4P(s) + 3O₂(g) → 2P₂O₃(s)

Thus, the balanced equation is:
4P(s) + 3O₂(g) → 2P₂O₃(s)

Mass is the most basic property of matter and it is one of the fundamental quantities. Mass is defined as the amount of matter present in a body. The SI unit of mass is the kilogram (kg). The formula of mass can be written as:

Mass = Density × Volume

The mass of a body is constant; it doesn’t change at any time. Only in certain extreme cases when a huge amount of energy is given or taken from a body, the mass may be impacted. For example, in a nuclear reaction, a tiny amount of matter is converted into a huge amount of energy, this reduces the mass of the substance.

There are various units for calculating mass, like, kilograms, grams, lbs, pounds, etc., but the SI unit of mass is "kilograms" or kg. Every unit of mass can be converted to other units by using a proper conversion formula without affecting the meaning and essence of the quantity to be measured.

If the balloon is closed, then yes, both volume and pressure will increase when the gas inside is heated.

What is pressure?

Pressure is the force applied perpendicular to the surface of an object per unit area over which that force is distributed.

Various units are used to express pressure. Some of these are units of force divided by units of area. For example, the SI unit of pressure, Pascal (Pa), is 1 Newton per square meter (N/m2). Similarly, pounds force per square inch (psi, symbol lbf/in2) is the traditional unit of pressure in imperial and US systems. Pressure can also be expressed as standard atmospheric pressure. Atmospheric pressure (atm) is equal to this pressure and torr is defined as 1/760 of this. Manometric units such as centimeters of water, millimeters of mercury, and inches of mercury are used to express pressure as the height of a particular liquid column within a manometer.
