917Kg/m³ is the density of 50,000 m³ iceberg of mass of 45,850,000kg. Grams per cubic centimeter are a typical unit of measurement for density.

Density is the mass of a specific material per unit volume. d = M/V, in which d is density, M is weight, and V is volume, is the formula for density. Grams per cubic centimeter are a typical unit of measurement for density. For instance, whereas Earth has a density of 5.51 grams per square centimeter, water has a density of 1 gram per cubic centimeter.

Another way to state density is in kilograms per cubic meter. For instance, air weighs 1.2 pounds per cubic metre. In textbooks and manuals, the densities of typical solids, liquids, as well as gases are stated.

density= mass/ volume

         = 45,850,000 /50,000

         = 917Kg/m³

Therefore, 917Kg/m³ is the density of 50,000 m³ iceberg of mass of 45,850,000kg.

Answer:

165.48 amu

Explanation:

First, you need to find the last percentage.

100% = 60.44% + 13.55% + x

100% = 73.99% + x

x = 26.01%

Now, multiply each mass by the respective percentage.

164.08 × 0.6044 = 99.17

165.11 × 0.1355 = 22.37

168.92 × 0.2601 = 43.94

Lastly, add the products together to find the average atomic mass.

99.17 + 22.37 + 43.94 = 165.48

H will have the longest wavelength emission line for the transition between the n initial = 2 and n final = 1 levels.

A movement (or leap) of an electron from one energy level to another within an atom or artificial atom is referred to as an atomic electron transition. It seems discontinuous because the electron "jumps" from one quantized energy level to another in a matter of nanoseconds or less.

Electronic transitions occur in atoms and molecules as a result of electromagnetic radiation absorption or emission (typically UV or visible). Planck's equation, E = h, relates the energy change associated with a transition to the frequency of an electromagnetic wave. Transitions between these permitted orbits occur in photon absorption or emission. A photon is released when an electron transitions from a higher-energy orbit to a more stable orbit.

Answer:

To determine the change in mass of A over the given time period, we need to find the difference between the initial mass of A and the final mass of A.

From the given table, we can see that the initial mass of A at t = 0 (start time) is 12.4 g and the final mass of A at t = 60 minutes (end time) is 6.2 g.

Therefore, the change in mass of A over 60 minutes is:

Final mass of A - Initial mass of A

= 6.2 g - 12.4 g

= -6.2 g

The negative sign indicates that the mass of A decreased over time, which means that A underwent some kind of reaction or process that caused it to lose mass.

The change in mass of A over 60 minutes is -6.2 grams.

To determine the change in mass of A over 60 minutes, we need to compare the initial mass to the final mass.

From the given information, we can see that the mass of A decreases over time.

Let's calculate the change in mass.

Initial Mass of A: 12.4 g

Final Mass of A: 6.2 g

Change in Mass of A = Final Mass of A - Initial Mass of A

= 6.2 g - 12.4 g

= -6.2 g

The decomposition of aspirin (acetylsalicylic acid, \(C_{9} H_{8} O_{4}\)) can occur through the hydrolysis reaction, resulting in the formation of acetic acid (\(CH_{3} COOH\)) and salicylic acid (\(C_{7} H_{6}O_{3}\)). To determine the moles of each product formed, we need to consider the balanced chemical equation for the reaction:

\(C_{9} H_{8} O_{4} = > C_{7} H_{6}O_{3} +CH_{3} COOH\)

From the equation, we can see that for every 1 mole of aspirin, 1 mole of salicylic acid and 1 mole of acetic acid are produced.

Therefore, the moles of salicylic acid and acetic acid formed will be equal to the number of moles of aspirin that decomposes. If we know the amount of aspirin in moles, we can directly calculate the moles of each product based on stoichiometry.

Over-tilling and Over farming are the two processes that can harm the fertility of the soil.

Over-tilling refers to the exceeding levels of tilling and levelling the soil which adversely affects the quality of the soil. This is because tillage fractures the soil, it disrupts soil structure, accelerating surface runoff and soil erosion. Tilling of soil also reduces crop residue, which help cushion the force of pounding raindrops.

Without crop residue, soil particles become more easily dislodged, being moved or 'splashed' away. The splashed particles clog soil pores, effectively sealing off the soil's surface, resulting in poor water infiltration and hence subsequently affects the soil fertility.

Similarly, the main effect of over-farming is soil depletion. When crops are grown in the same place year after year, the soil becomes depleted of the nutrients that the plants need to grow. This can lead to lower yields and poorer quality crops. In extreme cases, it can lead to desertification.

So, these two are the processes that can harm soil fertility.

Answer:

\(\boxed {\boxed {\sf 353 \ mL}}\)

Explanation:

We are asked to find the volume in milliliters of a solution, given the mass of solute and molarity of the solution.

Molarity is a measure of concentration in moles per liter.

\(molarity = \frac {moles \ of \ solute}{liters \ of \ solution}\)

We are given the mass of the solute. We must convert the mass to moles using the molar mass (the mass of 1 mole of a substance). These values are found on the Periodic Table. They are equal to the atomic masses, but the units are grams per mole instead of atomic mass units.

Look up the molar masses of the individual elements in calcium chloride.

The chemical formula, CaCl₂, has a subscript of 2. There are 2 moles of chlorine in 1 mole of calcium chloride. We must multiply chlorine's molar mass by 2 before adding calcium's molar mass.

Set up a conversion factor using the molar mass.

\(\frac {110.98 \ g \ CaCl_2}{1 \ mol \ CaCl_2}\)

Multiply by 45.0 grams of calcium chloride.

\(45.0 \ g \ CaCl_2 *\frac {110.98 \ g \ CaCl_2}{1 \ mol \ CaCl_2}\)

Flip the conversion factor so the units of grams of calcium chloride cancel.

\(45.0 \ g \ CaCl_2 *\frac{1 \ mol \ CaCl_2} {110.98 \ g \ CaCl_2}\)

\(45.0 \ *\frac{1 \ mol \ CaCl_2} {110.98}\)

\(\frac {45.0}{110.98} \ mol \ CaCl_2= 0.405478465 \ mol \ CaCl_2\)

Now we can find the liters of solution.

\(molarity = \frac {moles \ of \ solute}{liters \ of \ solution}\)

Substitute the values into the formula.

\(1.15 \ mol \ CaCl_2/L = \frac{0.405478465 \ mol \ CaCl_2}{x}\)

Cross multiply.

\(\frac {1.15 \ mol \ CaCl_2 /L}{1}= \frac{0.405478465 \ mol \ CaCl_2}{x}\)

\({1.15 \ mol \ CaCl_2 /L}*x= {0.405478465 \ mol \ CaCl_2} * 1\)

Divide both sides of the equation by 1.15 moles of calcium chloride to isolate the variable x.

\(\frac {1.15 \ mol \ CaCl_2/L *x}{1.15 \ mol \ CaCl_2 /L}= \frac{0.405478465 \ mol \ CaCl_2 * 1 }{1.15 \ mol \ CaCl_2/L }\)

\(x=\frac{0.405478465 \ mol \ CaCl_2 * 1 }{1.15 \ mol \ CaCl_2 /L}\)

The units of moles of calcium chloride cancel.

\(x=\frac{0.405478465 }{1.15 \ L }\)

\(x=0.35258997 \ L\)

There are 1000 milliliters in 1 liter.

\(\frac {1000 \ mL}{1 \ L}\)

\(0.35258997 \ L * \frac{1000 \ mL}{ 1 \ L}\)

\(0.35258997 * 1000 \ mL=352.58997 \ mL\)

The original measurements of mass and molarity have 3 significant figures, so our answer must have the same. For the number we found, that is the ones place. The 5 in the tenth place tells us to round the 2 up to a 3.

\(353 \ mL\)

D) the higher the frequency the greater the energy of light.

Explanation:

Energy and frequency of light are directly connected. The higher the frequency ,the greater the energy of light.

As frequency increases, the energy of light also increases.

Mathematically;

 Energy  = hf

   h is planck's constant

   f is the frequency.

The concentration of the solution is as follows;

H⁺ = 0.045 M

SO₄(²⁻) = 0.045 M

HSO₄⁻ = 0.155 M

Potassium hydrogen sulfate, KHSO₄ is a salt that will completely dissociate in water into its constituent ions, K+ and HSO₄⁻.

HSO₄⁻ ⇌ H⁺ + SO₄(²⁻)

Let's say x is the amount of HSO4- that dissociates. Then it will be

HSO₄⁻  = 0.20 - x

H⁺ = x

SO₄(²⁻) = x

Now, we can use the Ka for HSO4-, which is given as 1.3 x 10⁻². We will get the equation

Ka = (H⁺)(SO₄(²⁻)) / (HSO₄⁻ )

Substituting the expressions for the equilibrium concentrations gives:

1.3 x 10⁻² = (x)(x) / (0.20 - x)

So the concentrations are:

HSO₄⁻  = 0.20 - x = 0.20 - 0.045 = 0.155 M

H⁺ = x = 0.045 M

SO₄(²⁻) = x = 0.045 M

When ice is placed into a beaker filled with water, the water level does not drop because of the concept of displacement. When the ice is added, it displaces an amount of water equal to its own volume. This means that the ice takes up space in the beaker, pushing out an equal amount of water to make room for itself. Therefore, the total volume of water and ice in the beaker remains the same, and the water level does not drop.

This is due to the fact that the density of ice is lower than that of water and when the ice is placed into the water, it will float on the surface, pushing out an amount of water equal to its own volume.

Additionally, when the ice melts, it will release the same amount of water it displaced before and the water level will not change.
