Which of the following statements best compares nuclear power and hydropower based on their rates of renewal?

Hydropower has a faster rate because water is continuously being recycled through the hydrogeological cycle.
Nuclear power has a faster rate because all elements are spontaneously radioactive and are a source of nuclear energy.
Hydropower has a slower rate because a large volume of water vapor that evaporates takes several years to return to water cycle.
Nuclear power has a slower rate because the nuclear waste produced is not radioactive and thus cannot be used further as a fuel.

Answers

Answer 1

Hydropower is best compared to nuclear power based on their rates of renewal.

Because water is continually regenerated through the hydrogeological cycle, hydropower has a higher rate.Because all elements spontaneously produce radioactive material, which is a source of nuclear energy, nuclear power has a higher rate.Because it takes a significant amount of evaporated water several years to return to the water cycle, hydropower has a slower rate.Because the nuclear waste generated by nuclear power cannot be recycled as fuel and is not radioactive, it produces waste at a slower pace.

What is hydropower's primary source?Water in motion generates hydroelectricity, namely the winter and spring runoff from mountain streams and crystal-clear lakes. Water can be utilized to turn turbines and generators that produce power when it is falling due to gravity.

What is the relationship between mass, volume and density of a substance?

The mass of a substance is the quantity of matter present in that substance.

The volume of a substance is the amount of space a given mass of that substance occupies.

The density of a substance is the ratio of the mass and a given volume of that substance.

Therefore, the relationship between mass, volume and density is given below as:

Density = mass/ volume

From the data provided:

volume of the marshmallow = 2.75 in³

1 inch³ = 16.39 cm³

volume in cm³ = 16.39 * 2.75

volume of the marshmallow = 45.07 cm³

density of the marshmallow = 0.242 g/cm³

Mass of the marshmallow = volume × density

Mass of the marshmallow = 0.242 g/cm³ * 45.07 cm³

For this and the following two questions, determine the density of a substance (in g/dL) of a sample with a mass of 8.3 x 10-1 dag and a volume of 4.10 mL. What is the right-most significant figure after performing the calculation in scientific notation?

Answers

The density of a substance (in g/dL) of a sample with a mass of 8.3 x 10-¹ dag and a volume of 4.10 mL is 202.44g/dL.

How to calculate density?

The density of a substance is the measure of the mass of matter contained by a unit volume.

The density of a substance can be calculated by dividing the mass of the substance by its volume.

According to this question, a substance with a mass of 8.3 x 10-¹ dag has a volume of 4.10 mL. The density can be calculated as follows:

1 dag = 10g0.83 dag = 8.3g

1 millilitre = 0.01 decilitre4.10millitre = 0.041 deciliter

Density = 8.3g ÷ 0.041dL

Density = 202.44g/dL

Therefore, the density of a substance (in g/dL) of a sample with a mass of 8.3 x 10-¹ dag and a volume of 4.10 mL is 202.44g/dL.

8. A 9.7 ounce milk shake costs $3.45. There are 16 ounces in a pound. Determine the cost of a 5.5kg milkshake.

(454g per pound)
(10^-3 kilo unit = 1 unit)

Answers

The cost of a 5.5kg milkshake if 9.7 ounce milk shake costs $3.45 is $68.915.

Cost of 9.7 ounce milk shake = $3.45

Conversion of ounces into pound

One pound is equal to 16 ounces.

1ounces contain 1/16 pound.

9.7 ounces contain (1/16) × 9.7 pound.

9.7 ounces contain 0.606 pounds.

Cost of 0.606 pounds milk shake = $3.45

Conversation of pound into Gram

1 pound = 454g.

0.606 pounds = 454 × 0.606g

0.606 pounds = 275.12g

Conversation of gram into kilogram

1gram = 10^-3 kilo gram

275.12 gram = 275.12 × 10^-3 kilo gram

So, cost of 0.27512 kg milk shake = $3.45

cost of 1 kg milk shake = $3.45/ 0.27512 = $12.53

cost of 5.5 kg milk shake = $12.53 × 5.5 = $68.915

Thus, we calculated that the cost of a 5.5kg milkshake if 9.7 ounce milk shake costs $3.45 is

$68.915.

Gold has an atomic mass of 197.0 grams per mole. How many moles of gold is 10 grams? How many gold atoms are found in 10 grams of gold?

Answers

How many moles of gold is in 10 grams?

You first take 10g of Gold and divide it by 197.0 g of gold (it’s atomic mass)
this should give you about 0.051 moles of Gold

How many gold atoms are found in 10 grams of gold?

First you would take 10g of gold and divide it by 197.0g of gold then you would multiply that number (number of moles in 10g of gold) by Avogadro’s constant 6.022x10^23
You should get about 3.06x10^22 atoms of gold

What is the mass in grams of 0.05 moles of gold?

Answers

The mass of 0.05 mole of gold is 9.85 grams.

Equation :

The following equation relates the mass and molar mass of a substance to its mole:

Mole = mass /molar mass

We can determine the mass of gold using the formula above. This is attainable as follows:

0.05 mole = gold in one mole.

Molar mass of gold = 196.97 g/mol

Mole = mass / molar mass

0.05 = mass / 196.97

Mass = 0.05 × 196.97

Mass of gold = 9.85 g

Hence, the mass of the gold is 9.85 g.

Answers

The pOH of a solution that contains the given volume and mass is 1.690.

Equation :

To calculate pOH of sulfuric acid we must know the moles and concentration.

So, to calculate moles using formula,

moles = mass / molecular mass

Given,

mass = 3.5 g

volume = 1.75 lit

So,

moles of sulfuric acid = mass / molecular mass

Putting values,

moles of sulfuric acid = 3.5g / 98.079 g/mol

moles of sulfuric acid = 0.0357mol

Now to know the concentration we are using the formula,

Concentration of sulfuric acid = moles / volume

Putting values,

Concentration of sulfuric acid = 0.0357mol / 1.75l

Concentration of sulfuric acid = 0.0204 mol/l

Density is the measure of an object's mass per unit volume. Kilograms per cubic meter (kg/m³) is the SI unit for density.
