Answer: In order for the process of natural selection to occur, the population needs to have some genetic variation. The environment is the ultimate push factor, but if the population doesn't have genetic variation in it, than the species will die out.

Use this balanced equation to help you solve:
valentina_108 [34]

1. 842g of NaOH will form 547.3 g of Al(OH)₃

2. The yield is 93.55%

<u>Explanation:</u>

3NaOH + Al → Al(OH)₃ + 3Na

1.

Molar mass of NaOH = 40 g/mol

Molar mass of Al = 27 g/mol

Molar mass of Al(OH)₃ = 78 g/mol

According to the balanced equation:

3 moles of NaOH requires 1 mole of Al to form 1 mole of Al(OH)₃

The ratio of NaOH : Al : Al(OH)₃ = 3 : 1 : 1

3 X 40 g of NaOH reacts with 27 g of Al to form 78 g of Al(OH)₃

120 g of NaOH + 27g of Al → 78 g of Al(OH)₃

120g of NaOH form 78g of Al(OH)₃

1g of NaOH will form \frac{78}{120} g of Al(OH)₃

842g of NaOH will form \frac{78}{120} X 842 g of Al(OH)₃

                                   = 547.3 g of Al(OH)₃

Therefore, 842g of NaOH will form 547.3 g of Al(OH)₃

2. Only 512 g of Al(OH)₃ is formed

Yield % = ?

Yield = \frac{512}{547.3} X 100\\\\Yield = 93.55

Therefore, the yield is 93.55%

Please help I’ll give you the BRAINLIEST!
Simora [160]

Answer:

1. Number of moles in 3.63 * 10²² atoms of K = 0.06 moles

2. Number of moles in 5.96 g of BaCO₃ = 0.03 moles

3. Number of moles of NH₃ = 0.88 moles

4. Volume of CSI = 0.50 liters

Explanation:

1. One mole of K contains 6.02 * 10²³ atoms

Number of moles in 3.63 * 10²² atoms = (3.63 * 10²² atoms/6.02 * 10²³ atoms) * 1 mole

Number of moles in 3.63 * 10²² atoms of K = 0.06 moles

2. Number of moles = mass / molar mass

Molar mass of BaCO₃ = 197.33 g/mol; mass of BaCO = 5.96 g

Number of moles = 5.96 g/ 197.33 g/mol

Number of moles in 5.96 g of BaCO₃ = 0.03 moles

3. Number of moles = mass / molar mass

Molar mass of NH₃ = 17 g/mol; mass of NH₃ = 1.50 g

Number of moles = 1.50 g/ 17 g/mol

Number of moles of NH₃ = 0.88 moles

4. Chlorosulfonyl isocyanate, ClSO2NCO, otherwise known as CSI, is a reagent used in organic synthesis. It has a density of 1.626 g/cm³.

Volume = mass/density

mass = 82.0 g; density of CSI = 1.626 g/cm³

Volume = 82.0 g / 1.626 g/cm³

Volume = 50.43 cm³

Volume = 50.43 cm³/1000 cm³ * 1 liter

Volume of CSI = 0.50 liters
