Convert mass to moles for both reactants. 2.50g CuCl2 0.50g Al

Chemistry
1 answer:
alexandr402 [8]3 years ago
6 0

Answer:

Number of moles of Al = 0.02 mol

Number of moles of CuCl₂ = 0.02 mol

Explanation:

Given data:

Mass of CuCl₂ = 2.50 g

Moles of CuCl₂ = ?

Solution:

Formula:

Number of moles = mass / molar mass

Molar mass of CuCl₂  =  63.546 + 35.5 ×2

Molar mass of CuCl₂  =  134.546 g/mol

Now we will put the values in formula:

Number of moles = 2.50 g / 134.546 g/mol

Number of moles = 0.02 mol

Given data:

Mass of Al = 0.50 g

Moles of Al = ?

Solution:

Formula:

Number of moles = mass / molar mass

Molar mass of Al  =  27 g/mol

Now we will put the values in formula:

Number of moles = 0.50 g / 27 g/mol

Number of moles = 0.02 mol

A factory discharges clean, warm water into a nearby stream. Fish keep dying in this part of stream. Explain why.
Ostrovityanka [42]

Answer:

the fish can't survive in that warm water

Explanation:

when the factory puts that warm water into the stream where the fish live they changed their environment. by adding unknown chemicals and changing the temp of the water the fish start to die.

The fish aren't used to living in that warm water, and if they can't adapt fast enough they will die, also the unknown chemicals that could be in the water will act as a poison for them making that stream unable to support any life.

Calculate how many grams of the product form when 16.7 g of calcium metal completely reacts. Assume that there is more than enou

39.96 g product form when 16.7 g of calcium metal completely reacts.

<h3>What is the stoichiometric process?</h3>

Stoichiometry is a section of chemistry that involves using relationships between reactants and/or products in a chemical reaction to determine desired quantitative data.

Equation:

Ca(s) + Cl_2(g) → CaCl_2(s)

In this case, for the undergoing reaction, we can compute the grams of the formed calcium chloride by noticing the 1:1 molar ratio between calcium and it (stoichiometric coefficients) and using their molar mass of 40 g/mol and 111 g/mol by using the following stoichiometric process:

m_{ca_C_l_2}= 16.7 g Ca x \frac{1 mol \;of \;Ca}{40g Ca} x \frac{1 mol \;of \;CaCl_2}{1 mol \;Ca} x \frac{111g of \;CaCl_2}{1 mol \;CaCl_2}

m_{ca_C_l_2} = 39.96 g

Hence, 39.96 g product form when 16.7 g of calcium metal completely reacts.

Hydrophobic compounds dissolve in
Anastaziya [24]
Hydrophobic molecules tend to be nonpolar molecules that group together to form micelles rather than be exposed to water. Hydrophobic molecules typically dissolve in nonpolar solvents (e.g., organic solvents).
