Cu20(s) + C(s) - 2Cu(s) + CO(g)
Romashka-Z-Leto [24]

Answer:

That means Cu2O is limiting reagent and C is excess reagent

Explanation:

Based on the reaction, 1 mole of Cu2O reacts per mole of C. The ratio of reaction is 1:1.

To solve this question we need to convert the mass of each reactant to moles. The reactant with the lower amount of moles is limiting reactant and the excess reactant is the reactant with the higher number of moles.

<em>Moles Cu2O -Molar mass: 143.09 g/mol-</em>

114.2g Cu2O * (1mol / 143.09g) = 0.798 moles Cu2O

<em>Moles C -Molar mass: 12.01g/mol-</em>

11.1g C * (1mol / 12.01g) = 0.924 moles C

<h3>That means Cu2O is limiting reagent and C is excess reagent</h3>

How many molecules are in 1.2 moles of H20?​
Otrada [13]
<h3>Answer:</h3>

7.226 × 10^23 molecules.

<h3>Explanation:</h3>
  • A compound is a substance that is made by two or more atoms from different elements.
  • A mole of a compound contains a number of molecules equivalent to Avogadro's number,  6.022 × 10^23.
  • That is, one mole of a compound contains 6.022 × 10^23 molecules.

In this case we are given;

Number of moles of H₂O as 1.2 moles

But, 1 mole of H₂O contains 6.022 × 10^23 molecules.

We are required to calculate the number of molecules present;

  • To calculate the number of molecules we are going to multiply the number of molecules in one mole by the number of moles.
  • Therefore;

Number of molecules = 1.2 moles × 6.022 × 10^23 molecules/mole

                                    = 7.226 × 10^23 molecules.

Thus, 1.2 moles of water contains 7.226 × 10^23 molecules.

What mass of AgCl is produced when 53.42 g of AgNO3 reacts with 14.19 g of NaCl?
Leya [2.2K]

Answer is: mass of silver chloride is 34,82 g.

Chemical reaction: AgNO₃ + NaCl → AgCl + NaNO₃.

<span>m(AgNO</span>₃) = 53,42 g..<span>
m(NaCl) = 14,19 g.
n(AgNO</span>₃) = m(AgNO₃) ÷ M(AgNO₃).<span>
n(AgNO</span>₃) = 53,42 g ÷ 169,87 g/mol.

n(AgNO₃) = 0,314 mol.

n(NaCl) = 14,19 g ÷ 58,4 g/mol.

n(NaCl) = 0,242 mol; limiting reactant.

From chemical reaction: n(NaCl) : n(AgCl) = 1 : 1.<span>
n</span>(AgCl)<span> = 0,242 mol.
m</span>(AgCl) = 0,252 mol · 143,32 g/mol.

m(AgCl) = 34,82 g.
