Chemistry
1 answer:
Paladinen [302]3 years ago
7 0

Answer:

6.22g of CaCl₂

Explanation:

Mass of HCL = 4.09g

Mass of CaCl₂ =

equation of reaction

2HCl + Ca(OH)₂ → CaCl₂ + 2H₂O

From equation of reaction, 2 moles of HCl produces 1 mole of CaCl₂

2(36.5)g of HCl = 111g of CaCl₂

73g of HCl will produce 111g of CaCl₂

4.09g of HCl will produce = x

73g of HCl = 111g of CaCl₂

4.09g of HCl = x

Cross multiply and solve for x

X = (111 * 4.09) / 73

X = 6.219g of CaCl₂ = 6.22g of CaCl₂

4.09g of HCl will produce 6.22g of CaCl₂

A small container of perfume is opened in a classroom. Soon every student in the room smells the perfume. Explain this in terms
iogann1982 [59]

When perfume or cologne is sprayed into the air, it turns into a gas and its particles mix with other air particles that quickly move around the room. This is because gas is the least dense of the three states of matter. It moves quickly into any space or volume because it has the least density. This is called diffusion, when molecules or particles move from areas with high concentration to low concentration areas.

A compound is found to contain 43.66% of P and 56.33% of O.
jek_recluse [69]

Answer: P2O5 is the empirical formula.

Explanation: When given percentages you can assume that many grams of each atom are in the compound. Then you divide grams by the molar mass of each element, giving you moles. Once you have moles, divide by the smaller molar amount, which should give you 1 mol of Phosphorus and 2.5 mol of Oxygen. Then multiply by 2 in order for both moles to be a whole number. This gets you 2 and 5.
