CaF2 + (NH4)2O --> 2 NH4F + CaO How many grams of NH4F can be formed from 34.6 grams of CaF2? (AKS 4f)

bixtya [17]

Answer:

32.83 grams of NH₄F can be formed from 34.6 grams of CaF₂

Explanation:

The balanced reaction is:

CaF₂ + (NH₄)₂O ⇒ 2 NH₄F + CaO

By stoichiometry of the reaction (that is, the relationship between the amount of reagents and products in a chemical reaction), the following quantities participate in the reaction:

CaF₂: 1 mole
(NH₄)₂O: 1 mole
NH₄F: 2 mole
CaO: 1 mole

Being the molar mass of the compounds:

CaF₂: 78 g/mole
(NH₄)₂O: 52 g/mole
NH₄F: 37 g/mole
CaO: 56 g/mole

Then by stoichiometry, the following amounts of mass participate in the reaction:

CaF₂: 1 mole* 78 g/mole= 78 g
(NH₄)₂O: 1 mole* 52 g/mole= 52 g
NH₄F: 2 mole* 37 g/mole= 74 g
CaO: 1 mole* 56 g/mole= 56 g

You can apply the following rule of three: if 78 grams of CaF₂ form 74 grams of NH₄F by stoichiometry, 34.6 grams of CaF₂ will form how much mass of NH₄F?

$mass of NH_{4} F=\frac{34.6 grams of CaF_{2} *74 grams ofNH_{4} F}{78grams of CaF_{2} }$

mass of NH₄F= 32.83 grams

32.83 grams of NH₄F can be formed from 34.6 grams of CaF₂

const2013 [10]

Hmm, well depending on your speed depends on what gear you select, and not much else related to manual transmissions specifically (if it wasn't just manuals it could be anything from air resistance to noise in the car).

So I'd assume that:
