Answer:
Beryllium Fluoride (BeF2) is an ionic compound
When copper (ii) oxide is heated in presence of hydrogen gas it produces copper metal and water vapor.
that is
CuO + H2 = Cu + H2O
The moles of copper metal produced is calculated as below
find the moles of CUO used
moles = mass/molar mass
=5.6/79.5 =0.07 moles
by use of mole ratio between CUO:Cu which is 1:1 the moles of Cu is also
=0.007 moles of Cu
A gas that occupies 4.31 litres at a pressure of 0.755 atm will have a temperature of 39.58°C. Details about temperature can be found below.
<h3>How to calculate temperature?</h3>
The temperature of a gas can be calculated using the following formula:
PV = nRT
Where;
- P = pressure
- V = volume
- n = number of moles
- R = gas law constant
- T = temperature
0.755 × 4.31 = 1 × 0.0821 × T
3.25 = 0.0821T
T = 3.25 ÷ 0.0821
T = 39.58°C
Therefore, a gas that occupies 4.31 litres at a pressure of 0.755 atm will have a temperature of 39.58°C.
