Answer:
Magnesium chloride/Molar mass
95.211 g/mol
Explanation:
Answer:
The number of moles of CO2 is 0,54
Explanation:
We use the formula PV=nRT. The conditions of STP are 1 atm of pressure and 273 K of temperature.
PV=nRT n=PV/RT
n=1 atm x 12 L/0,082 l atm/K mol x 273K
n=0,536049316 moles
You have to find how many moles of H2 has formed.
C+ H2O -> CO + H2
mole of carbon reacted = mass / molar mass = 34g/ 12g per mol = 2.83 mol
for every 1 mole of carbon will form 1 mole of H2
mole of hydrogen produced = 1* 2.83 = 2.83 mol
mass of hydrogen = mole * molar mass = 2.83 mol * (1*2) = 5.66g

Answer:
D. 3.844 x 10^5
3.844 is between 1 and 10, so that is correct.
Not C because if it is negative it would be a decimal from 0 e.g -> 0.88
