The answer is a because a fill in the blank is always just one word
For the first part, use the question M=mol/vol (liters)
To do this, you have the given 1.6 M solution
divide the 360g by the molar mass of ethanol (44.07) to get moles
360/44.07=8.16 mol
so
1.6M = 8.16 mol/x vol
volume: 5.1 Liters
Answer:
44.8 L
Explanation:
Using the ideal gas law equation:
PV = nRT
Where;
P = pressure (atm)
V = volume (L)
n = number of moles (mol)
R = gas law constant (0.0821 Latm/molK)
T = temperature (K)
At Standard temperature and pressure (STP);
P = 1 atm
T = 273K
Hence, when n = 2moles, the volume of the gas is:
Using PV = nRT
1 × V = 2 × 0.0821 × 273
V = 44.83
V = 44.8 L
I think it’s the first one. Electroplating means you put on a layer of metal on something.
Answer:
Zn+H2O ------ ZnO + H2 is the correct answer
