Answer:
Ca generally loses two electrons from its outer shell to form a Ca2+ ion.
Answer:
tetrahedral geometry
<h3>CHCH2O- CH2CH3</h3>
Explanation:
There are several centers of interest. Each carbon with all single bonds is the center of a tetrahedral geometry.
Answer:
The gas obeys Boyle’s law and the value of
both are equal to 40.0 atm L.
Explanation:
Initial volume of the gas = 
Initial pressure of the gas = 
Final volume of the gas = 
Final pressure of the gas = 
This law states that pressure is inversely proportional to the volume of the gas at constant temperature.

The equation given by this law is:








The gas in the cylinder is obeying Boyle's law.
The gas obeys Boyle’s law and the value of
both are equal to 40.0 atm L.
The answer is 7.33 g.
<span>To calculate this, we will use the the ideal gas law:
PV = nRT
where
P - pressure of the gas,
V - volume of the gas,
n - amount of substance of gas,
R - gas constant,
T - temperature of the gas.</span>
Since the amount of substance of gas (n) can be expressed as mass (m) divided by molar mass (M), then:
PV = RTm/M
It is given:
P = 0.98 atm
V = 10.2 l
T = 26°C = 299.15 K
R = 0.082 l atm/Kmol (gas constant)
M (H2O) = 2Ar(H) + Ar(O) = 2*1 + 16 = 2 + 16 = 18g
m = ?
Since PV = RTm/M, then:
m = PVM/RT
m = 0.98 · 10.2 · 18 / 0.082 · 299.15 = 179.928/24.5303 = 7.33 g
