Answer:
Nope. should be 2NaCl + H₂ ⇒ 2Na + 2HCl
Explanation:
balance both sides of the equation.
Answer:
alkali metals
Explanation:
they all react vigorously or even explosively with cold water, resulting in the displacement of hydrogen.

Explanation:
the vapor pressure of a liquid at temperature range of 200K to 260K was found to fit the expression ln(p/torr)=16.255 - 2501.8/(T/K).
Answer:
<u>T2 = 745 K</u>
Explanation:
This is an ideal gas law problem. We can use this formula to find our answer:
(P1*V1)/T1 = (P2*V2)/T2
So we have these given in the problem:
P1 = 78 atm P2 = 45.2 atm
V1 = 21 L V2 = 30.0 L
T1 = 900 K T2 = ?
So we put all of this stuff into the equation and solve for the unknown T2:
[(78 atm)*(21 L)]/(900 K) = [(45.2 atm)*(30.0 L)]/T2
(1638 atm*L)/900 K = (1356 atm*L)/T2
1.82 atm*L/K = (1356 atm*L)/T2
[flip around to put T2 on the numerator and alone]
T2 = (1356 atm*L)/1.82 atm*L/K
[atm*L cancel out to leave us with K]
T2 = 745.0549451
<u>T2 = 745 K</u>
