Answer:
ZnO(s) + 2HCl(aq) ------> ZnCl2(aq) + H2O(l)
Na2O(s) + 2HCl(aq) -----> 2NaCl(aq) + H2O(l)
Rb2O(s) + 2HCl(aq) -----> 2RbCl(aq) + H2O(l)
NiO(s) + 2HCl(aq) --------> NiCl2(aq) + H2O(l)
MgO(s) + 2HI(aq) -----> MgI2(aq) + H2O(l)
Na2O(s) + 2HI(aq) -----> 2NaI(aq) + H2O(l)
CaO(s) + 2HI(aq) ----> CaI2(aq) + H2O(l)
Explanation:
Let us recall that the oxides of metals are basic in nature. These basic metal oxides can react with acids to form salt and water only.
In the reactions above, HCl and HI were reacted with different metal oxides and the corresponding salts of each metal and water was formed as shown.
Answer:
the correct answer is option ( B ) rocks cannot change their volume ,shape, and size
because a solid substance cannot change its, volume, shape and size
Hope it helps you
have a nice day
I'm not completely sure on this and I apologize if it's wrong, but I believe it's B) Newton's Law.
Answer:
2445 L
Explanation:
Given:
Pressure = 1.60 atm
Temperature = 298 K
Volume = ?
n = 160 mol
Using ideal gas equation as:
where,
P is the pressure
V is the volume
n is the number of moles
T is the temperature
R is Gas constant having value = 08206 L.atm/K.mol
Applying the equation as:
1.60 atm × V = 160 mol × 0.08206 L.atm/K.mol × 298 K
<u>⇒V = 2445.39 L</u>
Answer to four significant digits, Volume = 2445 L
