Answer: Because water has a high specific heat capacity due to the hydrogen bonding within the H₂O molecules ; so it takes a great deal of energy, or heat, to break these bonds— or to form them.

Explanation:
Here we have to use stoichiometry.
First of all, we have to calculate the mass of 100% of yield:
1.7 g ------- 98%
X -------- 100%
X = 1.73 g (approximately)
Second, we have to calculate the mass of N2 that is necessary to react to produce the mass of 1.73g of NH3. To do that, we have to use the Molar mass of N2 and NH3 and don't forget the stoichiometric relationship between them.
Molar Mass N2 : 14x2 = 28 g/mol
Molar Mass NH3: 14 + 3 = 17 g/mol
28g (N2) ------- 17x2 (NH3)
X ------------ 1.73 g
X = 1.42 g (approximately)
The answer is -11.2 fahrenheit.
Answer:
Explanation:
(a) Balanced reaction of gallium with oxygen is as follows:
(b) 
Multiply the carbon dioxide by 6 to balance carbon as follows:
After that multiply H2O by 7 to balance hydrogen as follows:
Finally balance oxygen by multiplying O2 by 19/2. Therefore, balanced reaction is as follows:
(c) 
first balance calcium, by multiply 
by 3 as follows:
After that balance phosphorous by multiplying 
by 2 as follows:
Finally balance Na by multiplying NaCl by 6. Therefore, balance reaction is as follows:
