Answer:
852000 J
Explanation:
The following data were obtained from the question:
Mass (M) = 600 g
Change in temperature (ΔT) = 2 °C
Specific heat capacity (C) = 710 J/g℃
Heat transfered (Q) =?
Thus, we can obtain the the heat transfered to the diamond by using the following formula:
Q = MCΔT
Q = 600 × 710 × 2
Q = 852000 J
Therefore, the energy transfered to the diamond by heat is 852000 J
Explanation:
The balanced chemical equation of the reaction is:
From the balanced chemical equation,
1 mole of propane forms ------ 3 mol. of 
gas.
The molar mass of propane is 44.1 g/mol.
One mole of any gas at STP occupies --- 22.4 L.
Hence, 44 g of propane forms (3x22.4 L=) 67.2 L of CO2 gas at STP.
Answer:
Thus, 67.2 L of CO2 is formed at STP.
This is the equation balanced:
<span>BaCl2(aq) + Na2CO3(aq) = BaCO3(s) + 2 NaCl(aq)
Then the coefficient in front of Na Cl is 2.
Answer: 2

Answer:
A. 0.31 mol NaNO2
Explanation:
Buffer solutions are the solutions that resist changes in pH on addition of small amount of acid or base.
Buffer solutions usually contain the mixture of a weak acid and its salt, or a weak base and its salt.
Among the options listed in the question, only NaNO2 is the salt formed from the nitrous acid.
