Answer:
0.0702J/g°C the specific heat capacity of the metal.
Explanation:m

where,
Q = heat absorbed by metal = 186.75 J
= Mass of metal= 19 g
= Initial temperature of metal = 
=Final temperature of metal = 
= specific heat of metal= ?



0.0702J/g°C the specific heat capacity of the metal.
C+O2=CO2. The 2 would be smaller than the chemical symbol. Hope this helped
The chemical equation for the combustion of methane is CH4 + 2O2 --> CO2 + 2H2O.
The coefficients of that equation are 1, 2, 1, and 2, in the order you asked for.
I want to say 8 but i'm not sure. I just did a lesson on this and my notes say it could be 8 but then again I'm not sure.
Answer:
A. 3.2L of NO
B. 4.8L of H2O
Explanation:
We'll begin by writing the balanced equation for the reaction. This is given below:
4NH3 + 5O2 —> 4NO + 6H2O
A. Determination of the litres of NO produced from the reaction. This is illustrated below:
From the balanced equation above,
5L of O2 produced 4L of NO.
Therefore, 4L of O2 will produce = (4x4)/5 = 3.2L of NO.
B. Determination of the litres of H2O produced from the reaction. This is illustrated below:
From the balanced equation above,
5L of O2 produced 6L of H2O.
Therefore, 4L of O2 will produce = (4x6)/5 = 4.8L of H2O
