In order to determine the mole ratio, you need to begin with a balanced chemical equation.
Answer:
Magnesium oxide is a simple basic oxide, because it contains oxide ions. It reacts with water to form magnesium hydroxide which is a base.
<u>Answer:</u> The balanced chemical equation is 
<u>Explanation:</u>
A balanced chemical equation is one where all the individual atoms are equal on both sides of the reaction. It follows the law of conservation of mass.
For the given unbalanced chemical equation:
<u>On the reactant side:</u>
Atoms of K = 1
Atoms of Cl = 1
Atoms of O = 3
<u>On the product side:</u>
Atoms of K = 1
Atoms of Cl = 1
Atoms of O = 2
To balance the equation, we must balance the atoms by adding 2 infront of both 
and 
. Also, a coefficient of 3 must be written infront of 
For the balanced chemical equation:
Answer:
904.014 j/kgk
Explanation:
Mass of metal = 45g
Temperature of metal = 85.6°
Mass of water = 150
Temperature of water = 24.6
Final temperature of system = 28.3
Heat lost by metal = Heat gained by water
m1 * c1 * dt = m2 * c2 * dt
Q = quantity of heat
Q = m*c*dt
dt = change in temperature
dt of water = 28.3 - 24.6 = 3.7
dt of metal = 85.6 - 28.3 = 57.3
Specific heat capacity of water, c = 4200
(45 * 10^-3) * c * 57.3 = (150 * 10^-3) * 4200 * 3.7
2.5785c1 = 2331
c1 = 2331 / 2.5785
= 904.01396
= 904.014 j/kgk
Answer:
Explanation:
193.02 times 9.55 it's going to be 1843.341
9.55= 191.20 milli
