Answer:
includes the coefficients that are needed for balancing the equation.
Explanation:
Calculate the number of mole of 5O2:
1.2 x 5/4=1.5 mol
c - the molarity, n - the number of moles, V - the volume of the solution
First calculate the number of moles of AgNO₃ in the solution.
The volume is
.
The molarity:
.
The molarity is
0.016 mol/L.
Since there are 22.4 L/mol at STP, you would convert 1000mL to 1 L then divide that by 22.4, meaning your answer would be 0.0446 rounded to 0.04
Answer:
Q = 5350.2 Joules.
Explanation:
<u>Given the following data;</u>
Mass, m = 26. 5g
Initial temperature, T1 = 0°C
Final temperature, T2 = 48.3°C
Specific heat capacity of water, c = 4.18 J/g°C.
*To find the quantity of heat*
Heat capacity is given by the formula;
Where;
- Q represents the heat capacity or quantity of heat.
- m represents the mass of an object.
- c represents the specific heat capacity of water.
- dt represents the change in temperature.
dt = T2 - T1
dt = 48.3 - 0
dt = 48.3°C
Substituting the values into the equation, we have;
Q = 5350.2 Joules.
Therefore, the amount of heat absorbed is 5350.2 Joules.
