1.2m^3 = _________yd^3
1 answer:
1.57yd³
Explanation:
This is a conversion problem from m³ to yd³;
Given 1.2m³, convert to yd³
1m = 1.094yd
We are going to use a conversion factor of 1 to solve this problem;
m³ = m x m x m
1.2 m ³ = 1.2 x m x m x m x
= 1.57yd³

Answer:
1) Endothermic.
2)
3)
Explanation:
Hello there!
1) In this case, for these calorimetry problems, we can realize that since the temperature decreases the reaction is endothermic because it is absorbing heat from the solution, that is why the temperature goes from 22.00 °C to 16.0°C.
2) Now, for the total heat released by the reaction, we first need to assume that all of it is released by the solution since it is possible to assume that the calorimeter is perfectly isolated. In such a way, it is also valid to assume that the specific heat of the solution is 4.184 J/(g°C) as it is mostly water, therefore, the heat released by the reaction is:
3) Finally, since the enthalpy of reaction is calculated by dividing the heat released by the reaction over the moles of the solute, in this case NH4Cl, we proceed as follows:
