CoCl₂(s) → Co²⁺(aq) + 2Cl⁻(aq)
n(CoCl₂)=0.27 mol
n(Co²⁺)=n(CoCl₂)
n(Cl⁻)=2n(CoCl₂)
n=n(Co²⁺)+n(Cl⁻)=3n(CoCl₂)
n=3*0.27=0.81 mol
Answer : 20.63845
The dogs mass in kilograms is 20.63845
1 pound = 0.453592
Hope this Helps :)
Because there are 2 Cl on the left, we will put a coefficient 2in front of HCl on the right side to balance out the Cl. This would result in an unequal amount of H, with 6 on the right side and 7 in the left, so we have to put a coefficient of 2 in front of C6H5OH and C6H4OH on both sides to balance out the H. By doing this, we would obtain an equal amount of H on both sides. The Carbon is already balanced, and so is the Oxygen.

Measuring the Quantity of Heat
Calorimeters and Calorimetry
On the previous page, we learned what heat does to an object when it is gained or released. Heat gains or losses result in changes in temperature, changes in state or the performance of work. Heat is a transfer of energy.

Specific Heat Capacity
Suppose that several objects composed of different materials are heated in the same manner. Will the objects warm up at equal rates? The answer: most likely not. Different materials would warm up at different rates because each material has its own specific heat capacity. The specific heat capacity refers to the amount of heat required to cause a unit of mass (say a gram or a kilogram) to change its temperature by 1°C. Specific heat capacities of various materials are often listed in textbooks.

Answer:
4. is composed mostly of carbondioxide.
Explanation: It is has a more denser carbon dioxide layer and its hotter than that of Earth. Venus surface also consist of other layers of hazy layer and thick cloud of sulphuric acid droplets.
