It means there are two chlorine molecules and there is only one magnesium molecule (because no subscript really just means there is an invisible 1 that isn't listed).
Explanation:
Let x = distance of 
from the fulcrum and let's assume that the counterclockwise direction is positive. In order to attain equilibrium, the net torque 
about the fulcrum is zero:
Solving for <em>x</em>,
Answer:
Explanation: relationship between the object and the observer's frame of reference.
Since there is no temperature change which drives heat flow, thus no heat will be released by the water.
<h3>
Heat released by the water when it freezes</h3>
The heat released by the water when it freezes is calculated as follows;
Q = mcΔФ
where;
- m is mass of water
- c is specific heat capacity of water
- ΔФ is change in temperature = Фf - Фi
when water freezes, the temperature, Фf = 0 °C
Q = 82 x 4200 x (0 - 0)
Q = 0
Since there is no temperature change which drives heat flow, thus no heat will be released by the water.
