Answer is: 15675 J.
m (H₂O) = 75g - mass.
ΔT (H₂O)<span> = 75</span>°C - 25°C = 50°C -<span> change in temperature.</span>
C (H₂O) = 4,18 J/g·°C - <span>specific heat of water.
</span>Q = m·C·<span>ΔT.
Q- heat (in Joules-J).
</span>Q = 75g · 50°C · 4,18 J/g·°C = 15675J = 15,675 kJ.
Heat transfer<span> is a discipline that study</span><span> exchange, generation, use and conversion of </span>thermal energy<span> (</span>heat<span>) between physical systems.</span>
The given equilibrium reaction is,
According to Le Chatelier's principle states that when a system in equilibrium is disturbed by varying conditions like concentration, pressure, and temperature of the system, the system tries to counter act the affect by shifting the equilibrium towards the required side.
When 
is removed from the system, the concentration of chlorine () decreases, the equilibrium is disturbed. So, the system tries to re-establish the equilibrium by moving in that direction which produces more of chlorine, that is towards the reactant side.
The correct answer would be: 1. reaction would go to the left, making more "reactants"
Answer:
C, A, D and B
Explanation:
Water evaporates from the surface of the oceans leaving behind salts. As water vapor rises, it collects and is stored in clouds.
As water cools in the clouds, condensation occurs. Condensation is when gases turn back into liquids.
Condensation creates precipitation. Precipitation includes rain, snow, hail and sleet. The precipitation allows the water to return again to the Earth's surface.
When precipitation lands on land, the water can sink into the ground to become part of our underground water reserves, also known as groundwater.
A colorless, toxic, radioactive gas is called, bioaccumulation.
