Answer:
1. CaCO3(s) <=> CaO(s) +CO2 (g) Delta H = +178 kJ/mol
Since Delta H is positive, it means the reaction is endothermic
a. An increase in temperature will will shift the equilibrium position to the right, thus forming more products
b. A decrease in the temperature will shift the equilibrium position to the left, thus forming more reactants
2. PCl3(g) + Cl2(g) <-> PCl5 (g) Delta H= -88 kJ/mol
From the above, Delta H is negative which implies exothermic reaction.
c. Increasing the temperature will shift the equilibrium position to the left, thus forming more reactants.
d. Decreasing the temperature will shift the equilibrium position to the right, thus forming more products
Hello!
A substance that could be found in air, water or soil that is harmful to humans or animals is a Pollutant.
The other substances cannot be found in air, water or soil. Fossil fuels can only be found in soil, smog can only be found in the air, and carbon dioxide can be found in the water or air.
Pollutants are substances that have harmful effects and damage the environment. Some examples of pollutants are Carbon Monoxide (air), Lead (soil) and Insecticides (water).
Have a nice day!
Answer:
B's acceleration is half that of A
Explanation:
The force equation is;
Force = mass × acceleration
According to Newton's second law of motion, which explains the relationship between acceleration and mass of an object, an inverse relationship exists between the mass and the acceleration. For the same amount of force, an increase in mass (m) means a constant decrease in acceleration (a) of the object. In other words, if the mass of an object increases by two times, the acceleration will decrease by two times.
In this case involving objects A and B which has the same amount of force applied, object B has TWICE the mass of A. Using Newton's second law, this means that object B's ACCELERATION WILL BE HALF OF THAT OF OBJECT A.
