Explanation:
(6.1). The reaction equation will be as follows.
Assuming the value of 
as 
and let the solubility of each specie involved in this reaction is "s". The expression for will be as follows.
![K_{sp} = [Ba^{2+}][SO^{-}_{2}]](https://tex.z-dn.net/?f=K_%7Bsp%7D%20%3D%20%5BBa%5E%7B2%2B%7D%5D%5BSO%5E%7B-%7D_%7B2%7D%5D)
(Solids are nor considered)
= 
s = 
= 
= 
Therefore, solubility of barium sulfate in water is .
(6.2). As the molar mass of 
is 233.38 g/mol
Therefore, the solubility is g/L will be calculated as follows.
= 
Therefore, solubility of barium sulfate in grams per liter is .
Answer: The velocity of the first ball is 0.875 m/s if the second ball travels at 1.5 m/s after collision.
Explanation:
Given: 
= 0.2 kg, 
= 0.15 kg
= 2 m/s, 
= 0 m/s, 
= ?, 
= 1.5 m/s
Formula used is as follows.
where,
v = velocity before collision
v' = velocity after collision
Substitute the values into above formula as follows.
Thus, we can conclude that the velocity of the first ball is 0.875 m/s if the second ball travels at 1.5 m/s after collision.
Answer:
option D= it makes the reaction harder to start.
Explanation:
Activation energy:
It is the minimum amount of energy required by chemical specie to start the chemical reaction.
Explanation:
The activation energy is inversely related to the rate of reaction. The higher the activation energy the slower will be the reaction rate.
Molecules are colloid with each other and gain kinetic energy if this energy is higher than the transition state energy then molecules easily undergo the chemical reaction. Because molecules easily overcome the barrier i.e transition state.
When the kinetic energy is lower than molecules can not pass the barrier. They require the input which is called activation energy to pass the barrier.
The higher the activation energy, the difficult for the reaction to proceed. Catalyst are used to lower the activation energies because in this way lower will be the transition state, and higher will be the reaction rate.
Most foods that are high in calcium are poor sources of iron. this statement illustrates the characteristic of a nutritious diet known as balance.
Nutrition is the biochemical and physiological processes by which organisms use food to sustain life. It provides organisms with nutrients that can be metabolized to produce energy and chemical structures. An inadequate supply of nutrients leads to malnutrition.
Although these two definitions may seem similar, there are differences. Health simply means food that protects you from disease and keeps you alive. Nutrient-rich foods mean foods that provide sufficient nutrients (vitamins, carbohydrates, proteins) that the body needs to survive the kind that is either low in fiber or high in fat, salt, and/or sugar. Eating too much food or drink.

Answer/Explanation:
A geyser is hot water erupting from a vent in the earth. Geysers are somewhat rare and occur in certain parts of the earth. Underneath, there are hidden chambers that provide constant flows of water. Sometimes when the tectonic plate of the earth move, it leaves gaps in between the hot earth's inner core and the ground. The magma inside is able to heat up the water from the earth. Since hot particle tend to rise, the water explodes out of the vent with such power from the heat.
