I believe the answer is carbon dioxide. Because when carbon dioxide and water combine in the atmosphere it forms a very weak acid called carbonic acid, which falls to the Earth's surface as precipitation.
Answer:
The population of the long-legged birds decreases.
Explanation:
The population of the short-legged birds increases whereas the population of long-legged birds decreases due to availability of food in that environment. The long-legged birds feed on fish whose population decreases due to drought conditions so the population of long-legged birds also decreases while on the other hand, the population of short-legged birds increases or remain the same because they feed on the insects and the insects are available in large amount and less affected by the drought conditions.
<u>Answer:</u> The reaction for the 
value of lead phosphate is given below and the value of solubility product for the same is 
<u>Explanation:</u>
Solubility product is defined as the product of concentration of ions present in a solution each raised to the power its stoichiometric ratio. It is expressed as
The chemical formula of lead phosphate is 
The equation for the hydration of the lead phosphate is given as:
The solubility product of lead phosphate is . This means that it is highly insoluble in water as the solubility product is very very low.
Hence, the reaction for the value of lead phosphate is given above and the value of solubility product for the same is
