Answer:
Acid + Base -------> Salt + Water
Explanation:
The reaction between an acid and bases is called a neutralization reaction. The result of the reaction is salt and water. For example, when hydrochloric acid(acid) and sodium hydroxide(base) react they form sodium chloride(salt) and water. Also, heat is evolved.
Example:
HCl + NaOH ----------> NaCl + H2O
HCl is hydrochloric acid.
NaOH is sodium hydroxide which is a base.
NaCl is sodium chloride which is a salt.
H2O is water.
Explanation:
Formula for black body radiation is as follows.
where, P = power emitted
A = surface area of black body
= Stephen's constant = 
As area is given as 1.0 
. Converting it into meters as follows.
(as 1 m = 100 cm)
= 
It is given that P = 201 watts. Hence,
= 
= 
T = 
= 8862.5 K
Thus, we can conclude that the temperature of the surface is 8862.5 K.
Sodium is a solid and a liquid

Answer:
A
Explanation:
A linear correlation means the increase in one variable cause an increase in the other variable. In a graph, the linear correlation can be demonstrated by a right-slanted straight diagonal line. Therefore if an increase in carbon dioxide causes a directly proportional increase in global temperatures then the two are correlated.
