The correct answer for the given question is B. Heat is written as a reactant in the equation.
<h3>What is endothermic reaction?</h3>
An endothermic reaction is a reaction in which is reactants absorbs heat from the surrounding to give the product or heat supplied is the reactant.
Suppose if A and B are reactants that forms product C and D,
and H be the heat absorbed or supplies to the reactants.
Then for an endothermic reaction we can write-
A + B + Heat ---> C + D
Since, Heat is absorbed at the reactant side then it is called as endothermic reaction.
Hence,the correct answer for the given question is B. Heat is written as a reactant in the equation.

1 and 1/15
Work backwards, so add 7/18 to 1 5/6 first (I'm gonna add them in improper fraction form to make it easier) and you get 40/18 which is 20/9
Then multiply by 1 1/5 (or 6/5) to get 120/45 which simplifies to 8/3
Then divide by 2 1/2, or 5/2, which means you multiply by the reciprocal (2/5)
8/3 times 2/5 equals 16/15 or 1 1/15
Answer:
4/81
Step-by-step explanation:
So first, the probability that she gets a 3 first is 1/9, because there is only 1 card out of 9 total cards.
Next, the probability that she gets a multiple of 2 is 4/9, because there are 4 different things she can pick (2, 4, 6, 8) out of the total 9 cards.
The last step is to multiply the two, so 1/9 * 4/9 = 4/81.
