Answer:
Explanation:
Let's just get the answer and then show why the others are wrong.
The answer is C.
The number of reactants and Products need not be the same
C3H8 + 5O2 ===> 3CO2 + 4H2O
The reactants = 1 + 5 = 6
The products = 3 + 4 = 7
So A is incorrect.
================
B is saying that
C3H8 + 5O2 ===> C3H8 + 5O2
The answer is obviously not B
======================
C8H18(l) + O2(g) ==> CO2(g) + H2O(g) unbalanced
Gasoline is a liquid. All the rest are gases. D is wrong.
=================
C is correct
The left side has
3 Cs
8 Hs
and 10 Os
The right side has
3Cs
8Hs
10 Os
As h(x) approaches 10+ the limit is given as 18.5
<h3>What is limit in mathematics?</h3>
The limit in mathematics has to do with the value that a function would approach as the input in the limit approaches a particular value.
It is when a function would be made to approach output at a particular input value. The concept is very important in calculus as well as analysis in mathematics. They help to define integrals, derivatives as well as continuities in mathematics.
<h3>How to solve for the limit</h3>
The x equation that we have in the question is given as
x = (10+n)
We are to find the limit of lim h(10+n)
This is as h tends towards 10.
h→10
When we go to the table we would observe what happens as 10 moves towards this value. In the given table we would have h as it tends towards 10. In the right hand side of this table we would see that as X is moving towards 10, the value changes to 18.5
Hence the answer to this question is 18.5

Looking at the image attached, When the distance from a to b was increased, the pitch of the sound would be lower.
<h3>What is the pitch of a sound?</h3>
The pitch of a sound is known to be how high or low the sound that is played is.
A high sound is known as a sound that has a high pitch and a low sound is known to be the one that has a low pitch. In the above picture, the pitch will be lowered when the distance is increased.
