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
Based on the amount of cheese used for the pizzas, the following are true:
- a. Mai uses 2.5 ounces of cheese per pizza.
- b. Mai will need 37.5 ounces for 15 pizzas.
<h3>Cheese used per Pizza. </h3>
This can be found as:
= Ounces of cheese used / Number of pizzas
= 10 / 4
= 2.5 ounces per pizza.
<h3 /><h3>Cheese needed for 15 pizzas. </h3>
= Number of pizzas x Cheese per pizza
= 15 x 2.5
= 37.5 ounces of cheese.
In conclusion, Mai needs 37.5 ounces of cheese to make 15 pizzas.

<h3 /><h3>How do rock types contribute to the rate of weathering?</h3>
<h3>Answer
<em>;</em><em> </em><em> </em><em>Certain types of rock are very resistant to weathering. Igneous rocks, especially intrusive igneous rocks such as granite, weather slowly because it is hard for water to penetrate them. Other types of rock, such as limestone, are easily weathered because they dissolve in weak acids.</em></h3>
