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
So 14 miles per gallon of gas
Answer:
30
We'll be using the 5 numbers in your question.
In order to solve this problem, we need to know what range is.
The range is the spread of your data from the <u>lowest</u> to the <u>highest</u> value.
In order to find the range, we need to order the values from least to greatest.
Note: No picture of the stem-and-leaf plot is given in the question.
From least to greatest:
2, 5, 14, 19, 32.
Next, find the maximum and the minimum values.
Minimum: 2
Maximum: 32
Lastly, subtract the maximum and the minimum:
32-2=30.
Your range is 30.
