Answer:
22
Explanation:
The atomic number indicates the amount of protons, so it would be 22
Biotic factors are living factors in an ecosystem while abiotic factors aren't living
A bowling ball weighing 7 pounds
Answer:
Second order
Explanation:
Given that:
When the reaction A → B + C is studied, a plot 1/[A]t vs. time gives a straight line with a positive slope.
From the integration method for the second order of reaction.
Suppose that:
rate = k₂[A]²
∴

Therefore, a plot of the linear function
versus t will be linear with a positive slope k₂ and the intercept on the concentration axis will be 
The linear plot for a second order reaction can be seen in theimage attached below.
Answer:
Butane and benzene are both compounds. They contain multiple elements bonded together in a specific ratio. Kerosene and gasoline are mixtures because they are combinations of several compounds. Oxygen is an element because it is made up of only one type of atom.
