Answer:
A. Atomic Number
Explanation:
The mass number is used to calculate the number of neutrons & electrons in one atom of an element. In order to calculate the number of neutrons you must subtract the atomic number from the atomic mass.
Answer:
B ) Superscript 24 subscript 11 upper N a right arrow superscript 24 subscript 12 upper M g plus superscript 0 subscript negative1 e.
Explanation:
Answer:
Methanol is produced as product of the reaction.
Explanation:
Methyl bromide contains a good leaving group 
because of high polarizability of Br atom and weak C-Br bond.
is a strong base as well as strong nucleophile due to small size and high electronegativity of oxygen atom.
Here methyl bromide primarily acts as an electrophile instead of an acid because of it's very weak acidity.
So, acts as nucleophile towards methyl bromide by replacing bromide ion and forms methanol.
Reaction goes through 
mechanism.
Structure formula of product has been given below.
You would get yy x yy cross
Answer:
1.
Rainforests are important due to the amount of oxygen the tree's produce. It also adds biodiversity and more balance in the food chain of animals.
2.
If we slowed transportation and agricultural farming, greenhouse gases and carbon monoxide would be reduced magnificently.
3.
One way is that Humans are supplying demand for animal agriculture for food (when not need to). The greenhouse gases created by the factories alone are creating much of the ozone's destruction. Also, another reaction to demand of meat is, The space needed for farmland. They burn down much of the rainforest for farmland and grass for the cows and other animals. Thirdly, traveling alone and having many household luxuries aren't helping either. Lowering the use of composite resources and more wind, solar, and water energy can help the earth in total.
4.
Introducing invasive species endangers many of the other species. They could have a advantage or disadvantage over the other species. causing either over, or under, population for many of the species. Throwing the balance of it all off.
