Rain bc it’s hot then cools
Answer:
See below!
Explanation:
A. The picture of the graph is attached. You can tell the amount of protons in an element by looking at the periodic table. The elements are ordered by the number of protons in an element.
B. Carbon and silicon are at the peaks of the chart. The peak is the highest point in a graph.
C. The elements belong to the non-metal group.
D. The halogens are non-metals, and their vapors are colorless.
The halogens are toxic to humans.
Halogen molecules are made of two atoms; they are diatomic.
Halogens react with non-metals to form crystalline compounds that are salts.
The halogens get less reactive going down the group on the periodic table.
Halogens can bleach vegetable dyes and kill bacteria.
E. The picture of the table is attached. To figure which numbers to put where, you need to pay attention to the other numbers. The halogens follow a trend with each of these properties. You have to put in the numbers that fit in among the other numbers.
Answer:
Boiling is 212* Freezing is 32*

It simple facts
Answer:
52.45g
Explanation:
The computation of the mass of pure acetic acid in 125mL of this solution is shown below:
The percentage of mass would be equivalent to the g of solute in each 100g of water
As we know that
density = mass ÷ volume
So,
Volume = mass ÷ density
V = 100g / 1.049 (g / ml)
V = 95.328 mL
Now In every 95,328 ml of C_2H_4O_2 there are 40g of C_2H_4O_2
i.e.
each 125ml of C_2H_4O_2 there are 52.45g
SO,
x = 40g. 125ml ÷ 95.328
x = 52.45g
