The total question is not found here but the onion structures that we can see with 30 X are the cell wall and an important vacuole.
<h3>What is 30X magnification?</h3>
The 30X magnification does not exist, nowadays the current objective lens comes in 20X, and 40X.
Using this magnification, we might see plant cells that divide to produce cell walls between daughter cells after a process called mitosis.
In conclusion, the total question is not found here but the onion structures that we can see with 30 X are the cell wall and an important vacuole.

Answer: Small molecular structure
Explanation:
> Bromine and Hydrogen are both non-metals, so they hence cannot form ionic compounds and metals. As such, Ionic Lattice and Metallic structure is wrong.
> gaseous Hydrogen Bromide HBr is produced. Giant covalent substances, such as diamond, have very high melting and boiling points. As such, HBr is a small molecular structure, or a simple covalent substance.
They turn blue litmus paper to red.
They also taste sour.
Answer:
2 Na + 1 Cl2 -> 2 NaCl
Explanation:
The answer is really simple, because if you have 1 nonmetal element that has a subscript of 2, you need to multiply the product and the first reactant by 2 to balance it.
Answer:
Option E is the correct one
Explanation:
K₂Cr₂O₇ → Potassium dichromate
A ionic salt which its molar mass is 294.18 g/m
It is composed by 2 mol of K, 2 mol of Cr and 7 mol of O
2 mol of K = 78.2 g
2 mol of Cr = 104 g
7 mol of O = 112 g
In 294.2 g of compound we have __78.2 g K __ 104 g Cr ___ 112 g O
Let's calculate the percent
(78.2 / 294.2) .100 = 26.59% K
(104 / 294.2) .100 = 35.35% Cr
(112 / 294.2) . 100 = 38.06 % O
