Answer:
Approximately 206 grams.
Explanation:
How many moles of sulfuric acid 
are there in this solution?
.
The unit for concentration "
" is equivalent to mole per liter. In other words, 
. For this solution, the concentration of is 
.
.
What's the mass of that 
of ?
Start by finding the molar mass 
of .
Relative atomic mass data from a modern periodic table:
- H: 1.008;
- S: 32.06;
- O: 15.999.
.
.
.
In other words, the chemist shall need approximately 206 grams of to make this solution. As a side note, keep in mind that the 206 grams of also take up considerable amount of space. Therefore it will take less than 5.00 L of water to make the 5.00 L solution.

and i don't know about the last one
Answer:
The substances in a mixture can be separated using physical methods such as filtration, freezing, and distillation.
There is little, see Enthalpy of mixing, or no energy change when a mixture forms.
Mixtures have variable compositions, while compounds have a fixed, definite formula.
Explanation:
Atoms are made of 3 types of subatomic particles ; protons, neutrons and electrons
protons and neutrons are located inside the nucleus and electrons are found in energy shells around the nucleus. Protons are positively charged, electrons are negatively charged and neutrons are neutral. elements in their ground state are neutral with equal amounts of protons and electrons.
Atomic number is the number of protons. atomic number is characteristic for the element.
atomic number of Be is 4 therefore Be has 4 protons
answer is B. 4
