<u>Answer:</u> Mixture can be separated into its components but impure substance cannot be separated into components.
<u>Explanation:</u>
A mixture is defined as a combination of two or more different substances in which the component substances are individually distinct. The substances can be separated by physical processes. The separation dos not involve any chemical process because no new substance is being formed.
Impure substance is defined as a substance which can be mixture of elements, compounds or elements and compounds. The substances cannot be separated by physical means but can only be separated by chemical means.
Answer: The object's mass, height off the ground, and the strength of gravity :)
Answer:
591.25ml
Explanation:
4 cups=946ml
0.5cups=946÷8=118.25ml
2.5cups=118.25ml*5=591.25ml
I'll balance it for you :D
HNO3 + P → <span>H3PO4 + NO
break it down first (to see how many of each atom on each side) so
H- 1 H-3
N-1 N-1
O-3 O-12
P-1 P-3
now u gotta make the numbers equal on both sides
make the first H 3 so it's balanced with the other one by putting a 3 in front of it in the equation like this:
</span>3HNO3 + P → H3PO4 + NO
<span>
that changes the WHOLE equation except the P because it's not attached (so now the N is also 3 and the O as well)
</span>H- 3 H-3
N-3 N-1
O-9 O-12
P-1 P-3
so now the N is imbalanced on the product side, so do the same thing to fix it
3HNO3 + P → H3PO4 + 3NO
the O next to the N is now also 3 sooo
H- 3 H-3
N-3 N-3
O-9 O-15
P-1 P-3
3HNO3 + 3P → H3PO4 + 3NO
H- 3 H-3
N-3 N-3
O-9 O-15
P-3 P-3
3HNO3 + 3P → H3PO4 + 3NO
i realized halfway through this that the O is still unbalanced SOMEHOW
We can use any solution containing chloride ions as NaCl solution or even dilute HCl due to mercurous Hg₂²⁺ is from group I cations which precipitated as chloride while Sr²⁺ is from group V
Net ionic equation:
Hg₂²⁺ + 2 Cl⁻ → Hg₂Cl₂ (white precipitate)
while SrCl₂ is soluble salt<span />
