Answer:
proton
Explanation:
The atoms is made from a nucleus and a electronic shell. The nucleus is composed from protons (positively charged) and neutrons (no charge). The electronic shell is defined by the presence of electrons (negativity charged).
Now a particular element is identified by the number of protons which have to be equal to the number of electrons in the electronic shell. A particular element may have the same number of protons but different number of neutrons, these are isotopes which have the same chemical properties.

Answer: 0.4578 g
Explanation:
Molarity of a solution is defined as the number of moles of solute dissolved per Liter of the solution.
where,
n= moles of solute
= volume of solution in ml = 25.0 ml
Thus 0.4578 g of nickel(II) nitrate is to be dissolved in 25.0 mL of 0.100 M solution.
Answer:
definately substance A beacause its the lowest ph leval which means its more acidic
Explanation:
Answer:
B
Explanation:
If you remeber a balloon in hot air, it pops. This is because the molecules are moving too fast and need more space to move, thus popping the balloon. If you put a balloon in cold air, then it shrinks, the molecules not moving fast enough and don't need as much space.
