Answer:
<h2>0.52 g/mL</h2>
Explanation:
The density of a substance can be found by using the formula
From the question
volume = final volume of water - initial volume of water
volume = 35 - 8 = 27 mL
We have
We have the final answer as
<h3>0.52 g/mL</h3>
Hope this helps you
Answer:
Explanation:
We know we will need an equation with masses and molar masses, so let’s gather all the information in one place.
M_r: 261.34 233.39
Ba(NO₃)₂ + Na₂SO₄ ⟶ BaSO₄ + 2NaNO₃
m/g: 75.00
1. Moles of Ba(NO₃)₂
2. Moles of BaSO₄
The molar ratio is (1 mol BaSO₄/1 mol Ba(NO₃)₂
3. Mass of BaSO₄
Both the atoms are of the same element but one of them is electrically neutral and the other has a stable electronic configuration.
<h3>What is the meaning of a neutral atom?</h3>
An atom is said to be neutral because it has an equal number of electrons and protons in it.
If two different atoms have nine protons each and the same mass but one is neutral while the other has a negative charge.
This implies both the atoms have the same nucleus but different charges so it can be concluded that they are both the atoms of the same element but one of them is electrically neutral and the other has gain electron from other element and have stable electronic configuration.
