Answer: A. one atom
Explanation: i did some research on it and that is what i found.
<em>This statement is false.</em> When you say full octet, it means that an element opts to have eight electrons in its valence shell to become stable. However, since a hydrogen atom only has 1 electron when neutral, it is impossible to reach a full octet. That is why Hydrogen is one of the exceptions to this octet rule.
Here, Equation: 2NaOH + H₂SO₄ → Na₂SO₄ + 2H₂O
We know, Concentration (c) = Number of moles(n) / Volume (v)
Substitute the given values,
0.02 = n / 0.3 [ 300 mL = 0.3 L ]
n = 0.3 * 0.02
n = 0.006
Now, According to stoichiometry, There is 1 Molecule of Sodium sulfate produces for every 2 molecules of NaOH.
So, Number of Moles of Na₂SO₄ = 0.006/2 = 0.003
Given mass = Molar mass * Number of moles
M = 142.04 * 0.003
M = 0.426 g
In short, Your Answer would be: 0.426 g
Hope this helps!

Answer:The main job of the innate immune system is to fight harmful substances and germs that enter the body, for instance through the skin or digestive system. The adaptive (specific) immune system makes antibodies and uses them to specifically fight certain germs that the body has previously come into contact with.
