<u>Answer:</u>
3.67 moles
<u>Step-by-step explanation:</u>
We need to find out the number of
moles present in 350 grams of a compound.
Molar mass of
= 24.305
Molar mass of
= 35.453
So, one mole of
= 24.305 + (35.453 * 2) = 95.211g
1 Mole in 1 molecule of
= 
Therefore, number of moles in 350 grams of compound = 0.0105 * 350
= 3.67 moles
The answer should be (4) they are negative subatomic particles and are found surrounding the nucleus. The nucleus is formed by neutrons and protons. Neutrons are neutral and protons are positive.
Answer:
Elements with unpaired valence electrons in the outer orbital are paramagnetic. Elements that are predicted to exhibit paramagnetic behavior may exhibit ferromagnetic behavior. Elements that contain only paired valence electrons are diamagnetic.
Answer:10.0 mL of 0.00500 M phosphoric acid
Explanation:
If we look at the Ka values of the acids, we will realize that phosphoric acid has a Ka of 7.1 * 10-3. It is the only acid in the list having acid dissociation constant less than 1. This means that it does not ionize easily in solution and a very large volume of base must be added to ensure that it reacts completely. Acids with Ka >1 are generally regarded as strong acids. All the acids listed have Ka>1 except phosphoric acid.
