Chemistry

Firlakuza [10]3 years ago

Electrons are negatively charged particles while protons that are found in the nucleus are positively charged. In the natural scheme of things, positive and negative charge produces an attractive force that pulls one particle towards the other. However, based on Rutherford's model of an atom, which is the planetary model that conclusively suggests that electrons revolve around the nucleus, such attraction between the two opposing particles creates an electromagnetic force that enables electrons to move around the positive nucleus thus preventing the electrons from spiraling towards it.

How many moles of hydrogen are in the sample?<br> Round your answer to 4 significant digits.
finlep [7]

Answer:

1.56 mol H₂

Explanation:

Mg₃(Si₂O₅)₂(OH)₂

<em>There are 4 Si moles per Mg₃(Si₂O₅)₂(OH)₂ mol</em>. With that in mind we can <u>calculate how many Mg₃(Si₂O₅)₂(OH)₂ moles are there in the sample</u>, using the <em>given number of silicon moles</em>:

  • 3.120 mol Si * \frac{1molMg_3(Si_2O_5)_2(OH)_2}{4molSi} = 0.78 mol Mg₃(Si₂O₅)₂(OH)₂

Then we can <u>convert Mg₃(Si₂O₅)₂(OH)₂ moles into hydrogen moles</u>, keeping in mind that <em>there are 2 hydrogen moles per Mg₃(Si₂O₅)₂(OH)₂ mol</em>:

  • 0.78 mol Mg₃(Si₂O₅)₂(OH)₂ * 2 = 1.56 mol H₂
