Answer:

This is an oxidation-reduction (redox) reaction:

2 HI + 2 e- → 2 H0 (reduction)

Fe0 - 2 e- → FeII (oxidation)

HCl is an oxidizing agent, Fe is a reducing agent.

Given:

strojnjashka [21]

Answer:

≈ 708

Explanation

Here we have equation as:

4 Al + 3 O₂ → 2 Al₂O₃

As we know:

No of moles = Mass/ Molar mass

Here, Mass is 375 g and Molar mass is 27 gms, so no. of moles of Al will be:

=375 g /27 g/mol

= 13.889 mol

About mole ratio, we can see that for 4 moles of Al , 2 moles of Al2O3 are formed, so for 13.889 moles of Al, 13.889 mol ÷ 2 =6.944 moles of Al₂O₃ will be formed.

As we know:

Mass= No of moles/Molar mass

Mass of Al₂O₃ = 6.944 mol × 102 g/mol

= 708.288 g

Hope it helps!

What is the mass number of an ion with 107 electrons, 157 neutrons, and a 1 charge?

Oksi-84 [34.3K]

265
your answer would be 265. Because the charge of +1 means there is one more proton then electron. So, 108 protons plus 157 neutrons gives you your mass number of 265.
