If you were to measure the mass of magnesium and hydrochloric acid before combining them in the test tube, how would that mass c

SIZIF [17.4K]

The balanced chemical reaction for the system given is as follows:

2Mg + 2HCl = 2MgCl + H2

The mole ratio of the reactants is one is to one which means with a given amount of magnesium requires the same amount of hydrochloric acid to have a complete reaction. If supplied exactly, then after the reaction, all of the reactants are consumed and formed into the products.

Nitrogen and hydrogen combine at a high temperature, in the presence of a catalyst, to produce ammonia. N2(g)+3H2(g)⟶2NH3(g) Ass

yaroslaw [1]

Answer:

moles of ammonia produced = 0.28 moles

Explanation:

The reaction is

$N_{2}(g)+3H_{2}(g) --> 2NH_{3}(g)$

As per equation, one mole of nitrogen will react with three moles of hydrogen to give two moles of ammonia

So 0.140 moles of nitrogen will react with = 3 X 0.140 moles of Hydrogen

= 0.42 moles of hydrogen molecule.

this will give 2 X 0.140 moles of ammonia = 0.28 moles of ammonia

the moles of ammonia produced = 0.28 moles

Here the nitrogen is limiting reagent.

How many acidic H+ ion is given by H3BO3 in aqueous solution?? ...?

notka56 [123]

Boric acid, H3BO3, in aqueous solution would only give out one H+ ion. As it is also produce OH ion and by hydrolysis it produces one proton. All the boron compounds (BX3) are having only 6 valence electrons in it and should follow the octet rule by taking another electron.

B(OH)3 + 2 H2O → B(OH)4− + H3O
