Law of Definite Proportions states that a compound is composed of the same ratio of elements present. The formation of water has a reaction:

H2 + 1/2 O2 = H2O

The limiting reactant would be the element with the least ratio of molar mass to stoichiometric coefficient, and that would be H2, not O2.

Answer:  

Explanation:  Law of Definite Proportions state that in a chemical compound, the constituent element will always exist in a fixed ratio which does not depend on the source of preparation.

So when hydrogen is burned in oxygen to form water, the composition of water formed does not depend on the oxygen but it depends on the hydrogen itself.

H_{2}O + 1/2 O_{2} \rightarrow H_{2}O

Thus the reaction usually depends on the limiting reagent ad hence , in the above reaction, hydrogen is the limiting reagent. Thus the reaction will depend on the hydrogen, not on oxygen.

Calculate the percentage of water of crystallisation in MgSO⁴ 7H²O
Bas_tet [7]

Answer:

Formula of EPSOM salt = MgSO4.7H2O

molecular mass of MgSO4.7H2O = atomic mass of Mg + atomic mass of S + 4 × atomic mass of O + 7 { 2 × atomic mass of H + atomic mass of O }

= 24 + 32 + 4× 16 + 7{ 2 × 1 + 16 } g/mol

= (24 + 32 + 64+ 126 ) g/mol

= 246 g/mol

molecular mass of total water = 7 × ( 2× atomic mass of H + atomic mass of O )

= 7 × 18 = 126 g/mol

now ,

% mass of H2O in EPSOM salt = {total molar mass of H2O/molar mass of Epsom salts }× 100

= {126/246 } × 100

= 12600/246

= 51.21 %

Hello!

First you need to calculate q 
<span>delta U is change in internal energy </span>

<span>delta U = q + w </span>
<span>q is heat and w work done </span>
<span>here work was done by the system means energy leaving the system so w is negative </span>

<span>delta U = q + w </span>

<span>q = delta U - w = 6865 J - (-346 J) = 7211 J = 7.211 KJ </span>

<span>q = m x c x delta T </span>

<span>7211 J = 80.0 g x c x (225-25) °C </span>

<span>c = 0.451 J /g °C
</span>
Hope this Helps! Have A Wonderful Day! :)

What is smaller than one cell
mr_godi [17]
The organelles and substances inside the organelles are smaller. On a molecular level a group that are smaller are hadrons, which are the group of particles that consist of protons and neutrons. Even smaller than hadrons are leptons, which consist of neutrinos, electons, and MANY others.
