In the reaction 3H2 + N2 → ____ NH3, what coefficient should be placed in front of NH3 to balance the reaction?

zubka84 [21]

2. 3H2 + N2 means you have 6 Hs and 2 Ns. NH3 has one N and 3 Hs, so you need 2 NH3s in order to have the 2 and 6 of each that you need on both sides of the reaction.

A metal oxide with the formula mo contains 15.44% oxygen. in the box below, type the symbol for the element represented by m.

lana66690 [7]

<u>Answer:</u> The element represented by M is Strontium.

<u>Explanation:</u>

Let us consider the molar mass of metal be 'x'.

The molar mass of MO will be = Molar mass of oxygen + Molar mass of metal = (16 + x)g/mol

It is given in the question that 15.44% of oxygen is present in metal oxide. So, the equation becomes:

$\frac{15.44}{100}\times (x+16)=16g/mol\\\\(x+16)=\frac{16g/mol\times 100}{15.44}\\\\x=(103.626-16)g/mol\\\\x=87.62g/mol$

The metal atom having molar mass as 87.62/mol is Strontium.

Hence, the element represented by M is Strontium.
