88 g of the strontium reacts with 160 g bromine to produce how many strontium bromide

Chemistry

Mass of strontium = 88 g

Atomic mass of Sr = 87.62 u

Moles = mass /atomic mass

Moles of Sr =  88 / 87.62 = 1.004

Mass of bromine = 160 g

Atomic mass of Br = 79.904 u

Molar mass of Br₂ = 79.904 x 2 = 159.808 g/mol

Moles = mass /molar mass

Moles of Br₂ =  160 / 159.808 = 1.001

The balanced chemical equation of the reaction between strontium and bromine:

Sr(s) + Br₂(l) = SrBr₂

The molar ratio between Br₂  and SrBr₂ is 1:1

So the moles of SrBr₂ produced from 1.001 moles of Br₂ is 1.001.

Moles = mass /molar mass

Mass = moles x molar mass

Molar mass of SrBr₂ = 247.4280 g/mol

Mass = 1.001 mol x 247.4280 g/mol

Mass = 247.428 g

The mass of strontium bromide produced is 247.428 g.

Predict the products of the following reaction: <br> RbNO2 +BaCO3-&gt;
sukhopar [10]

Answer:

2RbNO2 + BaCO3 → Rb2CO3 + Ba(NO2)2

Explanation:

The balanced reaction equation is shown below;

2RbNO2 + BaCO3 → Rb2CO3 + Ba(NO2)2

This reaction is possible because the reduction potential of Rb is -2.98V while that of Ba is –2.92 V. Hence Rb can displace Ba from its salt solution.

The equation is balanced since the number of atoms of each element on the left and right hand sides of the reaction equation are equal.

Monica [59]

Answer:

1.239 * 10^8 Kg

Explanation:

Since all the electricity consumed comes from natural gas;

amount of electricity consumed = 700 * 300,000 = 2.1 * 10^8 kWh

So, amount of CO2 consumed is given by;

amount of electricity consumed * amount of CO2 per kWh

Hence,

Amount of CO2 = 2.1 * 10^8 kWh * 0.59 = 1.239 * 10^8 Kg
