Answer:

worldwide burning of fossil fuels

Explanation:

The heavy usage of the fossil fuels as energy sources for the industry has resulted in much increased emissions of CO2 in the atmosphere. It all started around 200 years ago with the Industrial Revolution. In order for the machines to function, efficient energy sources were needed, and the best thing at that time for that was the coal. Through the burning, the coal manages to release enormous amounts of CO2 into the atmosphere. After some time, the oil was discovered as well, and it started to be heavily used as well, further increasing the CO2 emissions. As the technology has been developing more and more, the demand for the usage of the fossil fuels has been increasing constantly, so there's an ever growing CO2 emissions into the atmosphere.

If 13.7 grams of manganese oxide reacts with excess hydrogen chloride gas, how many grams of water are formed?
Lerok [7]

Answer:

5.67 g OF WATER WILL BE FORMED WHEN 13.7 g OF MnO2 REACTS WITH HCl GAS.

Explanation:

EQUATION FOR THE REACTION

Mn02 + 4HCl --------> MnCl2 + Cl2 + 2H2O

From the balanced reaction between manganese oxide and hydrogen chloride gas;

1 mole of MnO2 reacts to form 2 mole of water

At STP, the molecular mass of the sample is equal to the mole of the substance. So therefore:

(55 + 16 * 2) g of MnO2 reacts to form 2 * ( 1 *2 + 16) g of water

(55 + 32) g of MnO2 reacts to form 2 * 18 g of water

87 g of MnO2 reacts to form 36 g of water

If 13.7 g of MnO2 were to be used?

87 g of MnO2 = 36 g of H2O

13.7 g of MnO2 = ( 13.7 * 36 / 87) g of water

= 493.2 / 87 g of water

Mass of water = 5.669 g of water

Approximately 5.67 g of water will be formed when 13.7 g of manganese oxide reacts with excess hydrogen chloride gas.

How many moles of silver chloride, produced from 100 g of silver nitrate reacting with barium chloride BaCl2?
Dmitrij [34]

Answer:

Equation of Reaction

2AgNO3 + BaCl2 === 2AgCl + Ba(NO3)2

Molar Mass of AgNO3 = 170g/mol

Moles of reacting AgNO3 = 100g/170gmol-¹

=0.588moles of AgNO3

From the equation of reaction...2moles of AgNO3 reacts to Produce 2Moles of Silver Chloride

So Their ratio is 2:2.

This means that 0.588Moles of AgCl Will be produced too.

ANSWER...0.588MOLES OF AgCl WILL BE PRODUCED.
