GalinKa [24]4 years ago

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.

11. Propane (C3Hg) is a fuel commonly used in gas grills.
Mrac [35]

Answer:

81.71%

Explanation:

One mole of propane contains 3 moles of carbon atoms and 8 moles of hydrogen atoms, as seen from the molecular formula of C_3H_8. In order to calculate the percent of carbon in propane by mass, we need to remember that %w/w (or percent mass) formula states that:

\omega=\frac{m_{component}}{m_{total}}\cdot100\%

That is, we need to divide the mass of the component of interest by the total mass of the compound and multiply by 100 to obtain the percentage.

For simplicity, let's take 1 mole of propane and find the mass of 1 mole (hence, we'll be finding the molar mass of propane). To do that, we add the 3 molar masses of carbon and 8 molar masses of hydrogen to obtain a total of:

M_{C_3H_8}=3M_C+8M_H=3\cdot12.011 \frac{g}{mol}+8\cdot1.00784\frac{g}{mol}=44.096 \frac{g}{mol}

Now that we have the molar mass of propane, we also need to find the total mass of carbon in 1 mole of propane. We know that we have a total of 3 moles of carbon which corresponds to:

M_C=3\cdot12.011 \frac{g}{mol}=36.033 \frac{g}{mol}

Dividing the mass of carbon present by the total mass of the compound will yield the mass percentage as defined by the formula we introduced:

\omega_C=\frac{36.033\frac{g}{mol}}{44.096 \frac{g}{mol}}\cdot 100\%=81.71\%

Difference between hard water and cold water ? ​
sweet-ann [11.9K]
The hardness of water is determined primarily by the amount of calcium and magnesium it contains. ... Instead of having higher levels of calcium and magnesium, soft water tends to have higher concentrations of sodium, or salt.

What are the products in the following chemical reaction?
hodyreva [135]

The products are on the right side of the chemical equation, while the reactants are on the left side of the chemical equation.

Therefore if we have:

methane + oxygen → carbon dioxide + water

Then the reactants are methane + oxygen

The products are: A) Carbon dioxide + Water
