Answer:
950 torr
Explanation:
Step 1: Given data
- Initial volume of the gas (V₁): 1.00 L
- Initial pressure of the gas (P₁): 760 torr
- Final volume of the gas (V₂): 0.800 L
- Final pressure of the gas (P₂): ?
Step 2: Calculate the final pressure of the gas
If we assume ideal behavior and constant temperature, we can calculate the final pressure of the gas using Boyle's law.
P₁ × V₁ = P₂ × V₂
P₂ = P₁ × V₁/V₂
P₂ = 760 torr × 1.00 L/0.800 L = 950 torr
Answer:
When fossil fuels are bumed they release toxic gases into the air that cause pollution and increase global warming
Explanation:
Fossil fuels are fuels which were formed from the remains of dead plants and animals buried underground for millions of years ago, which anaerobic bacteria and the high pressure and heat underground transformed into the fuels as we know them today. Fossil fuels are mainly hydrocarbons and they include coal, petroleum, natural gas, oil shales, bitumens, tar sands, and heavy oils.
The combustion of fossils fuels today provides the majority of the energy used by man worldwide. Energy from fossil fuels power our homes and industries, cars, trains aeroplanes, etc.
However, the combustion of fossil fuels impacts the environment negatively. Fossil fuels produce carbon dioxide as end-products when burnt which pollutes the airanspd is a major greenhouse gas contributing to global warming.
Combustion of fossil fuels releases acidic gases such as sulfur dioxide, nitrogen dioxide to the environment resulting in acid rains as well as many unpredictable and negative changes in the environment.
Molarity = Moles/Liters. First, convert all ml to Liters by moving the decimal 3 places to the left and then calculate:
.001 L HCl x 6M/L HCl /.5 Liters of solution=0.012 Moles per Liter aka molarity
In many cases, elements that belong to the same group (vertical column) on the periodic table form ions with the same charge because they have the same number of valence electrons.
