<span>The fossil fuels form from the buried remains of ancient organisms, </span>formed from the remains of dead plants and animals.
<span> These plants and animals that have been converted to crude oil, coal, natural
gas, or heavy oils by exposure to heat and pressure in the earth's
crust over hundreds of millions of years. So, three things that act on decaying organisms to help form fossil fuels are:
-pressure
-heat
-physical and chemical changes
People use fossil fuels products for transportation and heating, many power plants burn coal for heat to turn turbines that generate electrical energy. ...</span>
Answer:
Therefore, 2 moles of oxygen will be required to oxidize 2.66 moles of oxygen. 72g of Aluminium will be completely oxidized by 44.8 lit of oxygen at STP.
Answer:
See explanation.
Explanation:
Hello!
In this case, we consider the questions:
a. Ideal gas at:
i. 273.15 K and 22.414 L.
ii. 500 K and 100 cm³.
b. Van der Waals gas at:
i. 273.15 K and 22.414 L.
ii. 500 K and 100 cm³.
Thus, we define the ideal gas equation and the van der Waals one as shown below:

Whereas b and a for hydrogen sulfide are 0.0434 L/mol and 4.484 L²*atm / mol² respectively, therefore, we proceed as follows:
a.
i. 273.15 K and 22.414 L.

ii. 500 K and 100 cm³ (0.1 L).

b.
i. 273.15 K and 22.414 L: in this case, v = 22.414 L / 1.00 mol = 22.414 L/mol

ii. 500 K and 100 cm³: in this case, v = 0.1 L / 1.00 mol = 0.100 L/mol

Whereas we can see a significant difference when the gas is at 500 K and occupy a volume of 0.100 L.

The mass number of hydrogen is 2
The mass number of helium is 4
The mass number of boron is 7
Cl (chloride) have negative charge Cl-, and it's called an anion bcz when an atom gains one or more electrons, a negative ion is formed, which makes the atom has more electrons than protons.
