Answer:
A mole ratio is the ratio between the amounts in moles of any two compounds involved in a chemical reaction. ... The mole ratio may be determined by examining the coefficients in front of formulas in a balanced chemical equation. Also known as: The mole ratio is also called the mole-to-mole ratio.
Answer: 75.7 % yield
Explanation:
The balanced chemical equation is:
According to stoichiometry :
68.2 g of will require = 64 g of
Thus 7.5 g of will require = of
Thus is the limiting reagent as it limits the formation of product and is the excess reagent.
As 68.2 g of give = 96 g of
Thus 7.5 g of give = of
% yield=
Thus 75.7 % yield is there.
Other molecules monitored along with LDL and HDL in a patient's blood include triglycerides, low density lipoproteins, and high density lipoproteins.
Answer:
ExplanatioHydrogen cannot exist in free state as hydrogen needs an electron to attain stability. If an element does not attain stability it cannot exist on its own. In Sun there are large number hydrogen atoms and helium atoms present this creates a lot of energy and nuclear fusions are occured. Gases that attain stability can normally exist on their own. E.g. Argon, Neon, Helium, Krypton and Xenon. Gases that cannot exist on their own are:
H2
O2
N2

In order to calculate the final volume of the gas, we may apply Charles Law, which states that for a fixed amount of gas subject to a fixed amount of pressure, the volume and temperature of a gas are directly proportional. This is:
V/T = constant
Using this equation,
5/298 = V/278
V = 4.66 L
The final volume of the gas is 4.66 liters
