The mass is simply the product of volume and density. But
first, let us convert the volume into cm^3 (cm^3 = mL):
volume = 2.5 cups * (240 mL/cup)
volume = 600 mL = 600cm^3
So the mass is:
mass = 600 cm^3 * (1 g / cm^3)
<span>mass = 600g</span>
B. carbon sequestration
Explanation:
Carbon sequestration is a method that reduces carbon dioxide emissions by storing them for a long time.
- It is long term harvesting or sequestering of carbon dioxide from the atmosphere in order to avert air pollution and climatic change problems.
- Carbon sequestration is usually employed in the storage and capture of atmospheric carbon dioxide.
- The carbon dioxide can be sequestered using biologic or geologic means.
- Carbon dioxide gas is used to enhance oil recovery from geologic formations that have low permeability or those with low formation pressure to push out the oil.

Answer:
d. IF3
Explanation:
The Octet rule posits that atoms gain, atom lose, or share electrons in order to have a full valence shell of 8 electrons. This statement occurs when atoms also combine to form molecules until they attain or share eight valence electrons either by losing or gaining eletrons.
From the given options, a valid Lewis structure that cannot be drawn without violating the octet rule is IF3
Answer:
The volume of the gas is determined, which will allow you to calculate the temperature.
Explanation:
According to Charles law; the volume of a given mass of an ideal gas is directly proportional to its temperature at constant pressure.
This implies that, when the volume of an ideal gas is measured at constant pressure, the temperature of the ideal gas can be calculated from it according to Charles law.
Hence in the Ideal Gas Law lab, the temperature of an ideal gas is measured by determining the volume of the ideal gas.
Answer:
10.1g of H₂ are produced
Explanation:
To solve this question we need, first, to convert the mass of each reactant to moles and, using the chemical reaction, find limiting reactant. With limiting reactant we can find the moles of H2 and its mass:
<em>Moles Zn -Molar mass: 65.38g/mol-:</em>
307g * (1mol / 65.38g) = 4.696 moles
<em>Moles HCl -Molar mass: 36.46g/mol-:</em>
381g HCl * (1mol / 36.46g) = 10.45 moles
For a complete reaction of 10.45 moles of HCl are required:
10.45 moles HCl * (1mol Zn / 2mol HCl) = 5.22 moles Zn
As there are 4.696 moles of Zn, <em>Zn is the limiting reactant</em>
<em />
The moles of H₂ produced = Moles of Zn added = 4.696 moles. The mass is-Molar mass H₂ = 2.16g/mol-:
4.696 moles * (2.16g / mol) =
<h3>10.1g of H₂ are produced</h3>
