A gas mixture contains the following gases with the mole fractions indicated:
water (0.164), hydrogen (0.278), oxygen (0.455), and carbon dioxide (0.101). The
mixture also contains carbon monoxide. What is the mole fraction of carbon
monoxide? PLEASE HELP!
Hi there!
To find the mole fraction for the remaining compound (Carbon monoxide), we must remember that mole fractions add up to ONE.
We can subtract the mole fractions of all of the other gases from one to solve for the mole fraction of carbon monoxide.
1 - 0.164 - 0.278 - 0.455 - 0.101 = 0.002

Which substance is known as the universal solvent because it dissolves more solutes than any other solvent?.
Answer:
Water(H20)
Explanation:
Water is called the universal solvent because more substances dissolve in water than in any other chemical. This has to do with the polarity of each water molecule. The hydrogen side of each water (H2O) molecule carries a slight positive electric charge, while the oxygen side carries a slight negative electric charge.

What causes “gaps in the rock record” and how is that described?
Answer:
An unconformity is a widespread surface separating rocks above and below, which represents a gap in the rock record. Unconformities occur when either erosion wears away rocks, or rock deposits never form. Therefore, a time gap exists between when the rocks below the unconformity formed and when those above it formed.

What is the molarity of a solution formed when you add 200. Ml of water to 50. Ml of 5. 0 m hcl
The molarity of a solution formed when you add 200 mL of water to 50 mL of 5. 0 M HCl is 1.25M.
How to calculate molarity?The molarity of a solution can be calculated using the following formula:
M1V1 = M2V2
Where;
M1 = molarity of a baseM2 = molarity of acidV1 = volume of baseV2 = volume of acidM1 × 200 = 50 × 5
200M1 = 250
M1 = 250/200

B.) Activation energy minus energy of the products will be greater than activation energy minus energy of reactants.
C.) Activation energy minus energy of the products will be less than activation energy minus energy of reactants.
D.) Activation energy will be less than the energy of the products.
Activation energy will be less than the energy of the products in an exothermic reaction. Therefore, option (D) is correct.
What is exothermic reaction?In this type of reaction, the energy of the products is lower than the energy of the reactants. As a result, the difference in energy is released as heat or light, which can be detected by measuring the temperature or observing the light emitted during the reaction.
Exothermic reactions occur spontaneously, meaning they do not require an external energy source to start the reaction. Common examples of exothermic reactions include combustion, oxidation, and neutralization. These reactions often involve the formation of stronger bonds between atoms or molecules, which releases energy in the form of heat or light.
Exothermic reactions play an important role in many natural and industrial processes, including respiration, photosynthesis, and the production of electricity in power plants.
