lions [1.4K]

Answer:

Explanation:

Molar mass of KF= 39 + 19= 58g/mol

Mass of KF = 109g

Amount = mass/molar mass

Amount = 109/58

Amount = 1.9moles

Which statement best describes how photosynthesis follows the law of conservation of mass?
leva [86]

Answer:

O The number of oxygen atoms in the reactants used by this process equals the total number of oxygen atoms in the products.

Explanation:

The statement that best describes how photosynthesis follows the law of conservation of mass is that the number of oxygen atoms in the reactants used by this process is equal to the total number of oxygen atoms in the products.

 The equation of photosynthesis reaction is given as:

        6CO₂    +     6H₂O    →    C₆ H₁₂ O₆ +  6O₂

According to the law of conservation of mass, matter is neither created nor destroyed during the course of a chemical reaction.

By the virtue of this, the number of oxygen atom on both sides of the expression must be the same. Also, the number of carbon and hydrogen atoms must also be the same.

If a man has a mass of 83 kilograms on Earth, what will the force of gravity on his body be on the moon?
VladimirAG [237]
The answer is (A.) 135.6 N

————

Here is the formula you will need to answer the question.

Formula:
Force(N) = Mass(kg) x Acceleration(m/s²)
or... F(N) = m(kg) x a(m/s²)

————

We need to be certain of the information presented. The problem says the man has a "Mass" of 83 kilograms on Earth. If a man has a Mass of 83 kilograms on Earth, he has a mass of 83 kilograms everywhere. The mass for this problem (even on the moon) is 83.

Mass(kg): 83

————

To find the acceleration of object on other planets, moons, ect, you'll need to search the internet or ask a teacher. There are ways to calculate this, but the problem didn't supply the necessary information to do so.

Acceleration: 1.625 m/s²

————

Now just plug the information into the formula.

F(N) = m(kg) x a(m/s²)

N = 83 x 1.625
N= 135.875

When considering that there could be a slighty more accurate number for acceleration, it can be concluded that the best answer is (A.)

What is the strongest type of intermolecular force between solute and solvent in each solution?
Elenna [48]

Hydrogen bonding is the strongest type of intermolecular force between solute and solvent.

<h3>What is Intermolecular Force ?</h3>

Intermolecular force is also called secondary force is the force of attraction between molecules. It acts between ions and atoms.

<h3>What is Hydrogen Bonding ?</h3>

Hydrogen bond is the attractive forces which binds the hydrogen atom of 1 molecule with electronegative atom of other molecule.

CH₃OCH₃ form hydrogen bonding and H₂O can also form hydrogen bonding.

Thus from the above conclusion we can say that Hydrogen bonding is the strongest type of intermolecular force between solute and solvent.
