7 0

Answer:

2 moles of Substance B

Explanation:

Because 1 mole of any substance contains 6.02× 10²³ particles either atoms, molecules, ions or even electron(Avogardo Constant)

Therefore 12.04 × 10²³/ 6.02× 10²³  =  2 mole of Substance B

How would a fast-flowing river be most likely to move sand-sized particles of sediment?
Nitella [24]
A fast-flowing river would most likely be to move the skaters glide around the rink b<span>y lifting it up and carrying it downstream. In a fast-flowing river, the pressure is strong, which makes it easier for sand-sized particles of sediments to be carried or transferred. Hope this answer helps.</span>

A student has a mass of 90 kg what would his weight be on mars if the acceleration due to gravity is 3.7 ?
Mumz [18]

Answer:

333N

Explanation:

Once we have the object's mass, we can find the weight by multiplying it by the gravitational force, which it is subject to. Being that Mars has a gravitational force of 3.7m/s2, we multiply the object's mass by this quantity to calculate an object's weight on mars.

So an object or person on Mars would weigh 37.83% its weight on earth. Therefore, a person would be much lighter on mars. Conversely, a person is 62.17% heavier on earth than on Mars.

Nitrogen and hydrogen combine to form ammonia.
zhenek [66]

The balanced chemical equation for the formation ammonia is

    N2(g) + 3H2(g)  ----> 2NH3(g)  .        

The balanced chemical equations explains that the same number of each element exist as reactants and products.  The coefficients in a balanced equation must be the simplest whole number ratio. Mass is always conserved in chemical reactions.

For the formation of ammonia, the chemical equation is

     N2(g) + H2(g)  ----> NH3(g)

Balancing the chemical reaction, we can write,

  N2(g) + 3H2(g)  ----> 2NH3(g)  .  

This equation shows two nitrogen entering the reaction together and two hydrogens entering the reaction together. Since NH3 is multiplied by a coefficient of 2 there are now 2 nitrogen and 6 hydrogens. The 6 hydrogens come from the 2 multiplied by the subscript of 3. This is the balanced chemical reaction.
