Find mass of 3 moles of water

EleoNora [17]

Answer:

54 g

Explanation:

1 mole of water = H2O

mass of 1 mole of H2O= mass of h2 + mass of o

= 2× mass of h +mass of o

= 2×1+16 =18 g

1 mole of water = 18g

3moles of water = 18×3g= 54g

What type of bond will form between two chlorine atoms?

Trava [24]

Since both atoms are the same and are both nonmetals, they would form a Nonpolar covalent bond. This bond occurs when usually atoms of the same element or atoms of propriety electronegativity differences are sharing electrons to form bonds. There is an equal sharing of valence electrons in this chemical bond.

What would happen if N2 were added to N2(g) + O2(g) = 2NO(9) at

DerKrebs [107]

Balanced chemical equation is :

$N_2(g)+O_2(g)-->2NO(g)$

It is given that the equation is in equilibrium.

We need to find what will happen if we add more $N_2$ is added .

By Le Chatelier's principle :

Changing the concentration of a chemical will shift the equilibrium to the side that would counter that change in concentration.

It means production of the side where content is added will decrease and concentration on other side will increase .

So , more NO would form .

Therefore, option B. is correct.

Hence, this is the required solution.

aalyn [17]

Answer: Value of impulse is $2.4\times 10^3\text{kg m/s}$

Explanation: lmpulse is defined as the amount of force acting over a short time interval 't' which is equal to the change in momentum of the body having mass 'm'.

Mathematically,

$J=F\times t=m\Delta v$
