The molarity of a solution equals to the mole number of the solute/the volume of the solution. For NH4Br, we know that the mole mass is 98. So the molarity is (14/98) mol /0.15 L=0.95 mol/L.
Answer:An atom
Explanation:
Because molecules more spread out and have things that connnect them and are not bunched up togoether
And Atoms are all packed up like in the picture
Hope this helps!:D
Answer:
The minimum amount of energy needed the the cell to perform various cellular,biochemical and physiological activities is known is Gibbs free energy.
Explanation:
The change in gibbs free energy of is very much important to determine whether a given reaction is spontaneous,non spontaneous or equilibrium.
1 If gibbs free energy change of a reaction is negative then the reaction is spontaneous.
2 If the free energy change is 0 then the reaction is in equilibrium stage.
3 If free energy change is positive then the reaction is non spontaneous.
Answer:
6
Explanation:
The given reaction is aluminium with hydrochloric acid
2Al + 6HCl → 2AlCl3 + 3H2
the product is aluminium chloride and hydrogen gas.
We can clearly, calculate that there are 2*3=6 chlorine atoms in product side of the reaction.
