When you change the surface area of the reactants, we do increase the rate of the reaction. The surface of the reactant will have a higher chance to collide with a solid reactant. For example, atoms and molecules have to collide with each other.
I really hope I could help, sorry if I'm wrong! :)
Answer:
So they have the right answers
Explanation:
I know
The internal energy r<span>efers to the total energy of a system. The enrgies are kinetic energy and potential energy of the system that makes up the whole energies of the system.</span>
When 2 moles burn 6 moles of O2 is produced !
so for 16 moles , (6/2)×16= 48 moles will be produced !
so answer is A , 48 moles !
Answer:
=<em><u> 1.7 M</u></em>
Explanation:
Molecular mass of NaCl = ( 23+35.5 ) = 58.5g
58.5g of NaCl are weighed by 1 mole of NaCl
10.0g of NaCl will be weighed by ( 10÷58.5 )
<em> <u>= 0.17 moles of </u><u>NaCl</u></em>
100mL = ( 100÷1000)L = 0.1L
0.1L of a solution is occupied by 0.17 moles of NaCl
<u>1L</u> of solution will be occupied by [(1÷0.1)×0.17]
=<em><u>1</u></em><em><u>.</u></em><em><u>7</u></em><em><u> </u></em><em><u>M</u></em>
