The solubility of CaCl2 in water is 25g per 50 mL of H2O. How many grams of CaCl2 will dissolved to form a saturated solution in

Natasha2012 [34]

Answer: option B. 5g

Explanation:

50mL of H2O dissolves 25g of CaCl2.

Therefore, 10mL of H2O will dissolve Xg of CaCl2 i.e

Xg of CaCl2 = (10 x 25) /50 = 5g

What is the molarity of 10.0 g of NaCl dissolved in water to make 100. mL?

tigry1 [53]

Answer:

= 1.7 M

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 )

 = 0.17 moles of NaCl

100mL = ( 100÷1000)L = 0.1L

0.1L of a solution is occupied by 0.17 moles of NaCl

1L of solution will be occupied by [(1÷0.1)×0.17]

=1.7 M

Describe the motion of molecules in these two

Ilya [14]

Answer:

When in direct contact, the fast-moving molecules in the radiator collide with the slow-moving molecules in the ice cube. Kinetic energy is transferred from the molecules in the radiator to the molecules in the ice cube, causing a slowdown of the radiator molecules and an acceleration of the ice molecules.

KClO3 --->KCl+3/2O2 assign oxidation states to each element on each side of the equation.(reactants and produc? KClO3 --->

marusya05 [52]

K will always have an oxidation state of +1. Now O is -2 except in peroxides, this is not a peroxide, so total charge will be -6, if you subtract the +1 of K from it, it leaves -5 charge to be neutralized by Cl in KClO3, so Cl will be +5. In the product side, K will still have the same oxdiation which is +1 and Cl would have -1. O2 will have zero. Now, Cl is gaining the electrons to go from +5 to -1, so it is getting reduced while O2 is losing electrons to go from -2 to zero so it is getting oxidized.
