In an unsaturated solution, the amount of solute is less than required in the solution. So, it can dissolve more solute.

Solid state is more dense than the liquid state as the molecules are closely packed in a solid.

Density is temperature dependent as with increase in temperature volume increases. So, the density decreases.

Like dissolves like. A polar solute will dissolve in a polar solvent.

So, the correct statement among the given options is B.For most substances, the solid state is more dense than the liquid state.

The answer is B.) For most substances, the solids state is more dense than the liquid state.

A. false because unsaturated solutions will dissolve more solute.
B. true.
C. false because according to the last question, density is dependent on temp.
D. false because likes dissolve likes: polar dissolves in polar, nonpolar dissolves in non polar.i hope this helps.=^b

Calcium hypochlorite, Ca(OCl)2, is a bleaching agent produced from sodium hydroxide, calcium hydroxide, and chlorine. Socium chl
bija089 [108]

Answer:  The missing coefficient is 2.

Explanation:

According to the law of conservation of mass, mass can neither be created nor be destroyed. Thus the mass of products has to be equal to the mass of reactants. The number of atoms of each element has to be same on reactant and product side. Thus chemical equations are balanced.

2NaOH+Ca(OH)_2+2Cl_2\rightarrow Ca(OCl)_2+2NaCl+2H_2O

As in the products, there are 2 atoms of sodium, thus there will be 2 atoms of  of sodium in the reactant as well.  This will balance the number of hydrogen and oxygen atoms as well.

Thus the missing coefficient is 2.

What is the speed of a bobsled whose distance-time graph indicates that it traveled 112m in 29s?
nordsb [41]
Well to find speed you have to do distance /time. So, in this case you do 112m /29s which it will be 3.862 which if you round it, it will be 3.86 m/s
