<span>I think the correct
answer is 109.5 degrees. The bond angle of a chlorite ion or ClO2- ion is 109.5
and has a bent shape. This is because of two groups of bonding electrons and
two lone pairs of electrons. Another example of a molecule that has a bent
molecular geometry is water. It results from its tetrahedral electron pair
shape.</span>
Answer:
p=m/v
m=mass:402g
v=volume:385ml
p=density:?
divide 402 by 385 to get 1.04 the density is 1.04ml
Density (p)= mass (g)/volume (ml)
HCl and NaOH react based on the following equation:
HCl + NaOH ..............> NaCl + H2O
This reaction is known as a double replacement reaction. In this types of reactions, the electrolyte (and the solvent) is water and the driving force is mainly the formation of a non-electrolyte produce.
Based on this, the driving force in the above neutralization reaction is the formation if the non-electrolyte salt (NaCl)
First you need to know the molecular weight of sugar (C6H12O6) which is 180.156g/mol
You have half a mole so you have 90.078g
If you wanted to make 1L of a 1.2M solution of glucose you would need 180.156*1.2=216.1872g
But you only have 90.078g
So you need to figure out how much this 90.078g will make if the solution must be 1.2M:
90.078g/216.1872g=xL/1L
solve for the X and you get 0.416666666...
so 416.7ml or 0.417L
