Carbon dioxide is a nonpolar molecule true of false

Chemistry
1 answer:
denis-greek [22]3 years ago
7 0
This statement is TRUE.

The polarity of the molecule is caused by unequal sharing of the electrons in the covalent bond. Even though the carbon dioxide molecule is made from two different atoms, two oxygen atoms and one carbon atom, the CO2 molecule is non polar because of the structure of the molecule.
The CO2 has a linear, symmetrical structure. This means that the two oxygen atoms with greater electronegativity are symmetrically placed around the carbon molecule. This arrangement of atoms causes a balance in the sharing of the electrons, making the molecule non polar.

-You wish to make a 0.203 M hydrochloric acid solution from a stock solution of 6.00 M hydrochloric acid. How much concentrated
lubasha [3.4K]

For all three questions, we will use the fact that

  • molarity = (moles of solute)/(liters of solution)

1) For 175 mL of solution at 0.203 M, this means that:

  • 0.203 = (moles of solute)/0.175
  • moles of solute = 0.035523 mol

Considering the hydrochloric acid solution, if we have 0.035523 mol, then:

  • 6.00 = 0.035523/(liters of solution)
  • liters of solution = 0.035523/6.00 = 0.0059205 = <u>5.92 mL (to 3 sf)</u>

<u />

2) If there is 20.3 mL = 0.0203 L, then:

  • 8.20 = (moles of solute)/0.0203
  • moles of solute = 0.16646 mol

This means that the molarity of the diluted solution is:

  • 0.16646/(0.200) = <u>0.832 M (to 3 sf)</u>

<u />

3) If we need 1.50 L of 0.700 M solution, then:

  • 0.700 = (moles of solute)/1.50
  • moles of solute = 1.05 mol

Considering the 9.36 M acid solution, from which we need 1.05 mol of perchloric acid from,

  • 9.36 = 1.05/(liters of solution)
  • liters of solution = 1.05/9.36, which is 0.11217948717949 L, or <u>112 mL (to 3 sf)</u>

Help me please !! How to solve it ??
snow_tiger [21]
1st one= CaO +H2O=Ca(OH)2
product side-
Ca=1
O=2
H=2
Reactant side-
Ca=1
O=2
H=2
The first one is balanced for you 
There is 1 calcium on each side 2 oxygens on each side and 2 hydrogens on each side
