Water ionizes because: Select one: The smaller electronegative oxygen atom strips the electron from one of its hydrogen atoms, l

Ivahew [28]

Answer:

The larger electronegative oxygen atom strips the electron from one of its hydrogen atoms, leaving the proton to dissociate.

Explanation:

Water is a molecule composed of hydrogen and oxygen atoms that forms a covalent bond i.e. share electrons. However, due to the fact that the oxygen atom in a water molecule is more electronegative than the hydrogen molecule, it tends to draw electrons towards itself, leaving the hydrogen atom more positive. This causes the POLARITY of water.

To ionize means for the atoms of a compound to dissociate into electrically charged ions (positive and negative) in an aqeous solution. Water is able to ionize because the more electronegative oxygen atom draws the electron from one of its hydrogen atoms, leaving the proton (H+) to dissociate.

Does his model correctly show why the properties of the ending substances are different from the properties of the starting subs

topjm [15]

Answer:

Samira's model is incorrect because not all atoms are accounted for

Explanation:

The image of Samira's model has been attached to this answer to enhance the explanation.

What is depicted in that model is rightly regarded as a chemical change. In a chemical change atoms of substances are rearranged as new substances are formed.

However, all atoms in the products must also be found in at least one of the reactants. In this case we have an atom in one of the products that is not accounted for. Hence the model is incorrect.

What is density measured in... for example if i had 68 what would be the suffix for that

Airida [17]

It depends.

If the volume is mL and the mass is g, then the "suffix" would be g/mL.

If the volume is cm3 and the mass is g, then the "suffix" would be g/cm3.

The following reaction was carried out in a 3.00 L reaction vessel at 1100 K:

Nady [450]

Answer:

$Q=0.840$

Explanation:

Hello,

In this case, since the given undergoing chemical reaction is correctly balanced, the reaction quotient is computed as well as the equilibrium constant but in terms of the given concentrations that are:

$C_{C}=\frac{5.25mol}{3.00L} =1.75M\\C_{H_2O}=\frac{12.2mol}{3.00L} =4.07M\\C_{CO}=\frac{3.90mol}{3.00L}=1.30M\\C_{H_2}=\frac{7.90mol}{3.00L} =2.63M$

In such a way, the reaction quotient turns out:

$Q=\frac{C_{CO}C_{H_2}}{C_{H_2O}}=\frac{1.30M*2.63M}{4.07M}\\ Q=0.840$

Taking into account that carbon is not included since it is solid.

Best regards.
