Answer:
<em>Recall the following terms which is,</em>
<em> KHP is Potassium hydrogen phthalate</em>
<em>NaOH is Sodium Hydroxide </em>
<em>NaKP is molar mass</em>
<em>H20 is water</em>
Explanation:
<em>KHP + NaOH = NaKP + H2O
</em>
<em>moles of KHP = 0.3480g / 204.22 g·mol−1 = .001704
</em>
<em>these will react with the same number of moles of NaOH according to the equation </em>
<em>these are in 0.03207 L of solution </em>
<em> The molarity of the NaOH solution = 0.001704 mol / 0.03207 L = 0.0531 M
</em>
<em>the water takes no part in the reaction and the quantity can be ignored
</em>

Answer:
Decomposition reaction = Those reactions in which single compound decompose down to give two or more products are called decomposition reaction .
Explanation:
Those reactions in which single compound decompose down to give two or more products are called decomposition reaction .
For the Decomposition reaction to take place , <u><em>a large amount of energy ias needed</em></u>. This is because for decomposition bonds are required to breaks. Hence energy is needed to break the bonds as they have strong force of attraction.
They occur in presence of HEAT , LIGHT , ELECTRICITY.
examples of decomposition reactions are:
Here only one CaCO3 is producing two substances which are : CaO and CO2
This is also known as decompositon of Calcium carbonate and it require a lot of heat energy.
This is also a decomposition reaction , This occur in the presence of sunlight
Five atoms in the pictured molecule
Explanation:
In the molecule, the structure is as depicted below;
H H H
H....N -- C---C--O...H
H H
A hydrogen bond forms when an hydrogen atom becomes partially positively charged as it is connected to a more electronegative atom such as O, N and F.
The two hydrogen on N and one hydrogen on O will form hydrogen bond with the Oxygen on water molecule.
The nitrogen and oxygen will also bond with hydrogen of water.

The answer is Mixture. Two more substances put together but each retaining their own identity is a Mixture. They are t<span>wo or more substances dispersed in one another but each retaining their own identity.</span>
The potassium chloride is KCl. The gram formula mass of KCl is 39+35.5=74.5 g/mol which means 74.5 g per mole of KCl. So the mass of KCl is 6.90*74.5=514 g.
