Answer:

Boiling points increase as number of carbon increases

Explanation:

Alkanes have 3 carbons, while alcohols have 6. This means that alcohol has a higher boiling point.

Do the number of protons in an atom of an element always equals its atomic weight.

Elenna [48]

No. The number of a protons is not equal to it's atomic weight, instead it is equal to the 'atomic number'

Answer:

It has its elements with mass numbers phrased in many decimal places, it requires one to round off to get the actual value.

The atomic numbers of some elements such as Protonium were just guessed.

g What is the molarity of hydrochloric acid if 40.95 mL of HCl is required to neutralize 0.550 g of sodium oxalate, Na2C2O4

kykrilka [37]

Answer:

0.0002 M

Explanation:

The molarity of the HCl required would be 0.0002 M.

First, let us consider the balanced equation of the reaction:

$Na_2C_2O_4 + 2HCl = 2NaCl + H_2 + 2CO_2$

Stoichiometrically, 1 mole of $Na_2C_2O_4$ reacts with 2 moles of $HCl$ for a complete neutralization reaction.

Recall that: mole = $\frac{mass}{molar mass}$

Mole of 0.550 g sodium oxalate = 0.550/134 = 0.0041 mole

If 1 mole $Na_2C_2O_4$ requires 2 moles HCl, then 0.0041 mole will require:

0.0041 x 2 = 0.0082 mole HCl

Volume of the HCl = 40.95 L

Molarity = mole/volume

Hence, molarity of the HCl = 0.0082/40.95 = 0.0002 M
