How many atoms of hydrogen are found in the compound, NH4C2H302?

Chemistry
1 answer:
Mariulka [41]3 years ago
8 0
<h2>Answer:</h2>

7 hydrogen atoms

<h2>Explanation:</h2>

N<em><u>H4</u></em>C2<em><u>H3</u></em>02

In this problem we see the hydrogen atom twice, along with the numbers 4 and 3 next to them. (as shown above in bold & underlined)

So, in order to find how many there are in all you add both hydrogen atoms together-

H4+H3= H7

therefore, there are 7 hydrogen atoms in all

C16H32O2(aq) --> 16CO2(g) + 16H2O(l) ... said its wrong though? 
<span>This is because you haven't added any oxygen needed for the combustion, so your equation does'nt balance. Also a solution in water [aq] doesn't burn! </span>

What volume of water is needed for 0.196 mol of CdCl2 to prepare a 3.91 M solution? L
Brilliant_brown [7]

0.050 litres of the water will be required to make a 3.91 M solution with 0.196 moles in it.

Explanation:

Data given:

moles of CdCl_{2} = 0.196 Moles

Molarity of the solution = 3.91 M

Volume in litres =?

molarity is calculated by the formula:

molarity = \frac{number of moles}{volume in litres}

putting the values in the above formula and rearranging it for volume:

volume = \frac{number of moles}{molarity}

volume = \frac{0.196}{3.91}

volume = 0.050 litres

0.050 litres of the water will be required to make a 3.91 M solution with 0.196 moles in it.

Molarity is the number of moles present in a given volume of solution which is given in litres. It is the measurement of the concentration of particular solute in a solution.

Even though the molecular formula of acetylene is C2H2, and that of benzene is C6H6, these compounds have the same percent compo
alexandr402 [8]

Answer:

CH

Explanation:

The empirical formular is the simplest formular of a compound. It shows the relative number of elements present in a compounds. It shows the number of atoms of elements present in simple ratios.

In both compounds, the ratio of the carbon to hydrogen s 1:1

In C2H2;

C : H = 2 : 2 (Which is equivalent to 1 : 1)

In C6H6;

C : H = 6 : 6 (Which is equivalent to 1 : 1)

This means the empirical formular is CH
