Answer:

4 hydrogen atoms are attached with the carbon atom in the molecule.

Explanation:

Hydrocarbon molecule is a type of molecule which is composed of hydrogen and carbon atoms. Carbon atom belongs to group 4 in the periodic table which means it has four electrons in its outermost shell or orbit, so for attaining octet rule, carbon atom makes 4 covalent bonds with 4 hydrogen atoms and 4 electrons of hydrogen atom is used by the carbon atom and becomes a stable molecule.

A 250. ML sample of 0.3M HCl is partially neutralized by the addition of 100. ML of 0.25M NaOH.Find the concentration of hydroch
Dahasolnce [82]

Answer:- 0.143 M

Solution:- HCl and NaOH reacts in 1:1 mol ratio as shown in the below reaction:

HCl(aq)+NaOH(aq)\rightleftharpoons NaCl(aq)+H_2O(l)

Let's calculate the initial moles of HCl and the moles of NaOH added to it:

250.mL(\frac{1L}{1000mL})(\frac{0.3molHCl}{1L})

= 0.075 mol HCl

100.mL(\frac{1L}{1000mL})(\frac{0.25molNaOH}{1L})

= 0.025 mol NaOH

Since they react in 1:1 mol ratio, 0.025 mol of NaOH will react with 0.025 moles of HCl.

Remaining moles of HCl = 0.075 - 0.025 = 0.050

Total volume of the resulting solution = 0.250 L + 0.100 L = 0.350 L

So, the concentration of HCl in the resulting solution = \frac{0.050mol}{0.350L}

= 0.143 M

Hence, the concentration of HCl acid in the resulting solution is 0.143 M.

Which sentence contains a double negative?
wlad13 [49]
<h2>Answer:</h2>

She never danced with nobody.

Explanation:

The double negative is intended to convey to the reader a negative sentiment while emphasizing and reinforcing that notion. The double negative may be seen in sentences that include two words that have a negative connotation yet are in perfect harmony with the other words in the phrase as well as with the sentences' coenrency and cohesiveness.

There are two negative terms in the sentence "She never danced with nobody." These are the words "never" and "nobody," which are perfectly in sync with the rest of the sentence's components. So, here's an excellent example of a double negative statement.
