Answer:
c. Atoms of two or more elements bond together
Explanation:
a chemical reactions forms products ( new substances); where it rearranges themselves to form new bonds.
Answer:
the answer is A
Explanation:
Hopefully u get the answer right
The boiling point and distillation temperature of a substance are the same. The answer would be True
2 C2H2 + 5 O2 --> 4 CO2 + 2 H2O
2.35 mol C2H2 - x mol O2
2 mol C2H2 - 5 mol O2
![x = \frac{2.35 \times 5}{2} = 5.875 \: mol](https://tex.z-dn.net/?f=x%20%3D%20%20%5Cfrac%7B2.35%20%5Ctimes%205%7D%7B2%7D%20%20%3D%205.875%20%5C%3A%20mol)
answer: 5.875 mol
Answer: Option (c) is the correct answer.
Explanation:
HF is a weak acid and not a strong acid. This is because fluorine is a highly electronegative atom and when it combines with a hydrogen atom then it will attract the valence electron of hydrogen atom more towards itself.
As a result, it will not dissociates easily to give hydrogen ion. Hence, it acts as a weak acid.
A neutralization reaction is defined as a reaction in which an acid reacts with a base to give salt and water. For example, ![HCl + NaOH \rightarrow NaCl + H_{2}O](https://tex.z-dn.net/?f=HCl%20%2B%20NaOH%20%5Crightarrow%20NaCl%20%2B%20H_%7B2%7DO)
It is true that, spectator ions "appear in the total ionic equation for a reaction, but not in the net ionic equation".
Titration is defined as a process in which concentration of an unknown solution is determined using a solution of known concentration.
Thus, we can conclude that the statement HF, HCl, and HNO3 are all examples of strong acids, is false.
