True or False? pH can only be between 1 and 14.TrueFalse

Chemistry
1 answer:
Alika [10]1 year ago
7 0

Answer: The sentence given is false.

Explanation:

The question requires us to determine if the sentence given by the question ("pH can only be between 1 and 14") is true or false.

The pH value is matematically defined as:

pH=-log\lbrack H^+\rbrack

where [H+] is the concentration of H+ ions in solution.

If the concentration of H+ is too high, such as in an acid battery, the pH of a solution can reach 0. However, its value cannot be negative. Therefore, we can say that the pH scale ranges from 0 (very acidic medium) to 14 (very alkaline medium).

Considering the sentence given, we can say that it is false.

A chemist examines an ionic compound that contains magnesium and one other element. She
Igoryamba

Group 7

Explanation:

The unknown element belongs to the seventh group on the periodic table of elements.

Ionic bonds are usually formed between metals and nonmetals. They formed by the transfer of electrons from the less electronegative specie to the more electronegative one.

The metals usually lose electron because they are highly electropositive species.

  • If we have a magnesium atom with two valence electrons.
  • To form ionic bonds, it must transfer the two electrons to another atom.
  • The other atom, a nonmetal must be ready to accommodate and receive the donated electrons.
  • This ensure that its own octet is complete.
  • Group 6 elements requires 2 electrons to have a complete octet.
  • They can receive the two electrons

But we were told that there are two atoms of that element for each of the magnesium atom;

  the atom must have a capacity of collecting one electron each to be stable.

Such atoms are found in Group 7 on the periodic table.

When 3.4 moles of hydrogen gas react with excess oxygen how many moles of water will be produced
s344n2d4d5 [400]
1. start with balanced equation.
2 H2(g) + O2(g<span>) </span><span> 2 H</span>2O(g<span>)
</span>
2. Use stoichiometry 
(3.4moles of H)(2moles of H2O/2moles of H)
The moles of H will cancel, leaving you with moles of H2O. 
The answer is 3.4 moles of H2O
