Answer:
The element potassium forms a cation with the charge +1 . The symbol for this ion is K⁺, and the name is potassium ion. The number of electrons in this ion is 18.
Explanation:
Potassium is a metal. It belongs to the group 1 elements. Metals form cations by losing electrons. Since potassium is a group element, it forms a cation by losing one electron. The charge it has is +1 due to the excess of the protons compared t the electrons by 1.
Potassium has 19 electrons. Potassium io on the other hand has 19-1 = 18 electrons.
Chlorofluorocarbons and other halogenated ozone depleting substances are mainly responsible for man made chemical ozone depletion.
1. 25 ml
2. 0.56 M
3. 3.0x 10^-2 M
Step by step explanation as follow
Use the formula (Molarity x volume) = ( molarity x volume)
<span>The molar ratios of NaOH to Al(OH)3 are 3 to 1. Therefore, 2.3 moles of NaOH would produce (1/3)*(2.3) moles of Al(OH)3. </span>
