Formula for Ni2+ and NO3

lyudmila [28]

The formula of a compound is $Ni(NO_3)_2$

Given:

The ions $Ni^{2+}$ and $NO_3^-$

To find:

The formula for ions $Ni^{2+}$ and $NO_3^-$

Solution:

The ion with a positive charge (cation) = nickel ion = $Ni^{2+}$

The ion with a negative charge (anion) = nitrate ion = $NO_3^-$

Valency on nickel ion = 2

Valency on nitrate ion = 1

Using the criss-cross method as shown in image

Explain what happens in a nuclear chain reaction

Vesnalui [34]

Answer:

Nuclear Chain Reactions. A chain reaction refers to a process in which neutrons released in fission produce an additional fission in at least one further nucleus. This nucleus in turn produces neutrons, and the process repeats. The process may be controlled (nuclear power) or uncontrolled (nuclear weapons).

Which of the following reactions is the least energetic? Question 18 options: ATP + H2O → ADP + Pi ATP + H2O → AMP + PPi AMP + H

Mama L [17]

Answer:

The correct answer is AMP+H2O→ Adenosine + pi

Explanation:

The above reaction is least energetic because there is no phosphoanhydride bond present with adenosine mono phosphate.Phospho anhydride bond is an energy rich bond.

As a result hydrolysis of AMP generates very little amount of energy in comparison to the hydrolysis of ATP and ADP.
