Write the complete ionic equation for the reaction that takes place when aqueous solutions of strontium hydroxide and lithium ph

Nesterboy [21]

Answer : The net ionic equation will be,

$3Sr^{2+}(aq)+2PO_4^{3-}(aq)\rightarrow Sr_3(PO_4)_2(s)$

Explanation :

In the net ionic equations, we are not include the spectator ions in the equations.

Spectator ions : The ions present on reactant and product side which do not participate in a reactions. The same ions present on both the sides.

The given balanced ionic equation will be,

$3Sr(OH)_2(aq)+2Li_3PO_4(aq)\rightarrow 6LiOH(aq)+Sr_3(PO_4)_2(s)$

The ionic equation in separated aqueous solution will be,

$3Sr^{2+}(aq)+6OH^{-}(aq)+6Li^{+}(aq)+2PO_4^{3-}(aq)\rightarrow Sr_3(PO_4)_2(s)+6Li^+(aq)+6OH^{-}(aq)$

In this equation, $Li^+\text{ and }OH^-$ are the spectator ions.

By removing the spectator ions from the balanced ionic equation, we get the net ionic equation.

The net ionic equation will be,

$3Sr^{2+}(aq)+2PO_4^{3-}(aq)\rightarrow Sr_3(PO_4)_2(s)$

PLEASE HELP!!! Calculate the PH of an acid solution containing 0.10 M HNO3

Anika [276]

Answer:

The pH would be 1.

Explanation:

The pH of an acid can be found by using the formula pH = - log [H⁺]. This was a method developed to be able to measure the pH of substances.

Since the concentration of HNO₃ is 0.1 M, then it also means that the concentration of H⁺ ions is 0.1 M.

By substituting for the formula: pH of 0.1 M HNO₃ = - log [0.1]

= 1

Write the balanced equation for a reaction between aqueous nitric acid (HNO3) and solid lithium metal (this is a single replacem

Lemur [1.5K]

Answer: The equation is given below.

Explanation:

Single replacement reactions are the chemical reactions in which more reactive metal displaces a less reactive metal from its chemical reaction. General equation for these reactions is given by the equation:

$A+BC\rightarrow AC+B$

Metal A is more reactive than metal B.

The reactivity of metals is judged with the help of reactivity series. In this series, the metals lying above are more reactive than the metals which lie below in the series.

For the reaction of solid lithium metal and nitric acid, the equation follows:

$3Li(s)+4HNO_3(aq.)\rightarrow 3LiNO_3(aq.)+2H_2O(l)+NO(g)$

This is a type of single replacement reaction because Lithium (more reactive metal) is replacing Hydrogen (less reactive metal) from the chemical reaction.
