An ionic equation is a chemical equation in which the electrolytes in aqueous solution are described as dissociated ions.
<h3>What is the difference between ionic equation and net ionic equation?</h3>
- A complete ionic equation also contains the spectator ions, whereas a net ionic equation just displays the chemical species that are involved in a reaction.
- A molecular formula has two or more atoms bonded together, whereas a chemical formula can only refer to one atom. They are both elements, and their chemical symbols are unchanged.
- An ionic equation is a chemical equation in which the electrolytes in aqueous solution are described as dissociated ions. It is similar to a molecular equation in that it expresses compounds as molecules.
3FeSO4(aq) + 2K3PO4(aq) = Fe3(PO4)2(s) + 3K2SO4(aq)
ionic equation : 3Fe(2+)(aq) + 3SO4(2-)(aq)+ 6Na(+)(aq) + 2PO4 (3-) (aq) → Fe3(PO4)2(s)+ 6Na(+) + 3SO4(2-)(aq)
net ionic equation: 3Fe(2+)(aq) + 2PO4 (3-)(aq) → Fe3(PO4)2(s)
K2CO3(aq) + CdI2(aq) = 2KI(aq) + CdCO3(s)
net ionic equation for K2CO3(aq) + CdI2(aq) = 2KI(aq) + CdCO3(s).
2HNO3 + CaCO3 = Ca(NO3)2 + H2O + CO2
ionic equation : CaCO3(s) + 2H+(aq) → Ca2+(aq) + CO2(g) + H2O()

Answer: B) 4.2 M
Explanation:
Molarity = moles of solute/litre of solution
1560mL/1000 = 1.56 litres
6.5/1.56 = x/1
x = 4.2
M of solution = 4.2
Answer:
Both metals and non-metals when burnt in oxygen form their oxides. Oxides of metals are basic in nature and oxides of non-metals are acidic in nature.
After the addition of 6.47 mL of 0.303 M HCl. Solution :- lets first calculate the moles of the NaOCl and HCl Moles = molarity *volume in liter Moles of NaOCl = 0.100 mol per L * 0.053 L =0.0053 mol Moles of HCl =0.303 mol per L *0.00647L=0.00196
Answer:
<h3>The answer is 0.67 cm³ </h3>
Explanation:
Density of a substance can be found by using the formula
<h3>
</h3>
Making volume the subject we have
<h3>
</h3>
From the question
mass of gold nugget = 13 g
Density = 19.3 g/cm³
Substitute the values into the above formula and solve for the volume
We have
<h3>
</h3>
= 0.673575
We have the final answer as
<h2>0.67 cm³</h2>
Hope this helps you
