Answer:
NiCO3 (s) + 2H+ (aq) → H2O (l) + CO2 (g) + Ni2+ (aq)
Explanation:
To write the complete ionic equation:
1. Start with a balanced molecular equation.
2. Break all soluble strong electrolytes (compounds with (aq) beside them) into their ions
3. indicate the correct formula and charge of each ion
4. indicate the correct number of each ion
5. write (aq) after each ion
6. Bring down all compounds with (s), (l), or (g) unchanged.
<span>Answer: 56.6 moles
Explanation:
28.3 moles of Pb would produce twice as much moles as Ag.
28.3 X (2moles Ag/ 1 mol Pb) = 56.6 moles of Ag.</span>
Answer:
The solute is the substance that is being dissolved,
Explanation:
A solution is a homogeneous mixture consisting of a solute dissolved into a solvent .
A whole number, not a fraction, that can be negative, positive or zero are integers. They cannot have decimal places.
Now, converting 0.000431 L to decimal an integer as:
Since, 
So, 
.
Hence, the integer value for 0.000431 L is 
.
