If this helps let me know
<span>The
limiting reagent is the one that will be all used up if the reaction
goes to completion. There is not enough of it present to use up all the
other reagent (which is in excess). :)

When they are mixed it will be warm b/c bonds r being broken
Answer:
<u></u>
Explanation:
<u>1. Calculate the number of moles of NiCl₂</u>
a) Identify the known variables
- V =0.800 liters
- M = 0.531M
- n = ?
b) Formula
c) Clear n
<u>g) Substitute and compute</u>
<u>2. Convert moles to grams</u>
a) molar mass of NiCl₂
- 129g/mol (shown in the problem)
b) Unit canceling method
Use the factors in order to cancel the units to obtain grams
Note that the mol unit appears on the numerator and denominator, so it cancels leaving just g (grams).
c) Round to 3 signficant figures
Answer:
reaction 1 and reaction 4 both are decomposition reactions
while reaction 2 is double displacement reaction and reaction 3 and 5 are combination reactions
Answer:
Electrical energy to mechanical energy
Explanation:
In an electric motor, the energy transformation that is involve is a move from from electrical energy to mechanical energy.
For every system, according to the law of conservation of energy "energy is neither created nor destroyed but transformed from one form to another".
- An electric motor converts electrical energy to mechanical energy
- The electrical energy passes through and electromagnet set up.
- This then cause the motion to rotate.
- Therefore, electrical energy is transformed to mechanical energy.
