Movement of particles from areas of greater to lesser is called diffusion.
The answer is C. One item replacing another is a single replacement, but when two items trade places in two separate molecules it’s double replacement.
Answer:
0.95g of Ag we can produce
Explanation:
To solve this question we have to convert the mass of silver nitrate (AgNO₃) to moles. The moles of silver nitrate = Moles of Ag. Then, with molar mass of Ag we can know the mass of silver:
<em>Moles AgNO₃ -Molar mass: 169.87g/mol-:</em>
1.5g * (1mol / 169.87g) = 0.0088 moles Ag
<em>Mass Ag -Molar mass: 107.87g/mol-:</em>
0.0088 moles Ag * (107.87g / mol) =
<h3>0.95g of Ag we can produce</h3>

Answer:
Burning of the candle is both physical and chemical change. Burning of the candle melts the wax and hence physical state of wax has changed from solid to liquid.
Again the wax combines with the atmospheric oxygen and changes to carbon dioxide, heat and light.
Thus both the changes are accompanied by the burning of the candle.
