Answer:
Metal, Copper, and Alluminum
Explanation: It is what it is
A chemical change creates a new substance
Object A at 40
degrees C and object B at 80 degrees C are placed in contact with each other.
The heat flow will flow from the Object B to the object A because of temperature
difference. To attain equilibrium, the heat flow must flow form a higher
temperature to a lower temperature.
The mass of oxygen required is 17.06 g; the mass of carbon dioxide produced is 300 g; the mass of copper (ii) nitrate produced is 16.7 g.
<h3>What is the equation of the synthesis of water from hydrogen and oxygen?</h3>

Answer:
32
Explanation:
You have 7 valance electrons in fluorine, and you have 4 of them. 7*4=28. Then, you have 4 valance electrons on carbon. So 28+4=32
