Answer:
chemical change
Explanation:
because physical is like if something is happening inside your body
BTW
I hope this helps
Particles in a gas are far apart compared to a solid or liquid, allowing it not to have a definitive shape or volume. This also means that gases can fill any container and be easily compressed.
Hey there!:
Volume = 175.4 mL
density = 0.8786 g/mL
mass = ?
Therefore:
D = m / V
0.8786 = m / 175.4
m = 0.8786 * 175.4
m = 154.10644 g
hope this helps!
I am pretty sure the answer is 1.5*10^25
Answer: options B,D and F
Explanation:
Since redox reactions are those which involves both oxidation and reduction
In B , Cu is oxidized and S gets reduced
D, Na gets oxidized and hydrogen gets reduced
F, carbon gets oxidized and Oxygen gets reduced
In g, there is no change in oxidation no of s in both product and Reactants is same +4
Similarly in the case of Ag and Mg.
