I would say d but I’m not sure
13 because an atom has the same number of protons as neutrons
Answer: do that yourself dip
Explanation:
Answer:
A. The gas molecules possess kinetic energy.
Explanation:
The characteristics of the Ideal gases are given by the Kinetic Theory of gases which are as follows:-
Gases consist of particles in constant, random motion. They continue in a straight line until they collide with something—usually each other or the walls of their container.
Particles are point masses with no volume. The particles are so small compared to the space between them, that we do not consider their size in ideal gases.
No molecular forces are at work. This means that there is no attraction or repulsion between the particles.
Gas pressure is due to the molecules colliding with the walls
Oxidizing agent is that which is reduced and the reducing agent is that which is oxidized. Reduced is when the charged is decreased and oxidized when the charge is increased.
(1) 2Na + 2H2O(l) --> 2NaOH(aq) + H2(g)
The charge of Na in the reactant is 0 and the charge of Na in the NaOH is +1. Na is oxidized. Hence, it is the reducing agent.
The charge of H in H2O is +1 while that in H2 is 0. H is reduced. Hence, it is the oxidizing agent.
(2) C(s) + O2(g) --> CO2(g)
The charge of C in the reactant side is 0 and that its charge in CO2 is +4. C is oxidized. Hence, it is the reducing agent.
The charge of O in O2 is 0 while in CO2, its charge is -2. O is reduced. Hence, it is the oxidizing agent.
(3) 2MnO⁻⁴ + SO2 + 2H2O --> 2Mn²⁺ + 5SO2⁻⁴ 4H⁺
The charge of Mn in MnO⁻⁴ is 4+ while its charge in Mn²⁺ is 2+. Mn is reduced. Hence, it is the oxidizing agent.
The charged of S in SO2 is -4 while its charge in SO₂⁻⁴ is 0. S is oxidized. Hence, it is the reducing agent.
