Answer: C. The number of atoms of each element is the same on each side of the equation.
Explanation:
The Law of Conservation of Matter shows that it is not possible for matter to either be created nor for it to be destroyed so the number of atoms of each element on the reactant side of the equation must equal the number of atoms in each element on the product side of the equation.
This is why the following equation is incomplete:
H₂ + O₂ ⇒ H₂O
The oxygen atoms are not the same on either side.
Equation will therefor have to be balanced which will make it:
2H₂ + O₂ ⇒ 2H₂O
Notice now that atoms are the same on both sides.
A I think because each side cancels out the other opposite side
Potassium is fundamental for neuron activity. If a body does not have enough potassium, then the neuron will struggle to fire because there will not be enough positively charged ions to trigger the firing of the neuron.
The potassium (K+) is maintained at a high level within the neuron at rest, whereas sodium (Na+) is maintained at a high level outside of the cell.
Neurons contain K+ and Na+ leakage channels that allow the two ions to diffuse in favor of a concentration gradient.
Depolarization opens both K+ and Na+ channels in the membrane, thereby these ions can flow out and into the axon, respectively.

Answer: B
Explanation:
Poking a hole and adding air to a ballon will have no effect on kinetic energy since they don’t affect temperature.
