Answer:
Inside balloon outward normal force.
Outside balloon compressing atmospheric force.
Explanation:
At ground level gases outside and helium inside are in static equilibrium with balloon as separating surface. Both balloon and atmospheric forces are compressing to maintain that state.
But as balloon moves upward because of less density of helium gas in balloon internal force of helium gas increases. At high altitude atmospheric pressure decreases due to gravitational pull and fluid nature of gas. So equilibrium reestablish and it start to expand at high altitude.
Answer:
nitrogen because it has less number of protons and electrons, thus a samller atomic mass
Explanation:
Answer:
Filtration
Explanation:
Evaporation could work, but it would take too long and might be harmful to the environment. This is not the answer.
Distillation is used to purify a substance. It is generally only used when separating two liquids. This is not the answer.
Filtration is where you would pour the liquid through a filter and collect the solid. This is the answer.
Chromatography is technique that is used to test whether something is pure. You would not be able to separate the two substances using this technique. This is not the answer.
Answer:
320 g.
Explanation:
Hello!
In this case, according to the balanced chemical reaction, we can compute the grams of copper I chloride produced by each reactant, as shown below:
Thus, since copper produces the fewest grams of CuCl, we infer it is the limiting reactant, therefore the correct mass of copper I chloride is 320 g.
Best regards!
