The element that was oxidized is carbon, as it’s oxidation state increased (electrons were lost) from +2 (in the reactants) to +4 (in the products). The element that was reduced is nitrogen, as it gained electrons and went from a +2 oxidation state (reactants) to a 0 oxidation state (products). Since the carbon was oxidized and it’s electrons were used to reduce the nitrogen, carbon is the reducing agent.
True
According to the molecular theory. The average kinetic energy of a gas particle is directly proportional to the temperature. An increase in temperature increases the speed in which the gas molecules move. All gases at a given temperature have the same average kinetic energy.
<span>In my opinion, it is a rotten question, phrased as it is. It all depends on how much acid and how much base. It also depends on the type of acid (sulfuric acid reacts differently than hydrochloric - sulfuric has two atoms of hydrogen compared to hydrochloric which has one atom of hydrogen per molecule). It also can depend on the concentration - for example, if you're mixing a one molar solution of acid with a two molar solution of base, and on how much you are mixing - if you are mixing one liter of base with one liter of acid, or whatever. Your instructor needs to establish these things in order to make it a question you can actually answer.
But, your instructor probably means what happens if you add the same amount of an acid and a base together, and they have the same strength. Ideally, if you mix the same amounts of an acid and a base, and the acid has one atom of hydrogen, then you would get water plus a salt, which would have a neutral pH.
For example, HCl + NaOH, mixed in the same amounts and at the same concentrations would give you HOH (or water) plus NaCl (which is actually table salt). All acids and bases that are mixed in these equal concentrations always give you water plus a salt (although not always table salt - just what is chemically known as a "salt).</span>
Answer: a primary succession would most likely occur after any natural disaster including wildfires, tornados, or huricans.
Answer:
<h3>The answer is 7.21 g/mL</h3>
Explanation:
The density of a substance can be found by using the formula
From the question
mass of metal = 86.5 g
volume = 12 mL
The density is
We have the final answer as
<h3>7.21 g/mL</h3>
Hope this helps you
