Answer: It depends on the concentration of all solutes in the solution (ie, its osmolarity). A solution with low osmolarity is hypotonic and vice versa. Solutions having the same osmolarity are isotonic. Water in pools and rivers is hypotonic compared with sea water, but water from the Dead Sea is hypertonic.We do not swell and pop when we go swimming in a hypotonic swimming pool because our skin protects us from the external environment and does not let water cross into or out of our body surfaces. ... hope this helps have a great day
Explanation:
The transition metals are a group of metals that are found in the middle of the periodic table. ... They are also harder than the post transition metals. They make colorful chemical compounds with other elements. Most of them have more than one oxidation state.
The more acid the salt, the lower the pH. So we must find the salt that is most basic among the options. Our answer is
, because it is formed by a weak acid (
) with a strong base (
).
Answer is: amount of sugar in milk chocolade is 3333 mg.
To solve this question, make proportion: if 12,00 grams of milk chocolate contain 8,00 grams of sugar, than 5,00 grams contain:
12,000 g : 8,000 g = 5,000 g : m(sugar).
12,000 g · m(sugar) = 8,000 g · 5,000 g.
m(sugar) = 40,000 ÷ 12,000.
m(sugar) = 3,333 g = 3333 mg.
Answer:
- Not balanced.
- Reactants: Zn and HCI
.
- Products: ZnCl₂ and H₂.
- Substitution reaction.
Explanation:
Hello,
In this case, for the given reaction:
Zn + HCI → ZnCl₂ + H₂
We can see that it is not balanced due to the fact that at the left side we have one hydrogen atom whereas at the right side two, taking into account the number must be same as well as chlorine. Thus, in order to balance we write:
Zn + 2HCI → ZnCl₂ + H₂
And that is enough. Moreover, we can see that the chemical species at the left side of the equation are the reactants and those at the right side the products, thus we have:
Reactants: Zn and HCI
.
Products: ZnCl₂ and H₂.
Finally, since we can see that the chlorine is at the reactants with hydrogen, but at the end with the zinc, and the initial zinc is alone as well as the yielded hydrogen we can infer this is a substitution reaction.
Best regards.
