Answer:
In order for frost to be formed, you would need high humidity, below-freezing temperatures, a clear sky, and a calm wind. Also, note that frost mostly occurs on a surface that is solid, so I would also put in a hard surface to the answer.
Explanation:
You need the hard surface so that the frost can form, otherwise it would become something like a cloud.
You need high humidity so that there is lots of water to form on your solid surface.
You need below-freezing temperatures so that the water can freeze.
The other things are just from what the Internet told me.

As with most stoichiometry problems, it is necessary to work in moles. The ratio of the moles of each element will provide the ratio of the atoms of each element.
Get the mass of each element by assuming a certain overall mass for the sample (100 g is a good mass to assume when working with percentages).
Remeber that percentages are a ratio multiplied by 100. You must convert percentages back to their decimal value before working with them.
(.4838) (100 g) = 48.38 g C
(.0812 ) (100 g) = 8.12 g H
(.5350) (100 g) = 53.38 g O
Convert the mass of each element to moles of each element using the atomic masses.
(48.38 g C) (1 mol/ 12.10 g C) = 4.028 mol C
(8.12 g H) (1 mol/ 1.008 g H) = 8.056 mol H
(53.38 g O) (1 mol/ 16.00 g O) = 3.336 mol O
Find the ratio or the moles of each element by dividing the number of moles of each by the smallest number of moles.
Use the mole ratio to write the empirical formula.
Answer:
B. 12.8 mL
Explanation:
B is the right answer because the volume of the fluid is <em>12.8</em><em> </em><em>mL</em>
The removal of excess wastes helps in maintaining chemical homeostasis and prevents breaking down of systems that causes a serious health issue.
<u>Explanation:</u>
Human body is composed of many different organ system that are inter related with each other's functions. If the function of one system is disturbed then the function of other system also gets affected resulting in affecting the entire human body functions. The system that is used to remove the excess wastes and unwanted things from the human body is an excretory system. It performs tow major function in a human body. It removes unwanted things and it also helps in draining the broken down components.
The excretory system helps in the control of internal chemical homeostasis. When a living organism's physical and chemical conditions are maintained steadily it is called as homeostasis. This system also helps in maintaining the human systems in a controlled and good condition thereby preventing the failure of other systems and serious health damages.
Answer:
write the balanced chemical equation of the reaction between strong acid and weak base also mention the types of salt obtained in the reaction
Explanation:
HCl → H+(aq) + Cl−(aq) (100%)
Any acid that dissociates 100% into ions is called a strong acid. If it does not dissociate 100%, it is a weak acid. HC2H3O2 is an example of a weak acid:
HC2H3O2→ H+(aq) + C2H3O2−(aq) (~5%)
Because this reaction does not go 100% to completion, it is more appropriate to write it as an equilibrium:
HC2H3O2 ⇄ H+(aq) + C2H3O2−(aq)
As it turns out, there are very few strong acids, which are given in Table 12.2 “Strong Acids and Bases”. If an acid is not listed here, it is a weak acid. It may be 1% ionized or 99% ionized, but it is still classified as a weak acid.
