The molecular formula for Hydrocarbon = C₄H₁₀
<h3>
Further explanation:</h3>
Given
50 ml hydrocarbon
200 ml CO₂
250 ml H₂O
Required
The molecular formula of Hydrocarbon
Solution
From Avogadro's hypothesis, at the same temperature and pressure, the ratio of gas volume will be equal to the ratio of gas moles
So moles Hydrocarbon : CO₂ : H₂O = 50 ml : 200 ml : 250 ml = 1 : 4 : 5
mol C in 1 mol CO₂=1, and for 4 moles CO₂ there are 4 moles C
mol H in 1 mol H₂O =2, and for 5 moles H₂O there are 10 moles H
So mol ratio C : H in compound = C₄H₁₀
Molar mass is 28+32 = 60
So take 3.4 x 10^-7/60 and get about 5.7 x 10^-9
H₃As is stronger acid than H₂Se.
The H-A bond strength typically determines the size of the "As" atom in an acid; the smaller the "As" atom, the stronger the H-A bond. In the Periodic Table, the atoms get bigger and the bonds get weaker as you advance down a row, strengthening the acids.
<h3>What is acid?</h3>
Any molecule or ion that may donate a proton—a Brnsted-Lowry acid—or establish a covalent bond with a pair of electrons—a Lewis acid—is regarded as an acid. The first class of acids are the Brnsted-Lowry acids, often known as proton donors.
The compound is referred to chemically as lysergic acid diethylamide, or LSD as it is more commonly known. Using it may lead you to have a distorted perception of reality and objects because it has a potent hallucinogenic effect. LSD has an effect known as tripping.
Aqueous solutions of acids with a pH lower than 8 are frequently referred to as "acids," even though the term "acid" technically only refers to the solute.

Answer:
200 L per day
Explanation:
If there is 1 mg of F- per L of water, we can calculate the volume for 2 g like this:
1) Converse the toxic mass of fluoride to miligrams
1 g ------- 1000 mg
0.2 g ---- X
X = 200 mg
2) Calculate the liters of fluoridated drinking water that a person can consume to reach 200 mg
1 mg -------- 1 L
200 mg ---- X
x = 200 L
