(Relative atomic mass: S=32,0=16)
(A) 0.56 g
B) 5.6 g
(C) 56 g
C) 560g
The mass of oxygen gas contains the same number of moles as 56g of sulphur is 56g
Calculation,
Number of moles of sulphur = given mass/ molar mass of sulphur
Number of moles of sulphur = 56/ 32 moles
Number of moles of sulphur = 1.75 moles
According to question,
Number of moles of sulphur = Number of moles of oxygen(O2)
So, Let mass of oxygen be X.
Number of moles of oxygen = X/16×2 = 1.75 moles
Mass of oxygen (X) = 1.75×16×2 grams
Mass of oxygen (X) = 56 grams
The 6.022×1023 of chemical species like an electrons, molecules atoms, ions etc is called moles

Answer:
C. 56 g
Explanation:
56 g S (1 mol S/ 32 g) = 1.75 mol S
1.75 mol O2 (32 g/ 1 mol O) = 56 g O2
b. hydration
c. deliquescent
d. solvation
Let us understand all the terms
Hydration : this is the addition of water to anything. It can be addition of water to double or triple bond, absorption of water by a substance. so it cannot be loss of water.
Deliquescent : it is the absorption of water by a substance and getting dissolved in it. Like NaOH is a deliquescent substance.
Solvation: It is the phenomenon where a substance get surrounded by solvent molecules. If solvent is water it is known as hydration.
Thus the answer is
effloresce : where a substance loses water.
Answer:
C. All electron carriers are mobile and hydrophobic
Explanation:
Hello,
In this case, it is widely known that the electron carriers move inside the inner mitochondrial membrane and consequently move electrons from one to another. In such a way, they are mobile, therefore they are largely hydrophobic as long as they are inside the membrane.
For instance, the cytochrome c is a water-soluble protein in a large range, therefore, the answer is: C. All electron carriers are mobile and hydrophobic.
Best regards.

Carbon has 4 valence electrons and has a close electronegativity like that of hydrogen and other nonmetals. Because of this, it tends to form covalents bonds equally spaced around it. The best association to this is the lewis structure for methane,CH4.
Carbon has the ability to for covalent bonds with other elements beside from itself. These bonds are the: single covalent bond; the double covalent bond; and, triple covalent bond.
Answer: Option (3) is the correct answer.
Explanation:
In the process of oxidation, an atom loses electrons or an increase in oxidation number of the atom occurs.
For example, is an oxidation process.
Whereas in a process of reduction, an atom gain electrons or a decrease in oxidation number of the atom occurs.
For example, is a reduction process.
Thus, we can conclude that the chemical process in which electrons are gained by an atom or an ion is called reduction.
