Inert gases are highly electronegative true or false

Answers

Answer 1

Answer: False, noble ggasses don't have a electronicgativty as they have a full stabel octet and so they do not need any added electrons

What mass of oxygen gas contains the samenumber of moles as 56g of sulphur?
(Relative atomic mass: S=32,0=16)
(A) 0.56 g
B) 5.6 g
(C) 56 g
C) 560g

Answers

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

What is moles ?

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

The process of ___ occurs when a hydrate loses its water of hydration.a. effloresce
b. hydration
c. deliquescent
d. solvation

Answers

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.

A student assisting with the experiment would observe all of the following about the electron transport chain EXCEPT:A. Electrons are passed from carriers with lower reduction potential to those with higher reduction potential.B. The first electron carrier is also a proton pump.C. All electron carriers are mobile and hydrophobic.D. The electron carriers can transport a maximum of 2 electrons.

Answers

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.

Because of the atomic structure of carbon, it tends to form

Answers

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.

25 The chemical process in which electrons are gained by an atom or an ion is called(1) addition (3) reduction(2) oxidation (4) substitution

Answers

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, $Cu(s) \rightarrow Cu^(2+)(aq) + 2e^(-)$ 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, $2Ag^(+) + 2e^(-) \rightarrow 2Ag(s)$ 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.

It is the process of reduction. If you want to remember it, I recommend remember that gaining electrons 'reduces' charge, by increasing the negative number... If that makes sense XD
