Answer:

1. Nonmetal

2. Nonmetal

3. Covalent

Explanation:

Methane is the molecule being described in this question. It has a chemical formula of CH4 where four hydrogen atoms are bonded to one central carbon atom. Carbon as well as hydrogen are non-metallic elements, which means that they can only share their valence electrons to form a COVALENT BOND.

A covalent bond is a type of chemical bond in which two atoms share their valence electrons. It occurs between two non-metallic atoms. In this molecule, CH4, carbon and hydrogen share their valence electrons to form a covalent bond.

What Is the difference between organic and inorganic matter?
Charra [1.4K]
Organic compounds are compounds that contain carbon atoms.

Organic matter is any waste product that occurs naturally (i.e. snake skin, feces, and other traces of life).

Inorganic matter would lack carbon compounds. Radioactive waste at nuclear power plants is inorganic.

The spontaneous reaction that occurs when the cell in the picture operates is as follows: 2Ag+ + Cd(s) ???? 2 Ag(s) + Cd2+ (A) V
Snowcat [4.5K]

Answer:

14. B    15. D    16. C     17. B

Explanation:

The spontaneous reaction that occurs when the cell operates is shown below:

2Ag^{+} + Cd_{(s)} ⇒2Ag_{(s)} + Cd^{2+}

We need to select the correct option from the list below for the following questions.

(A) Voltage increases. (B) Voltage decreases but remains > zero. (C) Voltage becomes zero and remains at zero. (D) No change in voltage occurs. (E) Direction of voltage change cannot be predicted without additional information.

14. A 50-milliliter sample of a 2-molar Cd(NO_{3})_{2} solution is added to the left beaker.

If a 50-milliliter sample of a 2-molar Cd(NO_{3})_{2}  solution is added to the left beaker, the voltage decreases but its value remains greater than zero. The correct option is B

15. The silver electrode is made larger.

If the silver electrode is made larger, no change in the value of the voltage since we don't have the idea of the initial value. The correct option is D.

16. The salt bridge is replaced by a platinum wire.

If the salt bridge is replaced by a platinum wire, there will be no passage of electrons because electrons can't pass through a platinum wire. Therefore, the voltage will be zero and remains at zero. The correct option is C.

17. Current is allowed to flow for 5 minutes.

If current is allowed to flow for 5 minutes, the voltage decreases but its value remains greater than zero. The correct option is B.
