The process of seeking facts that will lead to the truth is called _____.study
research
intuition

Answers

Answer:

The given blank can be filled with research.

Explanation:

The procedure of looking for facts, which will lead to the truth is known as research. In the absence of research one cannot conclude that the facts or statements are right. Research is illustrated as a systematic and creative work performed to enhance the stock of knowledge, comprising knowledge of culture and society, humans, and the application of this knowledge stock to device novel uses.

The process of seeking facts that will lead to the truth is called research.

Explain, in terms of both atoms and molecular structure, why there is no isomer of CH3OH.

Answers

Explain, in terms of both atoms and molecular structure, why there is no isomer of CH3OH.

There is no isomer of CH3OH or methanol because it contains only one carbon atom. And also, the structure is tetrahedral, having four substances attached to the carbon atom.

Suppose you wanted to dissolve 109 g of sodium carbonate in enough water to make 6.00 L of solution. What is the molarity of this solution?

Answers

Molarity

a. Na2CO3
Molar mass = 106 g/mol
n= 109 g / (106 g/mol) = 1.028 mol

b. 6.00L

c. M=n/V
M = 1.028 mol / 6.00 L
M= 0.1713 mol / L

Answer: The molarity of the sodium carbonate solution is 0.1713 mol/L

true or false: ionic bonding involves the shareing of electrons, oxide ions have a 2+ charge , electrons have a negative charge , a hydrogen molecule is held together by a strong covalent bond between two hydrogen atoms, a covalent bond is a shared pair of electrons.

Answers

Ionic bonding does not involve the sharing of electrons, that one is false. In ionic bonding, the metal's electrons are given to the non-metal, so that they're both like the nearest noble gas (full electron shells.) They are then drawn together because one has a negative charge (the non-metal) and one has a positive charge (the metal.)

Oxide ions have a 2+ charge: This is false, oxide ions have a 2- charge.

Electrons do have a negative charge, this is true.

Hydrogen molecule: pretty sure this is true. We know this because both atoms are non-metals.

The last one is true: a covalent bond is a shared pair of electrons between two atoms, however be aware that there can be more than one covalent bond between two molecules.

Answer:

False , shared electrons cause covalent bonds
False , they have 2- charge
True
