Answer from: ARandomPersonOnline

False

Explanation:

''A mixture is the chemical bonding of two or more substances in any proportion'' is false statement because a mixture don't include bonding of chemical substances.

Mixtures in chemistry are including blending of substances and we have two tipes of mixture:

HeterogeneousHomogeneous

Some of the chemical mixtures are: mixture of water and sand, mixture of sand and iron filings and more...

If we are talking about bonding in chemistry there are Covalent bonds and Ionic bonds.

Answer from: lachlyn40

The statement is False.

Explanation:

A mixture contains two or more elements present in it.

The elements are not in chemical combination with each other.

A compound too contains two or more elements but they are in chemical combination.

For example NaCl is a compound which contains 1 part of Sodium and 1 part of Chlorine.

H_2 O is a compound 2g of hydrogen is chemically combined with 16g of Oxygen.

Chemical bonding is the attractive forces which holds the atoms together in a molecule.

NaCl - the attractive force is called as Ionic bond.

H_2 O - the bond present is a covalent bond

A mixture has two or more elements but there is no chemical bonding present in it. The components of a mixture can be easily separated from it.

Answer from: Quest

Mass is the amount of matter in an object. weight is the measurement of the pull of gravity on an object. say for example, you travel to the moon which has a different gravitational field compared to the gravitational field of earth. (gravitational fields: earth = 1, moon = 0.165) now when you are on the moon, the pull of gravity on you is different than on the earth. and as weight is the measurement of the pull of gravity on an object, that means yes, your weight can and will change on the moon. however, on the moon, on earth or even on jupiter, the amount of mass inside of you remains the same. meaning your physical mass remains constant. in conclusion it is possible for your weight to change as your mass remains constant.
