Answer:
The answer would be C) a liquid.
Explanation:
If you were to pour a glass of water into a rectangular container, the water would fill up the container and be in the same shape as the container. That is becuase water flows and it doesn't harden up or take its own shape until it's frozen. The molecules are not tightly secure to each other so they are able to move freely.
Answer:
d. compound
Explanation:
<u>Mixture </u>: It is defined as the substance that is made by the combination of two or more different components which are physically combined.
<u>Homogeneous mixture</u> are the mixtures in which the composition of the substances in it are uniformly mixed. <u>Heterogeneous mixture</u> are the mixtures in which the composition of the substances in it are not uniformly mixed.
<u>
Compound :</u> It is a pure substance which is made from atoms of different elements combined together in a fixed ratio by mass and are chemically bonded.
<u>
Element :</u> It is a pure substance which is composed of atoms of similar elements.
<u>As discussed above, The different elements in the compounds are chemically bonded and hence, it is the substance which can be broken down into the simpler units when it subtend only by the chemical change.</u>
The answers would be the mass before a reaction is the same as the mass after a reaction which basically means mass is conserved
