PLEASEEE HELPP AND ANSWER FAST!!

1.Water is an example of a mixture because it is made up of hydrogen oxygen Adams bonded together
True or false
2. Which of these methods could be used to separate an insoluble solid from a soluble solid?
A) Multi in the mixture and then using a filter to separate out the soluble solid
B) melting the Mctier mixing it with water and then using a magnet to separate out the insoluble solid
C) mixing the mixture with water and then using chromatography to separate the two dissolved solids
D) mixing the mixer with water filtering out the insoluble solid and then evaporating the water to isolate the soluble water
3. Which of the following correctly describes a mixture?
A) The particles are chemically bonded together, and they retain their individual physical and chemical properties
B) The particles are not chemically bonded, and they can only come by and in certain set ratios
C) The particles do not retain their individual chemical properties, and they can only be separated by chemical means
D) The particles have no set ratio for how to combine, and they can be separated by physical means

Answer 1

1. False

2. D

3. D

Step-by-step explanation:

1. Water is not a mixture because a mixture is a substance that is made up of two or more different substance each with their unique characteristics.

2. In order to separate an insoluble solid from a soluble solid, just add water to the mixture and the soluble solid will dissolve. Filter off the insoluble solid and dry the residue. To recover the soluble solid, evaporate off the water using a suitable method.

3. A mixture is a combination of two or more substances that are not chemically combined with each other and can be separated by physical means.

Answer 2

1. Water is an example of a mixture because it is made up of hydrogen oxygen Adams bonded together ?

Answer:

• False

Explanation

• Water is a Compound.
• Mixture refers to the physical combination of two or more substances in any proportion on which the identities are retained and are mixed in the form of solutions, suspensions, and colloids.
• A Compound is a chemical combination of two or more substances in fixed ratio. If we combine 3 parts of Hydrogen and 1 part of oxygen, we will never get water.

2. Which of these methods could be used to separate an insoluble solid from a soluble solid?

Answer:

D. Mixing the mixer with water filtering out the insoluble solid and then evaporating the water to isolate the soluble water.

3. Which of the following correctly describes a mixture?

D. The particles have no set ratio for how to combine, and they can be separated by physical means.

Explanation:

1. In mixture , there is no specific ratio, in mixture, you have to mixed the two or more substances in any proportion.
2. They have no chemical formula.
3. They retain original properties.
4. Can be recovered by physical means
