Answer:
Formed by adding 5 g of sugar to 1 L of water
Explanation:
The substance formed by adding 5 g of suagr to 1 L of water is a mixture.
<em>A mixture is defined as two or more substances that are physically mixed but do not react together. It thus means that the component substances of a mixture can be retrieved through appropriate means of separations.</em>
<u>A mixture of sugar and water can be separated by evaporation. The mixture is heated and the vapor from the boiling water can be condensed to retrieve the water while the residue will give the sugar that was initially dissolved in it. </u>
The products formed from other descriptions in the illustration cannot be separated ordinarily and thus, are not considered to be mixture. The components have been chemically combined together.
Answer:
Explanation:
<u>Given reaction is:</u>
3X + 2Y → 5C + 4D
<u>In this reaction, we have:</u>
For 3 moles of X, 4 moles of D
So,
4D = 3X
Divide both sides by 4
D = 3X/4
Multiply both sides by 21
21D = 3X/4 × 21
21D = 3*21X/4
21D = 63X/4
21D = 15.75X
So, to produce 21 moles of D, we need 15.75 moles of X.

the conversion would be 0.00225 mole
First convert grams to moles:
90.0g *(mole/39.997) = 2.250mole
Remember that molarity is moles per liters:
2.250mol/3L = .750 M
