Answer:

Yes, we can separate the liquids from solutions using distillation.

Explanation:

In distillation, the components or substances are separated from a liquid mixture by selective boiling and condensation. Distillation can result in substantially complete separation (near-pure components), or it can be a partial separation that increases the concentration of the selected components in the mixture. In both cases, the process takes advantage of the differences in the relative volatility of the components of the mix. In industrial chemistry, distillation is a unitary process of universal practical importance, but it is a process of physical separation, not a chemical reaction. Distillation is also be used to separate a solution from two or more liquids or fractions. They are called miscible liquids and must have different boiling points, e.g. B. ethanol and water or fermented fruit juice. A capacitor is used. A mixture is heated to just above 80 degrees Celsius (the boiling point of ethanol is 79 degrees Celsius). Ethanol evaporates and condenses. It can be collected in a cup. The water remains in the balloon.

How many moles are in 29.5 grams of Ax?
JulsSmile [24]

The number of moles present in 29.5 grams of argon is 0.74 mole.

The atomic mass of argon is given as;

Ar = 39.95 g/mole

The number of moles present in 29.5 grams of argon is calculated as follows;

39.95 g ------------------------------- 1 mole

29.5 g ------------------------------ ?

= \frac{29.5}{39.95} \\\\= 0.74 \ mole

Thus, the number of moles present in 29.5 grams of argon is 0.74 mole.

Answer the following questions based on the reaction below: NaOH(aq) + KHP(s) --&gt; NaKP(aq)+H2O(I)
Natali [406]

Answer:

<u />

  • <u>a) 1.44g</u>

<u />

  • <u>b) 77.3%</u>

<u />

Explanation:

<u>1. Chemical balanced equation (given)</u>

       NaOH(aq)+ KHP(s)\rightarrow NaKP(aq)+H_2O(l)

<u>2. Mole ratio</u>

1molNaOH(aq):1molKHP(s)

This is, 1 mol of NaOH will reacts with 1 mol of KHP.

<u />

<u>3. Find the number of moles in 72.14 mL of the base</u>

    Molarity=\text{number of moles of solute}/\text{volume of solution in liters}

    \text{Volume of solution}=72.14mL=0.07214liters

     \text{Number of moles of NaOH}=0.0978M\times 0.07214liter=0.007055mol

<u>4. Find the number of grams of KHP that reacted</u>

The number of moles of KHP that reacted is equal to the number of moles of NaOH, 0.007055 mol

Convert moles to grams:

  • mass = number moles × molar mass = 0.007055mol × 204.23g/mol
  • mass = 1.4408 g.

You have to round to 3 significant figures: 1.44 g (because the molarity is given with 3 significant figures).

<u>5. Find the percentage of KHP in the sample</u>

The percentage is how much of the substance is in 100 parts of the sample.

The formula is:

  • % = (mass of substance / mass of sample) × 100

  • % = (1.4408g/ 1.864g) × 100 = 77.3%

Answer:

Some of the physical and chemical properties of magnesium are:

-The term ‘magnesium’ is derived from the Greek word magnesia, which refers to the name of the place from where it was extracted.

-Magnesium is closely related to manganese and magnetite.

-About 2.1% of the Earth’s crust contains magnesium. This makes magnesium the 6th most found element.

-The biggest deposits of magnesium is found in the seawater. It has been calculated by scientists that a cubic mile of seawater contains about 6 million tons of this element

2nd answer:

Physical Properties of Magnesium: ”I’m a highly stable element, so you can count on me”

Chemical Properties of Magnesium: ”I love to travel but I do corrode aluminum so we won’t be flying off on adventures in airplanes planes anytime soon
