A can of peas and carrots has 2 typed of matter (peas and carrots) that can be separated my physical means. (You can do it with a spoon). Another example= chicken noodle soup, a snickers bar

Explanation:

A mixture is defined as a substance which consists of two or more substances that are physically combined to each other.

For example, when peas and carrots are mixed together then both of them physically combine together.

A mixture can be easily separated by physical means. Whereas substances which are chemically combined to each other leads to formation of new substances.

A chemical substance can only be separated by chemical means.

Hence, a can containing peas and carrots is a mixture.

Some other mixtures are as follows.

Sand in water.

Peas and potatoes.

Onions and carrots.

Stones in a liquid.

If this same quantity of energy were transferred to 2.5 kg of water at it's boiling point what fraction of the water would be va

garik1379 [7]

Answer:

Fraction of water that can be vaporized = 0.0961 or 9.61%

<em>Note : The question is incomplete. The complete question is given below:</em>

<em>A serving of Cheez-Its releases 130 kcal (1 kcal = 4.18 kJ) when digested by your body.</em>

<em>If this same quantity of energy were transferred to 2.5 kg of water at its boiling point, what fraction of the water would be vaporized?</em>

Explanation:

Energy released by a serving of Cheeze-Its = 130 kcal

Since 1 kcal = 4.18 kJ, 130 kcal = 130 * 4.18 kJ = 543.4 kJ

Heat of vaporization (evaporating or condensing) Hv, of water = 2260 J/g

From formula, quantity of heat, Q = mass * heat of vaporization

mass of water = 2.5 kg = 2500 g

Q = 2500 g * 2260 J/g

Q = 5650000 J = 5650 kJ

Therefore 2.5 kg of water requires 5650 kJ of heat for complete vaporization

Fraction of water that can be vaporized by 543.4 kJ energy = 543.4/5650

Fraction of water that can be vaporized = 0.0961 or 9.61%

Determine the mass (in g) of a substance, with a density of 2.26 g/mL, that occupies 350.0 mL.

Andreyy89

Answer:

m = 79.1 grams

Explanation:

Given that,

Density, d = 2.26 g/mL

Volume occupies, V = 35 mL

We need to find the mass of the substance. We know that the density of an object is equal to the mass per unit volume. So,

d = m/V

$m=d\times V\\\\m=2.26\ g/mL\times 35\ mL\\\\m=79.1\ g$

So, the mass of the substance is 79.1 grams.

The process in which an organic acid and an alcohol react to form an ester and water is known as esterification. Ethyl butanoate

Daniel [21]

Answer:

696g

Explanation:

To determine the mass of ethylbutanoate produced, it is important that we know the number of moles of ethylbutanoate produced.

Now from the chemical equation, it can be seen that one mole of ethanol produces one mole of ethylbutanoate. This means that 6.0 mol of ethanol will surely produce 6.0 mol of ethylbutanoate.

Now, we need to get the mass of ethylbutanoate produced. The mass of ethylbutanoate produced is the number of moles of ethylbutanoate produced multiplied by the molar mass of ethylbutanoate produced.

The molar mass of ethylbutanoate is 12(6) + 12(1) + 16(2) = 116g/mol

The mass thus produced is 116 * 6 = 696g

_Al(s) + - 02(g) → _Al2O3 (s)<br> Balance equation

AfilCa [17]

Explanation:

Chemical reaction

When two or more substances react and form some new substance it is called as chemical reaction .

For example :

Al (s) + O₂ (g)----> Al₂O₃(s)

Chemical equation

It is the representation of chemical reaction in terms of symbols ,molecular formulas ,moles , states etc .

As we know all chemical reaction obeys law of chemical combination therefore chemical reaction need to be balanced .

Law of conservation of mass

Mass can neither be created nor be destroyed in a chemical reaction , it is always conserved .That is why reactions need to be balanced .

Let us balance

Al (s) + O₂ (g)----> Al₂O₃(s)

After balancing , it becomes :

2Al (s) + 3/2O₂ (g)----> Al₂O₃(s)
