The element X has three naturally occurring isotopes. The masses (amu) and % abundance of the isotopes are given in the table below. The average atomic mass is ______amu. Give your answer two decimal places.

Answers

Answer:

In order to solve for this you would need to plug it into an equation. You would add them all up to eachother after multiplying them by their percentages.

So it would be (0.75*48.90)+(0.18*49.10)+(0.07*50.20). Plug it all into a calculator and you get 49.027amu. Then you would round to significant figures so 49.03amu should be your answer.

What is the theoretical yield of carbon dioxide? 0. 993 g 2. 98 g 3. 65 g 8. 93 g.

Answers

Answer:

The answer is C.

Explanation:

i got a 100 on the test

The theoretical yield of carbon dioxide, CO₂ obtained from the reaction is 8.93 g

We'll begin by calculating the mass of citric acid, H₃C₆H₅O₇ that reacted and the mass of carbon dioxide, CO₂ produced from the balanced equation.

H₃C₆H₅O₇ + 3NaHCO₃ —> 3CO₂ + 3H₂O + Na₃C₆H₅O₇

Molar mass of H₃C₆H₅O₇ = (3×1) + (12×6) + (5×1) + (7×16) = 192 g/mol

Mass of H₃C₆H₅O₇ from the balanced equation = 1 × 192 = 192 g

Molar mass of CO₂ = 12 + (2 × 16) = 44 g/mol

Mass of CO₂ from the balanced equation = 3 × 44 = 132 g

From the balanced equation above,

192 g of H₃C₆H₅O₇ reacted to produce 132 g of CO₂

Finally, we shall determine the theoretical yield of CO₂. This can be obtained as follow:

From the balanced equation above,

192 g of H₃C₆H₅O₇ reacted to produce 132 g of CO₂.

Therefore,

13 g of H₃C₆H₅O₇ will react to produce = (13 × 132) / 192 = 8.93 g of CO₂.

Thus, the theoretical yield of CO₂ is 8.93 g

do you think organisms who live in the artic would survive in the desert? Do you think organisms in the desert would survive in the artic? Why or why not?

Answers

Answer:

I'd say probably not

Explanation:

Organisms have evolved to survive and thrive in particular environmental conditions, specifically focusing on food supply, temperature, terrain, etc.. Therefore, desert animals would not be equipped with the insulation to survive in cold climates like the artic, and would freeze to death, and artic animals would most likely die from heat exhaustion in the desert. Additionally, fish, which is a main food source for articles animals, are not available in the desert, and it's the same case for desert animals in the artic. Finally, those organisms' enzymes and proteins, which make up their being and are the reason they can function, are only optimal in the temperature range in which they normally live; therefore, switching to such drastically different climate would result in their enzymes denaturing and their cell and eventual organism death.

Explanation:

Excess Na2SO4 (aq) is added to a 42.53 mL sample of Ba(NO3)2(aq).

1. What is the formula of the precipitate?
The formula for the precipitate is 2Na(NO3)(aq).

2. If 3.046 grams of precipitate was formed, what was the molarity of the Ba(NO3)2(aq)?

Answers

1. The formula of the precipitate formed is Ba₂SO₄(s)

2. The molarity of the Ba(NO₃)₂ solution is 0.188 M

1. Determination of the formula of the precipitate formed.

We'll begin by writing the net ionic equation for the reaction between Na₂SO₄ and Ba(NO₃)₂. This is given below:

Na₂SO₄(aq) + Ba(NO₃)₂(aq) —>

2Na⁺(aq) + SO₄²¯(aq) + Ba²⁺(aq) + 2NO₃¯(aq) —> Ba₂SO₄(s) + 2Na⁺(aq) + 2NO₃¯(aq)

Cancel the spectator ions (i.e Na⁺ and NO₃¯) to obtain the net ionic equation

SO₄²¯(aq) + Ba²⁺(aq) —> Ba₂SO₄(s)

Therefore, the formula of the precipitate formed is Ba₂SO₄(s)

2. Determination of the molarity of Ba(NO₃)₂

We'll begin by calculating the number of mole of in 3.046 g of precipitate, Ba₂SO₄

Molar mass of Ba₂SO₄ = (2×137) + 32 + (4×16) = 370 g/mol

Mass of Ba₂SO₄ = 3.046 g

Mole of Ba₂SO₄ =?

Mole = mass /molar mass

Mole of Ba₂SO₄ = 3.046 / 370

Mole of Ba₂SO₄ = 0.008 mole

Next, we shall determine the number of mole of Ba(NO₃)₂ required to produce 0.008 mole of Ba₂SO₄

Na₂SO₄(aq) + Ba(NO₃)₂(aq) —> Ba₂SO₄(s) + 2NaNO₃(aq)

From the balanced equation above,

1 mole of Ba(NO₃)₂ reacted to produce 1 mole Ba₂SO₄.

Therefore,

0.008 mole of Ba(NO₃)₂ will also react to produce 0.008 mole of Ba₂SO₄

Thus, 0.008 mole of Ba(NO₃)₂ is required for the reaction.

Finally, we shall determine the molarity of the Ba(NO₃)₂ solution

Mole of Ba(NO₃)₂ = 0.008 mole

Volume = 42.53 mL = 42.53 / 1000 = 0.04253 L

Molarity of Ba(NO₃)₂ =?

Molarity = mole / Volume

Molarity of Ba(NO₃)₂ = 0.008 / 0.04253

Molarity of Ba(NO₃)₂ = 0.188 M

1 mole of H₂O has more molecules than other compounds. The correct option is A.

What are molecules?

A molecule is a collection of two or more atoms held together by attractive forces known as chemical bonds.

The International System of Units uses the mole as the unit of material quantity. How many elementary entities of a specific substance are present in an object or sample is determined by its quantity.

The tiniest component of any substance is capable of existing independently while maintaining its chemical and physical properties and is composed of one or more elements.

Out of these molecules, water has more molecules than  1 mole Al(OH)₃ and 1 mole NaCl. They don't have the same number of moles.

Therefore, the correct option is A. 1 mole H₂O.
