D. 1 = gamma; 2 = alpha, 3 = beta

Explanation:

I apologize if this answer is late, but I got answered the question right on my "Types of Radioactive Decay" quiz :)

Hope this is helpful for others! :D

Based on the table, the type of radiation belong from 1 is the gamma rays, from 2 is the aplha rays and from 3 is the beta rays.

During the radioactive decay process, some amount of energy is released in the form of particles and that radiations will known as alpha rays, beta rays and gamma rays.

Hence 1 is the gamma rays, 2 is the aplha rays and 3 is the beta rays.

Why does a car rust from road salt? Metal parts of a car come in contact with precipitation water containing carbon dioxide and oxygen. Road salt contains free-radical ions and they come into contact with the precipitation water. After extended exposure to oxygen, iron oxide forms, which speeds up the rusting process.

Answer:

Mass of Oxygen is equal to 0.005566 grams

Explanation:

As we know,

ppm=(grams of solute/grams of solution)*1,000,000

Substituting the given values, we get -

23 ppm = (grams of solute/242.0066 grams)*1,000,000

1 ml = 1 gram

On solving the above equation, we get -

grams of solute = (23 * 242.0066)/1,000,000

= 0.005566 grams

Mass of Oxygen is equal to 0.005566 grams

Explanation:

A double displacement reaction is one in which exchange of ions take place. The salts which are soluble in water are designated by symbol (aq) and those which are insoluble in water and remain in solid form are represented by (s) after their chemical formulas.  

A double displacement reaction in which one of the product is formed as a solid is called as precipitation reaction.  

The balanced chemical equation is:

Answer:

it's B(Energy source,conductor and receiver)

Answer:b

Explanation:

The function of the outer covering of a plant is to help reduce water loss, option B. The outer covering of a plant is known as the epidermis, and it serves as a protective layer that helps to prevent excessive water loss through transpiration.

The epidermis may  contain specialized structures such as stomata and trichomes, which further regulate water loss and protect the plant from environmental stresses such as insect predation and UV radiation.

Option A, "A plant's outer covering is involved in reproduction," is incorrect because the reproductive structures of plants are typically located within the plant's interior, not on the outer surface.

Option C, "A plant's outer covering is for preying on other plants," is incorrect because plants are not capable of actively preying on other plants.

Option D, "A plant does not have an outer covering," is incorrect because all plants have an outer covering in the form of the epidermis or a similar structure.

Hence, option B is correct.

Answer:

45 mL

Explanation:

Tenemos los siguientes datos:

V = 1 L

C = 4,5% v/v

El porcentaje en volumen (%v/v) expresa el volumen de soluto (alcohol en este caso) que hay cada 100 mL de solución. Si la solución tiene una concentración del 4,5% v/v eso quiere decir que hay 4,5 ml de alcohol cada 100 ml de solución, de acuerdo a lo siguiente:

4,5% v/v alcohol = volumen alcohol/ volumen solución x 100 = 4,5 mL alcohol/100 mL solución= 4,5 mL alcohol/0,1 L alcohol

Por lo tanto, al multiplicar por el volumen total de la solución (1 L), obtenemos la cantidad total de alcohol:

4,5 mL alcohol/0,1 L alcohol x 1 L = 45 mL

Answer:

The theoretical yield of ammonia is 15 g.

Explanation:

The statements are:

2.8g of hydrogen are left over.

Hydrogen is the excess reactant.

Nitrogen is the limiting reactant.

The theoretical yield of ammonia is 15 g.

To solve this question we must find the moles of each reactant. Thus, we can find the limiting reactant. With limitinf reactant we can find the theoretical yield and the amount in excess of the reactant that is in excess:

Moles Nitrogen -28g/mol-

10.0g * (1mol / 28g) = 0.357 moles

Moles hydrogen -2g/mol-

5.0g * (1mol / 2g) = 2.5 moles

For a complete reaction of 0.357 moles of nitrogen are required:

0.357mol N2 * (3mol H2 / 1molN2) = 1.071 moles hydrogen.

As there are 2.5 moles of hydrogen, hydrogen is the excess reactant and nitrogen is the limiting reactant

The moles of hydrogen that are left over are:

2.5moles - 1.071moles = 1.429moles Hydrogen

The mass is:

1.429moles Hydrogen * (2g / mol) = 2.8g of hydrogen are left over

The moles of ammonia produced are:

0.357mol N2 * (2mol NH3 / 1molN2) = 0.714 moles of ammonia are produced (Theoretical moles)

The theoretical mass is (Molar mass NH3 = 17g/mol):

0.714 moles of ammonia * (17g / mol) =

12g of ammonia is the theoretical mass

The false statement is:

The false statement, when 10 g of nitrogen reacts with 5.0 g of hydrogen to produce ammonia is that the theoretical yield of ammonia is 15g.

Moles of any substance will be calculated as:

n = W/M, where

W = given mass

M = molar mass

Given chemical reaction is:
N₂(g) + 3 H₂(g) → 2 NH₃(g)

Moles of 10g of N₂ = 10/28 = 0.357 moles

Moles of 5g of H₂ = 5/2 = 2.5 moles

From the stoichiometry of the reaction:

1 mole of N₂ = react with 3 moles of H₂

0.357 moles of N₂ = react with 3×0.357=1.071 moles of H₂

Here nitrogen is the limiting reactant and hydrogen is excess reactant, and formation of ammonia depends on the limiting reactant.

1 mole of N₂ = react with 2 moles of NH₃

0.357 moles of N₂ = react with 2×0.357=0.714 moles of NH₃

Now we calculate the mass of ammonia from the given moles as:

M = (0.714) (17) = 12 g.

Hence, the false statement is that theoretical yield of ammonia is 15g.
