Answer:

KNO3 (Potassium Nitrate)

Explanation:

I just know.

Answer:

Limiting: Lab covers. Books produced: 75. Excess amounts: In explanation

Explanation:

Amount that can be produced with just lab covers: 75 books (150/2)

Amount that can be produced with just lined paper: 150 books (7500/50)

Amount that can be produced with graph paper: 120 (3000/25)

Amount that can be produced with staples: Approximately 83 (250/3)

As we can see, the lab covers are limiting as they can only produce 75 books. So, we can only make 75 books.

You will have 3,750 lined paper left over (or 75 books)

(150-75=75 , 75*50=3,750)

You will have 1,125 graph paper left over (or 45 books)

(120-75=45 , 75*25=1,875 , 3000-1875=1125)

And then you will have approximately 25 staples left over (or 8 books)

(83-75=8 , 8*3=225, 250-225=25)

(Hopefully this is correct, I apologize if I messed up)

Answer:

all organisms in the jungle

Explanation:

Scientists are studying cellular respiration in a jungle ecosystem that has plants, animals and decomposers, so all organisms in the jungle carry out cellular respiration.

Cellular respiration is a process in which organism use the oxygen molecule for the conversion of their food materials to get the chemical energy by the product of water and carbon dioxide.

This respiration process is done by all living organism like plants, animals, insects, bacteria, etc. to get energy for the other cellular functions. So, in the ecosystem of jungle plants, animals and decomposers all will perform cellular respiration.

Hence, option (c) is correct i.e. all organisms in the jungle.

Potassium is an element, with the symbol K

Explanation:

An element is something that cannot be broken down any further, for example, calcium, its Ca.

A compound is when you bond two or more elements. Compounds can be broken down into its original elements, for example, H₂O, it contains two atoms of hydrogen and one atom of oxygen (both hydrogen and oxygen are elements).

Explanation:

Silver has a molar mass of 107.87 g⋅mol−1 . What does this mean? It means that if I have such a mass of silver, there are Avogadro's number, NA=6.022×1023 , individual silver atoms

The number of silver atoms in 1 mole of silver. Avogadro's constant is

defined as the number of units in one mole of a substance.

Avogadro's constant is denoted by the following below:

NA = 6.022×10²³ mol⁻¹.

In the question, we were asked for the number of silver atoms in 1 mole of a

substance which is equivalent to the Avogadro's constant.

This means the number of atoms in 1 mole of silver = 6.022×10²³ mol⁻¹.

Explanation:

Answer:

The answer is D. The rate of the forward reaction is greater than the rate of the reverse reaction.

Explanation:

The forward reaction rate was greater than the reverse reaction rate because more product is present at time 2. This is the answer from ap classroom.

The given reaction has been inferred the increased rate of forward reaction than reverse reaction. Thus, option D is correct.

The chemical reaction has been given by the combination of reactants for the formation of product. The reactants combine in the fixed proportion to form the product.

The rate of reaction has been defined as the rate of formation of product or the disappearance of reactants.

The forward reaction has been given as the rate of formation of product. The reverse reaction has been given as the rate of dissociation of product.

In the given condition, the number of reactant at time 1 are more than the reactant at time 2. This states that there has been increased formation of the product at time 2.

Thus, the given reaction has been inferred the increased rate of forward reaction than reverse reaction. Thus, option D is correct.

Answer:

1.0625 g

Explanation:

Number of moles in 5g of NH4NO3 = 5.0g/80g/mol = 0.0625 moles

Again the balanced reaction equation is;

NH3 + HNO3 → NH4NO3

So,

1 mole of NH3 yields 1 mole of NH4NO3

x moles of NH3 yields 0.0625 moles of NH4NO3

x = 0.0625 moles of NH3

Mass of NH3 = number of moles * molar mass

Mass of NH3 = 0.0625 moles * 17g/mol

Mass of NH3 = 1.0625 g
