Answer:

2

Explanation:

The number of atoms of hydrogen that are present after the reaction is 4. The correct option is the first option - 4

From the question,

We are to determine the number of atoms of hydrogen present after the reaction.

From the law of conservation of mass which states that

"Matter can neither be created nor destroyed"

This means, the number of atoms are the same before and after the chemical reaction.

Since the number of hydrogen atoms before the reaction is four, then there would be four hydrogen atoms after the reaction.

Hence, the number of atoms of hydrogen that are present after the reaction is 4. The correct option is the first option - 4

Answer:

In the first law, an object will not change its motion unless a force acts on it. In the second law, the force on an object is equal to its mass times its acceleration. In the third law, when two objects interact, they apply forces to each other of equal magnitude and opposite direction.

1. Bacteria reproduce through binary fission (already filled in)

2. A parent bacterial cell is able to survive in the presence of antibiotic penicillin. Subsequent generations from this parent will be resistant to penicillin

3. Something that potatoes and bacteria have in common is that they both reproduce through asexual reproduction.

4. In asexual reproduction DNA from the parent cell replicates before it produces daughter cells.

5. Asexual reproduction is a simpler process than sexual reproduction.

To prepare 250 mL of a D10/NS solution using D10W and a vial of NaCl 4 mEq/mL, you would need 9.6 mL of NaCl. Normal saline (NS) contains 154 mEq/L of sodium chloride (NaCl). To prepare 250 mL of NS, you would need 250 mL * (154 mEq/L) = 38500 mEq of NaCl. Since the vial of NaCl contains 4 mEq/mL, you would need 38500 mEq / (4 mEq/mL) = 9625 mL = 9.6 mL of NaCl. So the correct answer is b. 9.6ml.

According to mole concept, there are 368.928 g  mass in 4.2 moles of FeO₂.

Mole is defined as the unit of amount of substance . It is the quantity measure of amount of substance of how many elementary particles are present in a given substance.

It is defined as exactly 6.022×10²³ elementary entities. The elementary entity can be a molecule, atom ion depending on the type of substance. Amount of elementary entities in a mole is called as Avogadro's number.

It is widely used in chemistry as a suitable way for expressing amounts of reactants and products.For the practical purposes, mass of one mole of compound in grams is approximately equal to mass of one molecule of compound measured in Daltons. Molar mass has units of gram per mole . In case of molecules, where molar mass  in grams present in one mole  of atoms is its atomic mass.

Number of moles=mass/molar mass

Thus, mass=4.2×87.84=368.928 g.

Thus, there are 368.928 g  mass in 4.2 moles of FeO₂.

Answer:CH4(g) + 2O2(g) →2H2O(l) + CO2(g)

Explanation: CH4 is dioxide and water. So basically whats happening here is that CH4 is being burned down

Since hydrocarbon fuels only contain two elements, we always obtain the same two products when they burn.

Answer:

CH4(g) + 2O2(g) →2H2O(l) + CO2(g)

Mostly decaying organisms are needed to present in marine mud to form fossil fuels.

Explanation: When organisms and plants died and sank to the bottom of swamps and oceans, brown soil-like materials called peat are formed. Over millions of years, the peat became covered with sand, clay and other minerals and the peat is converted into layers of sedimentary rocks. After a long time, different type of fossil fuels are formed.

Well, if you analyze the text you have transcribed, there appear to be the letters "d", "e", "e", "z", plus, "n", "u", "t", "s."

Assuming you were to combine all of these letters together, the revised text would look as follows:

"Deez nuzts."

However, things are not that simple. Why, you may ask?

Because there is something missing in this transcript.

I believe an additional "your mom" would need to be added.

This results in the final transcript,

"Your mom loves deez nuzts."

But wait! We're not done yet.

This is because this sentence is wordy, and hard to read. It undermines the writer's message and the word choice is bland. Grammarly's cutting edge technology helps you craft compelling, understandable writing that makes an impact on your reader. Much better.
