Answer:

Cohesion

Explanation:

D. you're welcome

One of water's most distinctive properties is cohesion—that is, the tendency of water molecules to "stick" to one another. In plants, this cohesion results in columns of water that stretch through the plant's xylem (the vascular tissue responsible for the transport of water), from the roots all the way to the leaves.

Explanation:

List Known Values-

35N

4M

Formula-

W=FJ

Substitution-

W= 3.5N (4m)

Answer & Units-

140 N

Bobby perform in pushing a 35 N crate a distance of 4 meters the work done by him is 140 joules per second.

The work is something which need energy to be done it can be any physical or chemical energy that can be calculated with the help of Newton law.

Work is calculated by multiplying the force required for the work  by the amount of movement of substance or object.

                    W = F × d   here, W = work

                                                  F = force

                                                  d = distance

Substituting the value in the formula,

                     W = 35 × 4  

                      W = 140 joules

Newton-meter is the same thing as a joule so the unit is joules.

Therefore, bobby perform in pushing a 35 N crate a distance of 4 meters the work done by him is 140 joules per second.

Answer:

The correct option is (c).

Explanation:

Given that,

Mass of iron, m = 3 kg = 3000 g

The temperature of ice increases from 20° C to 25°C.

The specific heat of iron is 0.45 J/g°C

We need to find the energy required to raise the temperature. The formula is given by :

[tex]Q=mc\Delta T\\\\Q=3000\times 0.45\times (25-20)\\\\Q=6750\ J[/tex]

So, 6750 J of energy is required to raise the temperature or iron.

Answer:

2 g/cm3

Explanation:

Density is a measure of a substance's mass over its volume.

Trail Mix

Explanation:

The best description for the snack that Ben is eating would be Trail Mix. This is a very common snack for hikers, hence the name, since it is very healthy and great for taking on hikes since it does not get affected by the sun. This snack was originally called GORP which stands for "good old raisins and peanuts" because the snack originally contained only raisins and peanuts. It has since changed to include various different ingredients such as a variety of nuts, chocolate pieces, dried fruit, cereal etc.

Answer:

0.182 moles of CO₂ are produced by this combustion

Explanation:

First of all, we state the combustion reaction:

C₃H₈  +  5O₂  → 3CO₂  +  4H₂O

As we do not have data from the oxygen, we assume it as the excess reactant. Let's determine the moles of propane, by the Ideal Gases Law.

We convert pressure from Pa to atm

67200 Pa . 1 atm /101300 Pa = 0.663 atm

P . V = n . R . T

0.633 atm . 2.33L = n . 0.082 . 297K

(0.633 atm . 2.33L) / (0.082 . 297K) = n

n = 0.0606  moles

Now we analyse the stoichiometry. Ratio is 1:3.

1 mol of propane can produce 3 moles of carbon dioxide

Then, 0.0606 moles of propane may produce (0.0606 . 3) /1 = 0.182 moles

In conclussion, 0.182 moles of CO₂ are produced by this combustion

P1 = 300 torr

V1 = 50 mL

P2 = 150 torr

V2 = ?

applying Boyle's Law

P1 * V1 = P2 * V2

300 torr * 50 mL = 150 torr * V2

V2 = 300 torr * 50 mL / 150 torr

V2 = 100 mL

Answer:

1 mole of magnesium are required to react with 2.0 mol of hydrochloric acid.

Explanation:

The balanced reaction is:

Mg + 2 HCl → MgCl₂ + H₂

The law of conservation of matter states that since no atom can be created or destroyed in a chemical reaction, the number of atoms that are present in the reagents has to be equal to the number of atoms present in the products. That is, the law of conservation of mass implies that the sum total of charges before and after the chemical reaction remains constant.

The relationships between the quantities of reactants consumed and products formed depend directly on this conservation law, and therefore can be determined by an equation that describes them. This equality is called the stoichiometric equation.

In this case, by stoichiometry of the reaction (that is, the relationship between the amount of reagents and products in a chemical reaction), you have:

Then, 1 mole of magnesium are required to react with 2.0 mol of hydrochloric acid.

Answer:

1 mole of magnesium, Mg

Explanation:

The balanced equation for the reaction is given below:

Mg + 2HCl —> MgCl₂ + H₂

From the balanced equation above,

We can see clearly that 1 mole of Mg requires 2 moles of HCl.

Thus, 1 mole of magnesium, Mg is needed for the reaction.

Answer:

34176.5 torr

Explanation:

It is given that :

Initial pressure, [tex]$P_1 = 830$[/tex] torr

Initial volume, [tex]$V_1 = 650 \ cm^3$[/tex]

Initial temperature,   [tex]$T_1 = 85^\circ C$[/tex]

Final volume,  [tex]$V_2 = 65 \ cm^3$[/tex]

Final temperature,   [tex]$T_2 = 350^\circ C$[/tex]

Therefore, using the combined gas laws, we can write :

[tex]$\frac{P_1V_1}{T_1}=\frac{P_2V_2}{T_2}$[/tex]

Substituting the values, we get

[tex]$\frac{830 \times 650}{85}=\frac{P_2\times 65}{350}$[/tex]

[tex]$P_2 = \frac{830 \times 650 \times 350}{85 \times 65}$[/tex]

    = 34176.5 torr

So the new pressure is 34176.5 torr.

Answer:

The sugar in DNA is deoxyribose. ... Nucleotides in DNA contain four different nitrogenous bases: Thymine, Cytosine, Adenine, or Guanine. There are two groups of bases: Pyrimidines: Cytosine and Thymine each have a single six-member ring.

Adenine, Cytosine, Thymine, and Guanine are the four nucleotides that make up DNA. The four nucleotides have different base structures, but they are all composed of a nitrogenous base, a deoxyribose sugar, and a phosphate group.

Nucleotides are organic compounds made up of a phosphate and a nucleoside. They function as monomeric units of the deoxyribonucleic acid and ribonucleic acid polymers, which are both crucial macromolecules for all kinds of life on Earth.

Adenine, Cytosine, Thymine, and Guanine are the four nucleotides that make up DNA. The four nucleotides have different base structures, but they are all composed of a nitrogenous base, a deoxyribose sugar, and a phosphate group.

The quantity of phosphate residues that a nucleotide has determined its name. Adenosine triphosphate, for instance, is the name of a nucleotide that consists of an adenine base and three phosphate residues (ATP). Adenosine diphosphate would be the nucleotide if it has two phosphates (ADP).

Thus, Adenine, Cytosine, Thymine, and Guanine are the four nucleotides that make up DNA.
