Answer:

its turgor pressure decreases

Explanation: This is also important because this function regulates water loss within the plant. Lower turgor pressure can mean that the cell has a low water concentration and closing the stomata would help to preserve water. :-)

When a leaf loses much-needed water, its turgor pressure would decrease. Hence Option A is Correct

Turgor Pressure is created in the cells of a leaf when there is enough water. The water stretches the cell membrane outward, creating a kind of pressure.

When the cells lose water, the cell membrane shrinks inward and loses the supporting pressure.

Thus, the turgor pressure created by the presence of water is lost by the absence of water.

The absence of water also affects the rate of photosynthesis and transpiration negatively and not positively. A leaf losing water has no bearing on the atmospheric pressure.

Answer:

Explanation:

To find the number of moles in a substance given it's number of entities we use the formula

[tex]n = \frac{N}{L} \\[/tex]

where n is the number of moles

N is the number of entities

L is the Avogadro's constant which is

6.02 × 10²³ entities

From the question we have

[tex]n = \frac{8.02 \times {10}^{25} }{6.02 \times {10}^{23} } \\ \\ = 1.33 \times {10}^{2} \: \: \: moles[/tex]

Hope this helps you

Answer:

3.329 g

Explanation:

First you need to determine the molar mass of H2S which is 34.1 g/mol.

With that we know that to find the moles of H2S we just divide the mass of sample with the molar mass.

3.54 g / 34.1 g/mol = 0.103812317  mol of H2S

This means that there is also 0.103812317  mol of sulfur since there is 1 mole of sulfur per 1 mole of H2S.

The molar mass of sulfur is 32.065 g/mol and to find the mass of sulfur you need to multiply the molar mass with the moles of the compound.  

0.103812317  mol * 32.065 g/mol = 3.329 g of sulfur

Let me know if you get something else or if something is unclear in the comments so that we can figure it out.

Answer:

CaKr Na2S BaCl3 MgF. CaKr-Kr is a noble gas Na2S-not balanced BaCl3-not balanced MgF-not balanced.

Explanation:

The CaKr is  compound which is likely to form because its charge will be balanced.

A chemical compound is referred to as a substance made up of several similar molecules linked together with chemical bonds and containing atoms from multiple elements. A molecule made up of only one element's atoms is hence not a compound.

It gains charge when electrons are transferred between each other. When the count of protons is higher than the count of electrons, the charge is positive.

Ca has 1 charge and Kr has also 1 charge. hence, CaKr will form as a compound. The charge of  [tex]Na_{2}S, BaCl_{3}[/tex] and MgF is not balanced that's why they can not form compound.

Answer:

The ratio is  [tex]0.67 : 1[/tex]

Explanation:

From the question we are told that

 The activation energy separating the equatorial and the axial form is [tex]\Delta E = 0.24\ kcal/mol[/tex]

 Generally according to the Boltzmann distribution , the relationship between  concentration(in terms of number of molecule) of the equatorial form and  the concentration of the axial form is mathematically represented as

       [tex]N = N_o e^{-\frac{\Delta E }{RT} }[/tex]

Here [tex]N_o[/tex] is the number of molecule in equatorial form and  N is the number of the molecules in the axial form.

   R is the gas constant with value  [tex]R = 1.987 *10^{-3} \ kcal\cdot mol^{-1} \cdot k^{-1}[/tex]

     T is the temperature of the room with value  [tex]T = 25^oC = 298 \ K[/tex]

So

    [tex]\frac{N}{N_o} = e^{-\frac{0.24 }{1.987*10^{-3} * 298} }[/tex]

=> [tex]\frac{N}{N_o} = 0.67[/tex]

So the ratio of the concentration of equatorial form to the axial form is

Answer: boiling point

Explanation:

Answer:

A.) Linear

Explanation:

The geometry of the molecular oxygen (O₂) is linear. Thus, option (A) is correct.

Valence shell electron-pair repulsion theory (VSEPR theory) is used to predict the molecular structure, and bond angles around a central atom of a molecule by using the number of bonds and lone electron pairs in Lewis structure.

The VSEPR model considers that electron pairs present in the valence shell of a central atom have an arrangement so that repulsions between these electron pairs will be minimized by maximizing the distance between them.

The valence electrons of a central atom form either bonding pairs or lone pairs. The electrostatic repulsion of these electrons is minimized when several regions of high electron density maximum possible distance.

The oxygen molecule has linear geometry with a bond angle of 180°. Each oxygen in oxygen molecule has two lone pairs of electrons on it.

DNA contains the commands that an organism requires to develop, survive, and reproduce. DNA sequences must be transformed into messages that can be used to make proteins, which are the complex molecules that do the majority of the work in our bodies, in order to perform these functions.

Deoxyribonucleic acid is a polymer consisting of two polynucleotide chains that coil into one another to form a double helix.

It contains genetic information in the form, fully operational, growth, and reproduction of all kinds of organisms and viruses. Nucleic acids include DNA and ribonucleic acid.

DNA stores information as a code composed of four chemical bases: adenine (A), guanine (G), cytosine (C), and thymine (T).

DNA contains all of the instructions that an organism needs to develop, survive, and reproduce.

Kilograms are the largest unit among the options listed.

The metric system is a decimal-based system of measurement widely used around the world. It provides a standardized and convenient way to express measurements by utilizing prefixes that represent powers of 10.

In the metric system, the base unit for measuring mass is the gram (g). The gram is a relatively small unit, and to express larger or smaller masses, prefixes are added to the base unit. Here are some commonly used metric prefixes for mass.

The largest measurement among the options provided is kilograms (kg). Kilograms are larger units of measurement compared to grams (g), milligrams (mg), and centigrams (cg). The metric system follows a decimal-based system, where each unit is 10 times larger or smaller than the adjacent unit.

1 kilogram (kg) is equal to 1,000 grams (g), 1,000,000 milligrams (mg), and 10,000 centigrams (cg). Therefore, kilograms are the largest unit among the options listed.
