Mass
Magnetism
Shape
Volume

Answers

Answer 1

Answer:

I believe its A. Mass

Explanation:

An intensive property is a property of matter that depends only on the type of matter in a sample and not on the amount. For example, the electrical conductivity of a pure substance is a property that depends only on the type of substance. Silver, gold, and copper are excellent conductors of electricity, while glass and plastic are poor conductors.. Other intensive properties include color, temperature, density, and solubility.

Which statement best explains what happens to a leaf when it has lost much-needed water?

Answers

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

What is Turgor pressure ?

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.

Compared to ionic compounds, molecular compounds generally have

A. good conductivity.
B. greater densities.
C. more chemical bonds.
D. a low boiling point.

Answers

D.A low boiling point

Compared to ionic compounds, molecular compounds generally have a low boiling point and the correct option is option D.

What are Molecular compounds?

Molecular compounds are held together by covalent bonds. They are also called covalent compounds.

Covalent bonds are responsible for many of the properties of covalent compounds. Covalent compounds have relatively low boiling points, cannot conduct electricity, and may not dissolve in water.

Unlike ionic compounds, covalent compounds do not have freely moving electrons, so they cannot conduct electricity.

The individual molecules of covalent compounds are more easily separated than the ions in a crystal, so most covalent compounds have relatively low boiling points.

Therefore, compared to ionic compounds, molecular compounds generally have a low boiling point and the correct option is option D.

How many grams of sulfur are in 3.54 g of H2S?

Answers

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

Explanation:

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

What is compound?

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.

What is charge?

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.

What is VSEPR theory?

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.

1. The thermal interconversion of the axial and equatorial substitutents of the chair conformation of cyclohexane is extremely slow because the two forms are separated by a relatively high activation energy barrier, 10.5 kcal/mol (3672 cm−1). With CN substituents, the equatorial form is only 0.24 kcal/mol (84 cm−1) lower in energy than the axial form. Show how you would determine the ratio between the concentrations of the equatorial and axial forms using the Boltzmann distribution.

Answers

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

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.

How many moles of water are produced when 5 moles of hydrogen gas react with 2 moles of oxygen gas?

a. 2 moles of water
b. 4 moles of water
c. 5 moles of water
d. 7 moles of water

Answers

Answer:

It is b

Explanation: I did it on the test and got it right

The moles of water are produced when 5 moles of hydrogen gas react with 2 moles of oxygen gas - b. 4 moles of water

The stoichiometric coefficients can be considered in a balanced equation as moles of reactants needed or moles of products formed in the reaction.  

In the given case, the balanced chemical equation for this synthesis reaction looks like this

2H2 + O2 → 2H2O  

from the balanced equation, it is clear that the 2  moles of hydrogen gas and 1  mole of oxygen gas are required to produce  2  moles of water.  so it means that the reaction produces twice as many moles of water as you have moles of oxygen gas that take part in the reaction and the same moles as hydrogen atoms present.Here it is given that there are only 2 moles of oxygen which means it is in deficiency however, it will produce 4 moles of water with four moles of hydrogen.

Thus, the moles of water are produced when 5 moles of hydrogen gas react with 2 moles of oxygen gas - b. 4 moles of water
