What kind of interaction
(attraction/repulsion) will happen
between the core electrons and the
valence electrons?

Answers

Answer 1
The balance between attractive and repulsive forces results in shielding. The orbital (n) and subshell (ml) define how close an electron can approach the nucleus. The ability of an electron to get close to the nucleus is penetration.

A mixture of hydrogen, nitrogen, and water vapor has a total pressure of 864 mmHg. The partial pressure of hydrogen is 220 mmHg and that of nitrogen is 410 mmHg. What is the partial pressure of water vapor?

Answers

Answer:

As per Dalton's law of Partial pressure,

The total pressure of a mixture of gases is equal to sum of partial pressure of individual components of the mixture.

So,P=P_H+P_N+P_WP=P  

H

+P  

N

+P  

W

 

\implies 864\ mm=220\ mm+410\ mm+P_W\implies⟹864 mm=220 mm+410 mm+P  

W

⟹ P_W=864-630=234P  

W

=864−630=234 mm of Hg.

Explanation:

"The partial pressure of water vapor is 234 mm Hg."

What is partial pressure?

The force that a gas exerts is known as partial pressure. The total pressure of a mixture of gases is equal to the sum of their partial pressures.

Partial pressure can be calculated by using the formula: [tex]P_{Total} =P_{N} +P_{H} +P_{H}[/tex]

Puts the value of given data in above equation.

[tex]Px_{W} =864-410-220\\\\= 234 mm Hg[/tex]

Select the part that contains the information that a plant cell uses for growth and activities.

a. golgi b. vacuole c. chromosomes d. chloroplasts

Answers

The correct answer is C. Chromosomes


Other correct options would be nucleus but since that is not an option, C would be the correct one.

Hope this helps!

The part that contains the information that a plant cell uses for growth and activities is known as Chromosome. Thus, the correct option for this question is C.

What are Chromosomes?

Chromosomes may be defined as thread-like structures that appear during cell division. These structures are present in the nucleus of the cell and are made up of DNA, RNA, histones, and some non-histone proteins.

Chromosomes were first discovered by E. Strasburger in 1875. But the term chromosome was given by Waldeyer in 1888. Ultimately, the nucleus of the cell contains all sorts of genetic information which are essential for the growth and activities of organisms.

The Nucleus contains DNA which is known as the genetic material of most organisms including plants.

Therefore, a chromosome is a part that contains the information that a plant cell uses for growth and activities. Thus, the correct option for this question is C.

These observations were made by Ernest Rutherford in his model of the atom established in 1911, when he performed his gold foil experiment and observed the scattering angle of the alpha particles which led him to conclude that the mass of the atom was concentrated at the center.

Also, that most of the alpha particles also went through the gold foil suggested that the atom was made up basically of empty space.

The empirical formula of a compound that contains only iron and oxygen and is 22.27% oxygen is FeO. The correct option is A.

What is the empirical formula?

The simplest whole number ratio of atoms in a chemical molecule is its empirical formula. The empirical formula is the chemical formula that gives the number of atoms of the chemical formula that is given in the chemical reaction.

For example, the C₆H₁₂O₆ is the formula of glucose. The simplest formula is CH₂O. This will be the simplest ratio of this compound. The first one, this C₆H₁₂O₆ is the molecular formula.

It only contains the element one quantity.  The empirical formula that contains oxygen and iron will be FeO. The empirical formulas is calculated by dividing the simplest formula.

Thus, the correct option is A) FeO.

which molecules are required for the citric acid cycle to fully oxidize the carbons donated by acetyl coa?

Answers

Explanation:

At the start of the citric acid cycle, a molecule of oxaloacetate accepts a two-carbon acetyl group from acetyl CoA to form citrate. This reaction kicks off the citric acid cycle; thus, oxaloacetate is required for the cycle to take place.

To begin the citric acid cycle, an oxaloacetate molecule accepts a two-carbon acetyl group from acetyl CoA to form citrate. Because this reaction initiates the citric acid cycle, oxaloacetate is required for the cycle to occur.

What is citric acid cycle ?

The Krebs cycle, also known as the citric acid cycle or TCA cycle, is a chain of reactions that occurs in the mitochondria and is used by almost all living cells to produce energy through aerobic respiration. It consumes oxygen and emits water and carbon dioxide as byproducts.

All aerobic organisms use a series of chemical reactions to generate energy by converting acetate derived from carbohydrates, fats, and proteins into carbon dioxide.

The citric acid cycle involves the attachment of an acetyl group from acetyl CoA to a four-carbon oxaloacetate molecule to form a six-carbon citrate molecule.

Thus, Citrate is oxidized in a series of steps, releasing two carbon dioxide molecules for each acetyl group fed into the cycle.

what type of carbohydrates provide the body with a sustained release of energy?

Answers

Answer:

Fiber-rich, complex carbs

Complex carbs with fiber take much longer to digest than simple carbs. This helps to maintain stable blood sugar levels because sugar enters the bloodstream gradually . Complex carbohydrates provide sustained energy and help you feel fuller for longer because they are digested more slowly.

Which form of carbohydrates can your body use for energy?Glucose, also known as blood sugar, is the primary energy source for your body's cells, tissues, and organs. Glucose can be used right away or stored for later use in the liver and muscles.Carbohydrates are the body's preferred fuel source because they can be quickly converted to glucose. A light carbohydrate snack right before exercise is a good idea for quick energy. Eat protein with carbs to slow the rate at which your body absorbs them for longer-lasting energy.Fat is the most concentrated source of energy in the body, providing more than twice the potential energy of carbohydrate or protein (9 calories per gram versus 4 calories each per gram).

Answer: 105 mL

Explanation:

We can use the formula M₁V₁ = M₂V₂ the total volume of water that will yield 0.800 M HCl. We can then subtract that from the initial volume to get how much water needs to be added.

Since M₁V₁ = M₂V₂    (starting mole× starting volume = end mole × end volume)

⇒  (5 mol)(20 mL) = (0.80 mol) V₂

         100 mol/mL = 0.8 mol × V₂

⇒                      V₂ = 100 mol/mL ÷ 0.8 mol

                             = 125 m

Since we began with 20.0 mL of water,

water needed to add = 125 mL - 20 mL = 105 mL
