Answer 1
Answer:

Final answer:

The molecules AlCl3, CCl4, SCl2, and S3 have different geometries and bond angles due to the number of electron bonding pairs. As such, by increasing bond angles, the order is SCl2 < CCl4 < AlCl3 < S3.

Explanation:

The question asks us to sort the molecules AlCl3, CCl4, SCl2, and S3 by increasing bond angles about the central atom. To do this, we need to examine the geometry and the bond angles produced by the electronic arrangements of each molecule.

In AlCl3, the central atom, Al, has three bonded pairs of electrons resulting in a trigonal planar structure with bond angles of 120°. In CCl4, carbon is the central atom, and it forms four bonds with chlorine atoms, creating a tetrahedral structure. The bond angle for this molecule is approximately 109.5°. For SCl2, sulfur forms two bonds and has two lone pairs of electrons. The VSEPR model predicts a bent or V shape for the molecule, resulting in bond angles less than 109.5°. Lastly, S3 is a non-polar molecule with bond angles of 120°.

Therefore, the correct order of increasing bond angles would be SCl2 < CCl4 < AlCl3 < S3.

The diagram shows a ball resting at the top of a hill. Which statement best describes the energy in this system

Answers

Answer:

Option A is correct.

A.The potential energy in the system is greatest at X.

Explanation:

A ball resting at the top of a hill will have greatest potential energy because when an object is at rest it tend to have greatest potential energy. When It moves from position X to Y the potential energy of the ball will decrease and its kinetic energy will increase.

Answer choices are listed below.

A.The potential energy in the system is greatest at X.

B.The kinetic energy in the system is greatest at X. 
C.Total energy in the system decreases as the ball moves from X to Y.
D.Total energy in the system increases as the ball moves from X to Y.

When 8.00 × 1022 molecules of ammonia react with 7.00 × 1022 molecules of oxygen according to the chemical equation shown below, how many grams of nitrogen gas are produced?4 NH3(g) + 3 O2(g) → 2 N2(g) + 6 H2O(g)

Answers

Answer: 1.848 g

Explanation: To calculate the moles, we use the equation:

\text{Number of moles}=\frac{\text{Given molecules}}{\text {Avogadro's number}}    ....(1)

For ammonia:

Putting values in above equation, we get:

\text{Moles of ammonia}=(8.00* 10^(22))/(6.023* 10^(23))=0.132mol

\text{Moles of oxygen}=(7.00times 10^(22))/(6.023* 10^(23))=0.116mol

For the reaction:

4NH_3(g)+3O_2(g)\rightarrow 2N_2(g)+6H_2O(g)

By Stoichiometry of the reaction,

4 moles of ammonia combine with 3 moles of Oxygen

Thus 0.132 moles of ammonia will combine with=(3)/(4)* 0.132=0.009mol of oxygen

Thus ammonia is the limiting reagent as it limits the formation of product.

4 moles of ammonia produces 2 moles of nitrogen

0.132 moles of ammonia will produce=(2)/(4)* 0.132=0.066 moles of nitrogen

Molar mass of nitrogen =  28 g/mol

Amount of nitrogen produced={text {no of moles}}* {text {molar mass}}=0.066* 28=1.848g

Final answer:

In the given chemical reaction, 8.00 x 10²² molecules of ammonia would produce 37.3 grams of nitrogen gas.

Explanation:

In this chemical reaction, every 4 molecules of ammonia (NH₃) produce 2 molecules of nitrogen gas (N₂). Given you have 8.00 x 10²² molecules of ammonia, this would produce (8.00 x 10²² / 2) x 2 = 8.00 x 10²² molecules of nitrogen gas, according to the reaction stoichiometry.

One molecule of nitrogen gas (N₂) has a molar mass of 28 g/mol. To convert molecules to moles, we need Avogadro's number (6.022 x 10²³ molecules = 1 mol). So, the number of moles of nitrogen gas is (8.00 x 10²² molecules / 6.022 x 10²³ molecules/mol) = 1.33 mole.

Now, by using the molar mass of nitrogen gas, we can find the mass. So, the mass of nitrogen gas = molar mass x moles = 28 g/mol x 1.33 mol = 37.3 grams.

What would happen if you didn't have chemical energy in your body

Answers

According to law of thermodynamics, energy can neither be created nor can be destroyed. It can be converted from one from one form to another. 

Hence, the food that we eat is a source of energy. The chemical energy stored in food, is utilized for various function of body such as breathing, walking, talking, etc. Now, if you body does not have chemical energy, if will not be able to perform various task, which are essential for living. 

Due to this, absence of  chemical energy in the body, can will eventually lead to death.
If you body does not have chemical energy it will slowly shut down due to its metabolism not being able to intake more food and water. This will eventually lead to death.

Which part of the body contains enzymes that break down protein? A. Skin B. Brain C. Stomach D. Teeth

Answers

Enzymes for the breakdown of protein are present in the stomach.

What are the enzymes involved in the digestion of proteins in our body?

Pepsin

  • In the presence of an acid, the stomach secretes pepsins, which are proteolytic enzymes.
  • About 10–15% of the digestion of proteins is done by the pepsins.

Trypsin

  • It is secreted in an inactive form, trypsinogen, by the pancreas.
  • Trypsinogen is then activated in the small intestine by the enzyme enterokinase and further helps in protein digestion.

Chymotrypsin and elastase

  • These are also secreted by the pancreas.
  • Chymotrypsin and elastase are activated by trypsin.
  • Responsible for initiating the hydrolysis of protein chains into peptides.

Carboxypeptidases

  • The enzymatic action of carboxypeptidases, which are also released by the pancreas, causes the subsequent breakdown of the peptides into smaller molecules and then to individual amino acids.
