Answer:

Glands in your stomach lining make stomach acid and enzymes that break down food. Muscles of your stomach mix the food with these digestive juices. Your pancreas makes a digestive juice that has enzymes that break down carbohydrates, fats, and proteins, along with your liver that makes a digestive juice called bile, which helps digest fats and some vitamins. The pancreas delivers the digestive juice to the small intestine through small tubes called ducts. Bacteria in your small intestine make some of the enzymes you need to digest carbohydrates. It also absorbs water with other nutrients. Bacteria in your large intestine help break down remaining nutrients and make vitamin K NIH external link. Waste products of digestion, including parts of food that are still too large, become stool.

Some extra info, but the main ones are there for you :)

Explanation:

Mouth. The digestive process starts in your mouth when you chew. Your salivary glands make saliva, a digestive juice, which moistens food so it moves more easily through your esophagus into your stomach. Saliva also has an enzyme that begins to break down starches in your food.

Esophagus. After you swallow, peristalsis pushes the food down your esophagus into your stomach.

Stomach. Glands in your stomach lining make stomach acid and enzymes that break down food. Muscles of your stomach mix the food with these digestive juices.  

Pancreas. Your pancreas makes a digestive juice that has enzymes that break down carbohydrates, fats, and proteins. The pancreas delivers the digestive juice to the small intestine through small tubes called ducts.

Liver. Your liver makes a digestive juice called bile that helps digest fats and some vitamins. Bile ducts carry bile from your liver to your gallbladder for storage, or to the small intestine for use.

Gallbladder. Your gallbladder stores bile between meals. When you eat, your gallbladder squeezes bile through the bile ducts into your small intestine.

Small intestine. Your small intestine makes digestive juice, which mixes with bile and pancreatic juice to complete the breakdown of proteins, carbohydrates, and fats. Bacteria in your small intestine make some of the enzymes you need to digest carbohydrates. Your small intestine moves water from your bloodstream into your GI tract to help break down food. Your small intestine also absorbs water with other nutrients.

Large intestine. In your large intestine, more water moves from your GI tract into your bloodstream. Bacteria in your large intestine help break down remaining nutrients and make vitamin K NIH external link. Waste products of digestion, including parts of food that are still too large, become stool.

Explanation:

I did this alderman

Answer:

The length of the bond is determined by the number of bonded electrons (the bond order). The higher the bond order, the stronger the pull between the two atoms and the shorter the bond length. Generally, the length of the bond between two atoms is approximately the sum of the covalent radii of the two atoms.

Answer:

The compound with the correct formula is;

A. MNO₃

Explanation:

The number of oxidation states in the metal, M = One oxidation state

The formula of the compound formed by the metal, M = MHCO₃

We note that the ion HCO₃⁻, known as hydrogen carbonate has an oxidation number of -1

Similarly nitrate, NO₃⁻ has an oxidation number of -1, therefore, the metal M can form similar compound formed with HCO₃⁻ with nitrate, and we have;

The possible compounds formed by the metal 'M' includes MHCO₃ and MNO₃.

Answer:

You can make 149.1g of KCl

Explanation:

1 mole of potassium chloride, KCl, contains 1 mole of potassium, K. That means, with 2.000 moles of K we can make 2.000 moles of KCl. To solve this question we must convert these moles of KCl to mass in grams using its molar mass (Molar mass KCl = 74.5513g/mol):

Mass KCl:

2.000 moles KCl * (74.5513g / mol) =

Answer:

3.36 dm³

Explanation:

STP: Means Standard temperature and pressure.

According to Avogadro's Law, it states that the molar volume of every gas is the volume occupied by one mole of that gas at stp and is equal to 22.4 dm³

From the question,

1 mole of Nitrogen gas (N₂)  occupies a volume of 22.4 dm³

But,

1 mole of nitrogen gas has a mass of 28 g

Therefore,

28 g of nitrogen gas occupies a volume of 22.4 dm³,

Then,

4.2 g will occupy a volume of X dm³

X = (22.4×4.2)/28

X = 3.36 dm³

Answer:

7.97 moles

Explanation:

The number of moles (n) of iron (Fe) in this question can be calculated by dividing its number of atoms by Avogadro's number (6.02 × 10²³ atoms).

That is;

n = number of molecule ÷ Avogadro's number

According to this question, the number of atoms of Fe is given as 4.8 x 10²⁴ atoms.

Hence,

n = 4.8 x 10²⁴ ÷ 6.02 × 10²³

n = 4.8/6.02 × 10^(24-23)

n = 0.797 × 10¹

n = 7.97 moles

Explanation:

Answer:

Part A

pH ≈ 2.273

Part B

ΔpH ≈ -4.726

Part C

pH ≈ 1.973

Part D

ΔpH ≈ -0.301

Explanation:

Part A

The pH of a solution is given by the negative concentration of hydrogen ions in the solution

2.0 mL = 0.002 L

The number of moles of HCl in 2.0 mL of 4.0 M HCl is given as follows;

1 Liter of 4.0 M HCl contains 4.0 moles of HCl

2.0 mL = 0.002 L 4.0 M HCl contains 0.002 L/(1 L) × 4.0 M = 0.008 moles of HCl

The concentration of 0.008 moles in 1.50 L is given as follows;

Concentration = The number of moles/(The volume in liters)

∴ The concentration of 0.008 moles in 1.50 L, C = 0.008 moles/(1.5 L + 0.002 L)

∴ The concentration of 0.008 moles in 1.50 L, C ≈ 0.00533 moles/liter = 0.00533 M HCl

Given that HCl is a strong acid, we have that HCl dissociates completely to give equal number of H⁺ and Cl⁻ ions;

The number of moles of [H⁺] in the solution = 0.00533 moles

The pH of the solution = -log[H⁺]

∴ pH = -log[5.33 × 10⁻³] ≈ 2.273

The pH of the 1.5 L of pure water will be approximately 2.273

Part B

The pH of the pure water has changed from neutral (pH = 7) tp pH = 2.273

The change in pH is ΔpH = 2.274 - 7 = -4.726

ΔpH ≈ -4.726

Part C

When 2.0 mL of the 4.0 M HCl is added, the solution above, we have;

C = (0.008 + 0.008)/(1.5 + 0.002 + 0.002) ≈ 1.06383 × 10⁻²

The concentration of the solution becomes, C ≈ 1.06383 × 10⁻² mole/liter

The pH becomes, pH = -log(1.06383 × 10⁻²) ≈ 1.973

Part D

The amount by which the pH has changed, ΔpH ≈ 1.973 - 2.274 = -0.301.

Answer:

10.1 M

Explanation:

Applying,

pH = -log(H⁺).................... Equation 1

But,

[H⁺][OH⁻] = 1×10⁻¹⁴................ Equation 2

Where [H⁺] = Hydrogen ion concentration, [OH⁻] = Hydroxyl ion concentration.

From the question,

Given: [OH⁻] = 1.25×10⁻⁴ M

Substitute into equation 2

[H⁺][1.25×10⁻⁴] = 1×10⁻¹⁴

[H⁺] = 1×10⁻¹⁴/1.25×10⁻⁴

[H⁺] = 0.8×10⁻¹⁰ M

[H⁺] = 8×10⁻¹¹ M

Also, Substitute the value of [H⁺] into equation 1

pH = -log[8×10⁻¹¹]

pH = 10.1 M

You can use a very simple formula for first order decay...

Fraction Remaining (FR) = 0.5n where n is the number of half lives that have elapsed.

In the current problem we want to find the FR, and we know n = 2 half lives elapsed (60 yr/30yr = 2)

FR = 0.52 = 0.25

Since we started with 5.0 g, and we have 0.25 (1/4) left, that would be 5.0 g x 0.25 = 1.25 g

Answer:

C. They are basic

Answer:

A

Explanation:

A catalyst speeds up a reaction by lowering the required activation energy, so it's not B. Like previously stated, the catalyst lowers the activation energy required, so it's not C either. This leaves us with A. Just to double check, does a catalyst speeds up a reaction? Yes! So like it says in A, a catalyst causes the equilibrium to be reached faster. Have a nice day! :)

Catalysts speed up a chemical reaction by causing equilibrium to reach quickly while maintaining the equilibrium's position. Thus, option A is true.

A catalyst increases the reaction rate by decreasing the activation energy of the reaction. As the minimum energy required by the reactants for the reaction is decreased the rate of the formation of products increases.

During the reaction, the catalyst remains unchanged and does not undergo any chemical change. It can increase the reaction rate of both irreversible and reversible reactions.

In an equilibrium reaction, the catalyst can increase the rate of both forward and reverse reaction by reaching the reaction equilibrium at a faster rate and can move the reaction toward the products as well as a reactant.

Therefore, the catalyst causes equilibrium to be reached faster.
