The solution has a concentration 20 mgr in each mL of the final solution.

To solve this problem, we need to know about concentration. The concentration formula can be defined as how much the mass per unit volume is. It can be written as

M = m/V

where M is concentration, m is mass of solute, V is the total volume of solution.

From the text we know that :

m = 10g

vsolvent = 45mL

vsolute = 5 mL

find the total volume (V)

V = vsolvent + vsolute

V = 45 + 5

V = 50mL

Then, find the concentration

M = m/V

M = 10gr / 50 mL

M = 1000 mgr / 50mL

M = 20 mgr / mL

Hence, the solution has a concentration 20 mgr in each mL of the final solution.

Identify the number of moles in 369 grams of calcium hydroxide. Use the periodic table and the polyatomic ion resource.
topjm [15]

Answer : The number of moles in 369 grams of calcium hydroxide is, 4.98 moles

Explanation : Given,

Mass of calcium hydroxide = 369 g

Molar mass of calcium hydroxide = 74.093 g/mole

Formula used :

\text{Moles of calcium hydroxide}=\frac{\text{Mass of calcium hydroxide}}{\text{Molar mass of calcium hydroxide}}

Now put all the given values in this formula, we get the moles of calcium hydroxide.

\text{Moles of calcium hydroxide}=\frac{369g}{74.093g/mole}=4.98mole

Therefore, the number of moles in 369 grams of calcium hydroxide is, 4.98 moles

In the citric acid cycle (also known as the Krebs cycle), acetyl CoA is completely oxidized. From the following compounds involv
REY [17]

Answer:

We place ( O₂, CO₂, coenzyme A and acetyl CoA) into bin [not input or output];

We place (ADP, NAD⁺, Glucose) into [ Net Input] bin.;

And (ATP, NADH and Pyruvate) intothe [Net Output] bin.

Explanation:

Citric Acid Cycle is also known as Tricarboxylic Acid Cycle, Krebs Cycle and Szent-Györgyi-Krebs cycle.

It is a series of enzyme-catalyzed chemical reactions, which of central importance in all living cells that use oxygen as part of cellular respiration.

Here are few things to know about the CAC:

• The Krebs cycle uses the products of Glycolysis to produce 2 ATP molecules for each molecule of Glucose.

• Oxygen is required.

• The Krebs Cycle occurs in cellular power plant — Mitochondria of the cell.

• Each glucose molecule nets 2 pyruvic acids. The Krebs Cycle breaksdown 1 pyruvic acid one at å time.

• CAC begins and ends with Oxaloacetic Acid - a 4 carbon molecule.

• It is an 8 step cycle that begins when the Acetyl CoA that is a product of Glycolysis is 'picked up' by Oxalacetic Acid.

• Lipids, Proteins and Carbohydrates can all be metabolized in the Krebs Cycle.

• The NADH and FADH2 that are high energy co- enzymes (helper molecules) are by-products of the Krebs cycle and continue on to fuel the Electron Transport Chain.

The clues above helps us to know where to drag the compounds into;

We place these into bin of [Net Input]: ADP, NAD⁺, Glucose

We place these into the bin of [Net Output]: ATP, NADH and Pyruvate,

We place the following into [not input or output] bin: O₂, CO₂, coenzyme A and acetyl CoA
