Answer:

Potassium is a mineral found in most of the foods we eat and is necessary in the diet because it helps with muscle movement and keeping the nervous system healthy. ... Phosphorus is also a mineral we get from eating certain foods. Phosphorus helps build strong bones and teeth.

Bromelain works by breaking the enzymes that cause browning into smaller molecules. Explain how the reaction that breaks up the

kenny6666 [7]

Bromelain separates the amino acids in the enzymes that cause browning by breaking the peptide bonds.

Explanation:

Enzymes speed up chemical reactions by lowering activation energy.

An enzyme from the stem of pineapple is called Bromelain also known as cysteine protease. It is obtained by cutting pineapple and filtering the juice of it.

Bromelain extract is a mixture of protein-digesting enzymes and several other substances in smaller quantities.

The monomers in Bromelain are numerous sub units of Sulfhydryl proteases. A free sulfyhydryl group of a cysteine amino acid side chain is required for function. By seperating proteins from amino acids the reaction that breaks up enzymes occurs.

The air pressure for a certain tire is 113 KPa. What is the pressure I’m atmosphere

Fynjy0 [20]

Answer: 1.11 atm

Explanation:

The unit of pressure include kilopascal (kPa), atmospheres (atm), mmHg etc

Now, given that:

Air pressure = 113 KPa

Convert kPa to atm

If 101.325 kPa = 1 atm

113 kPa = Z atm

To get the value of Z, cross multiply

Z atm x 101.325 kPa = 1 atm x 113 kPa

Z = ( 1 atm x 113 kPa) / 101.325 kPa

Z = 1.11 atm

Thus, the pressure is 1.11 atm

A high pressure gaseous synthesis of hydrazine (H₄N₂) is governed by the following equilibrium: <img src="https://tex.z-dn.net/?

Fynjy0 [20]

Answer:

The quantity of hydrazine formed is 3.16 mmoles

Explanation:

This is a typical equilibrium problem.

Initially we have 10 moles of ammonia, so I don't have any hydrazine or hydrogen. During the reaction, an X amount of moles of ammonia reacts to give half moles of hydrazine and hydrogen. The ratio of reagent to product is 2 to 1.

In equilibrium I will have the 10 moles of ammonia - X and X/2 moles of hydrazine and hydrogen.

2 NH₃ → H₄N₂ + H₂

Initial 10m - -

React x x/2 x/2

Eq 10-x x/2 x/2

Since the volume is 1L the concentration is molar. REMEMBER THAT IN EQUILIBRIUM WE WORK WITH MOLAR CONCENTRATIONS

The expression of Kc is [H₄N₂]. [H2] / [NH3]²

1x10⁻⁷ = [x/2] . [x/2] / (10-x)²

1x10⁻⁷ = 1/4x² / 100-20x+x²

1x10⁻⁷ (100-20x+x²) = 1/4x²

1/4x² - 1x10⁻⁵ + 2x10⁻⁶x = 0 This is a quadratic equation

1/4 = a ; 2x10⁻⁶ = b ; -1x10⁻⁵ = c

(-b +- √(b²-4ac))/2a

x1 = 6.32x10⁻³

x2 = -6.32x10⁻³

Concentrations can not be negative, so we take x1

[H₄N₂] = x/2

[H₄N₂] = 6.32x10⁻³/2 = 3.16x10⁻³ moles

1mmol = 1000 moles

3.16x10⁻³ moles . 1000 = 3.16 mmoles
