9. Do all enzymes function at the same pH?
Each enzyme has an optimum pH but it also has a working range of pH values at which it will still work well. This depends on the type of enzyme. The enzyme pepsin breaks down proteins in the acidic conditions of the stomach. ... Catalase has an optimum pH of 9 and a working range of between pH 7-11. Hope this was helpful

it is because far the planet is long the orbit is which make revolution longer
in the reaction :N2 + 3H2----2NH3 how many grams of H2 are needed to produce 1 mole on ammonia
The number of grams that are needed to produce 1 mole on ammonia is to be considered as the 1.52 g Hz.
Calculation of the number of grams:Here we begins the moles of ammonia for production after this it convert the number of moles of h2 for getting one mole of ammonia and then finally convert into grams
So it be like
[tex]= 1\ mol NH_3 \frac{3H_2}{2NH_3}\frac{1.01g }{1\ mol H_2}[/tex]
= 1.52 g Hz
Hence, The number of grams that are needed to produce 1 mole on ammonia is to be considered as the 1.52 g Hz.

Which layer over time due to chemical and physical weathering leads to the other layers?
Answer:
chemical weathering occurs on the surface of minerals, the water and acids that control chemical weathering require access to the surface. Physical weathering breaks the rock to provide that surface
When energy is released by the pack, what happens to the energy of the surroundings (outside the pack)?
a. The energy increases
b. The energy decreases
c. The energy stays the same
Answer:
a
Explanation:
i hope that's correct
The energy of the surroundings (outside the pack) will:
a. The energy increases, when energy is released.
Energy in the surroundings:Energy is delivered to create bonds, which is the reason the enthalpy change for it is positive to break bonds. Energy is expected to break bonds. Particles are a lot more joyful when they are "wedded" and discharge energy since it is simpler and more steady to be seeing someone.
When energy is released, the energy in the surroundings will increase.
Thus, option a is correct.

ASAP please will mark as brainlist don’t got much time
Answer:
question 4. 69.19J
question 5. 40835.84J
Explanation:
question4.
heat needed = mass × specific heat capacity × change in temperature
= 9.3× 0.240×(52-21)
=69.192J
question 5.
heat added = 160× 4.184×(85-24)

To prepare 800mL of 1M phosphate buffer of pH 7.2 (PKa=7.1), by using salt = K2HPO4 and acid = KH2PO4, the quantity of salt required is
Answer:
78.04g of 0.448 moles must be added
Explanation:
Using H-H equation we can find the pH of the buffer:
pH = pKa + log [A⁻] / [HA]
Where pH is the pH of the buffer = 7.2
pKa = 7.1
[A⁻] = [K₂HPO₄]
[HA] = [KH₂PO₄]
Replacing:
7.2 = 7.1 + log [K₂HPO₄] / [KH₂PO₄]
0.1 = log [K₂HPO₄] / [KH₂PO₄]
1.2589 = [K₂HPO₄] / [KH₂PO₄] (1)
And as the concentration of the buffer is:
1M = [K₂HPO₄] + [KH₂PO₄] (2)
Replacing (2) in (1):
1.2589 = 1M - [KH₂PO₄] / [KH₂PO₄]
1.2589 [KH₂PO₄] = 1M - [KH₂PO₄]
2.2589 [KH₂PO₄] = 1M
[KH₂PO₄] = 0.44M
And [K₂HPO₄] = 0.56M
In 800mL = 0.8L:
0.8L * (0.56mol / L) = 0.448 moles K₂HPO₄. The mass is -Molar mass K₂HPO₄: 174.2g/mol-:
0.448 moles * (174.2g / mol) =
