What human actions contributed to the nutrient pollution of Lake Okeechobee?
PLZ HELP MEEEEEEEEEEEEEEEE I BEG YOU
Answer:
These trends were attributed to both the increased external loads and to a reduction in the lake sediment's ability to assimilate nutrients from the water column. The main sources of external nutrient inputs are animal waste and fertilizers applied to food and forage crops.

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

What type of energy does each ball have before it falls
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.

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.

What is true about constructive interference?A.Amplitudes in the opposite direction interfere to make larger waves.B.Amplitudes in the same direction interference to larger waves.C.Amplitudes in the same direction interference to make smaller waves.
Answer:
B. Amplitudes in the same direction interference to larger waves
Explanation:
This is because constructive interference is the addition of waves to form a larger wave. In constructive interference, waves with amplitudes moving in the same direction add to form a larger wave.
1. Sequence Order the path of a sound wave
from when it is produced by a source until
it is interpreted by the brain
Answer:1. The sound waves arrive at the pinna (auricle), the only visible part of the ear.
2. Once the sound waves have passed the pinna, they move into the auditory canal (external
acoustic meatus) before hitting the tympanic membrane (eardrum).
3. Once the sound waves reach the tympanic membrane, it begins to vibrate and they enter
into the middle ear.
4. The vibrations are transmitted further into the ear via three bones (ossicles): malleus
(hammer), incus (anvil), and the stapes (stirrup). These three bones form a bridge from
the tympanic membrane to the oval window.
5. Once sound passes through the oval window, it enters into the cochlea in the inner ear.
6. Hair cells in the organ of Corti (within the cochlea) are stimulated which in turn
stimulates the cochlear branch of the vestibulocochlear nerve.
7. The cochlear nerve then transmits electrical impulses to the auditory region of the brain
in the temporal lobe.

Explanation:
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) =

How much heat must be added if 160 grams of water is heated from 24 °C to 85 °C?
(The specific heat of water is 4.184 J/g °C)
Look at picture
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)
= 40835.84J
