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.

Which of the following is the smaller atom: magnesium or chlorine?
Answer:
Chlorine atoms are smaller
Explanation:
Magnesium have more electrons than chlorine.
Answer: Chlorine
Explanation: Since chlorine's 17 protons are greater than magnesium's 12 protons, chlorine will have a greater effective nuclear charge to draw chlorine's valence electrons closer to the nucleus and, thus, chlorine is expected to have the smaller atomic radius, while magnesium with the lower effective nuclear charge is expected to have the larger atomic radius.
What the difference between the tundra and the coniferous forest
Answer:
Differences in Plant Life
The taiga has a thick forest of conifers such as pine and spruce, while in the tundra trees are absent completely. This is due in part to the lack of water available in the tundra, but also is a result of permafrost.

Explanation:
Solid iron pellets are heated, melted and drawn into wires. This is an example of a chemical reaction
True
False
Answer:
false
Explanation:
It is a physical reaction because it is being heated.
Answer:
False
Explanation:
Just because the iron was melted into wires does not mean that it isn't iron. It is still iron just in a different form.
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.

___________________is the rate that an object moves in a certain direction. Question 3 options:
Speed
Displacement
Direction
Velocity
Answer: Velocity
Explanation:
i just took the quiz for k12
Velocity is the rate at that an object moves in a certain direction. The correct option is d.
What is velocity?The directional speed of an item in motion, as measured by a specific unit of time and observed from a certain point of reference, is what is referred to as velocity. A vector is a velocity. It comprises both magnitude and direction.
The size of velocity is speed. In still air, a particle gravitationally settles and quickly reaches its terminal velocity. The term "settling velocity" refers to a particle's final speed in a still fluid (also known as the "sedimentation velocity").
The particle settling velocity in the foreshore region plays a significant role in understanding fluctuations in the hydraulic regime and interactions between sediment and fluid in the surf zone.
Therefore, the correct option is d, Velocity.

Explanation:
[tex]602 \div 100 \times 1023[/tex]A cold can of soda is taken out of the refrigerator. It slowly warms up until it is at room temperature. Once the soda has warms up, it has more thermal energy than it had in the refrigerator. Where did this additional thermal energy come from?
Answer:
See explanation
Explanation:
We know that the thermal energy of a substance largely depends on the temperature of the body. This implies that the hotter a substance is, the greater its thermal energy and vice versa.
When you bring a cold can of soda out of the refrigerator, the molecules of air at room temperature gradually loose energy to the can and condense around it. This transfers thermal energy from the air particles to the molecules in the cold can of soda and the soda warms up pretty soon!
how many molecules of water are produced when 3.14 grams of ammonium nitrate are decomposed
Answer:
See the last entry
Explanation:
Remark
Ammonium Nitrate decomposes as follows.
NH4NO3 → N2O + 2H2O
If this does not agree with the reaction you have, let me know.
Step One
Find the molecular Mass of Ammonium Nitrate.
N = 1 * 14 = 14
H = 1 * 3 = 3
N = 1 * 14 14
O3 = 3*16 = 48
Molar Mass =69
Note: the masses used are approximate. Every periodic table is different. When you answer this question use the masses on your periodic table. My numbers are just guides.
Step Two
Find the number of mols in Ammonium Nitrate.
Formula
mols = given mass / molar mass
Givens
given mass = 3.14
Molar Mass = 69
mols = 3.14 / 69
mols = 0.0455
Step 3
moles of water.
1 mol of Ammonium Nitrate = 2 mols of water
0.0455 mols of Ammonium Nitrate = x mols of water
x = 2* 0.0455 mols of water.
x = 0.091 mols of water
Step 4
Find the molecules of water.
1 mol of water = 6.02*10^23 molecules of water
0.091 mol water= x
x = 0.091 * 6.02*10^23
x = 5.48 * 10^23
