The experiment is not found here but temperatures of soil, sand, water, and air increase by raising the supply of kinetic energy.
What is kinetic energy?Kinetic energy refers to motion (movement energy), whereas potential energy refers to stored energy, which is able to perform work.
The increase in temperature causes a rise in kinetic energy due to a higher movement of subatomic particles that form the elements above described (e.g., soil).
In conclusion, the experiment is not found here but temperatures of soil, sand, water, and air increase by raising the supply of kinetic energy.

0.39 mol Nb*92.91g Nb/1 mol Nb=36 g Nb
You start with 100mL of 14M HNO3 and 10grams of copper metal. How many moles of the nitrogen dioxide gas will be produced?
Answer:
0.316 moles are produced.
Explanation:
We state the redox reaction:
4HNO₃ + Cu → Cu(NO₃)₂ + 2NO₂ + 2H₂O
We need to determine the limting reactant:
0.1 L . 14 M = 1.4 moles
10 g . 1mol/ 63.54g =0.158 mol
Cu is the limiting reactant. Let's see
4 moles of acid need 1 mol of Cu to react
1.4 moles of acid may react to (4 . 1) / 1.4 = 0.35 moles
We do not have enough Cu.
1 mol of Cu can produce 1 mol of NO₂
Then 0.158 moles will produce, 0.316 moles. (double of moles)
If we see stoichiometry, ratio is 1:2
what is the correct answer ?
Answer:
Element with 6s subshell
Explanation:
Reactivity of an element depends on the electronic configuration and position of element in the periodic table as reactivity increases as we go down the periodic table.
This is so because number of shell increases as move down the periodic table and the last electron is further away from the nucleus.
Element with 6s subshell is the largest among 3s and 4s subshell and has more number of shells so it will react more than 3s and 4s subshell.
Hence, the correct answer is "Element with 6s subshell".

How is wind energy more environmental friendly than heat energy?
Answer:
Wind is an emissions-free source of energy
Overall, using wind to produce energy has fewer effects on the environment than many other energy sources. Wind turbines do not release emissions that can pollute the air or water (with rare exceptions), and they do not require water for cooling.

O
A. The difference in density between land and water
B. The difference in cloud cover between land and water
Ο Ο Ο
C. The difference in specific heat capacity between land and water
D. The difference in elevation between land and water
Answer:
The usual cause of sea breeze is the difference in specific heat capacity between land and water Land heats and cools more quickly than water. What is the cause of a sea breeze? The air over the land is warmed and rises, to a greater temperature than that over the sea.
Explanation:
Your answer is C ! <3
The difference in specific heat capacity between land and water is the cause of sea breeze.
What is sea breeze?land and ocean heat up at different rates, sea breezes often occur during hot, summer days. The land surface warms up more quickly than the water surface during the day. As a result, the air above land is warmer than that over water.
Just to refresh your memory, warmer air is lighter than cooler air. Warm air rises as a result. As a result, the warmer air above the ground is rising. The cooler air above the water is moving across the surface of the land to replace the rising heated air as it rises over the land.
This is the sea breeze, which is seen at the top of the next picture. The land breeze that happens is seen at the bottom of the following picture.
Therefore, The difference in specific heat capacity between land and water is the cause of sea breeze.

How is humility related to air pressure
Answer: Edmentum question:
The following graph shows the barometric pressure over the course of the day in Bellingham. What effect will this trend likely have on cloud cover and precipitation over the city?
a scatter plot showing the barometric pressure of an area, with air pressure on the y-axis and time on the x-axis
Explanation: edmentum answer:
In the graph, barometric pressure is decreasing. The drop in pressure represents a low-pressure system. This type of system will cause an increase in cloud cover and precipitation.

Explain why dissolving is classified as a physical change.
Answer:
dissolving is classified as a physical change because it can be reversed back to its original form
explanation:
Dissolving is an example of a reversible change. For example, when salt is mixed with water it disappears because it dissolves in the water to make salty water. But we can get the salt can back again by boiling off the water. That leaves the salt behind.

One use of CaCl 2 to salt roads in the winter. The equation that describes the change in freezing point of a solvent due to a solute is T f =i x K f x molality. How much would the freezing point decrease if a 3.23 molal (m) solution were achieved? (K f =1.86^ C/(mol/kg) for water and i = 3 for CaCl 2 )
Answer:
On contact with ice, calcium chloride forms brine rapidly, which lowers the freezing point of water and melts snow and ice quickly. Calcium chloride forms brine faster than other ice melters because its hygroscopic properties actually cause it to attract moisture from its surroundings

What type of weathering creates a granite Tor?
Physical or
Chemical or
Biological
Answer:
Physical
Explanation:
Physical weathering is defined as the geological process in which rocks are broken down but there is no change in their chemical composition.
Granite tor are the rock masses above the ground surface which are associated with granites
Granite Tor is an example of physical weathering as they formed by freeze–thaw weathering. Granite tor are formed when magma present in the crust cools down and form batholith. Rocks above batholith gets erodes and left the batholith to expose.
Hence, the correct answer is "Physical weathering'.
