The sun has more thermal energy than the bath tub full of hot water, because the sun has more heat than the bathe tub full of hot water.
What is thermal energy ?The energy present in a system that determines its temperature is referred to as thermal energy. Thermal energy flows as heat. Thermodynamics is a whole field of physics that studies how heat is transmitted across various systems and how work is performed in the process.
The object with the higher temperature has more thermal energy with two things have the same mass. A thermometer is used to determine temperature. Heat is the thermal energy that is transferred between things when their temperatures differ.
Undoubtedly, a colder item can possess more thermal energy than a warmer one. Here's one illustration, Thermal energy will be far more in a bathtub full of 100°F water than in a thimble full of 110°F water.
Thus, The sun has more thermal energy than the bath tub full of hot water.

Answer:
Fossils are remains or traces from ancient life's that is most likely buried in rocks anywhere in the world. Fossils are basically bones, teeth, shells, nests, leaf impressions, and footprints. That is technically explaining what our planet was like long ago. Some dinosaur fossils have been found. Paleontologists find them almost everywhere. If you don't know what Paleontologists are, they're basically people who study fossils. A lot of fossils are found in sedimentary rocks.

What is the percentage of oxygen in carbon dioxide.
A chemist reacts sodium metal (Na) and chlorine gas (Cl) to form salt according to the balanced chemical equation: Na Cl → NaCl. If the chemist has 35. 0 g Na, what mass of chlorine must he or she use to react completely with the sodium? Finally, solve (remember significant figures):.
If the chemist has 35.0 g of Na, then 26.94 grams of chlorine is required to react completely with the sodium.
How we calculate number of moles?Number of moles of any substance can be calculated as [tex]${\rm{n = }}\frac{{\rm{W}}}{{\rm{M}}}$[/tex].
Where, W = given mass
M = molar mass
Balanced equation for the formation of NaCl can be written as:
[tex]${\rm{2N}}{{\rm{a}}_{{\rm{(s)}}}}{\rm{ + C}}{{\rm{l}}_{\rm{2}}}_{{\rm{(g)}}} \to {\rm{2NaC}}{{\rm{l}}_{{\rm{(s)}}}}$[/tex]
Here the ration of Na and Cl is 2:1.
No. of moles of Na = 35/23 = 1.52 mole
If 2 moles of Na is consumed by 1 mole of Cl, then 1 mole of Na is consumed by half mole of Cl.
Mole of Cl required to consume 1 mole of Na = 1.52/2 = 0.760 mole.
Now used mass of Cl can be find out by using the formula of moles as follow:
W = 35.45 × 0.760 = 26.94 grams
Hence, 26.94 grams of Cl is required to completely react with 35.0 grams of Na.

In forest eco system the people are uncivilized and not so much educated. And in urban eco system people are intelligent as well as educated this is the main reason. In an urban ecosystem, the only non-human life that live there are the ones that are able to survive under the conditions. However, in undeveloped forest ecosystems, there’s barely any pollution. Therefore, a bigger variety of non-human life is able to live here.

How many moles of O2 are required to react with 2.4 mol of H2 ?
Please explain your answer, I’m really trying to understand the concept!!!
Answer:
1.2 moles
Explanation:
this is the balanced equation for the reaction of oxygen (O2) and hydrogen (H2), usually we don't write the 1 in front of O2
2H₂ + 10₂ → 2H₂O
the molar ratio of hydrogen to oxygen is 2 : 1
we are trying to react with 2.4 mol of H2 so the moles of O2 is half the number of moles of H2 = 2.4 ÷ 2 = 1.2 mol
another way to think of it:
2H₂ + 10₂
2 : 1
2.4 mol : x mol
to get from 2 to 2.4 multiply by 1.2, so do the same to the other side
1 × 1.2 = 1.2 mol
Given the following balanced equation:
4NH3 + 6NO --> 5N2 + 6H2O

Calculate the heat energy required to melt 4kg of ice when the specific latent heat of fusion of water is 334,000 J/kg.
1336 kJ
2336 kJ
3336 kJ
HELP ASAP
[tex]\bold{\huge{\blue{\underline{ Solution}}}}[/tex]
We have given in the question that,
4kg of ice melts at the specific latent heat of fusion of water is 334,000 J/kg .We know that,
Amount of heat required = Mass * specific heat * change in temperature
[ Specific Latent heat of fusion is the amount of heat required to change one mole of substance from solid to liquid phase without changing in temperature .]
But, For complete melting of substance without change in temperature
Amount of heat required = Mass * Specific latent heat of fusion
Subsitute the required values,
[tex]\sf{\red{ Q = MCl}}[/tex]
Where,
Q = Amount of heat required M = Mass of the substance Cl = Specific latent heatNow,
[tex]\sf{ Q = 4 × 334000}[/tex]
[tex]\sf{ Q = 1336000 J }[/tex]
[tex]\sf{ Q = 1336 KJ }[/tex]
Hence, The amount of heat required to melt 4kg ice is 1336KJ
[tex]\bold{\red{ Option\: A \:is\: correct }}[/tex]
Taking into account the definition of calorimetry and latent heat, the heat energy required to melt 4 kg of ice when the specific latent heat of fusion of water is 334,000 [tex]\frac{J}{kg}[/tex] is 1,336 kJ.
CalorimetryCalorimetry is the measurement and calculation of the amounts of heat exchanged by a body or a system.
Latent heatLatent heat is defined as the energy required by a quantity of substance to change state.
When this change consists of changing from a solid to a liquid phase, it is called heat of fusion and when the change occurs from a liquid to a gaseous state, it is called heat of vaporization.
The heat Q that is necessary to provide for a mass m of a certain substance to change phase is equal to
Q = m×L
where L is called the latent heat of the substance and depends on the type of phase change.
Heat energy required to melt iceIn this case, you know:
m= 4 kgL= specific latent heat of fusion of water= 334,000 [tex]\frac{J}{kg}[/tex]Replacing in the expression for latent heat:
Q = 4 kg× 334,000 [tex]\frac{J}{kg}[/tex]
Solving:
Q= 1,336,000 J= 1,336 kJ (being 1,000 J= 1 kJ)
Finally, the correct answer is the first option: the heat energy required to melt 4 kg of ice when the specific latent heat of fusion of water is 334,000 [tex]\frac{J}{kg}[/tex] is 1,336 kJ.
