what are the characteristics of temperature
A Temperature is a unit used to represent hotness or coolness on any of a number of scales, including Fahrenheit and Celsius. The direction that heat energy will spontaneously flow depends on temperature. It measures the average kinetic energy of the substances also.
The average kinetic energy of the particles in an object is measured by its temperature. The velocity of these particles likewise increases as the temperature rises. A thermometer or a calorimeter is used to determine the temperature.
Our weather is made up of several various elements, including temperature, cloudiness, wind speed, and the quantity and type of moisture in the air.
Thus temperature determines the weather and kinetic energy.

A dry cleaning solvent (molar mass = 146.99 g/mol) is a compound containing C, H & Cl is suspected to be a cancer causing agent. When a 0.250g sample was studied by combustion analysis, it was found that 0.451g of CO2 and 0.0617g of H2O were produced. From this data determine the empirical and molecular formula of the dry cleaning agent.
Answer:
Okay so set up an equation for what's happening
_C + _H + _Cl + O2 --> _CO2 + _H2O
0.451g of CO2. Convert to moles by using the molar mass of CO2 which is 44 g/mol. Now look at the ratio between Carbon and Oxygen in CO2. It's 1C:2O You just want to find C.. so do the number of moles CO2 and multiply it by 1 since the ratio says 1 carbon atom. Now you have moles of carbon. Put this number aside for later.
Do the same thing with H2O. Convert to moles by using the molar mass of H2O which is 18 g/mol. Now look at the ratio between Hydrogen and Oxygen. It's 2H:1O You just want H.. so do the number of moles of H2O and multiply it by 2 since there's 2 hydrogen atoms. Now you have the moles of hydrogen & put this number aside for later

What is the sequence of coefficients that will balance the following decomposition reaction of dihydrogen monosulfide? H₂S ----> H₂ + S₈
8 S
In this case you must start balancing the sulfur to have 8 on each side of the reaction. So:
Answer:
Explanation:
The law of conservation of matter states that since no atom can be created or destroyed in a chemical reaction, the number of atoms that are present in the reagents has to be equal to the number of atoms present in the products.
Then, you must balance the chemical equation. For that, you must first look at the subscripts next to each atom to find the number of atoms in the equation. If the same atom appears in more than one molecule, you must add its amounts.
The coefficients located in front of each molecule indicate the amount of each molecule for the reaction. This coefficient can be modified to balance the equation, just as you should never alter the subscripts.
By multiplying the coefficient mentioned by the subscript, you get the amount of each element present in the reaction.
Then, taking into account all of the above, you can determine the amount of elements on each side of the equation:
Left side: 2 H and 1 S
Right side: 2 H and 8 S
In this case you must start balancing the sulfur to have 8 on each side of the reaction. So:
8 H₂S → H₂ + S₈
Now the amount of elements on each side of the equation:
Left side: 16 H and 8
Right side: 2 H and 8 S
Now you need to start balancing the hydrogen to get the same amount from each side of the reaction. So:
8 H₂S → 8 H₂ + S₈
Now the amount of elements on each side of the equation:
Left side: 16 H and 8
Right side: 16 H and 8 S
The balanced reaction is:
8 H₂S → 8 H₂ + S₈

Why is it that the decomposition of nitroglycerin can result in so
much more volume than the decomposition of sodium azide?
Answer:
with the molecular formula C3H5(ONO2)3, has a high nitrogen content (18.5 percent) and contains sufficient oxygen atoms to oxidize the carbon and hydrogen atoms while nitrogen is being liberated, so that it is one of the most powerful explosives known.
Explanation:
NTG reduces preload via venous dilation, and achieves modest afterload reduction via arterial dilation. These effects result in decreased myocardial oxygen demand. In addition, NTG induces coronary vasodilation, thereby increasing oxygen delivery.
The decomposition of nitroglycerin can result in so much more volume than the decomposition of sodium azide nitroglycerin contains a lot of nitrogen (18.5%) and has enough oxygen atoms.
What is volume?A measurement of three-dimensional space is volume. It is frequently expressed quantitatively using SI-derived units, like the cubic metre or litre, or different imperial or US-standard units, including the gallon, quart and cubic inch. Volume and length (cubed) have a symbiotic relationship.
The total volume much a container is usually thought of as its capacity, not as the amount of space it takes up. In other words, the volume is the quantity of fluid (liquid or gas) that the container may hold. The decomposition of nitroglycerin can result in so much more volume than the decomposition of sodium azide nitroglycerin contains a lot of nitrogen (18.5%) and has enough oxygen atoms for the nitrogen to be liberated while also oxidising the hydrogen and carbon atoms.
Therefore, the decomposition of nitroglycerin can result in so much more volume than the decomposition of sodium azide nitroglycerin contains a lot of nitrogen (18.5%) and has enough oxygen atoms.

_N2 + _H2 = _NH3
Will there be any leftover reactants left?
(Kinda urgent)
Answer:
This reaction is the synthesis of Ammonia using Nitrogen and Hydrogen gas.
N+H→NH3
We must remember that Nitrogen and Hydrogen are both diatomic molecules in their standard gas form. This adjusts the equation to
N2+H2→NH3
Now we need to adjust coefficients in order to balance the atoms on each side of the equation. Currently, we have 2 atoms of nitrogen and 2 atoms of hydrogen on the reactant side and 1 atom of nitrogen and 3 atoms of hydrogen on the product side.
We can balance the hydrogens by placing a coefficient of 2 in front of ammonia and a coefficient of 3 in front of the hydrogen.
N2+3H2→2NH3
This gives us 6 hydrogen on each side and coincidentally the nitrogens now equal 2 on each side.
Explanation:
I hope this was helpful.
SMARTERTEACHER
Answer:
Balance the equation N2 + H2 ⇒ NH3
Balancing chemical equations is usually easier than it looks
There are 2 Nitrogens and 2 Hydrogens on the left side
There are 1 Nitrogen and 3 Hydrogens on the right side
Hydrogen seems to be the more complicated term so we should start with that
_N2 + _H2 ⇒ _NH3
With 2 H on one side and 3 on the other, our common multiple is 6
To balance the H we need to multiply H2 by 3 and NH3 by 2
_N2 + 3H2 ⇒ 2NH3
Now that we have H balanced, we need to look at N
There are 2 Nitrogens on both sides of the equation, so in this case, it is done

What word is the biotic factor in this sentence:
Fish breath oxygen that is dissolved in water.
Answer: Fish
Explanation:
Biotic factor is one of the component of the ecosystem. It is the living component of the ecosystem. It is affected or influenced by the non-living or abiotic components of the ecosystem like water, air, sunlight, and others. Fish is an example of biotic factor which is dependent on abiotic component that is oxygen which is the chief gas required for the breathing. The oxygen is one of the components of the water. So, the oxygen is dissolved in water and the fish acquire the oxygen through water only.

Determine the mass, in grams, for 1.20e24 molecules of H₂
Answer:
3.98g
Explanation:
Given parameters:
Number of molecules = 1.2 x 10²⁴ molecules
Unknown:
Mass of H₂ = ?
Solution:
To find the mass of this molecule, we use the expression below:
Mass = number of moles x molar mass
Molar mass of H₂ = 2(1) = 2g/mol
6.02 x 10²³ molecules are contained in 1 mole of a substance
So; 1.2 x 10²⁴ molecules will have [tex]\frac{1.2 x 10^{24} }{6.02 x 10^{23} }[/tex] = 1.99 moles of H₂
Mass of H₂ = 1.99 x 2 = 3.98g
The original phase and final phase of a substance are shown. Phase Transition Original Phase Final Phase Solid Liquid What most likely happened during the phase transition?
Answer:
The question appears to speak to the process between Liquid and Solid phases of a substance and seeks to resolve what happened in between.
The short answer is that the solid melted.
Explanation:
Melting is the process of a solid becoming fluid. When the reverse happens, (that is a liquid being solid), is called solidification. There is a temperature at which substances take their liquid form. That temperature is called the melting point. The melting point of ice (that is the temperature at which it starts to turn back to water) for instance is 32 °F.
According to the mechanics of melting, the internal energy of the solid increases, because of exposure to heat and or pressure usually through the application of heat or pressure, which increases the substance's temperature to the melting point.
