How does temperature relate to energy?
Answer:
temperature a measurement of the average amount of energy PER UNIT OF STUFF
Heat Energy is TOTAL ENERGY IN THE STUFF
So, that's why the difference. If you have two things at the same temperature, then any one mole (which is the same as how many molecules or atoms it takes to make up the molecular weight of something in grams.. so one mole of Hydrogen weighs 1 gram, 1 mole of helium weighs 2 grams, 1 mole of Gold weight 196 grams) of the stuff will have the same amount of energy as one mole of the other stuff. If you measure by total mass though, then you realize that there are more water molecules than gold ones in the same volume of stuff, and heat is about volume and molecular density, not mass.
This is why some Stirling engine folks who have made solar plants use Helium as the working gas.. it contains a huge amount of heat for its volume (also because it is very compressible)
So.. Delta Q goes with moles, not mass.
Air is made of nitrogen, carbon dioxide, and small amounts of other gases. What is the pressure of O₂, total is 1 atm if PN₂ = 593.4 mm Hg, PCO₂ = 3.0 mm Hg, and Pothers = 7.1 mm Hg? *
0.3 atm
0.2 atm
0.4 atm
0.8 atm
Answer:
The pressure of O₂ is 0.8 atm.
Explanation:
The pressure exerted by a particular gas in a mixture is known as its partial pressure. So, Dalton's law states that the total pressure of a gas mixture is equal to the sum of the pressures that each gas would exert if it were alone:
PT = PA + PB
This relationship is due to the assumption that there are no attractive forces between the gases.
In this case:
PT=Pnitrogen + Pcarbon dioxide + Pother gases
Being:
Pnitrogen: 593.4 mmHg Pcarbon dioxide: 3 mmHgPother gases: 7.1 mmHgand replacing:
PT= 593.4 mmHg + 3 mmHg + 7.1 mmHg
you get:
PT= 603.5 mmHg
Being 760 mmHg= 1 atm, you get:
PT= 603.5 mmHg= 0.8 atm
The pressure of O₂ is 0.8 atm.

How much energy is required to raise the temperature of 74 g of water from 19 °C to 47 °C.
Answer:
The energy required is 8660.96 J.
Explanation:
Calorimetry is the measurement and calculation of the amounts of heat exchanged by a body or a system.
Sensible heat is the amount of heat that a body absorbs or releases without any changes in its physical state (phase change). This heat is given by the expression:
Q = c * m * ΔT
where Q is the heat exchanged by a body of mass m, made up of a specific heat substance c and where ΔT is the temperature variation.
In this case, you know:
C= 4.18 [tex]\frac{J}{g*C}[/tex]m= 74 gΔT= Tfinal - Tinitial= 47 C - 19 C= 28 CReplacing:
Q= 4.18 [tex]\frac{J}{g*C}[/tex] *74 g* 28 C
Solving:
Q= 8660.96 J
The energy required is 8660.96 J.

Trihydrogen monophosphide is a covalent molecule that can also act as an acid. What is the correct acid name for trihydrogen monophosphide ?
Answer:
H₃P phosphidic acid
Explanation:
The Trihydrogen monophosphide, as stated in the exercise, can act as an acid. This is pretty similar to the case of hydrogen chloride, which is a gas but it can also be an acid, in this case, chloridic acid.
In the case of trihydrogen phosphide, we can write it molecular formula which is:
H₃P
Now, this is a binary compound because its composed of only two elements, in this case, hydrogen and phosphide. To name binary acid, we need to name the non metal with the sufije idic, and then, the word acid.
Following this simple rule, the trihydrogen phosphide would be, as acid:
H₃P: phosphidic acid

Hydrogen gas reacts with chlorine gas to form hydrogen chloride as shown in the following reaction: H2 (9) + Cl2 (g) + 2HCl (9) If a 454.4 g sample of chlorine gas (MM = 71.0 g/mol) was reacted with excess hydrogen at 565 K and 2.30 atm, how many grams of hydrogen chloride gas (MM = 36.5 g/mol) are produced? g Your answer should be rounded to three significant figures. Do not include units in your answer
Answer:
467
Explanation:
ncl2 = 454.4x1/(71.0 g/mol) = 6.40 mols cl2
6.40 mols cl2 x 2molsHCL/1moleCL2 x 36.5g/1moleHCL = 467 g HCL
One mole of chlorine gas gives two moles of hydrogen chloride. Thus, 454.4 g of chlorine gas will give 467.2 g of hydrogen chloride.
What is hydrogen chloride?Hydrogen chloride is a covalent compound formed by the electron sharing of chlorine and hydrogen. It normally exists in gaseous state and can be liquified to the acidic form.
As per the balanced reaction one mole of chlorine gas gives two moles of hydrogen chloride gas. The molecular mass of chlorine gas is 71 g/mol. The molar mass of HCl is 36.5 g/mol.
Hence, 71 g of chlorine gas gives 73 g of HCl. Then, the mass of HCl produced from 454.4 g of chlorine gas is calculated as follows:
mass of HCl = (454.4 × 73) / 71
= 467.2 g.
Therefore, the mass of HCl produced from 454.4 g of chlorine gas is 467.2 g.

What should be the labels on the X-axis and Y-axis?
Answer:
The label on the X-axis is Heat Supplied or Absorbed
The label on the Y-axis is Temperature
Explanation:
The given graph is the heating curve of a substance as it is absorbs heat (increase in the x-axis) and have an increase in temperature (increase in the y-axis) between its different phases, from A to E
Therefore;
The label on the X-axis should be Heat Supplied or Absorbed
The label on the Y-axis should be Temperature
An appropriate state of phase 'A' is the solid phase of the substance where the temperature of the substance increases as heat is supplied without the substance changing into a liquid
Stage 'B' is the melting stage, when the substance transforms from solid to liquid as heat is applied, without an increase in temperature, which is seen by the horizontal line of stage 'B'
At stage 'C', the substance which is entirely liquid continues to absorb heat (moving to the right), while the temperature rises
At stage 'D', the substance in the liquid state continues to absorb heat (moving to the right), but rather than increase in its temperature, the substance transforms to the gaseous phase, which is phase 'E'
At phase 'E', the substance continue to absorb heat without changing state and therefore its temperature increases
The phases 'B', and 'D', where there is no increase in temperature as heat is added (progression to the right) are the regions where we have the latent heat of fusion and evaporation respectively.
