The Thermal Energy
The thermal energy of an object is the total kinetic energy of its particles. An object's
thermal energy depends on the mass of the object, its temperature, its state of matter,
and its chemical composition. Larger objects have more thermal energy than smaller
objects of the same material and density at the same temperature. A liquid substance
has more thermal energy than the same mass of the substance in its solid form.
9. Suppose you have two identical objects made of the same mass of the same material.
If one object is 20 °C warmer than the other, which object has more thermal energy?
Thermal Energy is directly proportional to the temperature
Or
[tex]\\ \sf\longmapsto Thermal\: Energy\propto Temperature [/tex]
So if temperature increases the thermal Energy also increases.
An object which is 20°C warmer than other has more thermal energy

Would you expect the reaction of phosphoenolpyruvate to pyruvate to be a reversible reaction?
Answer:
i) In thee mitochondrion, pyruvate carboxylase converts pyruvate to oxloacetate.
ii) Malate dehydrogenase in the mitochondrion reduces oxaloacete to to malate.
iii) Malate dehydrogenase in the cytoplasm oxidizes malate to oxaloacetate.
iv) Phosphoenolpyruvate carboxykinase decarboxylates and phosphorylates oxaloacetate.forming phosphoenolpyruvate.
Explanation:
Gluconeogenesis is the synthesis of glucose from non - carbohydrate compounds. The substrates for gluconeogenesis are lactate, pyruvate, amino acids, propionate and glycerol.
Gluconeogenesis occurs only in cytosol but the precursor is produced in mitochondria. In the conversion of pyruvte to phosphoenolpyruvate occur in mitochondria and cytosol.
Step -1:
Pyruvate carboxylase is a biotin dependent enzyme located in mitochondria. It converts pyruvate to oxlaoacetate and carbondioxide in the presence of ATP.Oxlaocetate synthesized in mitochondrial matrix has to be transported to cytosol for gluconeogenesis. Oxaloacetate is impermeble, cannot be sent out of mitochondria. So it has to be converted to malate.
Step -2:
Malate dehydrogenase in mitochondria converts oxaloacetate synthesized in mitochondrial matrix to malate. And then it is transported to cytosol.
Step 3:
Malate dehydrogenase responsible for reversible reaction in cytosol converts malate to oxaloacetate.
Step -4
Phosphoenolpyruvate carboxy-kinase in cytosol converts oxaloacetate to PEP. The enzyme transfer high energy phosphate bond from GTP to oxaloacetate to from PEP and liberated carbondioxide.
Therefore, the steps of glycolysis converts phosphoenolpyruvate to pyruvate are as follows.
i) In thee mitochondrion, pyruvate carboxylase converts pyruvate to oxloacetate.
ii) Malate dehydrogenase in the mitochondrion reduces oxaloacete to to malate.
iii) Malate dehydrogenase in the cytoplasm oxidizes malate to oxaloacetate.
iv) Phosphoenolpyruvate carboxykinase decarboxylates and phosphorylates oxaloacetate.forming phosphoenolpyruvate.

Magnesium metal is reacted with hydrochloric acid to produce hydrogen gas. A sample of hydrogen gas is collected over water in a eudiometer at 28.0°C. The atmospheric pressure is 786 mmHg. Determine the pressure (in atm) of the hydrogen gas produced.
The pressure of hydrogen gas produced is 0.997 atm
Using the standard table of temperature and water vapour pressure;
At 28.0°C, the water vapour pressure = 28.3 mmHgThe pressure of hydrogen gas (H₂) collected over water is:= [tex]\mathbf{P_{moist\ gas } = 786 mmHg}[/tex]Recall that:
[tex]\mathbf{P_{moist \ gas} = P_{dry \ gas} + P_{water vapor}}[/tex]
where;
the dry gas = hydrogen gas[tex]\mathbf{ P_{dry \ gas} = P_{moist \ gas} - P_{water vapor}}[/tex]
[tex]\mathbf{ P_{dry \ gas} = (786- 28.3) mmHg}}[/tex]
[tex]\mathbf{ P_{dry \ gas} = (757.7) mmHg}}[/tex]
We know that 1 atmospheric pressure = 760 mmHg
∴
757.7 mmHg will be:
[tex]\mathbf{=\dfrac{757.7 \ mmHg \times 1 \ atm}{760 \ mmHg}}[/tex]

When 0.717 g of sodium metal is added to an excess of hydrochloric acid, 7450 J of heat are produced. What is the enthalpy of the reaction as written?
2Na(s)+2HCl(aq)⟶2NaCl(aq)+H2(g)
Answer:
The enthalpy change of the reaction is 4.78 × 10⁴ J.
Explanation:
We are given that 0.717 g of sodium metal reacts with hydrochloric acid to produce 7450 J of heat.
Converting grams of sodium to moles:
[tex]\displaystyle 0.717 \text{ g Na} \cdot \frac{1 \text{ mol Na}}{22.99 \text{ g Na}} = 0.0312 \text{ mol Na}[/tex]
And dividing the amount of heat produced by the moles of sodium reacted yields:
[tex]\displaystyle \Delta H = \frac{7450 \text{ J}}{0.312 \text{ mol Na}} = 2.39 \times 10^4 \text{ J/mol Na}[/tex]
Because the given reaction has two moles of sodium metal, we can multiply the above value by two to acquire the enthalpy change of the given reaction:
[tex]\displaystyle \Delta H = 2\text{ mol Na}\left(2.39 \times 10^4 \text{ J/mol Na}}\right) = 4.78 \times 10^4 \text{ J}[/tex]
In conclusion, the enthalpy change of the reaction is 4.78 × 10⁴ J.
How many atoms can be found in a sample of 75g of silicon
Answer:
[tex]\boxed {\boxed {\sf 1.6 \times 10^{24} \ atoms \ Si}}[/tex]
Explanation:
We are asked to find how many atoms are in a sample of 75 grams of silicon.
1. Convert Grams to MolesFirst, we must convert grams to moles using the molar mass. This is the mass of 1 mole of a substance. The molar mass is found on the Periodic Table because it is equal to the atomic mass, but the units are grams per mole instead of atomic mass units.
Look up the molar mass of silicon.
Si: 28.085 g/molWe convert using dimensional analysis, so we must set up a conversion factor.
[tex]\frac {28.085 \ g \ Si}{1 \ mol \ Si}[/tex]
We are converting 75 grams of silicon to moles, so we multiply by this value.
[tex]75 \ g \ Si*\frac {28.085 \ g \ Si}{1 \ mol \ Si}[/tex]
Flip the conversion factor so the units of grams of silicon cancel.
[tex]75 \ g \ Si*\frac {1 \ mol \ Si}{28.085 \ g \ Si}[/tex]
[tex]75 *\frac {1 \ mol \ Si}{28.085 }[/tex]
[tex]\frac {75}{28.085} \ mol \ Si[/tex]
[tex]2.670464661 \ mol \ Si[/tex]
2. Convert Moles to AtomsNext, we convert moles to atoms using Avogadro's Number, or 6.022 ×10²³. This is the number of particles (atoms, molecules, formula units, etc.) in 1 mole of a substance. In this problem, the particles are atoms of silicon.
Set up another conversion factor, this time with Avogadro's Number.
[tex]\frac {6.022 \times 10^{23} \ atoms \ Si}{1 \ mol \ Si}[/tex]
Multiply by the number of moles we found.
[tex]2.670464661 \ mol \ Si*\frac {6.022 \times 10^{23} \ atoms \ Si}{1 \ mol \ Si}[/tex]
The units of moles of silicon cancel.
[tex]2.670464661 *\frac {6.022 \times 10^{23} \ atoms \ Si}{1 }[/tex]
[tex]2.670464661 * {6.022 \times 10^{23} \ atoms \ Si}[/tex]
[tex]1.60815382 \times 10^{24} \ atoms \ Si[/tex]
The original value of grams (75) has 2 significant figures, so our answer must have the same. For the number we found, that is the tenths place. The 0 in the hundredths place tells us to leave the 6 in the tenths place.

Explanation:
How many grams of sodium chloride are dissolved in 375 ml of a 0.90% saline solution?
Answer:
337.5 g NaCl
Explanation:
.90% saline solution = 90g saline (NaCl)/100mL water (H2O)
1. Use 375 mL to find mass
375 mL × (90 g NaCl/100 mL) = 337.5 g NaCl in 375 mL .9% saline solution
The amount of sodium chloride dissolved in 375 ml of a 0.90% saline solution is 337.5 g.
What is the concentration of the solution?The concentration can be calculated when we have the molecular formula and its molecular weight. The concentration of the solution is calculated as the weight of a solute divided by the volume of the solution.
The weight/volume percentage of the solution is determined in the following way.
W/v (%) = weight of the solute/Volume of the Solution ( in mL)
Given, the concentration of the saline solution = 0.90 %
0.90 % saline solution means 90 g of NaCl is dissolved in 100 ml of water.
Given, the volume of solution = 375 ml
100 ml of saline solution containing NaCl = 90 g
Then 375 ml of saline solution containing NaCl = 90 ×375/100 = 337.5 g
Therefore, the amount of NaCl is equal to 337.5 g.

a hot air balloon has a volume of 875L. what is the original temperature of the balloon if its volume changes to 955 L when heated to 56
Answer:
using Charles law
v1/t1= v2/ t2
Explanation:
875/t1=955/56+273
t1= 329* 875/955
t1= 302.82k
The initial temperature of the hot air balloon can be calculated from Charles's law. The initial temperature of the balloon was, 51.3 °C.
What is Charles's law?According Charles's law, at constant pressure, the temperature and volume of a gas is in direct proportionality. Thus volume increases with an increase in temperature. Therefore V/T = a constant.
Let V₁ and T₁ be the initial volume and initial temperature and V₂ and T₂ be the final volume and temperature respectively. Thus we can write the relation as:
V₁ /T₁ = V₂/T₂ .
Given that the initial and final volume are 875 L and 955 L respectively. The final temperature is 56 °C. Thus the initial temperature is calculated as :
T₁ = V₁T₂/V₂
= (875 L × 56 °C )/955 L
= 51.3 °C.
Hence, the initial temperature of the hot air balloon was 51.3 °C.
