Time is the ongoing progression of existence and things that happen in what seems to be an irrevocable order from the past, present, and forward into the future. It is a quantity that is a part of several measurements that are used to compare the length of events or the gaps between them.

To compare how long they last, to order events, and to measure how quickly things change in the real world or in our conscious experience. Along with the three spatial dimensions, time is frequently referred to as an a fourth dimension. A body was discovered in the woods. The man has been missing for two days.

The pH of the buffer prepared by adding 275 mL of .676M of HCl to 500 mL of .525M sodium acetate is 6.45.

The pH of a buffer solution can be calculated by initially calculating the millimoles of both the conjugate base and acid.

From, Henderson Hasselbalch equation,

pH = pKa + log conjugate base/acid

pka of HCl = -6.3

-6.3 + log 262.5/185.9

6.3 + 0.15

pH = 6.45

Therefore, the pH of the buffer prepared by adding 275 mL of .676M of HCl to 500 mL of .525M sodium acetate is 6.45.

The molarity of a solution that contains 35.00 g of CuSO4 dissolved in 250.0 mL of water is 0.88M.

The molarity of a solution can be calculated using the following formula:

Molarity = no of moles/volume

According to this question, a solution consists of 35.00 g of CuSO4 dissolved in 250.0 mL of water.

no.of moles of CuSO4 = 35g ÷ 159.6g/mol

no. of moles of CuSO4 = 0.22 moles

Therefore; molarity of CuSO4 solution is calculated as follows:

M = 0.22 ÷ 0.25

M = 0.88M

Therefore, the molarity of a solution that contains 35.00 g of CuSO4 dissolved in 250.0 mL of water is 0.88M.

Answer:

About 7.9 L.

Explanation:

We can utilize the ideal gas law. Recall that:

[tex]\displaystyle PV = nRT[/tex]

Because the amount of carbon dioxide does not change, we can rearrange to formula to:
[tex]\displaystyle \frac{PV}{T}= nR[/tex]

Because the right-hand side stays constant, we have that:
[tex]\displaystyle \frac{P_1V_1}{T_1} = \frac{P_2V_2}{T_2} = nR[/tex]

Hence substitute initial values and known final values:
[tex]\displaystyle \begin{aligned} \frac{(793\text{ mm Hg})(4.65 \text{ L})}{(22 \text{ $^\circ$C})} & = \frac{(743 \text{ mm Hg})V_2}{(35\text{ $^\circ$C})} \\ \\ V_2 & = 7.9\text{ L}\end{aligned}[/tex]

Therefore, the final volume is about 7.9 L.

Fission is when the parent atom splits into two daughter products. Whereas atom with a mass number is lower by 4 and an atomic number is lower by 2.

Fission outcomes emit beta radiation, while actinides mainly emit alpha radiation. Many of each also radiate gamma radiation.

The beta decays form an isobaric, fission-product decay chain for each mass number.

Thus, Fission is when the parent atom splits into two daughter products.

Explanation:

the molar mass of sulfur trioxide is about 80.06, so 80.06 grams per mol, 0.96*80.06=76.86g

Answer: 0.109 mol

Explanation:

Balanced chemical equation:

3 Na(s) + AlCl3(aq) --> 3 NaCl(aq) + Al(s)

3 moles of sodium metal react with 1 mole of aluminum chloride to produce 3 moles of aluminum chloride and 1 mole of solid aluminum

Molar mass of Na = 22.99 g/mol

Mass(Na) = 7.5 g

Find number of moles of Na:

n = mass of Na/molar mass of Na

=(7.5 g)/(22.99 g/mol)

= 0.3262 mol

Molar mass of AlCl3,

MM = 1*MM(Al) + 3*MM(Cl)

= 1*26.98 + 3*35.45

= 133.33 g/mol

Mass(AlCl3) = 20.0 g

Find number of moles of AlCl3,

n = mass of AlCl3/molar mass of AlCl3

=(20 g)/(1.333*10^2 g/mol)

= 0.15 mol

Balanced chemical equation is:

3 Na + AlCl3 ---> Al + 3 NaCl

3 mol of Na reacts with 1 mol of AlCl3

for 0.3262 mol of Na, 0.1087 mol of AlCl3 is required

But we have 0.15 mol of AlCl3

So, Na is the limiting reagent and we will use it in our further calculations.

According to balanced equation:

mol of Al formed = (1/3) * moles of Na

= (1/3)*0.3262

= 0.1087 mol

Answer: 0.109 mol of aluminum will precipitate out as a result of the reaction

The amount of heat absorbed in kilojoules when 3.5 moles of water react is 1635.08 KJ

6CO₂ + 6H₂O → C₆H₁₂O₆ + 6O₂  ΔH = 2803 KJ

From the balanced equation for above,

6 moles of water reacted to absorb 2803 KJ of heat

From the balanced equation for above,

6 moles of water reacted to absorb 2803 KJ of heat

Therefore,

3.5 moles of water will react to absorb = (3.5 × 2803) / 6 = 1635.08 KJ of heat

Thus, 1635.08 KJ of heat were absorbed by the reaction.
