Benzene, C6H6, reacts with oxygen, O2, to form CO2 and H2O. How much O2 is required for the complete combustion of 1.0 mol C6H6?

After four hours of cooling, the soup reached a temperature of 140 F (or) 42 C.

Explanation:

A food worker allowed a cup of soup to cool for two hours,

step 1: The temperature attained in two hours is 70 F (or) 21 C

step 2: Consequently, in four hours, this doubles the value

Therefore, the temperature after four hours is 2(70)= 140 F (or) 2(21)= 42 C

Response:

1.98 M

Clarification:

Provided data

• Starting volume (V₁): 93.2 mL

• Starting concentration (C₁): 2.03 M

• Water volume added: 3.92 L

Step 1: Convert V₁ to liters

Using the relationship 1 L = 1000 mL.

Step 2: Calculate the final volume (V₂)

The final volume is the total of the initial volume and the added water volume.

Step 3: Calculate the final concentration (C₂)

Utilizing the dilution rule.

Response:

4

Reasoning:

Answer:

The answer is 930 grams of platelets.

Explanation:

The amount of blood given is 1.89 pints. To convert this to gallons:

= 1.89/8 = 0.236 gallons

Since 1 gallon is equal to 3.785 liters,

0.236 gallons equals = 0.236 * 3.785 L = 0.89 L

Given that 1 liter of blood contains 1.04 kilograms of platelets, thus, 0.89 L of blood will have = 1.04 * 0.89 = 0.93 kg of platelets.

As 1 kg equals 1000 grams, the amount of platelets in grams translates to:

= 1000 * 0.93 = 930 grams of platelets.

Answer:

The flask yielding the greatest amount of product is the second flask.

The water molecules produced are

Explanation:

From the prompt we learn that

The chemical reaction is

2CH3OH(l) + 3O2(g)⟶4H2O(g)+2CO2(g)

The first flask contains 3 molecules of C H 3 O H and 3 molecules of O 2

The second flask has 1 molecule of C H 3 O H and 6 molecules of O 2.

The third flask consists of 4 molecules of C H 3 O H and 2 molecules of O 2.

Analyzing the three flasks, it's evident that the flask producing the most considerable total product is the second one.

According to the balanced equation, 2 moles of C H 3 O H react with 3 moles of oxygen, making O 2 the limiting reagent.

Generally, one mole of any substance is of that substance.

Here, represents Avogadro's number valued at .

As seen in the balanced equation, 3 moles of O 2 (3 * molecules of O 2) yield 4 moles of H2O (4 *

Thus, 6 molecules of O 2 would generate X molecules of H 2 O.

So

=>
