Answers

Answer 1

Answer:

5.85 g C2H6O has more carbon

Explanation:

Weight of carbon in 4.71 g of C6H12O6

[tex]4.71 * 12.01\\56.5671\\[/tex] grams

Weight of carbon in 5.85 g of C2H6O

[tex]5.85 * 12.01\\70.259\\[/tex] grams

Hence, 5.85 g C2H6O has more carbon

In order to expand agriculture and urban areas to meet increased demand for growing populations, water supplies often have to be diverted. In three to five sentences, construct a potential chain of consequences for what could happen when water is diverted from large bodies like lakes and rivers

Answers

Answer:

Decrease occur in the amount and flow of water bodies.

Explanation:

There is decrease in the amount and flow of water from water bodies such as rivers and lakes etc occur when the river is diverted from large water bodies because the water flows to the diverted sides and decrease occurs in the amount of water in the rivers and lakes. Those regions from where this river passes can also be negatively affected due to low amount of water they receives for their daily needs or for cultivation of crops so we can say that this diversion has adverse effect on other populations.

A gas occupies 12.3 L at a temperature of 40.0 K. What is the volume when the temperature is increased to 60.0 K?

Answers

Answer:

the volume is 18.45 L

Explanation:

The computation of the volume when the temperature is increased to 60.0 K is shown below:

Since the gas occupied 12.3 L at a temperature of 40.0 k

And, the volume when the new temperature is 60.0 k

So, the volume is

= 60.0 k × 12.3 L ÷ 40.0 k

= 18.45 L

hence, the volume is 18.45 L

Answers

Answer:133.4

Explanation: Explanation:

Molarity is number of moles of solute divided by number of litres of solution.

Rearrange for V to give

Number of moles of KCl is the mass divided by the molar mass of KCl which is 75.5 g/mol, so (5/75.5) = 0.0667 moles.

Now plug in the numbers:

0.0667

0.5

0.1334

litres

So you need to add 0.1334 litres of 133.4

of water.

(NB: symbol for molarity is upper case M. m is metres).

How many grams of oxygen are present in 10g of H2 SO4?

Answers

H2SO4 molecular weight is 98g/mol.

out of 98g 64g is due to oxygen

one mole of oxygen is 32g

Then 2moles of oxygen in H2SO4.

If you want to know the mass percent of a substance in a compound.

Simple formula:

Mass percent=Mass of the substance×100/Total mass of the compound

Ex:

Mass percent of oxygen in H2SO4=mass of the oxygen ×100/Total mass of the H2SO4

(i.e 16×4×100/98=65.3061%)

Here oxygen mass is multipled by 4 because there are 4 Oxygen atoms in H2SO4.

A gas made up of homonuclear diatomic molecules escapes through a pinhole 3.98 times as fast as oxygen gas. Write the Chemical formula of the gas.

Answers

Answer:

H₂

Explanation:

To solve this question we must find, as first, find the molar mass of the homonuclear diatomic gas using Graham's law. With the molar mass we can identify this gas

Graham's law:

[tex]\frac{V_a}{V_b} =\sqrt{\frac{m_B}{m_A} }[/tex]

Where V is the speed of the gases and m the molar mass of those:

As Va is 3.98 times Vb (And mB is molar mass of oxygen gas = 32g/mol)

[tex]3.98 =\sqrt{\frac{32g/mol}{m_A} }[/tex]

15.84 = 32g/mol / mA

mA = 2.02g/mol

As is a homonuclear diatomic gas, the molar mass of the atom is 1.01g/mol. Thus, the gas is:

A sample of gas is inside of a rigid container with fixed volume of 350mL. The initial pressure of the system is 366kPa, and the initial temperature is 88 degrees Celsius. How would the pressure of the system change if the temperature was increased to 110 degrees Celsius?

Answers

Answer:

457.5kPa

Explanation:

Given data

V1=V2=350mL (fixed volume )

P1=366kPa

T1= 88 degrees Celsius

P2=??

T2= 110 degrees Celsius

For the general gas equation

P1V1/T1= P2V2/T2

V1=V2

P1/T1= P2/T2

Substitute

366/88= P2/110

Cross multiply we have

P2*88=366*110

P2*88= 40260

P2= 40260/88

P2= 457.5 kPa

Hence the pressure will change to 457.5kPa

What is the purpose of a buffer?

Answers

The main purpose of a buffer solution is just to resist the change in pH so that the pH of the solution won't be much affected when we add an acid or base into it. The added acid or base is neutralized.

Answer: A buffer solution is a solution made to prevent the pH level of something from changing when you add a base or an acid to it. For example, if you put a buffer solution in a pool, and then you put chlorine in it, the chlorine's effect on the PH level will be suppressed.

9.49.8 grams of Kl is dissolved in 1.00 kg of solvent. What is the molality?

Answers

Answer:

Molality = 9.498 mol k g − 1

Explanation:

A final way to express the concentration of a solution is by its molality. The molality ( m ) of a solution is the moles of solute divided by the kilograms of solvent. A solution that contains 1.0 mol of NaCl dissolved into 1.0 kg of water is a “one-molal” solution of sodium chloride.

molality = number of moles of solute/ mass of solvent in kg

number of moles of KI = mass of KI / molar mass of KI

number of moles of KI = 9.49.8 g / 1.00 g m o l − 1

number of moles of KI = 9.498 moles

molality = 9.498 moles / 1kg

molality = 9.498 mol k g − 1
