Answer:

5.7 M

Explanation:

You have .390 L of 4.6 M HCl.

.390 L * 4.6 mol/L = 1.794 mol HCl

.390-.074=.316 L solvent remaining

1.794 mol/.316 L=5.7 M HCl

Answer:

B. 225 W

Explanation:

Power is the measure of the amount of work done in a certain time frame. It can be found using the following formula.

p=w/t

where w is the amount of work done in joules and t is the amount of time in seconds.

We know that 900 joules of work was done in 4 seconds.

w=900 J

t= 4 s

Substitute these values into the formula.

p=900 J/ 4 s

Divide 900 by 4

900/4=225

p= 225 J/s

1 Joules of work per second (J/s) is equal to 1 Watt (W). Therefore, we can substitute Watts for Joules per second.

p= 225 Watts

The power is 225 Watts, and the correct answer is B.

Answer:

The energy absorbed in the first move is greater than the energy released in the second move.

Explanation:

The greater the level number the greater the energy.

A movement up a level requires energy so energy id absorbed.

Dropping down a level releases energy.

Answer:

Individual grain of rice will sink.

Explanation:

Given:

Rice bulk density = 0.9 g/ml,

Individual grain of rice density = 1.1 g/ml

Water density = 1.0 g/ml

Find:

What happens with a cup of rice when poured into water =?

Explanation:

Each piece of grains of rice will sink into the water because individual grains of rice has a higher density than water.

Answer:

1.66 * 10^-18 mol of Argon

Explanation:

Avogadro says 1 mol of anything has 6.022* 10^23 atoms/particles. Thus using this principle, 1 million argon atoms will have

[tex]1,000,000 atoms Argon * \frac{1mol Argon}{6.022*10^{23} atoms }[/tex]

[tex]1.66*10^{-18} mol \\\\ of Argon[/tex]

One million argon atoms is equivalent to 1.7 × 10⁻¹⁸ moles of argon atoms.

To convert one million (10⁶) argon atoms to moles of argon atoms, we will use Avogadro's number: there are 6.02 × 10²³ argon atoms in 1 mole of argon atoms.

[tex]10^{6} atom \times \frac{1 mol}{6.02 \times 10^{23}atom } = 1.7 \times 10^{-18} mol[/tex]

One million argon atoms is equivalent to 1.7 × 10⁻¹⁸ moles of argon atoms.

Answer:

THE PRESSURE OF THE TIRE ON THE TRIP HOME AT THE ROAD SURFACE TEMPERATURE OF 32°C IS 160 kPa.

Explanation:

Initial Pressure = 75 kPa

Initial temperature = 15 °C

Final temperature = 32 °C

Final pressure = unknown

Using the combined equation of gases;

P1V1/T1 = P2V2/ T2

Since the tire will have the same volume of air in it showing that volume of constant both at the repair shop and on the road surface.

The relationship between pressure and temperature is used with constant volume.

P1/T1 = P2/ T2

75 kPa / 15 °C = P2 / 32 °C

P2 = 75 kPa * 32 °C / 15 °C

P2 = 2400 kPa °C / 15 °C

P2 = 160 kPa.

So therefore, the pressure of the tire on the trip home when the temperature of the road surface is 32°C is 160 kPa.

Answer:

So the empirical formula is C14H18N2O5

Explanation:

C = 57.2% = 12g/mol

H = 6.1% = 1g/mol

N = 9.5% = 14g/mol

O = 27.2% = 16g/mol

Empirical Formula for compound hmm

Assume

C = 57.2g

H = 6.1g

N = 9.5g

O = 27.2g

So we have

C = 57.2g/12g =  4.76  moles

H = 6.1g/1g      =  6.10   moles

N = 9.5g/14g   =  0.68  moles

O = 27.2g/16g =  1.70   moles

Divide each mole value by the smallest number of moles calculated.  Round to the nearest whole number.

C =  4.76  moles / 0.68 moles = 7

H = 6.10   moles / 0.68 moles = 9

N = 0.68  moles / 0.68 moles = 1

O = 1.70   moles / 0.68 moles = 2.5

Ok so we now have the ratios but for O it's 2.5, have to be whole numbers so we will need to double all the numbers.

C = 14

H = 18

N =  2

O =  5

So the empirical formula is C14H18N2O5

The functional group that defines a ketone is =O and the correct option is option 4.

Ketones are a common functional group in organic chemistry. Ketones have important physiological properties. As a result, they are a part of several sugars and compounds involved in medicinal use such as cortisone, an anti-inflammatory.

In ketones, the carbonyl group has 2 hydrocarbon groups attached to it. These can be either the ones containing benzene rings or alkyl groups. Ketone does not have a hydrogen atom attached to the carbonyl group.

Therefore, the functional group that defines a ketone is =O and the correct option is option 4.
