Under a certain set of conditions, the percent yield of a reaction that produces carbon dioxide is 75.0%. What mass in grams of CO2 will actually be recovered if the theoretical yield is 26.7 grams?

Answer:

Photosynthesis, process by which green plants and certain other organisms use the energy of light to convert carbon dioxide and water into the simple sugar glucose. In so doing, photosynthesis provides the basic energy source for virtually all organisms.

Answer:

Greater

Explanation:

The amplitude of a wave is the height of the wave or the vertical displacement of the wave motion. We determine a wave amplitude usually by looking at the graph of the wave.

Amplitude is directly proportional to the energy of a wave. The higher the amplitude of a wave, the more its energy.

Frequency is the number of waves that passes a point at a particular instance of time. It is also directly proportional to the energy carried by a wave. The higher the frequency of a wave, the greater its energy.

Answer:

This question is incomplete

Explanation:

This question is incomplete. However, the beaker that contained some water before NaOH were added means that the resulting solution in that beaker will be more dilute. When this diluted sodium hydroxide solution is added to HCl (not hci), the reaction below occurs

HCl + NaOH ⇒ NaCl + H₂O

The reaction above is a neutralization reaction. The concentration of the acid (HCl) will reduce when a base (sodium hydroxide) is added and will also reduce more because of the presence of more water (in the base) which normally reduces the concentration of ions present in an acid or a base to become more dilute.

The layers of the earth were formed due to the sediments that significantly flattens out beside the center of the earth. After a long duration, a new layer is spread over the older layer, and so on.

The different layers of the earth are as follows:

The above-mentioned layers of the earth were formed with the impact of the building blocks of the earth that are remarkably known as Planetesimals, collided, and collapsed.

During that time, the hardest elements like nickel, iron, etc. constitute the core while the lighter elements like carbon, oxygen, silicon, etc. play an essential role in the formation of crust and mantle.

Therefore, the layers of the earth were formed due to the sediments that significantly flattens out beside the center of the earth.

Answer:

1 g

Explanation:

The following data were obtained from the question:

Original amount (N₀) = 32 g

Time (t) = 71.5 days

Half-life of phosphorus (t½) = 14.3 days

Amount remaining (N) =?

Next, we shall determine the rate of disintegration. This can be obtained as follow:

Half-life of phosphorus (t½) = 14.3 days

Decay constant (K) =?

K = 0.693 / t½

K = 0.693 / 14.3

K = 0.0485 /day

Finally, we shall determine the amount remaining as illustrated below:

Original amount (N₀) = 32 g

Time (t) = 71.5 days

Decay constant (K) = 0.0485 /day

Amount remaining (N) =?

Log (N₀/N) = Kt/2.303

Log (32/N) = 0.0485 × 71.5 / 2.303

Log (32/N) = 3.46775 / 2.303

Log (32/N) = 1.5058

Take the antilog of 1.5058

32/N = antilog (1.5058)

32/N = 32.05

Cross multiply

32 = N × 32.05

Divide both side by 32.05

N = 32 / 32.05

N = 0.998 ≈ 1 g

Thus, the amount remaining after 71.5 days is approximately 1 g.

The half-life of a radioactive substance refers to the time taken for the substance to Decay to half of its initial size. Hence, the mass of the substance left after 71.5 days is 1 gram.

After 14.3 days ;

After 14.3 × 2 = 28.6 days :

After 14.3 × 3 days = 42.9 days :

After 14.3 × 4 days = 57.2 days :

After 14.3 × 5 days = 71.5 days :

Hence, the mass of the sample left after 71.5 days would be 1 gram.

Explanation:

There will be three peaks. The relative masses of each of the peaks is shown below;

1H - 1H peak will have a mass of 2*1.00783 amu = 2.01566 amu

1H -2H peak will have a mass of 1.00783 amu + 2.01410 amu = 3.02193 amu

2H - 2H peak will have a mass of 2*2.01410 amu = 4.0282 amu

The 2H - 2H peak is the smallest while 1H - 1H peak is the largest.

Answer:

Ar, P, Si, Mg, Na

Explanation:

Ar=106pm

P=107pm

Si=111pm

Mg=141pm

Na=166pm

Na>Mg>Si>P>Ar is the order of increasing atomic radius.

Elements are the simplest substances which cannot be broken down using chemical methods.

Atomic radii vary in a predictable way along or across the periodic table. The atomic radius increases from top to bottom in a group, and decreases from left to right across a period. Thus we can say that helium is the smallest element, and francium is the largest.

Ar=106pm

P=107pm

Si=111pm

Mg=141pm

Na=166pm

Hence, Na>Mg>Si>P>Ar is the order of increasing atomic radius.
