What can you infer about the growth of the seed type pictured in the graphs below? ( Note, the vertical axis represents the numb

er of seeds )
The graph shows Time in days from 0 to 5 on the x-axis and 0 to 100 on the y-axis with 5 percent light. Day 0 there are 100 seeds and 0 sprouts. The number of seeds and sprouts remains the same through 2.5 days. Then the number of seeds decreases while the number of sprouts increases. Day 5 there are 30 seeds and 70 sprouts.The graph shows Time in days from 0 to 5 on the x-axis and 0 to 100 on the y-axis with 80 percent light. Day 0 there are 100 seeds and 0 sprouts. The number of seeds and sprouts remains the same through 2.5 days. Then the number of seeds decreases while the number of sprouts increases. Day 5 there are 30 seeds and 70 sprouts.
a.
More seeds grow with more light.
b.
More seeds grow with less light.
c.
The seeds grow faster with more light.
d.
Light has no effect on seed growth.

It is desired to make 1.00 liter of 6.00 M nitric acid from concentrated 16.00 M HNO3.A) How many moles of nitric acid are in 1.
natima [27]

Answer:

A) 6.00 mol.

B) 0.375 L or 375 mL

C) 6.00 M

Explanation:

Hello,

A) In this case, from the definition of molarity, we compute the moles for the given volume and concentration:

n=M*V=1.00L*6.00mol/L=6.00mol

B) In this case, from the stock solution, the required volume is:

V=\frac{6.00mol}{16.00mol/L}=0.375L

C) In this case, we apply the following formula for dilution process:

M_1V_1=M_2V_2

Thus, solving for the final molarity, we obtain:

M_2=\frac{M_1V_1}{V_2}=\frac{16.00M*0.375L}{1.00L}\\  \\M_2=6.00M

Regards.

snow_lady [41]

Answer:

The higher the temperature, the more soluble most ionic solids are in water

As you cool a saturated solution from high temperature to low temperature, solids start to crystallize out of solution if you achieve a supersaturated solution.

If you raise the temperature of a saturated solution, you can (usually) add more solute and make the solution even more concentrated.

Explanation:

For many ionic solids, solubility in water increases with increase in the temperature of the solution.

This implies that increasing the temperature allow more solute to dissolve in the solvent, supersaturation may be achieved by so doing. As the solution is cooled, the solid crystalizes out of solution hence the answers above.

Romashka-Z-Leto [24]

Answer:

<u>Aristotle's Model :</u>

geocentric

planets fixed on nested spheres

<u></u>

<u>Ptolemy's model:</u>

geocentric

planets fixed on epicycles

accurately predicted the positions of the planets

Explanation:

Let's begin by the fact both models are geocentric  and make a brief explanation of them:

<u></u>

<u>Aristotle's Model :</u>

Aristotle built his model based on observations and philosophical assumptions, not on measurements or calculations, then he mistakenly thought the Earth was the center of the universe.

So, according to this model, the universe was spherical and finite, with the Earth immobile at its center, composed of the four fundamental elements (made up of spherical layers): <em>ground, water, air and fire</em>; and the Sun along with the fixed planets in their respective concentric spheres (also called nested spheres) revolving around the Earth.

<u>Ptolemy's model:</u>

Ptolemy's model of the universe was also geocentric, placing the Earth motionless in the center of the known universe and was the accepted model for a long time during the Middle Ages.

In this sense, ccording to Ptolemy's model of the universe our planet remains stationary while the other planets, the Moon and the Sun describe complicated orbits around it (called epicycles).

However, this model predicted with an acceptable accuracy for that time the motion of the known planets, until Copernicus appeared with the revolutionary Heliocentric model.
