Then as the electrons in the atoms fall back down, they emit electromagnetic radiation (light). The amount of light emitted at different wavelengths, called the emission spectrum, is shown for a discharge tube filled with hydrogen gas in Figure 12.6 below.

Alex lives in Arizona. He plants flowers in a pot with new soil mixed with fertilizers, and he places the pot on his back porch.
Anuta_ua [19.1K]
Since he’s watering it and it’s getting sun, i would say it’s because the soil isn’t rich enough and it doesn’t have the nutrients it needs for the plant to grow.

0.22 L of HNO3 is titrated to equivalence using 0.10 L of 0.1 MNaOH. What is the concentration of the HNO3?
White raven [17]

Answer:- Molarity of the acid solution is 0.045M.

Solution:- The balanced equation for the reaction of given acid and base is:

HNO_3+NaOH\rightarrow NaNO_3+H_2O

From the balanced equation, they react in 1:1 mol ratio. So, we could easily solve the problem using the equation:

M_aV_a=M_bV_b

where, M_a is the molarity of acid, M_b is the molarity of base, V_a is the volume of acid and V_b is the volume of base.

Let's plug in the given values in the equation:

M_a(0.22L)=0.1M(0.10L)

on rearranging the above equation:

M_a=\frac{0.1M(0.10L)}{0.22L}

M_a = 0.045M

So, the molarity of the acid solution is 0.045M.

Which of the following is a factor in natural selection?
Vera_Pavlovna [14]

Answer:

D.

Explanation:

Although all of these answers are similar, it seems that all three are the answer. I am sorry if the answer ends up being B but I'm pretty sure the answer is D. Charles Darwin's evolution theory "evolved", get it, from the natural selection theory. The theory is described as "the process whereby organisms better adapted to their environment tend to survive and produce more offspring." However, some factors that effect natural selection are competition, selection and variation. I believe all three fit the answer and therefore I believe answer D is correct.
