Answer: D. It increases from top to bottom on an H-R diagrams 

<span>Luminosity is defined in the wordbook as brightness of a celestial object. In astronomy, it stands for the total amount of energy emitted per unit time by a star, so C. is correct. It is measured in joules per second or watts so A is correct also. It is B,  valued at 1 for our sun. </span>

In an H-R  diagram, the energy of a star is plotted on the vertical axis. The lower or more negative the measure, the brighter the star, D is therefore not true.

Calculate the volume of 1 M NaOH needed to prepare 12.0 mL of a 0.10-M solution. Prepare this solution. (Refer to the Dilutions
Lapatulllka [165]

Answer:

1.2 mL

Explanation:

<em>This is a problem of simple dilution. The dilution principle simply agrees that the number of moles before dilution must be equal to the number of moles after dilution.</em>

Recall that: number of moles = mass/molar mass or molarity x volume.

Hence, for the dilution principle:

              initial molarity x initial volume = final molarity x final volume.

In this case, initial molarity of NaOH = 1 M, initial volume = ?, final molarity = 0.1 M, final volume = 12.0 mL.

Initial volume = final molarity x final volume/initial molarity

                       = 0.1 x 12/1 = 1.2 mL

It thus means that 1.2 mL of 1 M NaOH would be taken and then diluted up to 12.0 mL mark by the addition of distilled water in order to produce 12.0 mL, 0.10 M NaOH solution.

Cerrena [4.2K]

Answer:

This statement is False.

Explanation:

A shared apo-morphy which differentiate a clade from other organisms is called synapomorphy. In simple words, members of monophyletic group shares an apomorphy which indicate the presence or absence of certain organs from clade.

For example, loss of legs in snakes is an important  synapomorphy.
