Answer 1

Answer:

Metaphase is the third phase of mitosis, the process that separates duplicated genetic material carried in the nucleus of a parent cell into two identical daughter cells. Long protein filaments called kinetochore microtubules extended from poles on either end of the cell and attached to the kinetochores.

Two isotopes of the same element must have the same
A. O atomic symbol and number of neutrons.
B
atomic mass and number of neutrons.
C.
atomic symbol and number of protons.
D
atomic
and number of protons.

Answers

Answer:

C. atomic symbol and number of protons.

Explanation:

number of protons in the nucleus, but differ in the number of neutrons. The nucleon number is equal to the total number of protons and neutrons in the nucleus. ... The atomic mass number A is equal to the total number of protons and neutrons.

Two isotopes of the same element must have the same atomic symbol and number of protons.

ISOTOPES:

Isotopes are atoms of the same element with the same atomic number and chemical identity but different atomic masses.

The forms in which atoms of a particular element exists is referred to as its isotope.

The sole difference between isotopes of the same element is the number of neutrons each contain, which is responsible for the difference in masses.

This means that isotopes of the same element must have the same atomic symbol and number of protons. For example, Carbon has two isotopes namely: C- 14 and C- 12 with both possessing atomic number 6 and symbol C.

A sample of unknown concentration is diluted by placing 0.2 mL into 9.8 mL of buffer and then 3 mL is placed into a standard 1x1 cm square cuvette. It is measured at 350 nm and the Abs is 0.3. The molar absorptivity is 12.3 L/mol*cm. What is the concentration of the undiluted sample (mol/L to 2 decimal places)?

Answers

Answer:

The answer is "[tex]4.875 \ \frac{mol}{l}\\[/tex]".

Explanation:

The molar absorptivity value is=  12.3    [tex]\frac {L}{mol \times cm}[/tex]

path length of cell = 1  [tex]\ cm[/tex]

Absorbance = 1.2

Using the beer's lambert law:

[tex]A = \varepsilon \ cl\ \ \ \ \ \ \ _{where} \\\\c= \frac{A}{ \varepsilon l } \\\\[/tex]

  [tex]= \frac{1.2}{12.3 \times 1}\\\\= 0.0975 \ \frac{mol}{L}\\[/tex]

Claculating the concentration of the solution after dilution: [tex](m_2)= 0.0975 \ \ \frac{mol}{L}[/tex]

find out the dilution value before concentration :

The volume taken by the dilution: [tex](V_1) = 0.2\ ml[/tex]

The final volume after dilution:

[tex](V_2) = 9.8+0.2\\[/tex]

       [tex]= 10 \ ml[/tex]

Formula:

[tex]\bold{M_1 \times V_1 = M_2 \times V_2} \\\\ M_1= \frac{M_2 \times V_2 }{V_1}\\\\[/tex]

     [tex]= \frac{ 0.0975 \times 10 }{0.2}\\\\= \frac{ 0.975 }{0.2}\\\\ = 4.875 \ \frac{mol}{l}\\[/tex]

What is an example of reactivity?
A. A piece of paper being torn
B. A nail heating up
C. An ice cube melting
D. A bicycle rusting

Answers

Answer:

D. A bicycle rusting.

Explanation:

A. is incorrect because tearing a piece of paper is a physical change, not a chemical change.

B. is incorrect because we are just heating up the object. That only changes how fast the particles are moving and the change in state of matter.

C. is incorrect because we are adding heat to change a state of matter (from solid to liquid) and it is a physical change.

Therefore, only D. is the correct answer. Iron rusts, and when it does, it chemically changes into an iron oxide (rust).

Answer:

Im pretty sure that it’s D.
