What controls the DNA molecule?
Answer:
nucleotides
Explanation:
The four types of nitrogen bases found in nucleotides are: adenine (A), thymine (T), guanine (G) and cytosine (C). The order, or sequence, of these bases determines what biological instructions are contained in a strand of DNA. ... DNA is made of chemical building blocks called nucleotides.

EMERGENCY HELP ME OUT
Answer:
D, The volume will be multiplied by a factor of 4
Explanation:
First find the height
V = π(r^2)h
Plug in what we know
83 = π(3^2)h
83 = π(9)h
83 = (9π)h
9[tex]\pi[/tex] = 28.27
83/28.27 = (28.27)h/28.27
h = 2.94
Then find the volume of the new can by doubling the radius
3 x 2 = 6
r = 6
V = π(r^2)h
V = π(6^2)2.94
V = π(105.84)
V =332.51
For the first one, they rounded to the nearest whole #, so let's do the same.
V = 333
Then divide 333 by 83 to get 4
Therefore, the volume will be multiplied by a factor of 4

A scientist plans the react 9.0x10^-2 L NO held at a pressure of 200.0kPa and a temperature of 20.0 C with excess hydrogen. How many moles of nitrogen gas will be produced
Answer:
[tex]n_{N_2}=0.00369molN_2[/tex]
Explanation:
Hello there!
In this case, by firstly setting up the described chemical reaction, we are able to write:
[tex]2NO(g)+2H_2(g)\rightarrow N_2(g)+2H_2O(g)[/tex]
Thus, given the pressure (convert to atm), volume and temperature (convert to K) we can calculate the moles of NO:
[tex]n=\frac{PV}{RT}\\\\n=\frac{200.00/101.325atm*0.090L}{0.08206\frac{atm*L}{mol*K}*(20.0+273.15)K} \\\\n=0.00738molNO[/tex]
Next, we use the 2:1 mole ratio of NO to N2 to obtain the moles of nitrogen gas that will be produced:
[tex]n_{N_2}=0.00738molNO *\frac{1molN_2}{2molNO} \\\\n_{N_2}=0.00369molN_2[/tex]

To determine the molar mass of an element, one must know the element's
a. number of isotopes.
b average atomic mass
c avogradro constant
d atomic number
Answer:
d
Explanation:
from you know the atomic number it should be easy to find
To determine the molar mass of an element, one must know the element's atomic number. Therefore, option D is correct.
What is the atomic number ?An element's atomic number (Z) is the number of protons in the nucleus of each atom of that element. This means that the number of protons is the feature that distinguishes each element from all others. Elements differ based on their atomic number.
Because the combined masses of protons and neutrons account for nearly all the mass of a given atom, the atomic mass of a single atom can be calculated by adding the total number of protons and neutrons of that particular isotope.
The atomic mass of any element on the periodic table can be used to calculate its molar mass.
Thus, option D is correct.

The piston of an internal combustion engine
compresses 218 mL of gas. The final pressure
is 15 times greater than the initial pressure.
What is the final volume of the gas, assuming
constant temperature?
Answer in units of mL.
Answer:
14.53ML
Explanation:
V1=218
V2=?
P2=15p1
USING BOYLE'S LAW
P1V1=P2V2
V2=P1V1/P2=P1(218ML)/15P1
=14.53ML

Provide one example where a neutralization reaction is undesired/harmful. State the reactants and explain why it is harmful for this reaction to take place.
Answer:
You're in my science class wth
Explanation:
For instance farmers are using basic fertilizers to neutralize an acid soil –which is harmful for the plants- while basic solutions are added in the chimneys of factories to neutralize the acid smoke that they produce –avoiding the catastrophic effects of the acid rains. Acid released in the environment from industry creates acid rain which has many ecological effects. Acid rain makes waters acidic, and causes them to absorb the aluminium that makes its way from soil into lakes and streams. This combination makes waters toxic to crayfish, clams, fish, and other aquatic animals.

What is the new concentration of a solution of CaSO3 if 10.0 mL of a 2.0 M CaSO3 solution is diluted to 100 ml?
Answer: The new concentration of a solution of [tex]CaSO_{3}[/tex] is 0.2 M 10.0 mL of a 2.0 M [tex]CaSO_{3}[/tex] solution is diluted to 100 mL.
Explanation:
Given: [tex]V_{1}[/tex] = 10.0 mL, [tex]M_{1}[/tex] = 2.0 M
[tex]V_{2}[/tex] = 100 mL, [tex]M_{2}[/tex] = ?
Formula used to calculate the new concentration is as follows.
[tex]M_{1}V_{1} = M_{2}V_{2}[/tex]
Substitute the values into above formula as follows.
[tex]M_{1}V_{1} = M_{2}V_{2}\\10.0 mL \times 2.0 M = M_{2} \times 100 mL\\M_{2} = 0.2 M[/tex]
Thus, we can conclude that the new concentration of a solution of [tex]CaSO_{3}[/tex] is 0.2 M 10.0 mL of a 2.0 M [tex]CaSO_{3}[/tex] solution is diluted to 100 mL.
