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.

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.

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.

Answer:

Ores mined from shields.

Explanation:

Ores mined from shields are the source from which we get the history of Precambrian rocks. The Ores from shield experience the Precambrian era so that's why its rocks provides information about that era. The Precambrian supereon is the division of the geological time scale which is the first and longest stage in the history of the Earth which also includes the Hádic, Archaic and Proterozoic eons.

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.

Answer:

CaCO3 + H2O

Step by step explanation

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.

Answer:

height(h)=10 m

acceleration due to gravity (g)=10 m/s^2

mass (m)=?

potential energy=67

or,mgh= 67

or,m×10×10=67

or,m=67/100

or,m=0.67 kg

Therefore,m= 670 grams

dipole: dipole interactions

- dispersion forces (London forces)

- hydrogen bonds

as the attractive forces between molecules becomes larger, it takes more energy to separate them

- as a result, vapor pressures, boiling points and melting points will be larger

occur between molecules that have a permanent dipole moment

- H-Cl----H-Cl

Answer:

since an oxygen atom normally has 8 protons and 8 electrons, this ion has 10 electrons (-10 charge) and 8 protons (+8 charge) giving it a charge of -2 (-10 + 8 = -2).

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

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]
