how does this data provide evidence for base pairing in dna

Answer: Well, a mole is really the same thing. For a chemist, a mole conjures up the number 6.02 times 10 to the 23rd, not a fuzzy little animal. The only difference is that the other quantities are more familiar to us. Lol

A nuclear equation is one, where the sum of the mass numbers and the sum of the atomic numbers balance on either side of an equation. Nuclear equation problems will often be given such that one particle is missing.

Answer:

Explanation:

All chemical reactions involve energy. Energy is used to break bonds in reactants, and energy is released when new bonds form in products. Endothermic reactions absorb energy, and exothermic reactions release energy. The law of conservation of energy states that matter cannot be created or destroyed.

Rusting is the process of corroding metallic parts by the action of water and air. Iron forms iron oxide by reacting with water or air.

Rusting is the process of corrosion of  metallic parts by forming a red oxide film on the surface of the metals containing Fe.  Metals on reacting with water or air destroys by the action of oxygen.

Mostly iron and copper undergo corrosion. Corrosion is an electrochemical process by which the metal part undergo reduction and deposits in cathode.

Iron easily undergo corrosion forming rust or the red colored iron oxide. Iron react with water through air or water and forms iron oxide on the metal surface which eventually cover the whole metal.

Answer:

Gravitational potential energy is a direct function of weight and height. Higher the object, high is the gravitational potential energy.

Therefore the skydiver inside of the plane has high gravitational potential energy than the same diver after she has jumped because height is now decreased as he is going down.

Answer:

An object that goes up a hill will be going at a slower speed at the top than at the bottom of the hill. This is because moving up or down a hill changes one kind of energy into another. Objects at the bottom of the hill have more kinetic energy, which means they are moving faster.

Explanation:

Answer: The newly occupied volume is 11.46 L

Explanation:

Boyle's Law: This law states that pressure is inversely proportional to the volume of the gas at constant temperature and number of moles.

[tex]P\propto \frac{1}{V}[/tex]     (At constant temperature and number of moles)

[tex]P_1V_1=P_2V_2[/tex]  

where,

[tex]P_1[/tex] = initial pressure of gas  = 0.999 atm

[tex]P_2[/tex] = final pressure of gas = 0.802 atm

[tex]V_1[/tex] = initial volume of gas  = [tex]9.20 L[/tex]

[tex]V_2[/tex] = final volume of gas  = ?

[tex]0.999\times 9.20=0.802\times V_2[/tex]  

[tex]V_2=11.46L[/tex]

Therefore, the newly occupied volume is 11.46 L

Answer:Matter is made up of only charged particles.

Explanation: Took the test

Answer:

5.52atm

Explanation:

Using the pressure law formula:

P1/T1 = P2/T2

Where;

P1 = initial pressure (atm)

P2 = final pressure (atm)

T1 = initial temperature (K)

T2 = final temperature (K)

According to the question, the following information were provided;

P1 = 4.72 atm

P2 = ?

T1 = -3.50°C = -3.50 + 273 = 269.5K

T2 = 42°C = 42 + 273 = 315K

Using P1/T1 = P2/T2

4.72/269.5 = P2/315

CROSS MULTIPLY

4.72 × 315 = 269.5 × P2

1,486.8 = 269.5P2

P2 = 1,486.8 ÷ 269.5

P2 = 5.52atm

Answer:

67.5 gm H2O

Explanation:

2 H2   = 4 gm

O2 = 32 gm

2 H20 = 36 gm

so   32 gm O2   results in 36 gm H20

32/36  = 60/x     x = 67.5 gm

C: The atoms involved in the chemical reaction

Explanation:

In a chemical reaction, when we balance it up, the number of moles or atoms on the left side must equal that on the right hand side. And thus, the mass is found in the atoms involved in such chemical reaction.

Answer: pretty sure its 0.214 moles * 40.3g/mole = 8.6g (2 sig figs) of MgO, and

0.035 moles * 40.3g/mole = 1.4g of MgO

Answer:

See explanation

Explanation:

The valence shell electron pair repulsion theory states that; the number of electron pairs present on the valence shell of the central atom in a molecule is the final determinant of shape of the molecule.

Based on this theory, the electron domain geometry of a molecule having 4 outer atoms and 1 lone pairs on the central atom should be based on a trigonal bipyramid. The molecular geometry of this molecule is see saw with a bond angle of <90 degrees(axial) and <120 degrees(equatorial).

Answer:

D

Explanation:

7 is neutral on a PH scale. Anything less is an acid and anything higher is a base. A Ph scale goes from 1-13. 8.4-7=1.4. This is a small change so it is considered a weak base. Can I get brainliest?

Answer:

D.A weak base

Explanation:

The pH of a weak base falls somewhere between 7 and 10. Like weak acids, weak bases do not undergo complete dissociation; instead, their ionization is a two-way reaction with a definite equilibrium point. While strong bases release hydroxide ions via dissociation, weak bases generate hydroxide ions by reacting with water. Ammonia (NH3) and methylamine (CH3NH2) are examples of weak bases.

Answer:

A.)neutral

because their ions have equal and opposite charges whose resultant charge is zero
