3. Which of the following provides the best explanation for why the water drop does not slide off the inclined plane?
90 80 70
50
40
30

O A The polar water molecules are absorbed by the underlying surface.
OB The polar water molecules cause the surface to become temporarily charged, causing adhesion
OC The polar water molecules exert strong cohesive forces on one another
OD. The polar water molecules are repelled by the nonpolar surface

Answers

Answer:

The polar water molecules exert strong cohesive forces on one another

Explanation:

The forces of cohesion refer to the strong attractive forces that molecules of a substance exert on each other.

This strong attractive force keeps the molecules of the water together and causes the water molecules to be pulled inside towards each other. We refer to this phenomenon as surface tension.

Hence, due to surface tension, water does not run off an inclined plane.

Which statement is correct?

Natural processes happen spontaneously when they decrease the entropy of a system because entropy increase is counteracted by the flow of enthalpy from high temperatures to low temperatures.
Among solids, liquids, and gases, solids generally have the highest entropy because solid particles are the least mobile, and entropy is inversely related to mobility of particles.
Any change that increases the number of particles in a system increases entropy because it increases the randomness and disorder of the system.
Dissolving table salt (NaCl) in water leads to a decrease in entropy because salt particles, which are numerous individual crystals in solid form, become a homogenous solution in water.

Among solids, liquids, and gases, solids generally have the highest entropy because solid particles are the least mobile, and entropy is inversely related to mobility of particles.

Answer:

Any change that increases the number of particles in a system increases entropy because it increases the randomness and disorder of the system.

Explanation:

Imagine dropping a glass pitcher on a hard surface. The pitcher breaks into numerous shards. If the shards were collected and dropped again, they would tend to break into smaller shards; they would not reassemble themselves into a pitcher. In the universe, there is a tendency for order to be replaced with disorder. This tendency is related to a concept called entropy. The formal definition of entropy is a measure of the degree of randomness and disorder in a system.

definition of atomic number ​

Answers

The atomic number or proton number (symbol Z) of a chemical element is the number of protons found in the nucleus of every atom of that element. The atomic number uniquely identifies a chemical element. It is identical to the charge number of the nucleus. In an uncharged atom, the atomic number is also equal to the number of electrons.

Answer:

its basically represents the number of protons in the nucleus which in a neutral atom equals the number of electrons outside the nucleus and that determines the place of the element in the periodic table

Neutral atoms of neon with atomic
number 10 have the same number of
electrons as
a o²+
b ca²+
c​

Answers

Answer:

d. Mg²⁺

Explanation:

c. K⁺

d. Mg²⁺

Based on the Bohr's atomic model, the atom has electrons (Mass 0; Charge -1), protons (Mass 1; Charge +1) and neutrons (Mass 1; Charge 0).

The atomic number is equal to the number of protons. That means there are 10 protons. As the Neon is netural, the amount of electrons must be 10.

A neutral atom of Mg has 12 electrons, that means the Mg²⁺ has 10 electrons the same than Ne.

Right option is:

d. Mg²⁺

How many atoms does 9.3 moles of Mo represent?

Answers

Answer:

5.60 × 10²⁴ Mo atoms

Explanation:

The number of atoms can be found by using the formula

N = n × L

where n is the number of moles

N is the number of entities

L is the Avogadro's constant which is

6.02 × 10²³ entities

We have

N = 9.3 × 6.02 × 10²³

We have the final answer as

A, B, and D are all valid uses of a model. C is incorrect; experiments can certainly be conducted wholly apart from models.

If 4.00 moles of gasoline are burned, what volume of oxygen is needed if the pressure is 0.953 atm, and the temperature is 35.0°C?

Answers

Answer:

1325 L

Explanation:

For this excersise we assume gasoline as an octane.

The combustion is:

2C₈H₁₈  +  25 O₂ →  16 CO₂  +  18H₂O

2 moles of octane react to 25 moles of oxygen, according to stoichiometry.

If we have 4 moles of gasoline, we need (4 . 25)/2 = 50 moles of oxygen.

We can apply the Ideal Gases Law to solve this.

We convert T° to Absolute Value

35°C + 273 = 308K

P . V = n . R . T

V = (n . R . T) / P → (50 mol . 0.082 mol.K/L.atm . 308K) / 0.953 atm

Volume = 1325 L

When Svante Arrhenius first proposed his acid base theory, he was a doctoral candidate. His professors thought his ideas were unfounded. Within a decade, the Arrhenius theory of acid base was widely accepted and praised within the scientific world. Arrhenius defined acids as compounds having an ionizable hydrogen and bases as compounds with ionizable hydroxides. Eventually scientists adopted a broader theory which includes more compounds to define acids and bases. The Bronsted-Lowry acid base theory defines an acid as a _______ and a base as a ______________.

Answer:

proton donar

proton acceptor

Explanation:

From the given information of the question, Arrhenius acid and base concept is explained, from which a better term to define an acid and base is defined, known as The Bronsted-Lowry acid base theory.

According to The Bronsted-Lowry acid base theory -

An acid is the species which can readily donate a proton, where as, a base is the species, which can readily accept a proton.

Hence, the correct answer is as follow -

proton donar

proton acceptor
