What do atoms form when they bond chemically?a. atom
b. mixture
c. solution
d. molecules

Answers

Answer 1

Answer: They form molecules which can be in solution form if diluted in water, but some do form solutions on exposure to the atmosphere i.e they are deliquescent like pellets of sodium hydroxide

Changing the pressure of a system has the highest effect on a substance in which phase?a. gas
b. solid
c. liquid
d. plasma

Answers

The best answer to the question presented above would be letter a. Changing the pressure of a system has the highest effect on a gaseous phase. Solids and liquids under pressure make little difference, while gas molecules have many behaviors due to change in pressure.

The ph of a buffer does not depend much on the concentrations of its acid–base conjugate pair because

Answers

Answer:

It could react with the present hydride or hydroxile ions.

Explanation:

Hello,

One the main features of buffers, is that when the acid-base conjugates are formed they could react with the added $H^+$ or $OH^(-1)$ in order to keep the pH as constant as its buffer capacity allows it.

Best regards.

Final answer:

A buffer solution maintains a stable pH primarily through the action of its acid-base conjugate pair reacting to counter changes, a property known as buffer capacity. High concentrations increase buffer capacity, allowing more acid or base to be neutralized. However, exceeding the buffer capacity can lead to pH changes.

Explanation:

The pH of a buffer solution doesn't greatly depend on the concentrations of its acid-base conjugate pair as the buffer's job is to keep the pH relatively constant. This is achieved by having appreciable amounts of its weak acid–base pair in the solution. If a strong acid or base is introduced into the system, the buffer pair reacts to counteract these changes. This is called buffer capacity.

For instance, consider a buffered solution composed of acetic acid and its conjugate base, acetate. The system can resist changes in pH upon addition of small quantities of an acid or base. This is because acetic acid and acetate can consume small additions of hydrogen ions (from an acid) or hydroxyl ions (from a base), keeping the overall pH stable.

When concentrations of the acid-base pair are high, the buffer capacity increases and hence more amounts of acid or base can be neutralized without a significant change in pH. However, there are limits to this capacity. If excessive amounts of acid or base are added, they may exceed the buffer's capacity, and its acid/base pairs will be either largely consumed or overrun, leading to changes in pH.

Which explains why the lawsmotion are scientific laws?
O A. The theories of motion became laws after there was enough
evidence to prove they were true.
O B. The laws cannot be tested by experiments, but scientists know
that they are correct because they make sense mathematically.
c. The laws explain how objects move and are supported by
experimental evidence.

Answer:

Explanation:

Scientific laws describe how things work with little to no exception. They do NOT provide an explanation to WHY something occurs.

Answer:

The answer is D because scientific laws describe how things work not why they happen.

What two aspects of a force do scientists measure?a. position and size
b. size and stability
c. magnitude and direction
d. strength and magnitude

Answers

Answer: option c. magnitude and direction

Explanation:

1) Force is a vector: it has magnitude and direction.

2) Magnitude measures the "intensity" of the force. It is measured in newtons (N), in the SI (international system of units). One newton is the force exerted to confere an acceleration of 1 m/s² to a mass of 1 kg.

3) Telling the magnitude of the force is not enough information to understand what the force is and to predict its effect.

It is necessary to tell the direction in which the force is applied.

It is not the same a force of 10 N that pulls that the same magnitude pushing. And it is not the same a hhorizontal force of 100 N to move an object, than the same magnitude applied at an agle.

That is why the force must be measured and reported as a magnitude and a direction.

4) Examples of forces correctly reported are:

i) 100 N vertically upward

ii) 1000 N 20° to the east of the north.

iii) 0.2 N with an elevation angle of 50°.

Then, scientists must measure the magnitude and the direction of the force.

1. The answer is C.
It is the magnitude and the direction that the scientist considered to measurethe aspect of force.
=> Magnitude can be describe in 3 terms.
In mathematics it is considered as the relative size of an object.
IN Astronomy, it is considered as the measure of brightness and differences ofbrightness in astronomy study
And in earthquake, it is a measure of the energy of earthquake.
=> Direction is a course or anexplicit instruction where a certain object move.

How many valence electrons does carbon have

Answers

Answer:

Carbon has 4 valence electrons

Explanation:

The valence electrons are those found in the last energy level of the atom.

They are responsible for the interaction between atoms,

they can form bonds.

Let's see the electronic configuration of carbon.

The atomic number of C is 6 (Z=6)

$C= 1S^2 2S^2 2P^2$

To know the number of valence electrons that we have we count in the last energy level of the atom.

The last energy level of carbon is 2 and we 4 electrons is this level.

So carbon has 4 valence electrons.

Final answer:

Carbon, as an element from Group 14 of the periodic table, has four valence electrons. These electrons are the ones available for bonding and are located in its outermost shell.

Explanation:

Carbon belongs to Group 14 in the periodic table and has four valence electrons. These are the electrons that are available for bonding. Elements in Group 14 have four electrons in their outermost shell because the s and p sublevels can hold up to four electrons. For example, in the case of carbon, its electron configuration is 1s22s22p2 which clearly shows the four valence electrons in the outermost shell (the 2s and 2p orbitals).
