Answers

Answer:

This statement is the definition of law of conservation of mass.

Explanation:

Law of conservation of mass:

According to the law of conservation mass, mass can neither be created nor destroyed in a chemical equation.

This law was given by French chemist  Antoine Lavoisier in 1789. According to this law mass of reactant and mass of product must be equal, because masses are not created or destroyed in a chemical reaction.

For example:

In given photosynthesis reaction:

6CO₂ + 6H₂O   →   C₆H₁₂O₆ +  6O₂

there are six carbon atoms, eighteen oxygen atoms and twelve hydrogen atoms on the both side of equation so this reaction followed the law of conservation of mass.

Let us consider the general chemical reaction.

What is atom?

Atom, the smallest unit of matter that may be separated without releasing electrically charged particles. It is also the tiniest unit of matter with the characteristics of a chemical substance. As a result, the atomic is the fundamental building component of chemistry.

The majority of the molecule is empty space. The rest of the structure is made up of a positive-charged nucleus of neutrons and protons surrounding by a swarm of negative-charged electrons. In comparison to electrons, the lightest charge particles in nature, nuclear nucleus is small yet dense. The atoms in the liquid would be vibrating in position.

Therefore, the correct option is option B.

in an experiment it was found that the total charge on an oil
drop was 5.93 X 10^-18 C How many negative charges does
the drop contain? (#51)

Answers

Answer:

37 negative charges.

Explanation:

We're being asked to determine how many negative charges a drop contains from an oil drop experiment where the total charge was 5.93x10-18 C. The drop contains 37 negative charges.

It was stated and identified that we are to attempt question #51 alone.

From the given information;

The total charge on an oil drop = 5.93 × 10⁻¹⁸ C

According to Oil drop experiment carried out by Robert Milliken in (1910);

In the oil drop laboratory experiment, It was possible for Him to substitute oil for water (because water quickly evaporate). Robert Milikan adjusted the electrical voltage among the two metal plates while the oil drop continues to drop until it stopped. When the drop was stopped, the gravitational downward force on the oil drop was equivalent to the electrical upward force on the charges thereby enabling Robert Millikan to be able to estimate the electrical charge drop.

Robert Milliken identified that the magnitude of a single negative electron charge is:

= 1.6 × 10⁻¹⁹ C

If in an experiment, the total charge =  5.93 × 10⁻¹⁸ C

Then;

The number of negative charges in the oil drop can be calculated as;

[tex]\mathbf{=\dfrac{5.93 \times 10^{-18}}{1.6 \times 10^{-19}}}[/tex]

= 37.063 negative charges

Therefore, we can conclude that the numbers of negative charges contained in the total drop = 37.063.

What is the total pressure of a container in kpa if the partial pressures are 1.25 atm and 66.7 psi?

Answers

Answer:

586 kpa(kilopascal/1000 pascals)

Explanation:

given 1.24 atm(standard atmosphere), and 66.7 psi(pound force per square inch).

To find the total pressure we should use dalton's law of partial pressures which is the sum of the pressures of each individual gas.

then we convert them to pascals and divide by 1000 to get the measurement in kilopascal.

knowing that 1 atmosphere is proportional to around 14.696 psi. We can multiply our given measure of atm by that and sum it by psi like so. 1.24×14.6959 = 18.22298.

Then,

18.22298+ 66.7 = 84.92298

psi.

Since 1 psi is proportional to around 6894.76 pascals. 1 psi will be 68.9476 kilopascal. 84.92298 * 6.89476 = 585.523336 ≈ 586

A new element was discovered. It’s average atomic mass was found to be 245.6 amu. Isotope #1 has a mass of 243.2 amu; isotope #2 has a mass of 244.9 amu; isotope #3 has a mass of 247.2 amu. Which isotope is most likely to be the most abundant?

A
Isotope 1

B
Isotope 2

C
Isotope 3

D
They all contribute the same amount

Answers

Answer:

B. Isotope 2

Explanation:

Isotopes can be defined as the atom of an element that has the same number of protons but different number of neutrons. This ultimately implies that, the isotopes of an element have the same atomic number (number of protons) but different atomic mass (number of nucleons).

Basically, the atomic mass of any chemical element found in the periodic table is equal to the weighted average of all its isotopes. Therefore, the isotope with the closest mass to the weighted average would be the most abundant.

In this scenario, a new element was discovered with an average atomic mass of 245.6 amu.

Isotope #1 has a mass of 243.2 amu.Isotope #2 has a mass of 244.9 amu.Isotope #3 has a mass of 247.2 amu.

Hence, the isotope which is most likely to be the most abundant is isotope #2 that has a mass of 244.9 amu because it is closest in mass to the relative atomic mass (weighted average) of 245.6 amu.

How would you expect a positive particle approaching another positive particle to behave?

Answers

Answer:

They would produce a repulsive force to another

Explanation:

A positive particle approaching another positive particle will repulse it.

According to coulomb's law "like charges repel one another and unlike charges attract".

A charge is an intrinsic property of any matter.

When like charges e.g positive and positive or negative and negative charges are in the vicinity of one another, they repel each other.

When unlike charges; positive and negative are brought together, they simply attract one another.

Therefore, we expect that a positive particle approaching another positive particle will repel one another.  

When a positive particle approaches another positive particle, the two particles repel or move away from each other.

In electrostatics we know that like charges repel while unlike charges attract. Therefore when we have two like charges, they simply move away from each other. This is known as repulsion of charges.

Hence, two positive charges approaching each other will simply move away and repel each other according to the laws of electrostatics.

Doing Calculations The metal thallium occurs naturally as 30 percent thallium-203 and 70
percent thallium-205. Calculate the atomic mass of thallium. Enter your numerical answer in
the blank provided please help

Answers

Answer:

Average atomic mass of thallium = 204.4 amu.

Explanation:

Given data:

Abundance of thallium-203 = 30%

Abundance of thallium-205 = 70%

Average atomic mass = ?

Solution:

Average atomic mass of thallium = (abundance of 1st isotope × its atomic mass) +(abundance of 2nd isotope × its atomic mass)  / 100

Average atomic mass of thallium = (30%×203)+(70%×205) /100

Average atomic mass of thallium =  6090 + 14350 / 100

Average atomic mass of thallium = 20440 / 100

Average atomic mass of thallium = 204.4 amu.

One differentiating characteristic between vascular and nonvascular plants is the lack of active transport structures in the nonvascular plants. How does the lack of xylem or phloem contribute to the smaller size of the nonvascular plants?

Nonvascular plants are smaller because xylem and phloem help a plant stand up taller.
Nonvascular plants have other transport structures that are microscopic and therefore take up less room.
Nonvascular plants rely upon concentration gradients to move food and water, which only works over small distances.
Nonvascular plants are smaller because they don’t photosynthesize as much as vascular plants and don’t get enough food.

Answers

Answer:

One of the most important characteristics of non-vascular plants is the absence of vascular tissues. Non-vascular plants do not have the vascular tissues known as xylem and phloem. ... As they do not have any vascular tissue, they cannot retain water for long time or transport it to other parts of the plant.

1)Fluorine-21 has a half life of approximately 5 seconds. If you start with 100g, how much
would remain after 10 seconds?
What’s the answr

Answers

Answer:

25 g

Explanation:

The following data were obtained from the question:

Half life (t½) = 5 s

Original amount (N₀) = 100 g

Time (t) = 10 s

Amount remaining (N) =..?

Next, we shall determine the decay constant for the disintegration. This can be obtained as follow:

Half life (t½) = 5 s

Decay constant (K) =.?

K = 0.693 / t½

K = 0.693 / 5

K = 0.1386 s¯¹

Finally, we shall determine the amount of the isotope that remained after 10 s as follow:

Original amount (N₀) = 100 g

Time (t) = 10 s

Decay (K) = 0.1386 s¯¹

Amount remaining (N) =..?

Log (N₀/N) = kt /2.303

Log (100/N) = (0.1386 × 10) / 2.303

Log (100/N) = 1.386 / 2.303

Log (100/N) = 0.6018

Take the anti log of 0.6018

100/N = antilog (0.6018)

100/N = 4

Cross multiply

100 = N × 4

Divide both side by 4

N = 100/4

N = 25 g

Therefore, the amount remaining after 10 s is 25 g

Shells

The maximum number of electrons that can be accommodated in a shell is based on the principal quantum number (n). It is represented by the formula 2n2, where ‘n’ is the shell number. The shells, values of n, and the total number of electrons that can be accommodated are tabulated below.

Shell and ‘n’ value Max. Electrons in the Electron Configuration

K shell, n=1 2*12 = 2

L shell, n=2 2*22 = 8

M shell, n=3 2*32 = 18

N shell, n=4 2*42 = 32

L shell:  n =2

hence,

2n²

= 2(2)²

i.e. 8 electrons can fit in the l shell

hence max no. of electrons is 8

so configuration in L shell is,

2, 8...
