What kind of pattern can you see about elements in the same period with respect to electron
structures?

Answers

Answer: A pattern of same atomic orbitals can be seen about elements in the same period with respect to electron structures.

Explanation:

The horizontal rows in a period table are called periods.

Elements present in the same period will have same atomic orbitals.

For example, electronic distribution of Na is 2, 8, 1 and it is a third period element.

Similarly, electronic distribution of Cl is 2, 8, 7 and it is also a third period element.

Hence, both Na and Cl will have K, L, M shells, that is, they have three atomic orbitals.

Thus, we can conclude that a pattern of same atomic orbitals can be seen about elements in the same period with respect to electron structures.

Answer:

The offspring are all black eye colored.

Explanation:

Since we have genes BB for black eye color and genes bb for brown eye color, crossing the genes, the resulting genotypes in the offspring is Bb, Bb, Bb and Bb. We note that all the genes have the dominant B gene. Since the black eye color dominant gene is present in all the offspring, the offspring are thus all black-eye colored.

So, If you will cross a parent with black eye color (BB) and the other is

brown eye (bb), the offspring are all black eye colored.

What is the final velocity of a 3 kg object that starts with a 5 m/s velocity due to a 2 N force acting over 3 seconds?

Answers

Answer:

V= 13 m/s

Explanation:

We're asked to find the magnitude of the object's velocity after a force is applied for

3

parallel to its motion.

We'll call the direction it's moving the positive

y

(It's moving at

We know the object's mass is

to find the

No acceleration was applied in the

Explanation:

You have 2.7 moles of carbon. How many atoms do you have?

Answers

Answer:

1.63 × 10²⁴ atoms.

Explanation:

To calculate the number of atoms (N) contained in 2.7moles of carbon, we multiply the number of moles (n) by Avogadro's number (6.02 × 10²³).

That is, N = n × nA

Where;

N = number of atoms

n = number of moles (mol)

nA = Avogadro's numbe

N = 2.7 × 6.02 × 10²³

N = 16.254 × 10²³

N = 1.63 × 10²⁴ atoms.

Hence, there are 1.63 × 10²⁴ atoms in 2.7moles of Carbon.

In a mass spectrum, there are two peaks, one at m/z 63.0 with percentage abundance 69.1% and another peak at m/z 65.0 with percentage abundance 30.9%. Determine the relative atomic mass (Ar) for this element, giving the answer to 3 significant figures (no units required).

Answers

Explanation:

hope the picture above help u understand:)

The relative atomic mass (Ar) of this element is approximately 63.6 (to three significant figures).

To determine the relative atomic mass (Ar) of the element, we use the following formula:

Ar = (m₁ × % abundance1 + m₂ × % abundance2) / 100

Where:

m₁ and m₂ are the masses of the isotopes (peaks) in the mass spectrum,

% abundance1 and % abundance2 are the percentage abundances of the corresponding isotopes.

Given information:

Peak at m/z 63.0 with a percentage abundance of 69.1%.

Peak at m/z 65.0 having a percentage abundance of 30.9%.

Calculate the weighted average mass of the element's isotopes.

Ar = (63.0 × 69.1 + 65.0 × 30.9) / 100

Ar = (4347 + 2009.5) / 100

Ar = 6356.5 / 100

Ar ≈ 63.565

Noe, let's round the calculated mass to three significant figures.

Ar = 63.6

So, the relative atomic mass (Ar) of this element is approximately 63.6 (to three significant figures). This means that the average mass of the element's atoms is approximately 63.6 times the mass of one-twelfth of a carbon-12 atom, which is the standard reference for atomic masses.

In every experiment, there must be a dependent variable and an independent variable.

The independent variable is that variable that you have to manipulate in order to receive a response. E.g, in the experiment described in the question, the amount of sunlight a sunflower plant receives is the independent variable.

The dependent variable is the number of seeds produced. It is the response obtained by carefully manipulating the amount of sunlight

Answers

Answer:

red blood cells and diffusion.

Explanation:

this process involves red blood cells and diffusion. Red Blood cells (RBCs) are a type of blood cell whose role is to transport oxygen from the lungs to the peripheral tissues of the body. Oxygen diffuses from the alveoli of the lungs in to the RBC's, where it binds to hemoglobin.

Diffusion is a very important process within the human body and is essential to the transport of molecules within a number of organs including the lungs, kidneys, stomach and eyes. The lungs process millions of tiny air sacs that are called alveoli, each of which are in close contact with capillaries.
