Answer:

The common ion will be di-positive ion.

Explanation:

The ionization energy is defined as the amount of energy needed for removal of most loosely bound electron from an isolated atom in gaseous state.

The low ionization energy shows that the atom is able to give electron easily as after losing electron it may attain noble gas configuration or half filled stability.

Here the first and second ionization energy, both are low suggesting that the element is ready to give two electrons easily to form a di-positive ion however the third ionization energy is high which shows that it will not form tri-positive ion commonly.

Which statements describe the six elements found in all living things? Check all that apply.

vovangra [49]

Answer:

Carbon is the basis of all living things

Nitrogen is found in certain foods

Oxygen and hydrogen combine with each other to form water

Carbon, oxygen, hydrogen, nitrogen, phosphorus and sulfur are found in organic compounds

Explanation:

We are all made up of mainly three elements, Carbon, Hydrogen, and Oxygen. These three elements are found in every living organism on our planet, and along with a few trace elements, they make up all the nutrients we take in and use to build our bodies and survive.

Nitrogen is primarily found in meats, and this is because nitrogen is a key element in amino acids (which are used to build proteins), however we cannot directly assimilate nitrogen from the air, so we have to assimilate it through amino acids already synthesized in plants, or in proteins found in meat.

The chemical formula for water is H₂O. Seeing the chemical formula, it is obvious that hydrogen and oxygen are the only elements in the water molecule.

In our bodies, we use phosphorus to form our skeleton and help maintain it, sulfur and nitrogen can be found in some amino acids, and carbon, hydrogen and oxygen can be found in carbohydrates, lipids and proteins.

Calculate the frequency of light having a wavelength of 425nm. remember that 1nm=1×10−9m

Gnom [1K]

The frequency of light having a wavelength of 425nm will be 70588 × $10^{14} Hz$ .

The count of times an event takes place per unit of time is known as its frequency. The word frequency would be most frequently used to describe waves in physics including chemistry, including light, sound, including radio waves. The frequency refers to the number of times during one second that a point on a wave crosses a fixed reference point.

A waveform signal that is carried in space or down a wire has a wavelength, which is the separation between two identical places in the consecutive cycles.

Given data:

wavelength = 425nm = $425 * 10^{-9} m$

Frequency can be calculated by using the formula;

Frequency = speed of light / wavelength

Frequency = 3 × $10^{8} m/s$ / 425 × $10^{-9} m$ = 7,0588 × $10^{14} Hz$ .

Therefore, the frequency of light having a wavelength of 425nm will be 70588 × $10^{14} Hz$ .

What is the final pressure (expressed in atm) of a 3.05 L system initially at 724 mm Hg and 298 K, that is compressed to a final

maksim [4K]

Hey there!:

V1 = 3.05 L

V2 = 3.00 L

P1 = 724 mmHg

P2 = to be calculated

T1 = 298 K

T2 = 273 K

Therefore:

P1*V1 / T1 = P2*V2 / T2

P2 = ( P1*V1 / T1 ) * T2 / V2

P2 = 724 * 3.05 * 273 / 298 * 3.00

P2 = 602838.6 / 894

P2 = 674.31 mmHg

1 atm ----------- 760 mmHg

atm ------------- 674.31 mHg

= 674.31 * 1 / 760

= 0.887 atm

Hope this helps!
