Generally how does the first ionization energy vary as the atomic number increases going across a period
Vlad1618 [11]

Across a period I.E increases progressively from left to right

Explanation:

The trend of the first ionization energy is such that across a period I.E increases from left to right due to the decreasing  atomic radii caused by the increasing nuclear charge. This not compensated for by successive electronic shells.

  • Ionization energy is a measure of the readiness of an atom to lose an electron.
  • The lower the value, the easier it is for an atom to lose an electron.
  • Elements in group I tend to lose their electrons more readily whereas the halogens hold most tightly to them.
  • The first ionization energy is the energy needed to remove the most loosely bonded electron of an atom in the gaseous phase.

List the 3 ways carbon can enter the ocean?
prohojiy [21]

Carbon dioxide from the atmosphere dissolves in the surface waters of the ocean. Some of the carbon dioxide stays as dissolved gas, but much of it gets turned into other things. Photosynthesis by tiny marine plants (phytoplankton) in the sunlit surface waters turns the carbon into organic matte

The osmotic pressure of a solution increases as
s344n2d4d5 [400]
The osmotic pressure of a solution is a colligative property, which means that it depends on the number of particles of solute in the solution.

Formula: Osmotic pressure = MRT, where M is the molarity of the solution, R is the universal constant of ideal gases and T is the absolute temperature of the solution.

So, the answer is the option .: the osmotic pressure of a solution increases as the number of particles of solute in the solution increases.

How can you separate a mixture of dry materials
Kruka [31]
Any substance that is not a mixture is a pure substance. When colored watercolors are applied to paper, sometimes the colors in the ink separate. This technique is called chromatography

Calculate the atomic mass of Carbon if the two common isotopes of carbon have masses of
Mars2501 [29]

Answer:

Average atomic mass of carbon = 12.01 amu.

Explanation:

Given data:

Abundance of C¹² = 98.89%

Abundance of C¹³ = 1.11%

Atomic mass of C¹² = 12.000 amu

Atomic mass of C¹³ = 13.003 amu

Average atomic mass = ?

Solution:

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

Average atomic mass of carbon = (12.000×98.89)+(13.003×1.11) /100

Average atomic mass of carbon=  1186.68 + 14.43333 / 100

Average atomic mass of carbon = 1201.11333 / 100

Average atomic mass of carbon = 12.01 amu.
