How do you take sharpie of the table hellp i go sharpie on the table when i was doing art

Please I need help with this question due for the next 3 hours will mark brainliest to fast first and best and will get 50 marks

1) Chemistry

(a)they have intermolecular forces between molecules

(b) collisions aren't always elastic (also due to intermolecular forces) (c) gas molecules have volume.

2) CHEMISTRY

Charles's law (also known as the law of volumes) is an experimental gas law that describes how gases tend to expand when heated. A modern statement of Charles's law is: When the pressure on a sample of a dry gas is held constant, the Kelvin temperature and the volume will be in direct proportion.

3) AGRIC

bush burning creates soil that is lacking in nitrogen. Micronutrients, normally present in soil with decomposing vegetable matter, are lacking in soils after a fire. The combustion process of bush burning also increases soil's pH.

4) Data processing

INTERNET of THING will be the perfect match

5) ELECTRICITY GENERATION

Electricity is most often generated at a power plant by electromechanical generators, primarily driven by heat engines fueled by combustion or nuclear fission but also by other means such as the kinetic energy of flowing water and wind. Other energy sources include solar photovoltaics and geothermal power.

6) BIOLOGY

Pollution is the introduction of contaminants into the natural environment that cause adverse change. Pollution can take the form of chemical substances or energy, such as noise, heat or light. Pollutants, the components of pollution, can be either foreign substances/energies or naturally occurring contaminants.

Pollutants are substances that caused the pollution

CAUSES OF POLLUTION AND EFFECT

global warming, acid rains, respiratory and heart problems, and eutrophication. ... Industrial activity, waste disposal, agricultural activities, acid rain, and accidental oil spill

BabaBlast [244]

This apparent contradiction between the chlorine ion and the sodium ion is; due to electrostatic attraction between the nucleus and the electrons.

As we know, there's a periodic trend for atomic radii in the periodic table; the trend is as follows;

<em>Atomic radius increases down a group and reduces across the period.</em>

Elements get larger down the group and this explains the trend down a group.

However, atomic radius decreases across a period because the more Valence electrons there are in an element, the more the electrostatic attraction between the positively charged nucleus and the negatively charged electrons.

Consequently, when Chlorine forms an ion by gaining an electron, the electrostatic attraction between its nucleus and electrons increases and the the atomic radius decreases.

On the other hand, when sodium forms an ion by losing an electron, the electrostatic attraction between its nucleus and electrons decreases and the the atomic radius increases.
