Explanation: When an atom gains/loses an electron, the atom becomes charged, and is called an ion. Gaining an electron results in a negative charge, so the atom is an anion.

A chemist who frequently carries out a complex experiment is
likely to have high:
a. Precision, but low accuracy
b. Precision
c.Accuracy, but low precision
d.Accuracy
Answer:
c.
Explanation:
This is because the chemist will get the average of the experiment from multiple attempts but not precision because the experiment is complex rather than simple.
The chemist will most likely have high accuracy, but low precision. A
chemist who has been performing experiments frequently will be accurate
when taking the required measurements for the experiment due to the
frequency.
Precision however won't be affected because precision deals with how
close his results from the experiment are. The complexity of the
experiment and the different variables used makes him likely to have low
precision.

Based on their definitions, electron affinity could be considered the opposite of
Based on their definitions, electron affinity could be considered the opposite of electron affinity. This is the force required to remove an electron from an atom while it is gaseous, or the propensity of an atom to lose electrons.
What is meant by electron?The electron is a subatomic particle with a negative one elementary charge electric charge. Due to their lack of components or substructure, electrons, which are part of the lepton particle family's first generation, are typically regarded to be elementary particles.
An electron is a negatively charged subatomic particle that can exist either free or bound to an atom (not bound). Along with protons and neutrons, electrons are one of the three primary types of particles that make up an atom. Together, protons, neutrons, and electrons make up the atom's nucleus.
This is the force required to remove an electron from an atom while it is gaseous, or the propensity of an atom to lose electrons. Conceptually, this is the polar opposite of electron affinity.

the maximum internal receiving temperature for fresh poultry is:
It should be noted that the maximum internal receiving temperature for fresh poultry is 41°F.
Temperature simply refers to the measure of hotness or coldness which is expressed in several scales. It's the manifestation of thermal energy in a matter.
It should be noted that the key to limiting the bacterial growth of food is to control the temperature. The maximum acceptable receiving temperature for fresh poultry is 5°C (41°F).

Which property has a trend similar to that of electronegativity?
A. First ionization energy
B. Atomic radius
C. Ionic radius
D. Atomic mass
Answer:
a
Explanation:
There are various kind of elements that are present in periodic table. Some elements are harmful, some are radioactive, some are noble gases. Therefore, the correct option is option A.
What is periodic table?Periodic table is a table in which we find elements with properties like metals, non metals, metalloids and radioactive element arranges in increasing atomic number.
Periodic table help a scientist to know what are the different types of elements are present in periodic table so that they can discover the new elements that are not being discovered yet.
Along period, electronegativity increases. along group electronegativity decreases. The same trend is followed by first ionization energy in periodic table.

A 12.0 L helium balloon is inflated in an air-conditioned store at 21.0C. Assuming that the pressure remains constant, how large is the balloon when it is taken outside on a hot day at 40.0C?
The ballon will be 22.86L large when it is taken outside on a hot day at 40⁰C
According to pressure law, the volume of a given mass of gas is directly proportional to the temperature. This is expressed as:
V = kT
k = V1/T1 = V2/T2
Given the following parameters
V1 = 12.0L
T1 = 21⁰C
T2 = 40.0⁰C
Required
Final volume
Substitute the given parameters into the formula
12/21 = V₂/40
21V₂ = 12 * 40
21V₂ = 480
V₂ = 480/21
V₂ = 22.86L
Hence the ballon will be 22.86L large when it is taken outside on a hot day at 40⁰C.

2. What is the difference between a Chemical Process and a Physical Process?
3. How many electrons fit in each shell around an atom?
Answer:
a) Diamond can indeed be set on fire since it is made of carbon. ... Although diamond requires a higher temperature to burn, it does indeed burn via normal carbon combustion. You can even burn diamond in a regular flame if you are patient and conditions are right.
b) In a physical change the appearance or form of the matter changes but the kind of matter in the substance does not. However in a chemical change, the kind of matter changes and at least one new substance with new properties is formed. The distinction between physical and chemical change is not clear cut.
c) Each shell can contain only a fixed number of electrons: The first shell can hold up to two electrons, the second shell can hold up to eight (2 + 6) electrons, the third shell can hold up to 18 (2 + 6 + 10) and so on. The general formula is that the nth shell can in principle hold up to 2(n2) electrons.

Mercury, which has 1/3 the gravity of
Earth?
A. more than on the Earth
B. less than on the Earth
C. the same as on earth
Answer:
The same as on earth
Explanation:
mass is the amount of matter in an object and the mass of an object is always the same at any point in time
gravity will only have effect on the weight and not the mass.
so assuming the question was talking about the weight, then we can say the weight will be lesser on Mercury

B. 00035416 g/cm^3
C. 354.16 g/cm^3
D. 3541.6 g/cm
Answer:
The answer is D.
Explanation:
Volume (V) = l x w x h
V = 4 x 5 x 1.2
V = 20 x 1.2
V = 24
Density = Mass/Volume or D = M/V
D = 85,000/24
D = 3541.66666666
