if the electron affinity for an element is a negative number, does it mean that the anion of the element is more stable than the neutral atom?
Answer: No
Explanation: It means that an electron in an atom or ion is lower in energy than a free electron.
No, the anion of the element is more stable than the neutral atom but an electron in an atom or ion is lower in energy than a free electron.
What is kinetic energy?Kinetic energy is defined as the energy of the object that occurs due to the motion of the object. The total work needed by the body to starts accelerating it by the help of given mass which is supplied from the rest position and its mentioned velocity.
The energy body gets due to the process of acceleration by this the body will able to main the kinetic energy of the body without changing the speed of the body. The energy which has been stored in the body or any object by the help of the particular position or the proper arrangement of the parts is known as potential energy.
There will be no effect of the outside environment on the potential energy that present inside the body. The kinetic energy decrease or increase with change into the velocity.
Therefore, No, the anion of the element is more stable than the neutral atom but an electron in an atom or ion is lower in energy than a free electron.

Answer:
Metal -c
Explanation:
this ionic compound is named incorrectly.
1. find and describe the mistake
2. correctly name the compound
CaCl² - Calcium Chlorine
CuS - Copper Sulfide
Li³P - Trilithium Phosphide
CuBr - Copper(II) Bromide
NaOH - Sodium Hydrogen Oxide
1. Ionic compounds are named using the cation and the anions in the compounds respectively.
The name of the cation remains thesame as it's element while the anions name changes by adding another suffix to the elements name.
Sometimes, the number of positive charge of a cation is added in front of it's name before adding the anion's name.
2. Correct names of the compounds above
CaCl² - Calcium chloride
CuS - Copper Sulphate
Li³P - Lithium Phosphide
CuBr - Copper (1) Bromine
NaOH - Sodium Hydroxide

What is ideal gas equation?Ideal gas equation of gases gives idea about the behavior of gases at different conditions and it will be represented as:
PV = nRT, where
P = pressure
V = volume
n = moles
R = universal gas constant
T = temperature
After rearranging the equation, we get
P/RT = n/V
Quantities which are present on the left side all are constant and the value on the right side describes the density of the water.
Hence they must have same density.

What happens inside a closed car on a hot day?
A. The pressure inside the car increases.
B. The molecules of gas slow down.
C. The number of molecules increases.
D. The volume inside the car increases.
Answer:
Explanation:
What happens inside a closed car on a hot day?
A. The pressure inside the car increases.
B. The molecules of gas slow down.
C. The number of molecules increases.
D. The volume inside the car increases.
The sunlight in the closed car increases the temperature, which makes the air molecules move faster, hitting the interior walls and windows more rapidly and thus increasing the pressure.
The answer is A.
That is why you never leave car windows rolled up on a hot day with a young child or pet inside. They can get sick and possibly die from overheating.

The outermost shell of an atom is called Valence shell.why?
Answer:
The number of electrons to be filled in each shell depends on Aufbau's principle and Hund's rule. Valency tells us only the total number of electrons present in the outermost shell of the atom and so it is different from the atomic number. Therefore, the outermost shell of an atom is known as valence shell.

We know that organisms pass traits onto their offspring through reproduction. So how is it
possible that a new trait could ever appear in a population? Wouldn't a trait have to already
exist in the population?
Answer:
There are recessive traits and dominant traits
Explanation:
recessive traits are always hidden
dominant traits are the ones that are present in an organism
some recessive traits can be passed on to offsprings to become dominant
and some dominant traits can be passed on to become recessive traits

A student needs to make 0.855 L of a sodium bromide solution for an experiment. The concentration of the required solution is 0.350 M. How many grams of sodium bromide will he need to use?
Answer:
Explanation:
Molarity = moles/liters of solution
moles = molarity x Liters of solution
= 0.350 m/L x 0.855 L
= 0.299 mol
mass = moles x molar mass
= 0.299 mol x 102.89 g/ms
= 30.78 grams

All living organisms do cellular respiration and give off carbon dioxide. TRUE OR FALSE
Answer:
false
Explanation:
All living things use cellular respiration to turn organic molecules into energy. Cellular respiration is the chemical process of breaking down food molecules in order to create energy in the form of adenosine triphosphate (ATP). ... This is called aerobic respiration.
Cellular respiration takes place in all living organism despite the level of organism and produces carbon dioxide and water.
What is cellular respiration?Cellular respiration is the process of breaking food or glucose by the action of biological catalysts to form carbon dioxide and water. This process goes through several stages including some electron transport chains
There are both aerobic and anaerobic respiration. Aerobic respiration takes place in the presence of oxygen whereas anaerobic respiration needs no oxygen.
Every living organism consume food and digest and from the food the cell makes energy by cellular respiration. Hence, the fact that all living organism do cellular respiration is true.
