Answer: B
Explanation:
The reason its B because Ampere, unit of electric current in the International System of Units (SI), used by both scientists and technologists.
An electric current is a flow of electric charge in a circuit. More specifically, the electric current is the rate of charge flow past a given point in an electric circuit. The charge can be negatively charged electrons or positive charge carriers including protons, positive ions or holes.

A group of tourists were on an outing when they noticed that precipitation began to fall. The air temperature was 32 degree Fahrenheit. What type of precipitation did they most likely see?
Answer:
The correct answer is - rain.
Explanation:
At 32 degrees c or zero degrees Celsius, droplets of water in the atmosphere do not freeze as it is not the temperature at which water freezes but it is the temperature at which ice melts.
At this temperature the water changes its state, below 32 degrees Fahrenheit the water freezes but in the atmosphere, it not freezes necessarily and remains in the liquid state and called super-cooled liquid or water. Above this temperature, water in liquid state.
Thus, the precipitation is in the form of rain.

What are valence electrons? The number of neutrons in a nucleus. The number of protons in the nucleus. The atomic mass is the same as the number of valence electrons. The number of electron in the outer most shell of an atom.
Valence Electrons are The number of electrons in the outer most shell of an atom. These shells have a maximum amount before being filled by electrons, in which remaining electrons will fill the next remaining valence shell.

Given a balanced chemical equation it is always possible to determine
A)
the physical state of the products and reactants
B)
whether a reaction will or will not take place
C)
the relative number of moles taking part in the reaction
D)
the conditions necessary for the reaction to take place
Answer:
C) the relative number of moles taking part in the reaction
Explanation:
From a balanced chemical equation, it is always possible to determine the relative number of moles taking part in a chemical reaction.
The number of moles is the amount of the reacting specie that makes up a chemical reaction.
In balanced chemical equation, the number of moles of reactants and products must be the same. From this understanding, we can determine the amount of reactants and products needed for a chemical reaction to take place.If you start with 14.0 grams of diatomic nitrogen (N2) how many grams of diatomic hydrogen (H2) will react with it?

Susan is investigating physical changes. To do this, she places some ice into a large bowl and seals it with a lid. She leaves the bowl on the counter for several hours until all of the ice has melted. Using a balance, Susan determines that the mass of both the water and the ice are equal. Why is the mass of the ice and the water the same? (SC.8.P.9.1)
Answer:
No mass loss
Explanation:
The mass of ice and the water in the different state are equal because the same of quantity of matter is present in both state of matter of matter.
In essence, the mass of the physical change process is conserved. When mass is conserved, matter is neither created nor destroyed but can be changed from one form to the other. This is in compliance with the law of conservation of matter. So, no mass was lost in the physical change process and the mass will remain the same.5. The compound is called:

Which is the correct Lewis dot structure for BeH2 ?
The correct Lewis dot structure for [tex]BeH_2[/tex] is Be : H : H
What does the Lewis dot structure show?The Lewis dot structure shows the valence electrons as dots. The valence electrons of beryllium are shown as 2 dots on the left side of the atom.
The central atom, beryllium, has 2 valence electrons where each hydrogen atom has 1 valence electron. To form a stable molecule, beryllium shares its 2 valence electrons with the 2 hydrogen atoms, each of which shares its 1 valence electron with beryllium which gives each atom a full outer shell of electrons.

The chemical equation describing the burning of hydrogen gas is: 2H2 + O2 ---> 2H2O.
Why is this both a synthesis and a combustion reaction?
Answer:
"A combustion reaction is a reaction in which a substance reacts with oxygen gas, releasing energy in the form of light and heat. Combustion reactions must involve O2 as one reactant. The combustion of hydrogen gas produces water vapor." and "A synthesis reaction occurs when two or more reactants combine to form a single product. ... In a double replacement reaction, two compounds exchange elements. A combustion reaction occurs when a substance reacts quickly with oxygen. Combustion is commonly called burning"

Explain why the electron configuration of 2-3-1 represents an atom in an excited state?
Answer:
See explanation
Explanation:
If we look at the electron configuration closely, we will discover that the element must have had a ground state electron configuration of 2,4.
This is because, the innermost shell usually holds two electrons while the outer shells hold eight electrons each. The four electrons must be accommodated in the second shell in the ground state configuration of the compound.
However, when the atom is excited, one electron from this shell may move to the third shell to give the excited state configuration 2-3-1 as shown in the question.
You have discovered an element that is a poor conductor of electricity, has a low melting point, and is a gas at room temperature. How would you classify this element?
A.metal
B.metalloid
C.actinoid
D.nonmetal
How many molecules are equal to 3.25 moles of carbon dioxide?
Answer:
1.957 × 10²⁴ moleculesExplanation:
The number of carbon dioxide molecules can be found by using the formula
N = n × Lwhere n is the number of moles
N is the number of entities
L is the Avogadro's constant which is
6.02 × 10²³ entities
From the question we have
N = 3.25 × 6.02 × 10²³
We have the final answer as
