Oxygen has 8 positively-charged protons. What is the number of negatively-charged electrons in an atom of Oxygen?
Answer:
Answer 9: Oxygen is atomic number 8 on the periodic table, which means it has 8 protons!
Explanation:
Oxygen's 8 electrons are negatively charged, and they orbit the atomic nucleus and balance the positive charge of the 8 protons. The positive charge of 1 proton exactly cancels the negative charge of 1 electron.

Why does the border between light and dark on the Moon change location?
We only view a portion of the lighted part of the Moon because of how the Moon rotates around the Earth.
What is solar system?Solar system is defined as the Sun's orbiting objects are confined by gravity to one system. The Solar System is the only system in which a habitable planet has been observed, the only star we can observe up close, and the only planets we can explore with spacecraft. Understanding the creation and evolution of planets as well as the conditions required for life requires extensive investigation into the solar system.
The terminator is the line on the moon that divides day from night. The moon's surface is in a twilight state along the terminator line, which is where the twilight zone is frequently referred to as. The sun is either rising or setting on the moon along this line.
Thus, we only view a portion of the lighted part of the Moon because of how the Moon rotates around the Earth.

What happens to the reaction rate as the reactants get used up in a reaction?
O
A. The rate of the reaction is not affected by the concentration of
reactants.
B. The rate of the reaction increases steadily as products are formed.
O
O
O
C. The rate of the reaction begins to decrease as reactants are used
up
O
D. The rate of the reaction stays constant until the reactants are
gone.
The rate of the reaction depicts the speed at which the reaction occurs to produce the products. As the reactants get used up the reaction rate starts decreasing. Thus, option C is correct.
What are the factors affecting reaction rate?
The reaction rate of the chemical reaction gets affected by numerous factors that include temperature, the concentration of the reactants, catalyst, surface area, and physical state of the reactant.
The concentration of the reactant has a direct effect on the reaction rate as they are the deciding factor of the product formation. At the beginning of the reaction, the speed is fast compared to the end.
As the reactants start getting used up the reaction rate slows down as the molecules are not able to collide faster with other molecules to form the product.
Therefore, in option C. the reaction rate decreases with a decrease in concentration.

Making an apple pie is different from making lead iodide as lead iodide is a chemical compound and requires chemical process which is poisonous to eat while an apple pie is an eatable which is safe to eat.
What is a compound?Compound is defined as a chemical substance made up of identical molecules containing atoms from more than one type of chemical element.
Molecule consisting atoms of only one element is not called compound.It is transformed into new substances during chemical reactions. There are four major types of compounds depending on chemical bonding present in them.They are:
1)Molecular compounds where in atoms are joined by covalent bonds.
2) ionic compounds where atoms are joined by ionic bond.
3)Inter-metallic compounds where atoms are held by metallic bonds
4) co-ordination complexes where atoms are held by co-ordinate bonds.
They have a unique chemical structure held together by chemical bonds Compounds have different properties as those of elements because when a compound is formed the properties of the substance are totally altered.

Which unit conversion allows you to convert 21.0 gallons into milliliters?
Some English and English-metric unit relationships: 1 liter = 1.057 quarts, 1 gallon = 4 quarts
Answer:
Explanation:
we are given
there are in 0.073 gallons
we can see that there are two non-zero places after decimals
so, there are two siginificant figures
step-1: Change gallons to quarts
we know that
1 gallon = 4 quarts
so, we can write as
step-2: Change into liter
we know that
1 liter = 1.057 quarts
or
step-3: Change into millilitre
we know that
Since, it is asking for only two significant figures
so, we can also write as

Answer:
The water cycle evaroprate from the sufrace of the water and rises into the atmosphere.
The water cycle is how water evaporates from the surface of the earth, rises into the atmosphere, cools and condenses into rain or snow in clouds, and falls again to the surface as precipitation. The cycle of water are in and out of the atmosphere is a significant aspect of the weather patterns on Earth.
Explanation:
Step by Step
Step 1 Evaporation: This is when warmth from the sun causes water from oceans, lakes, streams, ice and soils to rise into the air and turn into water vapor (gas).
Step 2 Condensation
Step 3 Precipitation

Chiara knows that weight is affected by gravitational pull. She is putting together a poster to display in her classroom.
Since the moon's gravity is less than Earth's, all objects, including mammals, have different weights on the moon than on Earth. Use the table below to calculate how much a dog weighs on the moon.
Answer: A
Explanation: 150 lb * 1/6 = 25 lb
Chiara knows that weight is affected by gravitational pull. The weight of the dog on the moon is 25 lb. The correct option is A.
What is gravitational pull?Gravitational pull is the force of gravitation that pulls all the objects towards themselves. The force of gravitation is different on different planets, and on the moon, the gravitational pull of the moon is lesser than the earth.
The weight of the dog on the earth is 150 lb
The weight of any object on the moon is 1/6th of the weight of any object on the earth.
So to calculate the weight of the object on the moon, we should multiply the given weight of the dog on the moon by 1/6 to get the result.
150 lb x 1/6 = 25 lb
Thus, the weight of the dog on the moon is 25 lb. The correct option is A.
