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
Answers
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

How is the behavior of food coloring in the cool and heated water different? What caused the differences in their behavior?
Please don't just give the sample response.
Answers
Answer:
The food coloring mixes much faster in the hot water than it mixes with the cold water. This is because in the hot water, water molecules have more energy and are moving faster than the molecules of cold water.

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).

Complete the sentences to identify the difference between a nonmetal atom and its anion.
In an anion, there are more *blank* than *blank*, giving the anion a *blank* charge.
In nonmetal atoms, the number of *blank* and *blank* are the same and there is a *blank* charge.
key bank:
- a positive
- no net
- electrons
- protons
- a negative
- neutrons
Answers
Answer:
more protons than neutrons and the number of electrons and blank are blank
Explanation:
The complete sentences that distinguish the difference between a nonmetal atom and its anion are as follows:
In an anion, there are more electrons than protons, giving the anion a negative charge. In nonmetal atoms, the number of protons and neutrons are the same and there is a negative charge. What are Non-metals?Non-metals may be defined as the type of chemical element that lacks the characteristics of a metal. They do not show any metallic attributes. But in the periodic table, they range from colorless gases to shiny and high melting point solids.
In the whole periodic table, elements are classified into three parts. They are metals, non-metals, and metalloids. Each classification has its own attributes and characteristic properties.
The non-metals significantly gain electrons due to their stronger nuclear charge and become negatively charged anions.
Therefore, the complete sentences that distinguish the difference between a nonmetal atom and its anion are appropriately described.

What geometric shape is the carbon dioxide molecule? The Lewis structure for CO2 contains two double bonds.
Answers
Explaination: The central atom of a carbon dioxide molecule is carbon. Carbon is tetravalent which just means it has 4 valence electrons. Because the valence shell isn’t full, the carbon atom can bond with other atoms creating a total of 4 bonds. This then allows the carbon to double bond with 2 oxygen atoms. Now, the atoms in the CO2 molecule Don’t share the electrons evenly because of atomic number or proton count. Because oxygen has an atomic number of 6, carbon has an atomic number of 4, and opposites attract (referring to the positivity of the nucleus and the negativity of the shared electrons), the oxygen atoms will have a slightly negative charge (-) and the oxygen will have a slightly positive charge (+ ). Therefore, the slightly negative oxygen atoms repel creating that linear shape.

Which metal reacts spontaneously with NiCl2(aq)?
A) Au(s)
B) Cu(s)
C) Sn(s)
D) Zn(s)
Answers
Answer:
THE answer IS B)cu(s)
Explanation:
HOPE ITS HELP
The metal reacts spontaneously with aqueous solution of NiCl₂ is Zinc as it is more reactive.
What is reactivity series?Electro chemical series is a reactivity series which tells about the reactivity of the metals present in any solution in the increasing order.
According to the reactivity series, Zinc is present at the upper position as compares to other three given metals and their reactivity will be represented as:
Zn > Ni > Sn > Cu > Au
So, zinc will replace the nickel atom from NiCl₂ solution.
Hence option (D) is correct.

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.

John rode 3150 m at an average speed of 350 m/min.If he had ridden at average of 375 m/min instead. How much sooner would it have taken? (In seconds)
Answers
Answer:
36
Explanation:
It would have taken 36 s for John to cover the distance.
Average speed is defined as the total distance travelled divided by the total time taken.
Average speed = Total distance / total timeTo obtain the answer to the question, we'll begin by calculating the time taken to cover the distance (3150 m) in each case.
Case 1:Average speed = 350 m/min
Total Distance = 3150 m
Time 1 =?Average speed = Total distance / total time
350 = 3150 / Time 1
Cross multiply
350 × Time 1 = 3150
Divide both side by 350
Time 1 = 3150 / 350
Time 1 = 9 mins
Multiply by 60 to express in seconds
Time 1 = 9 × 60
Time 1 = 540 sCase 2:Average speed = 375 m/min
Total Distance = 3150 m
Time 2 =?Average speed = Total distance / total time
375 = 3150 / Time 2
Cross multiply
375 × Time 2 = 3150
Divide both side by 375
Time 2 = 3150 / 375
Time 2 = 8.4 mins
Multiply by 60 to express in seconds
Time 2 = 8.4 × 60
Time 2 = 504 sFinally, we shall determine how much sooner it would have taken John to travel at 375 m/min. This can be obtained as follow:
Time 1 = 540 s
Time 2 = 504 s
Difference in Time =?Difference = Time 1 – Time 2
Difference in time = 540 – 504
Difference in time = 36 sTherefore, it would have taken John 36 s if he had travelled at an average speed of 375 m/min.

Answers
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.
because the positive and negative atoms always valence out.
