Circle the two terms in each group that are related. Explain how the terms are related.
16. Celsius degree, mass, Kelvin
17. balance, second, mass
18. kilogram, liter, cubic centimeter
19. time, second, distance
20. decimeter, kilometer, Kelvin
Answer:
16) Celsius degree and Kelvin are related since they are measuring unit of temperature.
(17) Balance and Mass are related since mass can be measured with balance.
18) Liter and cubic centimeters are related since they are used to measure capacity or volume of liquid.
19) time and second are related since time is measured in second
20) decimeter and kilometer are related since they are measuring unit of distance or displacement.
Explanation:
The two terms in each group that are related are Celsius and Kelvin, balance and mass, liter and cubic centimeter, time and second, and decimeters and kilometers.
What are Celsius and Kelvin?Celsius and Kelvin are the units and they are related to each other because both of them can be used to determine or to define the temperature of the environment for anything which is needed to be measured.
The balance and mass are related to the balancing of mass and kilogram with centimeter cubic are related for density and time and second is related to each other last decimeters and kilometers unit of lengths.
Therefore, two terms in each group that are related are Celsius and Kelvin, balance and mass, liter and cubic centimeter, time and second, and decimeters and kilometers.

why does the s orbital fill before the p orbital
Answer:
The s orbital is lower in energy than the p orbital
Explanation:
S-orbital electrons are simultaneously closer to the nucleus (more stable) and farther from the nucleus (less stable) compared to the corresponding p-orbitals. This makes them favorable to occupy when no p-electrons are present, but less favorable to occupy when p-electrons are present, which is why they are filled first but ionize first.

Explanation: because when it’s stretched it has the most potential kinetic energy
Assertion : When the added electron goes to smaller n=3 quantum level, the electron-
electron repulsion is much less.
Reason: The added electron occupies a smaller region of space .
It is due to low volume of electron that causes large distance between two electrons.
When the added electron goes to smaller quantum level, the repulsive force between two electrons is less because the electron which is added occupies small space due to less volume so there is a large distance between two electrons that leads to less force of repulsion.
If the electron has more volume so it occupies more space and there will more repulsive force between two electrons so that's why we can say that the smaller volume of electron is the reason of less repulsive force.

Which statement about metals and nonmetals is correct? (1 point)
O Metals and nonmetals can both be found in any column of the periodic table.
O Most metals are a solid under normal conditions, and most nonmetals are a liquid.
O Metals tend to be poor conductors of electricity, while nonmetals are strong conductors of electricity.
O Metals can be hammered into thin sheets, and nonmetals are brittle
Answer:
The answer is the 4th one
The statement about metals and nonmetals that is correct is: "The Metals can be hammered into thin sheets, and nonmetals are brittle."
Metals are found mostly towards the left hand side of the periodic table. Non-metal character increases as you move towards the right hand side of the table.
One common property of metals is that they are malleable; this means that they can be hammered into sheets while a common property of nonmetals is that most of them are brittle.

Define measurement. why is it important in our life?
Answer:
Measurements are so often taken for granted we sometimes do not appreciate the grand importance measurements play in our lives. On a baseline level, measurements fall into the categories of weight, area, volume, length and even temperature. While we look at these various categories as stoic forms of mathematical measurements a closer examination of things we do in everyday life reveals their clear importance.
Explanation:
Measurements provide structure and remove the chaos that would result without any congruent method of understanding weight, mass, temperature, etc.
Answer:
The comparison of unknown physical quantity with the known standard quantity of the same kind is called measurement.
Measurements play an important role in daily life because they are useful to do basic tasks, such as take a child's temperature with a thermometer, make time estimations, measure out medicine and find weights, areas and volumes of different materials or substances.
Hope it helps you.Find the density of mercury if 205 mL has a mass of 2790 g round your answer to the nearest 0.1 g
Answer:
13.6g/L
Explanation:
The formula for density is D=m/V
D = Density in grams per liter (g/L)
m = Mass of sample in grams
V = volume of sample in liters
Convert 205mL to Liters as follows:
205mL (1L/1000mL) =0.205L
then simply plug into the equation for density:
2790g/0.205L = D= 13.6g/L

How does water vapor in the air change state below the freezing point
Answer:
Water vapor molecules in the air near the can cooled when energy from the air transferred to the cold can. These water molecules slowed down, condensed to liquid water, and then froze to become ice. Your can might have some water and some ice on the outside of it.

If you were converting from Milli- to Centi- units, how many decimal places would you move?
Answer:
1 decimal place
Explanation:
centi- is 10 times larger than milli- (centi- = 0.01 milli- = 0.001)
1 mili is equal to the 0.01 centi. Since all metric units differ by powers of ten, changing between them just necessitates moving the decimal point to the left or right.
What is difference between millimeter and centimeter ?The actual ratio is 10 millimeters to 1 centimeter. Now, it is clear that centimeters are bigger than millimeters.
There is no change in volume, these measurements are the same. The main distinction is that fluid quantities are measured in milliliters, but solid quantities are measured in cubic centimeters. 1 cc is 1 mL no matter what is being measured.
The units used to measure length are centimeters and millimeters, respectively. 1 cm is equivalent to 10 mm, and 1 millimeter is equal to 0.1 centimeter.
Thus, for converting from Milli- to Centi- units 10 digit place would be move.

A stable sodium atom has 11 electrons. The sodium isotope [tex]Na_{24}[/tex] has:
A.) How many protons?
B.) How many neutrons?
C.) An atomic number of what?
Answer:
Isotopes have same atomic numbers, no. of protons and no. of electrons. Only their no. of neutrons and atomic mass are changed.
Na - 24:
Atomic Mass = 24
Atomic No. = 11
Hence,
No. of protons in Na-24 = 11
No. of neutrons = Atomic Mass - Atomic Number
No. of neutrons = 24 - 11
No. of neutrons = 13
Atomic Number = 11
