You have an empty milk container, and you close the cap on the container. Do the particles of air that you trapped inside the container have mass? Explain how you know.
Answers
Answer:
Yes the air particles have mass
Explanation:
Air is mater: it has weight and occupies space. For it to have weight, it has to have a mass. The mass would however be determined by how much volume of air is trapped in the container, but nevertheless, the mass of the air can be obtained.
We also notice that if the container is "popped", the mass of air escapes through one way by the weight exerted on it.

Convert each of the following masses to the units requested.
a. 0.765g to kilograms
b. 1.34 g to milligrams
c. 34.2mg to grams
Answers
Answer:
a) 0.000765kg
b) 1340mg
c) 0.0342g
Explanation:
a) 1000g = 1kg
0.765g= 0.765/ 1000
= 0.000765g
b) 1g = 1000mg
1.34g = 1.34 × 1000
= 1340mg
c) 1000mg = 1g
34.2mg = 34.2/1000
= 0.0342g

A student combines two clear liquid chemicals together in a beaker. When the two chemicals are combined, bubbles are formed, the solution turns blue, and you can see flakes of something forming on the bottom of the beaker. Is this a physical or chemical change? Why?
Answers
Answer:
chemical change
Explanation:
A physical change is one that makes changes to the physical properties of matter. In many cases, the difference is usually reversible. Examples include boiling, melting, freezing, the magnetization of metals, etc.
A chemical change is one in which a new kind of matter is formed. It is usually accompanied by energy changes, i.e., the evolution or absorption of energy in the form of heat or light. This process is not easily reversible. Examples include; combustion, rusting of iron, precipitation, the souring of milk, etc.
From the question given, the combination of two clear liquid in a beaker which results to formation of bubbles and changes in coloration of the solution is a chemical change.

Answers
Answer: Its B/Climate
Im pretty sure if its wrong srry!
Hope this helped!
Explanation:
Apart from different ways to classify soils. The one factor that scientists use to classify orders of soil is climate. Hence, Option (B) is correct
What is Climate ?Climate is the long-term pattern of weather in a particular area.
Weather can change from hour-to-hour, day-to-day, month-to-month or even year-to-year.
A region's weather patterns, usually tracked for at least 30 years, are considered its climate.
Other factors people uses in classifying orders of soil are;
ClimatePlant typeSoil compositionSoil orders are known as the single dominant attributes affecting soils in any location.
They can be the prevalent vegetation such as Alfisols and Mollisols or the type of parent material such as Andisols and Vertisols or the climate variables such as lack of precipitation etc.

Answers
The IUPAC name for NO is nitric oxide. The correct option is A.
What is IUPAC naming?The International Union of Pure and Applied Chemistry (IUPAC) is a global organization that represents chemistry as well as related sciences and technologies.
The chemical compound's identity is represented by its common and IUPAC names, which differ from one another. Every chemical compound has multiple names.
Complete the following step-by-step response: The IUPAC nomenclature is a standardized name given to organic compounds in accordance with official naming rules.
Nitric oxide, also known as NO, is a colorless gas. It is one of the most important nitrogen oxides.
Nitric oxide is a free radical, which means it has an unpaired electron, which is sometimes represented in its chemical formula by a dot.
Thus, the correct option is A.

How are electrically neutral atoms different than they form
Answers
An atom is said to be electrically neutral if it has an equal amount of protons and electrons. On the other hand, an atom is electrically charged if its protons and electrons are not distributed evenly.
What are neutral atoms?Neutral atoms are defined as when an atom has an equal amount of protons and electrons, it also has an equal number of electric charges, both positive and negative. As a result, every element in the periodic table has a neutral atomic structure.
Normal atoms have an equal amount of positive and negative particles and a neutral charge. Accordingly, an atom with a neutral charge is one in which the atomic number is matched by the number of electrons.
Thus, an atom is said to be electrically neutral if it has an equal amount of protons and electrons. On the other hand, an atom is electrically charged if its protons and electrons are not distributed evenly.

Explanation:
It is given that, the frequency of Ultraviolet radiation is [tex]6.8\times 10^{15}\ Hz[/tex]
We need to find the energy of the photon. The formula for the energy of a photon is given by :
[tex]E=hf\\\\\text{Where h is Planck's constant}\\\\E=6.63\times 10^{-34}\times 6.8\times 10^{15}\\\\E=4.5\times 10^{-18}\ J[/tex]
So, the energy of the photon is [tex]4.5\times 10^{-18}\ J[/tex].
