Which is the IUPAC name for NO?
nitric oxide
binitrogen oxide
dinitrogen dioxide
nitrogen monoxide
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.

What is force and motion
Answers
Answer:
In physics, a force is any interaction that, when unopposed, will change the motion of an object. A force can cause an object with mass to change its velocity (which includes beginning moving from a state of rest), i.e., to accelerate. Force can also be described intuitively as a push or a pull.

How many moles are in a sample of 2.39 x 10^23 atoms of sodium (Na)
Answers
Answer:
The answer is 0.4 molesExplanation:
To find the number of moles in a substance given it's number of entities we use the formula
[tex]n = \frac{N}{L} \\ [/tex]
where 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
[tex]n = \frac{2.39 \times {10}^{23} }{6.02 \times {10}^{23} } \\ = 0.39700996...[/tex]
We have the final answer as

32 N of Force. 37 N force. How strong is the net force and in which direction?
Answers
Explanation:
They are working against each other. That means you subtract.
32 - 37 = -5
You are moving 5 units to the left because 37 is negative which means it is moving left. The key word is left. In physics, you would get the same answer if you did it this way.
37 - 32 = 5
The 5 moves in the same direction as the 37

25 cm of liquid 'A' and 20 cm of liquid
'B' are mixed at 25°C and the volume of
solution was measured to be 44.8 cm3
then correct reaction is
(A) A Hmix = 0, solution shows
ideal
Answers
Answer:
The correct option is;
(B) [tex]\Delta H_{mix} < 0[/tex], solution shows negative deviation
Explanation:
The given parameters are;
The available volume of liquid A = 25 cm³
The available volume of liquid B = 20 cm³
The volume of the solution (mixture) = 44.8 cm³
Therefore, we have;
[tex]\Delta _{mix} V < 0[/tex]
Which is one of the prerequisite for the formation of negative deviation
When a non-ideal solution shows negative deviation according to Raoult's Law, we have;
[tex]\Delta _{mix} H < 0[/tex], we have more heat released due to new molecular interactions.

water rises to 508 ml. What is the mass of the metal object?
Answers
Answer:
The answer is 16 gExplanation:
The mass of a substance when given the density and volume can be found by using the formula
mass = Density × volumeFrom the question
density = 2 g/ml
volume = final volume of water - initial volume of water
volume = 508 - 500 = 8 mL

You are about to take a short trip. However, you will not be traveling by car or bus; instead you will be traveling up in a hot air balloon. You know that hot air balloons, like the ones pictured, are able to rise when the air contained in them is heated. Why does the balloon rise? What is happening at the molecular level to make the balloon rise?
Answers
Answer:
Hot air rises. Heated air molecules “spread out” or expand and bounce around, and the space becomes less dense than the surrounding space. Increasing the air temperature inside the balloon envelope makes it less dense than the air, thus making it “lighter than air”.

Balloon rise because Warm air ascends. Heat causes the molecules of the air to "spread out," or expand, and bounce off one another, making the area less dense than the surroundings.
What are molecules ?
A molecule is the smallest unit of a substance that keeps its content and properties. It is made up of two or more atoms that are joined together by chemical bonds.
Chemistry is built on molecules. The element symbol and a subscript indicating the number of atoms are used to identify molecules.

Answers
Answer:
B. A few positive particles bounced back because they were pushed away from the positive center.
Explanation:
The result of the experiment conducted by Rutherford shows that a few positive particles bounced back because they were pushed away from the positive center.
This is the central theme of Rutherford's experiment on a thin gold foil.
In 1911, Rutherford performed the gold foil experiment that gave the modeling of the atomic structure a great boost. He bombarded a thin gold foil with alpha particles. He discovered that most of the alpha particles passed through the foil while a few of them were deflected back. This led him to postulate that an atom has a small positively charged center where nearly all the mass is concentrated.Need help ASAP please

Scientists have changed the model of the atom as they have gathered new evidence. One of the atomic models is shown below. A purple center outlined in black with two concentric black circles around the center, the inner circle having 2 small green balls on it and the outer circle having 8 small green balls on it. What experimental evidence led scientists to change from the previous model to this one? A few of the positive particles aimed at a gold foil seemed to bounce back. The colors of light emitted from heated atoms had very specific energies. Experiments with water vapor showed that elements combine in specific proportions. Cathode rays were bent in the same way whenever a magnet was brought near them.
