Which of the following is true about the picture above? What would it be?
Answers
Answer:
Container A is a solution and Container B is a colloid.
Explanation:
Container A is a solution as the tyndall efffect is not present. You cannot see the light bean through the glass.
Container B is a suspension or a colloid as you can see the beam through the glass.
The first option proposes Container A is a colloid...this is not correct
The third option is not true as the tyndall effect is only displayed in container B
The fourth option is not correct the tyndall effect is not present in container A meaning it would not be a suspension or a colloid and you can see the tyndall effect in container B indicating its not a solution

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.

These models show the electron structures of two different nonmetal elements. Element 1 at left has a purple circle at center with 2 concentric black lines around it. The first line has 2 small green balls on it. The second line has 8 small green balls on it. Element 2 at right has a purple center with 5 concentric circles around it, with the first circle innermost. The first circle has 2 small green balls on it, and the second circle has 8 small green balls on it. The third circle has 18 small green balls on it, and the fourth circle has 18 small green balls on it. The fifth circle has 6 small green balls on it. Which element is likely more reactive, and why?
Answers
Answer:
Element 2
Explanation:
If we look at the model stated for element 1, it is clear that element 1 must be a noble gas. It has eight electrons in its outermost shell this implies that it has already attained a complete octet of electrons and is reluctant towards chemical reaction.
The second element belongs to group 16 since it has six electrons on its outermost shell. It is certainly more reactive than element 1 which is a noble gas.
Answer: D
Element 2 is more reactive because it does not have a full valence shell, so it will attract electrons.

What is the mass of an object with a density of 5.7 g/cm^3 and a volume of 48
cm^3? *
Answers
Answer:
273.6 g
Explanation:
mass =(density)(volume)
mass=(5.7g/cm^3 )(48 cm^3)
cancel out your cm^3 and your are left with grams
multiply (5.7g)(48)=273.6 g
The mass of an object with a density of 5.7 g/cm³ and a volume of 48 cm³ is 273.6 grams.
What is density?Density is defined as the degree to which a material is packed together.
It is also defined as a mass per unit volume of the substance.
Its SI unit is kilogram per cubic meter or gram per meter.
Density can be expressed as
Density = mass / volume
Mass = density x volume
As given, Density = 5.7 g/cm³
Volume = 48 cm³
So, Mass = 5.7 g/cm³ x 48 cm³
= 273.6 grams
Thus, the mass of an object with a density of 5.7 g/cm³ and a volume of 48 cm³ is 273.6 grams.

The MSDS for chloroform indicates that it is a clear liquid that has a pleasant smell and substantial vapor pressure. People should avoid inhaling its vapors, and it is sensitive to light. Malik needs 10 mls of chloroform for an experiment. According to this information, how should he safely pour the chloroform?
A.He should locate the chloroform stored in a transparent container in chemical storage and pour directly into his beaker from that location.
B.He should locate the chloroform stored in a transparent container in chemical storage and should take it to the fume hood to pour.
C.He should locate the chloroform stored in a dark container in chemical storage and should take it to the fume hood to pour.
D.He should locate the chloroform stored in a dark container in chemical storage and pour directly into his beaker from that location.
Answers
Answer:C.He should locate the chloroform stored in a dark container in chemical storage and should take it to the fume hood to pour.
Explanation:
The statement of the question clearly states that chloroform is sensitive to light and it's vapour is toxic.
If a substance is sensitive to light, then it must be stored in a dark bottle. This is because. If a substance that is sensitive to light is stored in a transparent container, it may be decomposed by light.
Being a substance whose fumes are toxic, Malik should pour the liquid in a fumes hood so that he does not inhale the fumes.

C.the pas particles are moving the slowest
D.the spacing of the particles is different, but all have the same average kinetic energy

Answers
Answer:
A
Explanation:
Solid particles only vibrate, so they have very little kinetic energy.
For B, the size of the particles stay the same, just phase/state changes, so not B.
For C, gas particles move the fastest compared to liquid and solid given the same environment.
For D, they don't have the same kinetic energy because solid particles barely move while gas particles keep moving.

Answer:
A) In aldehydes, the carbon is always joined to at least one hydrogen atom.
Explanation:
Aldehydes and Ketones are organic compounds.
The main difference between them is that aldehydes have the carbon atom attached to at least one hydrogen atom.
In ketones, the carbon is attached to another carbon.
The IUPAC names of alkanals usually end with -eFor alkanones usually end with -oneTo reiterate, the striking difference between the two families is that in alkanals, a hydrogen atom is directly attached to the carbonyl group while in alkanones, no hydrogen atoms is attached to the carbonyl group but two bulky alkyl groups.

C. 20 J to 25 J
D. 0 J to 4 J

Answer:D
Explanation:
Hope I helped
When we plot the relation between kinetic energy and potential energy, we get an inverse line. The mechanical energy of an object is the sum of kinetic energy and potential energy. . The mechanical energy here is 5 J.
What is mechanical energy?Mechanical energy of an objects is the sum of it energy of motion and the stored energy of position, that is the sum of kinetic energy and potential energy.
Kinetic energy of an object result from its motion whereas potential energy results from the position of the object. Both kind of energy depends on the mass of the object.
Kinetic energy also depends on the velocity of the object and potential energy depends on the height and gravity experienced by it. Both are thus directly proportional to the mass of the object.
Here, all the points in the graph have a total energy of 5 J . for example for the first point the sum is 0 +5= 5J. Similarly, all the points have a total of 5 J.
Therefore, the mechanical energy of the system is 5J and the option B is correct.
