Help please!!!!!!!!!!!!
Answer:
D
Explanation:
Gases have low densities. Density is the mass of an object divided by its volume. Mass of gases are quite small. Since the mass is related to mass of the particles itself. However the volume is great since the gases are far apart due to how weak the forces of attraction are ( gases take the shape of the container which means they take up a good bit of space which means greater volume). A small mass divided by a large volume gives a small value (small density).
Why do atoms become anion and cations (remember the octet rule and how 8 is a very important number)?
Answer:
The atoms become cations because they have lost electrons and the atoms and has a positive charge then atoms become a ions because they have gained electrons from cations and has a negative charge

What is IUPAC nomenclature?IUPAC nomenclature of organic chemistry is a method of naming organic chemical compounds as given by the International Union of Pure and Applied Chemistry (IUPAC).
There are 3 main parts of IUPAC nomenclature -
1. Prefix
2. Root word
3. Suffix
We have to select the longest continuous chain in a compound and give prefixes as the substituents. Root word will the part which depends on no. of carbon atoms such as meth or eth. And in suffix we focus on type of carbon chain whether it is saturated or not and also the functional group.
Here, we can say that the numbering will be started from the carbon having triple bond and it is present at first position.
Therefore, The name of this molecule is 1-butyne. D is correct.

Answer:
A common characteristic of most Alkali Metals is their ability to displace H2(g) from water. This is represented by their large, negative electrode potentials. In this event, the Group 1 metal is oxidized to its metal ion and water is reduced to form hydrogen gas and hydroxide ions. The general reaction of an alkali metal (M) with H2O (l) is given in the following equation:2M(s)+2H2O(l)⟶2M+(aq)+2OH−(aq)+H2(g)(1)

A
condensing
B
evaporating
C
freezing
D
melting
Answer:
a
Explanation:
The molecules of a substance formed a rigid repeating crystal structure. Then, a phase change occurred. That structure is now more like clusters of molecules moving past one another this change is caused by condensing phase.
What is condensing phase ?The transformation of water vapor into liquid is known as condensation. The process is the opposite of evaporation, in which liquid water turns into a vapor. Either the air is chilled to its dew point or it gets too saturated with water vapor to retain any more water, causing condensation to occur.
By removing and transferring heat from the vapor to a cooling medium, condensation is the process by which a substance goes from its vapor phase to its liquid phase. The vapor must be saturated for the process to begin as well as having its vaporization heat reduced.
Thus, option A is correct.

how do you scale a recipe by changing the portion size
Answer:
You must change the size of each ingredient by the size of the product. Let's say my recipe calls for 1 bag of flower and 2 eggs. I want to double the amount of product that I make, so I must multiply each of my ingredients by 2. I would now use 2 bags of flower and 4 eggs.

Answer: In a vacuum, the objects fall at the same rate independent of their respective masses. That means coin and feather both reach ground at same time in a vacuum. Larger objects experience more air resistance than smaller objects. Also, the faster an object falls, the more air resistance it encounters.

C. the outer core is less dense and closer to the surface than the mantle
D. the outer core is less dense and farther from the surface the. the mantle
Answer: A. the outer core is more dense and farther from the surface than the mantle
Explanation: There are two mantle‘s. But both of them are closer to the surface than the outer core. the outer core is the liquid layer outside of the inner core. The mantle is the next layer after the outer core. It goes: inner core, outer core, stiffer mantle, asthenosphere, ridged mantle, then the earth’s crust.
What happens to the salinity and temperature of ocean water as the depth increases?
A. The salinity and temperature of ocean water remain the same as depth increases.
B. The salinity and temperature of ocean water increase as the depth increases.
C. The salinity of ocean water decreases and the temperature of ocean water increases as the depth increases.
D. The salinity of ocean water increases and the temperature of ocean water decreases as the depth increases.
Answer: D
Explanation:
I would say D, because it makes sense for the temperature to decrease with depth because less sunlight means less heat. I'm not sure about the salinity 100% but I think it increases.

When a cube of manganese oxide was added to a solution of hydrogen peroxide, water and oxygen were produced. Manganese oxide was not used up in the reaction. Which of the following is likely to increase the rate of the reaction? (5 points)
Reducing the mass of the cube
Using a smaller amount of solution
Smashing the cube into pieces
Chilling the hydrogen peroxide solution
Answer:
Smashing the cube into pieces
Explanation:
The reason for this is that if we were to smash the cube we would have a larger surface area which means more manganese oxide would be dissolving per second which means we would have a faster reaction rate where if we were to chill the peroxide it would dissolve slower which in turn slows the reaction. For example a spoonful of granulated sugar will react with water faster than a sugar cube.
The rate of the reaction is increased by smashing the cube into pieces. C is the correct answer.
What is the reaction rate?The reaction rate, also known as the rate of reaction, is the rate at which a chemical reaction occurs.
It is typically classified as proportional to the change in product concentration per unit time and the change in reactant concentration per unit time. Different chemical reactions have different reaction rates.
The amount of reactants, the temperature, and the catalyst all influence the reaction rate.
When a cube of manganese oxide was added to a solution of hydrogen peroxide, water and oxygen were produced, just as in the given reaction. The reaction did not deplete manganese oxide.
The reaction will be altered by smashing the cube into pieces as the it can boost appropriate conditions for the reaction.
Thus, C is the correct answer.

What is symbiosis?Symbiosis is a close relationship between two species in which at least one species benefits.
For the other species, the relationship may be positive, negative, or neutral.
There are three basic types of symbiosis: mutualism, commensalism, and parasitism.
Mutualism is a symbiotic relationship in which both species benefit. Commensalism is a symbiotic relationship in which one species benefits while the other species is not affected.
One species typically uses the other for a purpose other than food. Parasitism is a symbiotic relationship in which one species (the parasite) benefits while the other species (the host) is harmed.
Therefore, a pearlfish spends the day inside the alimentary tract, or intestines, of a sea cucumber. The fish emerges from the sea cucumber at night to feed on small crustaceans. The pearlfish gets a safe place to live. The sea cucumber does not gain anything from the relationship, nor is it harmed. This is similar to the relationship between bees and plants or sea anemonies and clownship and the correct option is option D.

How many molecules of Na2O are in 24.6g? Show work!
Answer:
Explanation:
Na2O has 2 atoms of Sodium and 1 atom of Oxygen
So, the molecular mass of Na2O is:
(2 x Atomic weight of Na) + (1 x Atomic weight of O)
Atomic weight of Na = 22.99 g
Atomic weight of O = 16 g
Therefore, Molecular Mass of Na2O = (2x 22.99g) + (1 x 16g)
= (45.98 + 16)g = 61.98 g
Therefore 61.98 g of Na2O contains 6 x 10^23 molecules (Avogadro's number).
24.6 g of Na2O therefore contains:
(24.6/61.98) x 6 x 10^23 = Answer!
