Answer:
I believe it's j, convergent plate boundaries
The type of plate boundary that forms snowy mountains are convergent plate boundaries. option J is correct.
What are convergent plate boundaries?The convergent plate boundaries are which consist of two plates that move toward each other which results in the process called collision of two plates with each other.
The snowy mountains are full of snow which melts due to the change in temperature and leads to the formation of different plates and boundaries and the collision of two continental plates leads to the formation of this.
Therefore, option J is correct, the type of plate boundary that forms snowy mountains are convergent plate boundaries.

According to collision and transition state theories, what is the importance of activation energy?
According to the collision theory, the following criteria must be met in order for a chemical reaction to occur: Molecules must collide with sufficient energy, known as the activation energy, so that chemical bonds can break.
Could I have branliest, heart with 5 stars
Thanks and have a happy Christmas
Collision theory expresses that substance responses (in the gas stage) happen because of crashes between reactants.
Importance of activation energy:To really start a reaction, impacts should be adequately lively (dynamic energy) to break compound bonds; this energy is known as the Activation energy. As the temperature rises, atoms move quicker and impact all the more energetically, significantly improving the probability of bond breakage upon crash.

what volume of water has a mass of 1 kg
Answer:
[tex]V=0.001\ m^3[/tex]
Explanation:
Mass, m = 1 kg
The density of water, d = 1000 kg/m³
We need to find the volume of water. The formula for the density of an object is equal to mass divided by volume. Its formula is :
d = m/V
V is the volume of water
[tex]V=\dfrac{m}{d}\\\\V=\dfrac{1\ kg}{1000\ kg/m^3}\\\\=0.001\ m^3[/tex]
So, the volume of water is [tex]0.001\ m^3[/tex].
Answer:
Volume of water has a mass of 1 kg is explained below in details.
Explanation:
One liter of h2O has a volume of approximately specifically one kilogram when estimated at its maximum frequency, which happens at about 4 °C. It observes, therefore, that thousand of a liter, recognized as one milliliter (1 mL), of h2O has a volume of about 1 g; 1000 liters of h2O has a volume of about 1000 kg (1 tonne).

Usually, cells will take between 5 and 6 hours to complete S phase. G2 is shorter, lasting only 3 to 4 hours in most cells. In sum, then, interphase generally takes between 18 and 20 hours. Mitosis, during which the cell makes preparations for and completes cell division only takes about 2 hours. Calculate the percentage of time spent in each phase by counting the total number of cells in each phase (total in interphase, in prophase, etc.) and dividing each by the total number of cells you counted. How do cancer cells differ in total time required for mitosis? Cancer cells produce 117 minutes faster than regular cells. ... Normal cells require 640 minutes during interphase, cancer cells only need 380. For prophase, cancerous cells need 15 minutes less than regular cells. Another hallmark of cancer cells is their "replicative immortality," a fancy term for the fact that they can divide many more times than a normal cell of the body. In general, human cells can go through only about 40-60 rounds of division before they lose the capacity to divide, "grow old," and eventually die 3.
What is the density of a block with a volume of 5 cm3 and a mass of 20 g?
Answer: 4g/cm^3 or 4000g/L (4kg/L)
Explanation:
I'm not sure what units the question intended so I put both. For the first one, the equation for density is mass/volume so I divided the 20g by 5cm^3 to get 4g/cm^3. Just in case those aren't the intended units for volume and is instead liters, one cm^3 equals one ml. In addition, there are 1000ml in every liter so you can determine the amount per liter by multiplying 4g/ml by 1000 to get 4000g/L or 4kg/L.

Which of the following best describes the relationship between the speed of sound and the type of medium?
A.
Sound travels slower in air because of the large distance between air particles
B.
Sound travels slower in solids because of the small distance between solid particles
C.
Sound travels slower in air because of the small distance between air particles
D.
Sound travels slower in solids because of the large distance between solid particles
Answer:
A. Sound travels slower in air because of the large distance between air particles
Explanation:
Sound is a mechanical wave that requires a medium for its propagation. Without a medium, sound cannot go through easily or readily. This implies that sound cannot be propagated through a vacuum.
A vacuum is an empty space without any particles in side. Sound waves travel fastest the most in solids because the particles are dense and close to one another. The speed of sound in air is the least because of the large distance between air particles. Therefore, the speed of sound is medium dependentWhat effects do winds patterns have on climate
Prevailing winds bring air from one type of climate to another. For example, warm winds that travel over water tend to collect moisture as they travel; the water vapor in the air will condense as it moves into colder climates, which is why temperate coastal areas often receive heavy rainfall.

CaO + H2O -> Ca(OH)2
3.50g of Ca(OH)2 was made from 4.20g of CaO? What is the % yield of Ca(OH)2?
The % yield of Ca(OH)₂ : 62.98%
Further eplanationPercent yield is the compare of the amount of product obtained from a reaction with the amount you calculated
General formula:
Percent yield = (Actual yield / theoretical yield )x 100%
An actual yield is the amount of product actually produced by the reaction. A theoretical yield is the amount of product that you calculate from the reaction equation according to the product and reactant coefficients
Reaction
CaO + H₂O ⇒ Ca(OH)₂
mass CaO= 4.2 g
mol CaO(MW=56,0774 g/mol) :
[tex]\tt mol=\dfrac{mass}{MW}\\\\mol=\dfrac{4.2}{56,0774 g/mol}\\\\mol=0.075[/tex]
mol Ca(OH)₂ based on mol CaO
mol ratio CaO : Ca(OH)₂,= 1 : 1, so mol Ca(OH)₂ = 0.075
mass Ca(OH)₂(MW=74,093 g/mol) ⇒ theoretical
[tex]\tt mass=mol\times MW\\\\mass=0.075\times 74,093 g/mol\\\\mass=5.557~g[/tex]
% yield :

What is an atom?
An atom is defined as the smallest unit of matter which forms an element. Every form of matter whether solid,liquid , gas consists of atoms . Each atom has a nucleus which is composed of protons and neutrons and shells in which the electrons revolve.
The protons are positively charged and neutrons are neutral and hence the nucleus is positively charged. The electrons which revolve around the nucleus are negatively charged and hence the atom as a whole is neutral and stable due to presence of oppositely charged particles.
Atoms of the same element are similar as they have number of sub- atomic particles which on combination do not alter the chemical properties of the substances.

Answer:
beneath the surface of Earth
Explanation:
Diamonds are made up of carbon that has been placed under extreme heat and pressure conditions.
These conditions of high pressure and temperature can only be found within the subsurface. As you go deeper to the mantle, the geothermal gradient rises significantly.
Also, the overburden pressure will also be high.
These processes can also occur on other planets and some can be associated to the earth times when the earth was being formed.
The condition at which diamond forms confers some of the distinct natural properties that typifies it.

Answer:
The name of the two parts found on the left side of the equation is reactants.
Explanation:
Chemical reaction is the way one substance reacts against another. That is, a chemical reaction is that chemical process in which two or more substances, by the action of an energy factor, are converted into other substances. The new substance (s) that are formed usually present a totally different appearance from that of the starting substances.
In a chemical reaction there are the substances that react, that is, the reactants, and the substances produced, called products.
A chemical reaction is represented by a chemical equation. The formulas of the reactants are written on the left, and those of the products on the right, both separated by an arrow indicating the direction of the reaction.
Reactants ⇒ Products
Then, the name of the two parts found on the left side of the equation is reactants.
