13-ethyl-3-methoxy-gona-2 5(10)-diene-17-one is Methoxydienone. An anabolic steroid is a type of chemical called methylstenbolone. It is turned into testosterone and other hormones by the body.
There is no good scientific evidence to support the use of methandienone for weight loss, improving athletic performance, level of testosterone, or any number of other purposes. Infertility, behavioral changes, hair loss, and breast development (in men) are some of the side effects. Methoxydienone can likewise prompt liver harm and coronary illness

substances can be categorised in two ways: as an element, mixture or compound ora as a solid, liquid or gas. which
of these methods Is of most use ti chemist?
Answer:
Most substances on earth are compounds and most interesting chemistry is done with compounds. Most interesting chemistry is done with mixtures of compounds although they often start with pure compounds and then do reactions as mixtures. Most chemistry is carried out in liquid solutions made up of compounds that are solids, liquids, or gases in their pure form.
Explanation:
Here, we are required to determine which of these methods of classifying substances is most important to chemists.
The most useful classification of compounds to chemists is as Elements, Compounds or MixturesFirst classification of substances involves categorising them as pure substances (elements and compounds) or mixtures.
The second classification of substances is categorisation with respect to their state of matter. In essence, we can have solid, liquid or gas.
However, the most useful classification of compounds to chemists is as Elements, Compounds or Mixtures.This is so because, the type of matter present in Elements are distinct for each element, same as for Compounds and Mixtures formed from a combination of pure substances.
Chemists focus on the diverse properties of substances, as such classification as elements, compounds and mixtures provides a wide basis for the qualitative and quantitative analysis of the properties of substances.Classification of substances as solid, liquid or gas leaves a narrow avenue for the study of substances as the substance still contains the same type of matter, only this time in different states.Read more:

Solid potassium chlorate breaks into potassium chloride and oxygen gas when heated up to high temperature. This is an example of a/an _______ reaction.
Answer:
es correcto bro claro eres un crak
Answer:
Decomposition Reaction
Explanation:
You can determine the type of reaction by writing out a balanced equation.
Solid Potassium Chlorate: KClO3
Potassium Chloride: KCl
Oxygen Gas: O2
Balanced Equation: 2KClO3 -> 2KCl + 3O2
By definition, a decomposition reaction is when a single substance decomposes into two more simpler substances. AB -> A + B
Because the solid potassium chlorate is breaking into two substances, potassium chloride and oxygen gas, it is a decomposition reaction.

Wendy wants to find out if a substance is an acid or a base. What are two ways that Wendy could
investigate to find out what kind of substance it is?
Without tasting a colorless liquid, an acid or a base can be determined using indicators.
The three most common indicators to test for acids and bases are: Litmus. Methyl orange. Phenolphthalein.
How do you know something is an acid?One practical method for determining how acidic something is is to use the pH scale. A solution is acidic if its pH is less than 7. If the pH of the solution is 7, it is neutral; if the pH is greater than 7, it is basic.To identify acids and bases, two types of litmus paper are available: red litmus paper and blue litmus paper. When exposed to acidic conditions, blue litmus paper turns red, while red litmus paper turns blue when exposed to basic or alkaline conditions.

Which phrase describes runoff?
1.underground water that flows into lakes
2.river water that empties into an ocean
3.water from streams that flows into larger rivers
4.water from rain and snow that travels to streams
Please help!
Explanation:
water from rain and snow that travels to streams
Please help!
Water from a rain and snow that travels to streams are examples of run off. These natural processes are part of water cycle and balance the water content in the atmosphere and hydrosphere.
What is water cycle ?Water cycle is a geological phenomenon to balance the water content in the atmosphere, hydrosphere and in the biosphere. The water bodies evaporate by the heat radiated by sun.
The air moisture can be restored to the land through the cooling of the vapor and pour as rain. This best illustrates the interaction between atmosphere and hydrosphere.
Rain, snow, sleet, or hail that reaches a surface stream without ever going below the soil's surface is referred to as surface runoff. It differs from direct runoff, which is runoff that directly reaches surface streams following rainfall or snowmelt. Hence option 4 is correct.

how many moles are in 3.0x10^24 molecules of water
Answer:
3.52 x 10^24 molecules x `1mol/6.02 x 10^23 molecules = 5.85 moles of H2O.
Explanation:
If the molecular mass of a substance is 7.304 • 10²³ g, find its molar mass.
Answer:
1.213 g/mol
Explanation:
We are given that the molecular mass is 7.304 × 10²³ g.
From avogadro's number, we know that;
1 mole of a substance = 6.022 × 10²³ molecules
Thus;
Molar mass = molecular mass/avogadro's number = (7.304 × 10²³)/(6.022 × 10²³) = 1.213 g/mol

1. What major change in our thinking about the path of a moving electron had to be made with the advent of quantum theory?
2. Calculate the wavelength of a space shuttle with a mass of 2.05 x 107kg traveling at a rate of 7.85 x 103 m/s.
Answer:
See explanation
Explanation:
1) With the advent of the quantum theory came the idea that the path of a moving electron can not be exactly determined. We can only talk about the probability of finding the electron within a given region in space.
2) Using the De Broglie's relation;
λ = h/mv
Where;
λ = wavelength
h = Plank's constant
m = mass
v = velocity
λ = 6.6 * 10^-34/2.05 x 10^7 * 7.85 x 10^3
λ = 4.1 * 10^-25 m
how many mongo seed are equal to 3.50 moles of mongo seeds?
answer:
2.107 x 10^24 mongo seeds
Answer:
50 moles of many mango seeds = 2.107.10²⁴ mango
Further explanation
A mole is a unit of many particles (atoms, molecules, ions) where 1 mole is the number of particles contained in a substance that is the same amount as many atoms in 12 gr C-12
While the number of moles can also be obtained by dividing the mass (in grams) with the molar mass of element or molecule
With Avogadro's number
N = number of gas particles
No = Avogadro number (6.02.10²³)
n = number of moles
n= N/No
3.50 moles of many mango seeds are comparable to
N mango seeds= 3.5 x 6.02.10²³
N mango seeds=2.107 x 10²⁴..
How does gravity help to demonstrate a cause-and-effect relationship?
Answer:
Gravity helps show a cause and effect by demostarting how one object will have an effect on another object.
Explanation:
If you bounce a ball, it will fly back up, but it will fall down again because of gravity. The cause is GRAVITY and the effect is the ball FALLINg. Now, because o fgravity, when the ball bounces up again, it will only bounce 1/2 the hieght, having another cause and effect. As gravity pushes down on objects, the more an object is effected by it, the more presure it will have.
Explain why it is often necessary to start a campfire with many pieces of kindling (small pieces of wood) rather than with a few large logs
Answer:
It is often necessary to start campfire with many pieces of kindling rather than large logs because it is easier to ignite smaller pieces than larger pieces. Imagine wanting to light up a pile of clothes and a small piece of a shirt. Which ignites faster? The piece of a shirt, because it is smaller and more likely to burn very quickly. Additionally, people criss-cross these tiny pieces of wood to enable more surface area and to allow more oxygen to pass through. As you know, oxygen is necessary for a flame to ignite.
