The ___ variable responds to the __ variable and goes on the Y-axis.
1. Dependent, Independent
2. Independent, Dependent
3. Control, Constant
4. Constant, Control

Answers

Answer: 1. Dependent, Independent The dependent variable responds to the independent variable and goes on the Y-axis.

Explanation: The independent variable is controlled or manipulated by the experimenter. For example, someone's age might be an independent variable. Other factors (such as what they eat, how much they go to school, how much television they watch) aren't going to change a person's age.The dependent variable is what you are measuring. For example, a test score could be a dependent variable because it could change depending on several factors such as how much you studied, how much sleep you got the night before you took the test, or even how hungry you were when you took it.

How that helps. :)

The dependent variable responds to the independent variable and goes on the Y-axis. Therefore, option A is correct.

What is dependent variable ?

In mathematical modeling, statistical modeling, and experimental sciences, there are dependent and independent variables. Dependent variables are so-called because, during an experiment, their values are examined on the assumption or presumption that they are governed by the values of other variables.

the dependent variable on other measurable variables As a result of an experimental manipulation of the independent variable or variables, these variables should change.

What you track in the experiment and what is impacted by it are both considered dependent variables. The independent variable affects the dependent variable's behavior. Because it "depends" on the independent variable, it is known as a dependent variable.

Thus, option A is correct.

Answer:

30

Explanation:

CO2 means that there is 1 carbon and 2 oxygens  in each CO2 molecule.

If there are 10 atoms of Carbon that requires 20 atoms of oxygen.

The number of atoms present is 10 + 20 = 30 atoms of any kind present. You just need to add.

A compound contains 25.94%N and 74.06% O by mass whats the empirical formula

Answer:

hope this helps, love. have a good day

Explanation:

Empirical formula is the simplest whole number ration of elements in a compound. Molecular formula is n times the empirical formula, where n is integers 1,2,... Therefore, the empirical formula is NO[tex]_2[/tex].

What is Empirical formula?

Empirical formula gives the proportion of the element that is present in a compound. It does not give information about the actual number or the arrangements of the atoms.

The relation between molecular formula and empirical formula can be given as

n= molecular formula÷ empirical formula

Number of gram atoms in compound and divide by smallest Number of gram atoms in compound

N=(25.94%)÷14=1.85/1.85=1

O=( 74.06% )÷16=4.62/1.85=2

The atomic ratio is 1:2

Whole number N:O is1:2

Empirical formula corresponding to this whole number is NO[tex]_2[/tex].

Therefore, the empirical formula is NO[tex]_2[/tex].

It really depends on the situation. If you have 1000 elk and 2 wolves, they really would play a better role in killing off elk so that the elk population doesn't get over populated and diseased, causing a major population collapse. But if there were only 10 elk and 50 wolves, the wolves would play a very negative role on the population.

Answers

How many moles is 7.78 x 1024

formula units of MgCl2?

answer: 7966.72

Mole measure the number of elementary entities of a given substance that are present in a given sample. Therefore, there are 0.49moles of  MgCl[tex]_2[/tex] in  7.78 x 10²⁴atoms of MgCl[tex]_2[/tex] .

What is mole?

The SI unit of amount of substance in chemistry is mole. The mole is used to measure the quantity of amount of substance. It measure the number of elementary entities of a given substance that are present in a given sample. There are so many formula for calculating mole.

we know one mole of any element contains 6.022×10²³ atoms which is also called Avogadro number

mole =given number of atoms ÷ 6.022×10²³(Avogadro number)

given number of atoms of MgCl[tex]_2[/tex]= 7.78 x 10²⁴

Substituting the values

mole= 7.78 x 10²⁴÷ 6.022×10²³

mole = 0.49moles of  MgCl[tex]_2[/tex]

So, there are 0.49moles of MgCl[tex]_2[/tex] in  7.78 x 10²⁴atoms of MgCl[tex]_2[/tex] .

Answers

Answer:

due to warm temperature

Explanation:

Explanation:

There is water present in liquid form instead of liquid nitrogen on the outer side of the can because of the temperature present in the surrounding environment. The temperature around the can is little warm which is favourable for the water but not for the liquid nitrogen. The liquid nitrogen present in liquid state when the temperature of the surrounding is too cold. if it is warm, the liquid nitrogen starts boiling and converts into gaseous state so that's why the warmer temperature is responsible for the presence of water not the liquid nitrogen.

a sample of glucose contains 1.250x10^21 carbon atoms, how many atoms of hydrogen does it contain?

Answers

Answer:

Hydrogen = 2.5 * 10^21

Explanation:

Chemical Formula Glucose: C₆H₁₂O₆

One of the ways you could do  this is to notice that for every carbon atom there are two Hydrogen atoms. You can state this more formally by using the formula to set up a ratio: 12/6 = hydrogen to Carbon

So if there are 1.250 * 10^21 Carbon atoms in the Glucose sample, then there will be twice as many hydrogen atoms.

H = 2 * 1.25 * 10^21 = 2.5 * 10^21 atoms

You could do this more formally by setting up a proportion.

6 Carbon / 12 Hydrogen = 1.25*10^21 /  x         Cross Multiply

6*x = 12 * 1.25*10^21                                           Combine the right

6x = 1.5 * 10^22                                                  Divide by 6

x = 2.5 * 10^21
