our sun is considered average because its temperature and absolute magnitude place it in the __ range of the H-R diagram

Chemistry

Vlad [161]3 years ago

Answer:

middle

Explanation:

When the stars are plotted on the Hertzsprung-Russell diagram, most of them  fall into the curve called the main sequence. The main sequence stars are 'average' because many stars fall into this category, and these stars burn hydrogen into helium in their core, and they are relatively young ( age of a few billion years) .

Our sun sits in the middle of the main sequence curve in the HR- diagram, which means the it is a yellow dwarf star with a  surface temperature of about 6000 K, it has an average size, and it is hot enough for hydrogen fusion—in other words a typical star.

Answer:

I know some of them...

Explanation:

1. What was the purpose of the experiment?

Type your answer here: The purpose of this experiment is to show that a cell membrane is a type of barrier, and is permeable to some substances, but may not be permeable to all substances.

2. What were the independent, dependent, and control variables in your investigation? Describe the variables used in the part of the experiment with the eggs.

Type your answer here: Independent variable / Manipulated variable: Refers to all the variables in an experiment that provoke a response in another variable. This variable is modified during the experiment to analyze how another variable responds to it. The researcher wants to study how the changes in these variables affect the dependent variable.  The researcher can change these variables to see what changes it implies in an object, process, trait, or anything that depends on them.

Dependent variable / Responding variable: Its response depends on any change in the independent variable. The dependent variable is the one that is being investigated, studied, and measured. It represents a quantity of something which value depends on how the independent variable is modified. It is usually identified by the letter Y.  A change in the dependent variable might be proportional or inversely proportional to the change in the manipulated variable. In the exposed example, the dependent variable is the egg circumference.

Constants / Controlled variables: Refers to those variables in an experiment that are controlled and have no influence on the results. These variables do not affect the change in the dependent variable values. In the exposed example the use of the lid to seal the jar and the amount and concentration of vinegar might be considered as a controlled variable. These elements are used but do not provoke any change in the size of the egg.

What mass in grams of SO2 is needed to react with 37.50 mol of Oz?
-BARSIC- [3]

Answer:

4804.5 g of SO₂ are needed to the reaction

Explanation:

The reaction to produce sulfuric acid is:

2SO₂ + O₂ + 2H₂O →  2H₂SO₄

Ratio is 1:2. 1 mol of oxygen needs 2 moles of sulfur dioxide in order to react. We can propose this rule of three.

If 1 mol of O₂ react to 2 moles of SO₂

Then, 37.50 moles of O₂ will react with (37.5 . 2) /1 = 75 moles of SO₂

We convert the moles to mass, to know the answer:

75 mol . 64.06 g / 1 mol = 4804.5 g of SO₂
