B. pure substance made of two or more elements
C. can be represented by a chemical formula
D. different samples have different properties

Answers

Answer:

I think it's D

sorry if I'm wrong.

Explanation:

Options that are not characteristics of compound in the question is D. different samples have different properties.

A compound can be regarded as a substance which is formed by chemical  combination of two or more elements.Examples of compound are water ( H2O), Sodium chloride ( NaCl)

Some of the properties of a compound are;

A compound will always has a different properties which is different from the properties of each of the elements making up the compound.A compound are formed as a result of  two or more elements that combined chemically.A compound can be identified with its chemical formula.

When 3.00 grams of methane, CH,, reacts according to the balanced equation below, how many molecules of water are produced?
CH, + 202 - CO2 + 2H20

Answers

Answer:

2.41×10²³ molecules of water

Explanation:

Given data:

Mass of methane = 3 g

Molecules of water formed = ?

Solution:

Chemical equation:

CH₄ + 2O₂    →     CO₂  + 2H₂O

Number of moles of methane:

Number of moles = mass/ molar mass

Number of moles = 3 g/ 16 g/mol

Number of moles = 0.2 mol

Now we will compare the moles of water with methane.

               CH₄           :              2H₂O

                  1              :                  2

                0.2            :             2 × 0.2 = 0.4 mol

Molecules of water:

1 mole = 6.022×10²³ molecules of water

0.4 mol ×6.022×10²³ molecules of water / 1mol

2.41×10²³ molecules of water

How does the atomic mass of the atom change when an electron is added or removed?

Answers

If you could magically make two neutrons in the nucleus of an atom disappear, the atomic number and the electrical charge of that atom would remain unchanged. Neutrons do not carry an electrical charge so adding or removing them from the nucleus does not change the electrical charge of the nucleus. It does, however, change the mass of the nucleus. Adding or removing neutrons from the nucleus are how isotopes are created.

Protons carry a positive electrical charge and they alone determine the charge of the nucleus. Adding or removing protons from the nucleus changes the charge of the nucleus and changes that atom's atomic number. So, adding or removing protons from the nucleus changes what element that atom is! For example, adding a proton to the nucleus of an atom of hydrogen creates an atom of helium. (Actually, a few neutrons have to be added as well to make the new nucleus stable, but the end result is still helium.) Keep in mind that atoms, by definition, are electrically neutral and always contain the same number of protons and electrons.

Spongebob completed his experiment. He wrote a brief summary about the investigation. He also determined that his hypothesis statement was not right and explained why it wasn't right by providing evidence from the investigation. Spongebob utilized which step of the scientific method?

Answers

Answer:

In a 7-step scientific method, Spongebob utilized the 6th step when He wrote a brief summary of the investigation, and Spongebob utilized the 7th step when He also determined that his hypothesis statement was not right and explained why it wasn't right by providing evidence from the investigation.

Explanation:

Scientific Methods are organized ways employed by scientists to tackle problems by providing solutions to the problem or make hypotheses to which other scientists build on to provide solutions to the problem.

The steps of the scientific method are:

Step 1- Understand the Problem

Step 2-  Make research

Step 3- Hypothesis.

Step 4- Conduct an experiment to test the hypothesis

Step 5- Observations.

Step 6-Results/Conclusion.

Step 7- Communicate your research

When Spongebob wrote a brief summary of the investigation, which means he had already conducted an experiment and had already made necessary observations and data collection, so he was at step 6. At step 6, he had analyzed the data collected.

When Spongebob determined that his hypothesis statement was not right and explained why it wasn't right by providing evidence from the investigation, then he was at the final step of the scientific method. Step 7 tells whether the hypothesis is true or false.
