how many significant figures in 1. 19.99 2. 140486 3. 0.0609 3. 5.08 ?

Answers

1. 4 significant numbers

2. 6 significant numbers

3. 3 significant numbers

4. 3 significant numbers

Further Explanation  

Significant numbers are numbers obtained from the measurement results of exact numbers and the last number estimated  

1. 19.99

all non-zero numbers are significant numbers , so there are 4 significant numbers

2. 140486

a zero which is located between two non-zero numbers including a significant number , so there are 6 significant numbers

3. 0.0609

a zero in front of a decimal point is not a significant number, so there are 3 significant numbers (6,0 and 9)

4. 5.08

Any zeros between two non-zero numbers are significant, so there are 3 significant numbers(5,0 and 8)

How are hypotheses different from theories?

Answers

Answer:

Explanation:

This is the Difference Between a Hypothesis and a Theory. In scientific reasoning, a hypothesis is an assumption made before any research has been completed for the sake of testing. A theory on the other hand is a principle set to explain phenomena already supported by data.

If Beryllium has a mass number of 7 and atomic number of 4, how many protons does it have?

Answers

Answer:

4

Explanation:

Answer:

4

Explanation:

So the atomic number is still the proton number and it is always smaller than the atomic mass so the proton number is 4.

Which of the following can be inferred from the diagram above that shows the dependence of potential Energy on the Internuclear distance between two atoms?

A - The atoms form a bond with a bond length of 25 pm
B - The atoms form a bond with a bond length of 75 pm
с - The net force between the atoms is attractive at 25 pm
D - The net force between the atoms is attractive at 75 pm

Answers

Answer:

B - The atoms form a bond with a bond length of 75 pm

From the potential energy diagram of shown, we can infer that the atoms form a bond with a bond length of 75 pm.

When atoms are far away from each other, there exists no interaction whatsoever between the atoms.

However, as the atoms draw closer to each other, the potential energy diagram begins to shift towards an energy minima as we can see from the potential energy diagram.

As the system continues to tend towards this minima, the distance between the atoms decreases. The distance at which the two atoms have the lowest energy is called the bond length.

For this system, such a bond length occurs at 75pm as we can see from the diagram.

Describe the motion of molecules in each of the three states of matter.

Answers

Answer:

EASSSSSYYY give me a harder question smh

if you want you can give me Brainliest answer lol

Explanation:

A solid’s particles are packed closely together. The forces between the particles are strong enough that the particles cannot move freely.

A liquid is a fluid that conforms to the shape of its container but that retains a nearly constant volume independent of pressure. The volume is definite (does not change) if the temperature and pressure are constant.

Gas molecules have either very weak bonds or no bonds at all, so they can move freely and quickly. Because of this, not only will a gas conform to the shape of its container, it will also expand to completely fill the container.

How many grams are there in 1.18 X 1026 atoms of iridium?

Answers

You want to divide by avagadros number (6.22 x 10^23). This will cancel the atoms unit and give moles, moles of Iridium. Now you want to calculate the atomic mass of Iridium which is in units of grams per mole. Multiply these two numbers and the moles will cancel giving you grams.

Setting up a dimension analysis type of thing helps tremendously. See what you have to cancel in order to get what you want. We canceled the atoms, then we canceled the moles, and then we got grams.
