How far is the earth from the sun?A. 1 parsec
B. 1 kiloparsec
C. 1 light-year
D. 1 AU

Answers

Answer 1

Answer:

The distance between the Earth and the Sun is approximately 1 AU (Astronomical Unit). Therefore, option D is correct.

What is astronomical unit ?

One AU is defined as the average distance between the Earth and the Sun, which is about 93 million miles (150 million kilometers). It is a convenient unit of measurement for distances within our solar system.

A parsec is a unit of distance used for objects outside our solar system, equal to approximately 3.26 light-years. One kiloparsec is equal to 1,000 parsecs, or approximately 3,260 light-years. Therefore, neither A nor B is the correct answer.

A light-year is the distance that light travels in one year, which is approximately 5.88 trillion miles (9.46 trillion kilometers). Therefore, C is also not the correct, as the distance between the Earth and the Sun is much less than one light-year.

Therefore, the correct answer is D. 1 AU

Answer 2

Answer: The answer should be 1 AU as it’s just about close to the number of miles from earth to sun.
Earth to sun in miles is -92.96
1 AU is- 92955807.3

How many moles of H2O are there in 1.0 g of H2O?

Answers

To calculate this, we need the molar mass of water which is obtaine by adding the molar masses of the elements. For H2O, the molar mass is 18.02g/mol. Then, from the amount given which is 1 gram of H2O we divide the molar mass which yields to 0.06 mol of water.

Lewis Structure of HOClO

Answers

At first you need to draw the lewis dots around each atom that you have.
Next thing that you should do is to connect the dots of HOClO and do not forget that each dot connect with one lone electron.
Then draw valence of each electron and connect them with a line.

Final answer:

The Lewis structure of HOClO consists of a hydrogen atom bonded to an oxygen atom, which is in turn bonded to a chlorine atom. Two chlorine atoms are also bonded to each other in the structure.

Explanation:

The Lewis structure of HOClO can be determined using the concept of valence electrons. Oxygen (O) has 6 valence electrons, Chlorine (Cl) has 7 valence electrons, and Hydrogen (H) has 1 valence electron. Based on this, the Lewis structure of HOClO can be represented as follows:

H - O - Cl - O

Where the oxygen atom is bonded to the hydrogen atom and the chlorine atom, and the two chlorine atoms are bonded to each other, resulting in a single bond and two double bonds.
