Answers

The scientist thought that the atom was the smallest particle in the universe is John Dalton. He established the atomic theory which consists of five; elements are made of extremely small particles called atoms, atoms of different element have different sizes, mass and physic – chemical properties, atoms cannot be divided further, destroyed or created, atoms can combine to form compounds and in chemical reaction, atoms can be combined, separated or rearranged.

Answer:

all atoms of one type were identical in mass and properties

Help please Isabella was standing directly below a power line, and her compass failed to give an accurate reading.

How could she explain why her compass was not working?

A

A compass works with a magnetic field, and the electric current running through the lines above it would interfere with the magnetic field.

B

The compass works because of an electric field, and the electric current running through the lines above would interfere with the electric field.

C

The compass works because of a gravitational field, and the magnetic current running through the lines above would interfere with the gravitational field.

D

A compass works because of a magnetic field, and the magnetic current running through the power lines above it would interfere with the magnetic field below it.

For the Haber process,N2+3H2 yields 2NH3, what volume of Nitrogen is consumed at STP if you collect 44.8 L of ammonia in excess hydrogen (N=14 AMU, H=1 AMU)a. 14.9 L
b. 29.9 L
c. 44.8L
d. 22.4 L

Answers

Answer: d. 22.4 L

Explanation:

$N_2+3H_2\rightarrow 2NH_3$

According to Avogadro's law , 1 mole of every gas occupies 22.4 L of volume at STP.

moles of ammonia= $\frac{\text {given volume}}{\text {Standard Volume}}=(44.8)/(22.4)=2moles$

Given: Hydrogen is the excess reagent and nitrogen is the limiting reagent as it limits the formation of product.

From the given balanced equation:

2 moles of ammonia is produced by 1 mole of nitrogen.

Thus 2 moles of ammonia is produced by 22.4 L of nitrogen at STP as 1 mole of nitrogen occupies 22.4 L at STP.
