Answer:
Hope this helps :)
Explanation:
1. A physical property is a characteristic of matter that is not associated with a change in its chemical composition.
2. Matter is everything around you. Atoms and compounds are all made of very small parts of matter.
3. Solid, liquid and, gas
4. False
5. Our weight on moon is less than it would be on Earth due to a difference of the strength of gravity on the moon.
6. Physical changes only change the appearance of a substance, not its chemical composition. Chemical changes cause a substance to change into an entirely substance with a new chemical formula. Chemical changes are also known as chemical reactions.
Explanation:
P1= 44 kpa
P2= 50 kpa
V1= 4.50 L
V2= ?
P1 V1= P2 V2
44 × 4.50 = 50 × V2
198= 50 × V2
V2 = 198/ 50
V2= 3.96 L "the new volume"
<u>Answer:</u> The reaction proceeds in the forward direction
<u>Explanation:</u>
For the given chemical equation:
Relation of 
is given by the formula:
where,
= equilibrium constant in terms of partial pressure = ?
= equilibrium constant in terms of concentration = 
R = Gas constant = 
T = temperature = ![35^oC=[35+273]K=308K](https://tex.z-dn.net/?f=35%5EoC%3D%5B35%2B273%5DK%3D308K)
= change in number of moles of gas particles = 
Putting values in above equation, we get:
is the constant of a certain reaction at equilibrium while 
is the quotient of activities of products and reactants at any stage other than equilibrium of a reaction.
The expression of for above equation follows:
We are given:
Putting values in above equation, we get:
We are given:
There are 3 conditions:
- When
; the reaction is product favored. - When
; the reaction is reactant favored. - When
; the reaction is in equilibrium
As, 
, the reaction will be favoring product side.
Hence, the reaction proceeds in the forward direction
Answer:
A hurricane can cause extreme damage to the biosphere and the geosphere. A hurricane can leave water standing therefore sinking itself into the geosphere. The biosphere can be permanently effected because it can kill, injure, and destroy the biosphere and what the biosphere creates (buildings, parks).
