Answer:
The reaction forming aluminum bromide is Al + 3Br2 → 2AlBr3
Answer:
Explanation:
Diiodine pentoxide is I₂O₅
Reaction with water
I₂O₅ + H₂O = 2HIO₃
2 ) HIO₃ is called iodic acid.
Answer:
The correct answer is physical properties and/or phase properties.
Explanation:
Chemical properties can alter the substance (if you burn wood, it becomes ash and is no longer wood).
Reactive properties are also chemically changing the substance.
Phase properties are where the element can be in solid, liquid, or gas form so these could also be an answer.
Answer : The density of the block is estimated to be, 
.
Explanation :
Density of the water, 
As we know that,
Buoyant force = 
where,
g = gravitational acceleration
volume of the block = v
density of the block = 
Weight of the Block = Buoyant force exerted by water
Thus, the density of the block is estimated to be, .
Answer:
P₂ = 1000 atm
Explanation:
Given data:
Initial volume of air = 200 L
Initial pressure = 100 atm
Final volume = 20.0 L
Final pressure required = ?
Solution:
The given problem will be solved through the Boly's law,
Mathematical expression:
P₁V₁ = P₂V₂
P₁ = Initial pressure
V₁ = initial volume
P₂ = final pressure
V₂ = final volume
Now we will put the values in formula,
P₁V₁ = P₂V₂
100 atm × 200 L= P₂ × 20.0 L
P₂ = 20,000 atm. L/ 20.0 L
P₂ = 1000 atm
