Answer:
It will lead to a decrease in the boiling points
Explanation:
Decreasing the pressure exerted on a compound reduces d boiling points because a high temperature is needed also to boil a compound
Wood can be natural source of heat just as coal is however, coal releases chemicals and spoke (which causes smog- nasty poluted fog) wood on the other hand is more natural and does not release any harmful chemicals into the air
Answer:
393.1 KPa
Explanation:
Now we have to use the general gas equation;
P1V1/T1 = P2V2/T2
P1= initial pressure of the gas= 1.00atm
V1 = initial volume= 700.0 ml
T1= initial temperature= 0.0°C +273= 273K
V2= final volume= 200.0 ml
T2= final temperature =30.0°C +273= 303 K
P2= final pressure =????
Therefore;
P2= P1V1T2/ V2T1
P2= 1.00 × 700.0 × 303/ 200.0 × 273
P2= 3.88 atm
But
1 atm = 101.325 kilopascals
Therefore 3.88 atm = 3.88 × 101.325 kilopascals = 393.1 KPa
Answer: Physical change
Explanation: Quite simple as the starfish opening a clam would mean the starfish is physically changing the clams look.
Answer:
2 hydrogen and 1 oxygen
Explanation:
H2O
Hydrogen has the coefficient so you multiply 1 by 2 and it equals 2
Oxygen does not have any sub or coe so its automatically 1
