Given- m= 1.75 g
Now moles of O2 gas= Mass/ Molar mass
n = 1.75/32
V= 2L
P= 1atm
R=0.0821.....Constant
As PV=nRT
=> T=PV/nR
= 1* 2/ (1.75/32)*0.0821 K
= 2*32/1.75* 0.0821 K
= 445.45 K
= (445.45- 273.15) degrees celsius
= 172.30 degrees celsius..... ANSWER
Answer:
Atom - un átomo de hidrógeno pierde un electrón, adquiere una carga positiva
Molecule - Al aumentar el calor, las moléculas se alejan en mayor medida unas de otras y se intensifica su estado de agitación.
To find heat, you need the following formula
heat= specific heat x mass x ΔT
specific heat (for water)= 4.184--> according to the table
mass= 100 grams
ΔT= 75 -10= 65 °C
let's plug the values.
specific heat= 4.184 x 100 x 65= 27200 joules or 27.2 Kilojoules
