A 2.200-g sample of quinone (C6H4O2) is burned in a bomb calorimeter whose total heat capacity is 7.854<span> kJ/°C. The temperature of the calorimeter increases from 23.44 to </span>30.57 °C<span>. </span>
I’m sorry I didn’t understand can you please add more details please thank you
Volume of a sphere = 4/3 x pi x r^3
When put a fraction of volume constant 4/3 x pi cancels out.
So only cube of radii remains.
Radius of proton = 10^-15 m (Fact; remember it)
Radius of total Hydrogen atom = 0.529 × 10^−10 m
Fraction of Volumes : R'^3/R^3 = (R/R)^3
Fraction = ((10^-15)/(0.529 × 10^−10m.))^3= (1/52900)^3 =
6.755 x 10^-15
Answer:
345 converted to kilograms is 0.345
Explanation:
345 divided by 1000 is 0.345
Answer:
it is option 2.
Explanation:
when balancing equations, both sides need to have the same number of the element.
4As + 3O2 - -> 2As2O3
4 as. 4 as (2×2=4)
6 o (because 3×2=6) 6 o (2×3=6)
since there are the same amount of each element on both sides, the equation is balanced.
hope this helps:)
