Answer:
Explanation:
1.026 g/204.23 g/mole= 0.00502 mole
0.00502/0.1 L= 0.0502 molar
We know, mole of gas in ideal conditions is 22.414 L
Here, CH4 volume = 8.9L
So, number of moles = 8.9 / 22.414 = 0.397 moles
Here, in balanced equation we have a ratio CH4 : H2O = 1:2.
So, mole so water = , 0.397*2= 0.794 moles
In liters it would be: 0.794 * 22.414 = 17.80 L
In short, Your Answer would be 17.80 Liters
Hope this helps!
Answer:
Air is a good insulator because the molecules are far apart. This reduces mobility of air molecules hence conduction is difficult.
Explanation:
For other statements :
- All the suns radiations are not reflected back to space because the ozone layer of the earth's atmosphere which regulates the intensity of radiations from the sun, it is transparent and porous hence heat and light rays from sun enter earth.
- Work is only done by potential energy when the body is under free fall and experiencing gravitational force, but for a body moving without influence of gravity, work is done by the force applied and the distance moved by the body. This force is called a <em><u>c</u></em><em><u>o</u></em><em><u>n</u></em><em><u>s</u></em><em><u>e</u></em><em><u>r</u></em><em><u>v</u></em><em><u>a</u></em><em><u>t</u></em><em><u>i</u></em><em><u>v</u></em><em><u>e</u></em><em><u> </u></em><em><u>f</u></em><em><u>o</u></em><em><u>r</u></em><em><u>c</u></em><em><u>e</u></em><em><u>.</u></em>
- Total mechanical energy is given by
= <em><u>Kinetic energy + Potential energy</u></em>
Heat of vaporization of water = 540 cal/g
m=1000 g
energy supplied = 5.4 kcal=5400 cal
T1=T2=100 deg. C
so all energy is used to convert to steam
mass of steam produced = 5400 cal /(540 cal/g)
=5400/540 cal *g/cal
=10 g
