Answer:
85.076572
Explanation:
= (84.911789×0.7217) + (86.909183×0.2738)
= 85.076572
Answer:
The answer is option A
Explanation:
This is because the measure from crest to crest is also known as the wavelength, and the color of a wave always depends on its wavelength, if you see the electromagnetic spectrum
Hope this helps!
<span>The law of conservation of mass states that, "Mass can neither be created nor destroyed, only its form changes with respect to different forms of energy."
In any reaction, say 10 gms of water is decomposed into its constituents Hydrogen and Oxygen. But the mass remains conserved for the reaction. Although mass and energy are inter-convertible. But,the net mass/energy remains conserved i.e. the mass of products will be equal to the mass of reactants. </span>
Under standard temperature and pressure conditions, it is known that 1 mole of a gas occupies 22.4 liters.
From the periodic table:
molar mass of oxygen = 16 gm
molar mass of hydrogen = 1 gm
Thus, the molar mass of water vapor = 2(1) + 16 = 18 gm
18 gm of water occupies 22.4 liters, therefore:
volume occupied by 32.7 gm = (32.7 x 22.4) / 18 = 40.6933 liters
