.90 dL is 90 mL because 1 dL is 100 mL
Wavelength is the distance of one frequency wave peak to the other and
is most commonly associated with the electromagnetic spectrum.[1]
Calculating wavelength is dependent upon the information you are given.
If you know the speed and frequency of the wave, you can use the basic
formula for wavelength. If you want to determine the wavelength of light
given the specific energy of a photon, you would use the energy
equation. Calculating wavelength is easy as long as you know the correct
equation.
<span>If the human body were a car, glucose would be the gasoline.
Glucose gives humans energy, we basically run on glucose, among other things, the same way a car would run on gas.

Answer:
Lithium
Explanation:
I believe it is Lithium. It can easily be cut with a knife and is the 3rd lightest non gas on the periodic table that is not a gas.
The volume of oxygen at STP required would be 252.0 mL.
<h3>Stoichiometic problem</h3>
The equation for the complete combustion of C2H2 is as below:
The mole ratio of C2H2 to O2 is 2:5.
1 mole of a gas at STP is 22.4 L.
At STP, 100.50 mL of C2H2 will be:
100.50 x 1/22400 = 0.0045 mole
Equivalent mole of O2 according to the balanced equation = 5/2 x 0.0045 = 0.01125 moles
0.01125 moles of O2 at STP = 0.01125 x 22400 = 252.0 mL
Thus, 252.0 mL of O2 gas will be required at STP.
