Answer:
Because frequency and wavelength are related by a constant (c) the energy can also be written in terms of wavelength: E = h · c / λ.
Assume that the concentration of stock is 1.0 M
And initial volume = 16.0 ml
final volume = 0.310 L or 310 ml
therefore
CiVi = CfVf
1.0 *16 ml = Cf * 310 ml
Cf = 1.0*16/310
= 0.052 M
Thus dilute solution is 0.052 M times dilute to concentrate solution
Answer: 1.5 moles O2
Explanation:
The number of moles of each reactant and product is the number in front to the molecule when the equation is balanced.
You know that 1 mole of O2 gives you 2 moles of H2O
So you can set up a proportion using that.
1 mole O2. X moles O2
-------------- = -------------------
2 moles H2O. 3 moles H2O
Then cross multiply
2x=3
X=3/2 Or 1.5
So you need 1.5 moles O2 to get 3 moles of H2O.
They have to form a chemical bond in order to brake them down first
<h3><u>Answer;</u></h3>
Formation
<h3><u>Explanation;</u></h3>
- <em><u>Formation is the fundamental sedimentary rock unit which can normally be traced for long distance.</u></em>
- <em><u>Sedimentary are one of the major types of rocks which results from deposition followed by cementation of mineral or organic particles on the ocean floor or other bodies on the surface of the earth.</u></em>
- Formation is the fundamental sedimentary rock unit. These types of rocks are formed from deposition of sediment out of air, water, ice, gravity or water flows carrying suspended particles that form from weathering process.
