Answer:
Light changes speed in a glass of water.
Explanation:
Answer : Option C) An induced dipole will be produced in the molecule on the right.
Explanation : As per the given information there is a polar molecule which is placed on the left side which has partial positive charge at one end and on other end has partial negative charge which shows that it has a dipole in it. It tries to induce the non-polar molecule which is at right side. So, there will be an induce dipole interaction between both when they are placed closer to each other.
The correct answer is A
Filter out the sand, because the sand does not dissolve in water, and then evaporate water from sugar solution
Answer:
4.99 x 10⁻⁷ meters or 499 nanometers
Explanation:
Use the formula:
λ = c/ν, where λ = wavelength, c = the speed of light (it's constant, 2.998 x 10⁸ m/s), and ν = frequency
λ = (2.998 x 10⁸ m/s)/(6.01 x 10¹⁴ 1/s)
λ = 4.98835 x 10⁻⁷
Round to nearest hundreth and you get 4.99 x 10⁻⁷ meters, or 499 nanometers.
Answer:
3 moles
Explanation:
This question is on stoichiometry of reactions
Given
2H₂ +O₂⇒2H₂O-------------------the equation is balanced
<u>Find the mole ratio</u>
2H₂ +O₂⇒2H₂O
2 1 2
O:H = 2:1---------------------------------every mole of hydrogen requires two moles of oxygen to complety react
Thus given 6 moles of hydrogen;
O:H
?:6
=6/2=3 moles
