Answer:
The correct answer is - D. Red, green, violet.
Explanation:
Visible light is the spectrum of light that can be seen by the naked eyes of humans without any equipment. This spectrum has various frequency light that helps us see things in color. The frequency of light ranges between seven different colors in which violet has the highest frequency and red has the lowest.
The different frequencies are as follows:
color frequency
red (limit) 1.77
red 1.91
orange 2.06
yellow 2.14
green 2.25
cyan 2.48
blue 2.75
violet (limit) 3.10
On this basis of this the group of colors of the visible light is listed from
lowest to the highest frequency - Red, green, violet
Answer:
Balancing of equation involves making sure the number of atoms of an element on the left hand side(reactant) is equal to the number of atoms of an element on the right hand side(product)
4NH3 + 14O2 → 4NO2 + 6H2O
In the equation above,the number of Oxygen on the left is (14*2)=28 while the number of oxygen on the right is (4*2+6)=14. This makes it an unbalanced equation.
The temoerature decreases because the average kinetic energy is always linearly related to temperature
Explanation:
(a) The molecular equations shows the equation in which all the species of the reactants and the products are in molecules and the net charge is zero.
The complete ionic equations shows the equation in which all the species of the reactants and the products are in dissociated form and are represented as ions.
The net ionic equations shows the equation in which all the species of the reactants and the products are in dissociated form and do not show the spectator ions which are same in the reactants and the products.
(b) If there is no spectator ions in the reaction, then the complete and the net ionic equations would be identical.
Answer:
B
Explanation:
If the student needs one gram but so far only has 0.37 grams, then the amount they need is the difference between what they need and how much they already have. 1-0.37=0.63 grams.
...which isn't actually an option because none of them have decimal points but I would say it is B anyway because it is the equivalent ratio and maybe there was a typo.
Hope this helped!
