Answer:
+3·F
Explanation:
The number of objects in the given system = 2 objects
The charge on each object are; q₁ = -Q, q₂ = -Q
The force acting between the objects = +F
The distance between the objects = 2·d
The formula for the force acting between two charged particles is given as follows;
Therefore, we get;
By tripling the charge, q₁, on the first object, we get;
q₂ = 3 × (-Q)
Therefore, the new force between them, F₂ = +3·F
Answer:
2C2H6 + 7O2 → 4CO2 + 6H2O
Explanation:
First off you find them by balancing the equation ( equal amounts of elements on both sides) So add a two infront of the C2H6. Now you have 4 Carbons and 12 Hydrogens on the left aswell as 2 oxygens.
Now go to the right side and put a 4 infront of CO2 and a 6 infront of H2O. You now have 4 carbons 12 hydrogens and 14 oxygens on the right side.
Finally go back to the let side and place a 7 infront to make the left have 14 oxygens just like in the right. A trick to use is to save the coefficients with only one element till the end so you can do less work in the long run.
But i hope this helped its balanced and down to the smallest whole numbers possible most teachers want whole numbers as the coefficient.
These are tricky at first but once you practice a bit you will be a pro.

Hi how are you doing today Jasmine
<u>Answer:</u>
h is planck's constant
c is the speed of light
λ is the wavelength of light
Wavelength
<em>Thus, the wavelength of light associated with the transition from n=1 to n=3 in the hydrogen atom is </em><u><em>103 nm.</em></u>
Liquid antacids contain suspensions of bases like aluminum hydroxide and magnesium hydroxide. These are usually the bases that can neutralize the stomach acids.
The chemical equation representing the neutralization reaction of stomach acid, HCl and antacid, aluminum hydroxide: Three moles of hydrochloric acid reacts with one mole aluminum hydroxide to give the salt, aluminum chloride and three moles of water.
