Atoms consist of three basic particles: protons, electrons, and neutrons. The nucleus (center) of the atom contains the protons (positively charged) and the neutrons (no charge). The outermost regions of the atom are called electron shells and contain the electrons (negatively charged).

I can help. First you want to write out each reactant and product with enough space to write in coefficients. Then box the reactants and products to emphazise how the elements shouldnt change. Afterwards, draw a line in front of the box for you to write in the coefficients.Now we srart balancing. To make things easier, you should always follow the method of : (Metals, Nonmetals,Oxygen,Hydrogen) in that order. By balancing each elememt/chemical this way it should make balancing them easier.
So to acryally perform it you're going to look at your first element (while still following the method) and then look over onto the other side to see what coefficient to place. Then after that element is balanced, you move onto the next element. Remember that everytime you balance an element, start over to make sure all of the other elements are still balanced before proceeding.
Answer:
Waves carry energy from place to place.
Explanation:
Some waves are used for mainly communication and phone signals. They help people get internet in the middle of nowhere if you are near an energy wave.
Answer:
V₂ = 21.3 dm³
Explanation:
Given data:
Initial volume of gas = 3.00 dm³
Initial pressure = 101 Kpa
Final pressure = 14.2 Kpa
Final volume = ?
Solution;
The given problem will be solved through the Boly's law,
"The volume of given amount of gas is inversely proportional to its pressure by keeping the temperature and number of moles constant"
Mathematical expression:
P₁V₁ = P₂V₂
P₁ = Initial pressure
V₁ = initial volume
P₂ = final pressure
V₂ = final volume
Now we will put the values in formula,
P₁V₁ = P₂V₂
101 Kpa × 3.00 dm³ = 14.2 Kpa × V₂
V₂ = 303 Kpa. dm³/ 14.2 Kpa
V₂ = 21.3 dm³
