There are several formulas for distance. The one you choose to use is the one that expressed distance in terms of the information that you already have.
For example, if you already know the speed and the time you've been traveling, then the formula for the distance you've covered is
D = (speed) times (time) .
Answer:
Same number of valance electrons
Explanation:
All of them are in group 1 so they have 1 valance electron.
If they were in same period they would have same number of energy levels.
C3H8 +5O2 ____> 3CO2 + 4H2O
44g of C3H8 will give 132g of CO2
355g will give 1065g
Answer is: H+ will increase and OH− will decrease.
pH = 11.4.
pH = -log[H+].
[H+] = 10∧(-pH).
[H+] = 10∧(-11.4).
[H+] = 4·10⁻¹² mol/L.
[H+] · [OH-] = 1·10⁻¹⁴ mol²/dm⁶.
[OH-] = 0.0025 mol/L.
pH value (potential of hydrogen - [H+]) is a logarithmic scale that specify the acidity or basicity of an aqueous solution.
When pH is greater than seven, aqueous solution is basic, below seven is acidic and when pH is equal seven, solution is neutral.
