Whenever electrons are shared or transferred between atoms there is a chemical reaction.
The electrons that are being transferred between atoms (two or more) create new bonds, which enable the production of a new substance. This process is then known as a chemical reaction.
PH of solution will be greater than seven (pH>7), that means that solution is basic (<span>pH above </span>7<span> is a base, the higher the number, the stronger is the base).
</span>pH (potential of hydrogenis) is a measure of the hydrogen ion (H⁺) concentration of a solution. <span>Solutions with a pH less than 7 are acidic.</span>
F---atomic number 9---1s2 2s2 2p5 -----7 electrons
The answer is an acid.
That is a substance that gives up a proton during a chemical reaction, raising the hydrogen ion concentration of water, is most appropriately called an acid.
Acid is a substance that gives protons in its aqueous solution, and that the hydrogen ion concentration of that aqueous solution .
Answer:
This is an exothermic reaction
q = 563 kJ
Explanation:
Step 1: The balanced thermochemical equation
H2CO(g) + O2(g) → CO2(g) + H2O(l) ΔH = -563 kJ
This is a combustion, this means there will be released heat. This means it's an exothermic reaction.
The energy involved, will be released (that's why ΔH is negative)
q has the same value as ΔH (but positive)
q = 563 kJ
