Answer:
E. Fracking
Explanation:
The process involves the high-pressure injection of 'fracking fluid' into a wellbore to create cracks in the deep-rock formations through which natural gas, petroleum, and brine will flow more freely.
Answer:
Explanation: tellurium has an atomic mass of 127.6 whilst the element that comes after it, iodine, is lighter with an atomic weight of 126.9. Mendeleev concluded that the atomic mass for one of these two elements must be wrong because tellurium clearly preceded iodine in the periodic table
Yes, a reaction will occur. Potassium chloride react with bromine to produce potassium bromide and chlorine would take place in a boiling solution.
Answer:
there is 1 leftover because your adding to 1... I think
Explanation:
Answer is: the HCO3⁻ to act as a base and remove excess H⁺ by the formation of H₂CO₃.
Dissociation of carbonic acid: H₂CO₃(aq) ⇄ HCO₃⁻(aq) + H⁺(aq).
Adding acid: HCO₃⁻(aq) + H⁺(aq ⇄ H₂CO₃(aq).
A buffer can be defined as a substance that prevents the pH of a solution from changing by either releasing or absorbing H⁺ in a solution.
Buffer is a solution that can resist pH change upon the addition of an acidic or basic components and it is able to neutralize small amounts of added acid or base, pH of the solution is relatively stable.
