I think the correct answer would be D. The reaction that involves an acid and a covalent base would be the reaction of sulfuric acid and water or H2SO4 + 2H2O → 2H3O+ + SO42– . The acid would be H2SO4 and the covalent base would be H2O since it is being held by covalent bonds and when in solution it will have equal amounts of OH- and H+ ions.
Hey there! :D
This is a true statement. Gamma radiation comes from electromagnetic energy from radioactive decay. This decay has the shortest electromagnetic wave lengths and therefore has the highest photon energy. It is extremely dangerous. Radiation in general is something to be cautious of!
I hope this helps!

Answer:
Sum of coefficients in balanced equation is 18
Explanation:
Unbalanced equation:
Balance O:
Balance C:
Balanced equation:
Sum of coefficients in balanced equation = (1+8+1+8) = 18
So, option (4) is correct.
<h2>Answer:</h2>
The three examples of convection are
- The stack effect
- Oceanic circulation
- Hot air balloon
<h2>Explanation:</h2>
The stack effect is also referred to as the chimney effect which is the movement of air inside and outside of buildings, flues or any other objects because of buoyancy principle. In oceanic circulation warm water around the equator circulates towards the poles and the cooler water at the poles moves towards the equator. In hot air balloon, a heater inside the balloon heats the air and so the air moves upward.
