Answer:
Sulfuric acid has a higher density than water, which causes the acid formed at the plates during charging to flow downward and collect at the bottom of the battery.
Answer:
Starch is a viable indicator in the titration process because it turns deep dark blue when iodine is present in a solution. When starch is heated in water, decomposition occurs and beta-amylose is produced
<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.
Answer:
69.8 %.
Explanation:
2Na + Cl2 = 2NaCl
Using Relative Atomic Masses:
2*22.99 g sodium should produce 2*(22.99 + 35.45) = 116.88 g of sodium chloride
So 5.75 g Na should give 116.88 * 5.75 / 2*22.99 g = 14.62 g NaCl
% yield = 10.2 / 14.62 = 69.8%.
