Why is Alka-Seltzer a base?
Alka-Seltzer contains sodium bicarbonate and citric acid. The sodium citrate acts as an antacid. Excess sodium bicarbonate from the Alka-Seltzer acts to neutralize base.
Answer:
713mmHg
Explanation:
By using Dalton's law of partial pressure, the pressure outside the gas container is equal to the pressure inside it and this pressure equals the sum of the pressures of water and the gas.
i.e, P(total) = P(gas) + P(water)
P(gas) = P(total) - P(water)
P(gas) = 735 - 22
P(gas) = 713mmHg
Answer:
D: Increasing the amount of water.
Explanation:
Choice A: increasing the pressure can force the liquid to stay a liquid and affect the boiling point (decrease it).
Choice B and C: both involve colligative properties, adding a solute to water will increase the boiling point of water.
Choice D: just having more water does not change the boiling point of the water as this minimize the effect of any external factor.
<em>So, the right choice is: D: Increasing the amount of water.</em>
combustion reaction are always exothermic in nature...so heat liberated is one of way to identify it
