I believe the correct answer from the choices listed above is option B. When equal masses of each are added to water, ethylene glycol would be more effective. Ethylene glycol is the most widely used automotive cooling-systemantifreeze, although methanol, ethanol, isopropyl alcohol, and
propylene glycol are also used.
Hope this answers the question. Have a nice day.
Answer:
Mass of sodium hydroxide needed = 28.2 g
Explanation:
Given data:
Mass of sodium hydroxide = 80 g
Mass of sodium sulfate produced = 142 g
Mass of sodium hydroxide needed = ?
Mass of sodium sulfate produced = 50 g
Solution:
Mass of sodium sulfate produced / Mass of sodium hydroxide = Mass of sodium sulfate produced / x
142 g/ 80 g = 50 g / x
x = 50 g × 80 g / 142 g
x =4000 g/ 142
x = 28.2 g
Answer:
The forces involved in a collision are equal in size and directed in the opposite direction, and they accelerate both objects. Each object accelerates equally in collisions with things of equal mass.
Explanation:
Chlorine because it lacks one valence electron to fill it's outer shell
The answer for that is 16, math right?
