Answer: 122.5088
Explanation:
1 mole of H2O = 2(1.008)+1(16) = 18.016
6.8 moles of H2O = 6.8×18.016 = 122.5088
Answer : S) 33.2 °C
Explanation : When the equal amounts of gases are placed in identical containers but subjected to different temperatures would exert pressure in different amount which will in turn increase the rate of collision between the molecules of gas.
So, when the temperature is increased to maximum greater amount of force would be exerted and the gas molecules will collide with a larger force. Hence the answer will be as the highest temperature i.e. 33.2 °C
Hi,
This change is physical because there is no new formation of a new substance or any signs of a chemical change, only the physical properties change.
Answer:
Hydrochloric acid + sodium → sodium chloride + water
NaOH +HCl → H2O and NaCl
Explanation:
salt is a neutral ionic compound. Let's see how a neutralization reaction produces both water and a salt, using as an example the reaction between solutions of hydrochloric acid and sodium hydroxide. The overall equation for this reaction is: NaOH +HCl → H2O and NaCl.
