Answer:
What is the net ionic equation for a reaction between HCl and NaOH?
Explanation:
A 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
Hope that helped.
Answer 1
Correct Option: <span>A) The water received more energy than the alcohol.
Reason:
In the present case, the heating rate of both water and alcohol was same. So same amount of heat was supplied, at any given point of time. However, water took more time to reach the temperature of 50 oC. This clearly depicts that, more amount of heat was supplied to water, as compared to alcohol, to reach the desired temperature. It also suggest that, w</span>ater
takes longer to change its temperature than the alcohol<span>

Answer 2:
Correct option: </span> For the same temperature change, water requires more energy<span>
Reason:
In the present case, time required for water to achieved the same temperature as that of alcohol, at a constant heating rate, was more. This suggest that f</span>or the same temperature change, water requires more energy. This can be attributed to the fact that, hydrogen bonding in water is more stronger than that in alcohol. Due to this, more amount of energy is required to overcome hydrogen-bonding in water.
Answer:
Explanation:
IONIC-
metal & nonmental
1st word doesn't start with "mono"
2nd word can end in "-ate or -ite" (Polyatomic ions)
May need roman numerals
Reduce charges when writing formula
COVALENT-
2 non-metals
Names uses prefixes
2nd word can end in - ide
BOTH-
2nd element is a non-metal
I just took a test with this question and got the answer wrong for saying ethane. The correct answer is propane.
