Answer: NOT accurate, but precise.
[translation: You screwed up, but did it in style].
Explanation:
The average mass measurement is 41.95g. Compared to the actual value of 28.0 grams, the measurement is NOT accurate.
The standard deviation for the data is 0.112. Dependiong on your definition of precision, this looks relatively good. I would go for precise.
Answer is: <span>3. they conduct electricity.
1) acids taste sour, bases taste bitter.
2) acid </span><span>would react with metals and produce hydrogen gas:
Ca(s) + 2HCl(aq) </span>→ CaCl₂(aq) + H₂(g).
3) Acids and bases give ions in water solutions, so <span>they conduct electricity.
</span>
An Arrhenius base is a
substance that dissociates in water to form hydroxide ions (OH⁻<span>).
In this example lithium hydroxide is an Arrhenius base:</span>
LiOH(aq) → Li⁺(aq) + OH⁻(aq).
An Arrhenius acid is a
substance that dissociates in water to form hydrogen ions or protons (H⁺<span>).
For example hydrochloric acid: HCl(aq) → H</span>⁺(aq) + Cl⁻(aq).
4) red litmus turn blue whe base is drop on it and blue litmus turn red when acid is drop on it.
5) bases have pH greater than 7, acids have pH less than 7.
Is there something else that goes along with the question?
N2 + 3H2 ---> 2NH3
nitrogen + hydrogen ---> ammonia
ANSWER:A.blood
WHY: because it make the most sense and it seem right
