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.
Answer:
Jet streams are fast flowing, narrow, meandering air currents in the atmospheres of some planets, including Earth
Explanation:
The formula of work is Work (Joules)=Force (Newtons) · distance in the direction of the force (meters), therefore its just a matter of replacing factors.
Work done = 12 · 4.5= 54 joules
A function describing the location and wave-like behavior of an electron in an atom.
The final temperature of the mixture : 21.1° C
<h3>Further explanation </h3>
The law of conservation of energy can be applied to heat changes, i.e. the heat received / absorbed is the same as the heat released
Q in(gained) = Q out(lost)
Heat can be calculated using the formula:
Q = mc∆T
Q = heat, J
m = mass, g
c = specific heat, joules / g ° C
∆T = temperature difference, ° C / K
Q ethanol=Q water
mass ethanol=
mass water =
then the heat transfer :
