Which of these characteristics best describes a basic solution?

1 answer:

5 0

I believe the correct answer would be that it feels slippery. Being slippery or soapy is one characteristic of a base. This due to the fact that it dissolves the oils and fatty acids from the skin. Other characteristics would be that it turns litmus paper blue and has a bitter taste.

Suppose a snack bar is burned in a calorimeter and heats 2,000 g water by 20 °C. How much heat energy was released?

prohojiy [21]

Heat energy released : 167.2 kJ

<h3>Further explanation</h3>

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

m = 2000 g

c = 4.18 J/ g ° C

∆t = 20 ° C

$\tt Q=2000\times 4.18\times 20\\\\Q=167200~J=167.2~kJ$
