Answer:

Mass =12.4g

∆T= 1064-26

=1038°C

H=mc∆T + mlf

where c =Specific heat of substance

lf= Latent heat of Fusion

m=Mass

∆T=Temp. change

Substituting

H= 12.4(0.1291)(1038) + 12.4(63.5)

H= 1661.67 + 787.40

H=2449.07J

Arturiano [62]

Answer:

21) There is a 0% chance of picking a 13 in a deck of cards. <u>Impossible.</u>

If there is a 0% chance that something will happen then it is impossible.

22) There is a 50% chance of picking a red card in a deck of cards.<u> Equally likely.</u>

If there is a 50% chance that something will happen, it is equally likely that it will happen.

23) There is an 80% chance of snow tomorrow. <u>Likely or certain.</u>

If there is an 80% chance of something happening, it means that the chances of that thing happening good and the event is likely to occur.

24) There is a 20% chance of rain tomorrow. <u>Unlikely.</u>

A low chance of 20% means that something is unlikely to occur.
