A 50 g block of metal has an original temperature of 35.0°C and a specific heat value of 0.45 J/g.°С. What will be the final temperature of this metal if 800 J of heat energy are added?

What reaction is taking place? 02 + c3h8 = h20 + co2

Classify this reaction: 2al+n2-> aln.

According to the kinetic-molecular theory, what happens to a liquid when it is transferred from one container to another? the volume and the shape stay the same. the volume increases to fill the new container, but the shape stays the same. the volume stays the same, but the shape changes to fit the new container. the volume and the shape change to fill the new container.
