When magnesium ribbon is placed in sulfuric acid, a chemical reaction takes place and heat energy is given off.
Liang and Naranbaatar are planning an investigation into the effect of the
length of magnesium ribbon on the increase in temperature. They decide to
carry out some preliminary work.
Explain what preliminary work they could do and how this would help them
plan their investigation.​

Each of the following reactions is allowed to come to equilibrium and then the volume is changed as indicated. predict the effect (shift right, shift left, or no effect) of the indicated volume change. drag the appropriate items to their respective bins.co(g) + h2o(g) < => co2(g) + h2(g) (volume is decreased) pcl3(g) + cl2(g) < => pcl5(g) (volume is increased) caco3(s)< => cao(s) + co2(g) (volume is increased)

The biosphere of the earth is made up of what compound? organic or inorganic?

Which answer tells the reason the earth’s climate is getting warmer? too many animals are becoming extinct. large glaciers are melting in antarctica. the earth is moving closer to the sun. driving cars gives off gases that trap heat in the atmosphere.
