10. The diagram below shows the present-day location of South America and Africa. Remains (1 point) of the extinct reptile Mesosaurus have been found in both locations. Which statement is the
most logical conclusion to draw from this evidence?
Africa
South America
Areas where Mesosaurus fossils have been found.
O Mesosaurus migrated across the ocean from South America to Africa.
O Mesosaurus came into existence on several widely separateoxontinents at different times.
The continents of South America and Africa were joined when Mesosaurus lived.
The present climates of South America and Africa are similar.

Consider three unlabeled bottles, each contain small pieces of one of the following metals. - magnesium - sodium - silver the following reagents are used for identifying the metals. - pure water - a solution of 1.0 molar hcl - a solution of concentrated hno3 (a) which metal can be easily identified because it is much softer than the other two? describe a chemical test that distinguishes this metal from the other two, using only one of the reagents above. write a balanced chemical equation for the reaction that occurs. (b) one of the other two metals reacts readily with the hcl solution. identify the metal and write the balanced chemical equation for the reaction that occurs when this metal is added to the hcl solution. use the table of standard reduction potentials (attached) to account for the fact that this metal reacts with hcl while the other does not. (c) the one remaining metal reacts with the concentrated hno3 solution. write a balanced chemical equation for the reaction that occurs. (d) the solution obtained in (c) is diluted and a few drops of 1 m hcl is added. describe what would be observed. write a balanced chemical equation for the reaction that occurs.

Compare and contrast physical changes with chemical changes.

If i initially have a gas at a pressure of 12 atm, a volume of 23 liters, and a temperature of 200 k, and then i raise the pressure to 14 atm and increase the temperature to 300 k, what is the new volume of the gas?
