The table below shows some physical properties of two unknown samples . physical properties sample volume freezing point 1000 0 c b 1000 -95 c what would best support whether the two es are of the same substance or not ? the two substances are the same because their intensive property is the same . the two substances are the same because their extensive property is different the two substances are not the same because their extensive property is the same . the two substances are not the same because their intensive property is different

When light strikes a plane mirror, images form in locations where light does not actually reach. it only appears to the observer as though the light were coming from this position. what type of image is formed?

What type of reaction is illustrated? 2c12o5 = 2cl2 + 502

Construct the hypothetical phase diagram for metals a and b between room temperature (20c) and 700c, given the following information: * the melting temperature of metal a is 480c. • the maximum solubility of b in a is 4 wt% b, which occurs at 420c. • the solubility of b in a at room temperature is 0 wt% b. • one eutectic occurs at 420c and 18 wt% b–82 wt% a. • a second eutectic occurs at 475c and 42 wt% b–58 wt% a. • the intermetallic compound ab exists at a composition of 30 wt% b–70 wt% a, and melts congruently at 525c.• the melting temperature of metal b is 600c. • the maximum solubility of a in b is 13 wt% a, which occurs at 475c. • the solubility of a in b at room temperature is 3 wt% a.
