8 points Transition metals have high densities, have high melting points, form type your answer... compounds and often act as type your answer... as elements and in compounds. Most of them are type your answer... typical metallic-looking substances. However, in contrast, their compounds are often type your answer... colored. They have type your answer... or type your answer... valence electrons.

Drag each label to the correct location on the chart. classify each reaction as endothermic or exothermic.

Which statements are true concerning mineral formation? check all that apply. the slower the cooling, the larger the crystals. the faster the cooling, the smaller the crystals. crystals formed from magma are smaller than crystals formed from lava. minerals can only form in solutions when the solution is heated deep underground. when a solution cools, elements and compounds leave the solution and crystallize as minerals. minerals formed from hot water solutions can form narrow channels in the surrounding rock.

Choose an equation that represents an enzyme-catalyzed reaction. (a) enzyme + substrate → enzyme-substrate complex (b) enzyme + substrate ←−→ enzyme + products (c) enzyme + substrate ←−→ enzyme-substrate complex → enzyme + products (d) enzyme + substrate ←−→ enzyme-substrate complex → enzyme-substrate complex + products
