1. What properties of metals makes them useful in these applications?
(a) Aluminum is used to make the outside surface
of some car doors.

(b) Thin gold wires are used to connect one part of
a computer chip to another.

(C) The bottoms of some frying pans are made of
copper
This is science

(C) The bottoms of some frying pans are made of copper.

Explanation:

As metal have the property that they can conduct heat within them , hence the bottom of frying pans are made of copper so that they can conduct much of the heat and use it for the cooking efficiently.

the equation that correctly represent the reaction for formation of ammonia is

n2+ 3h2 → 2nh3 (answer d)

1 mole of nitrogen gas (n2) react with 3 moles of hydrogen gas (h2) to form 2 moles of ammonia ( nh3). this is in a process known as haber process were iron is used as a catalyst and reaction take place that a higher temperature and pressure. the process is exothermic hence energy is released.
