Awedge, which is used to split objects, distributes the force applied on its blunt face as shown in the image.

the distribution of force occurs because

a) a wedge has three flat faces.
b) the sides of the wedge are inclined.
c) most of the force is absorbed by the blunt face.
d) the applied force is felt only at the sharp edge.

When the volume and number of particles of a gas are constant which of the following is also constant

Why is carbon ideal for making different compounds?

Modern pennies are composed of zinc coated with copper. a student determines the mass of a penny to be 2.482 g and then makes several scratches in the copper coaling (to expose the underlying zinc). the student puts the scratched penny in hydrochloric acid, where the following reaction occurs between the zinc and the hcl (the copper remains undissolved): zn(s) + 2 hcl(aq) → h2(g) + zncl(aq)the student collects the hydrogen produced over water at 25 °c. the collected gas occupies a volume of 0.899 l at a total pressure of 79 j mmhg. calculate the percent zinc (by mass) in the penny. (assume that all the zn in the penny dissolves.)
