Complete the two-column proof. Diagram Two horizontal lines that appear to be parallel are cut by a transversal. Where the transversal intersects the top horizontal line, the angle in the top right corner is obtuse and labeled with a 2. Where the transversal intersects the bottom horizontal line, the angle in the top left corner is acute and labeled with a 1, the angle in the bottom left corner is obtuse and labeled with a 4, and the angle in the bottom right corner is acute and labeled with a 3. Drawing not to scale. Given: Angle 2 is congruent to angle 4, the measure of angle 2 is 110 degrees Prove: m angle D equals 70 degrees Statement Proof Angle 2 is congruent to angle 4, the measure of angle 2 is 110 degrees Given measure of angle 2 equal to measure of angle 4 Definition of congruent angles m angle 4 equals 110 degrees a. m angle 3 and m angle 4are a linear pair Definition of a linear pair (shown in diagram) m angle 3 and m angle 4are supplementary Linear Pair Postulate m angle 3 plus m angle 4 equals 180 degrees b. m angle 3 plus 110 degrees equals 180 degrees Substitution Property m angle D equals 70 degrees c.

both adhesion and cohesion are attractions.

they are different in that adhesion is the force of attraction between the molecules of two different substances, whereas cohesion is the force of attraction between molecules of the same substance.

possible examples include capillary action, in which the adhesion between water and glass causes the water to rise in a narrow tube against the force of gravity.

because of hydrogen bonding, water is extremely cohesive.

this causes molecules on the surface of water to be drawn inward, which is why drops of water form beads on smooth surfaces.

hope this .

as given the equation is

2al + 6 hcl > 2 alcl3 + 3 h2(g)

as per equation two moles of aluminum reacts with six moles of hcl to give two moles of alcl3 and three moles of hydrogen gas

given: three moles of al are present and 7 moles of hcl

for three moles of aluminum nine moles of hcl will be required

however as 7 moles of hcl are present so the limiting reagent is hcl

hcl is going to decide the number of moles of product formed

when six moles of hcl are present = 3 moles of h2 are formed

when one mole of hcl is present == 3/6 mole sof h2 will be formed

when 7 moles of hcl are present = 3 x 7/ 6 moles of h2 will be formed = 3.5 moles of h2
