(3) Cl2(g) <==> Cl2(l), because it has an equilibrium between the two phases of liquid and gas.
The appropriate answer is C. Both are formed by gravitational forces. The first picture shows an elliptical galaxy. These galaxies can be round, nearly spherical or flattened disks. They contain very little dust or gas and the stars contained here are older than stars in other galaxies. The second picture shows a spiral galaxy that has a center made up of a thick mass of material and has flattened arms that rotate around the center.
Galaxies are formed from the gravitational pull of massive objects in space. Some galaxies from around super massive black holes (spiral) or a group or collection or cluster of stars.
Answer:
0.5 or .5
Explanation:
The answer to number 3 is 0.5 and here's why:
you have to divide the voltage by the resistance right so you would divide 1.5 by 3 to get 0.5
Answer:
Yes a soap is a salt
Explanation:
The process of soap production is called saponification. Saponification is the hydrolysis of fats and oils with a caustic alkali such as NaOH or KOH to yield the corresponding sodium or potassium salt of the fatty acid and propane 1,2,3-triol.
Recall that organic salts are compounds of the sort RCOO^-M^+ (such as RCOO^-Na^+). A soap is of the same RCOO^-Na^+ (or K^+) structure indicating that it is a salt where R is the alkyl chain of the fatty acid.
Activation Energy. All chemical reactions, even exothermic reactions, need a certain amount of energy to get started. This energy is called activation energy. For example, activation energy is needed to start a car.
