What is the momentum
of an 800-kg car
| traveling at a velocity
of 10 m/s? what is its
momentum if it speeds
up to 50 m/s? ​

this is the partial pressure of ar in the flask. a 1.00 l flask is filled with 1.20g of argon at 25 degrees c. a sample of ethane vapor is added to the same flask until the total pressure is 1.400atm .

both theories and laws could potentially be falsified by countervailing evidence. theories and laws are also distinct from hypotheses. unlike hypotheses, theories and laws may be simply referred to as scientific fact.

answer: option (c) is the correct answer.

explanation:

catalyst are the substances which in increasing the rate of a chemical reaction without itself getting consumed.

a catalyst changes the path of a reaction by lowering the activation energy level so that molecules with low energy can easily participate in the reaction and thus, formation of products become fast.

thus, we can conclude that out of the given options, a catalyst increase the speed of a reaction as the catalyst makes it easier for the activated complex to form, lowering the activation energy.
