1. For the reaction A → B, the rate law is: rate = kx [A]. Over the course of 4 minutes, the concentration of A reduces by one-half,
from 1.00M to 0.5OM. How is the rate affected?
The rate reduces by a factor of 0.50k.
The rate reduces by a factor of 1/2.
The rate reduces by a factor of 1/8.
The rate increases by a factor of 2.

Hey : )a transition from the first energy level to the fourth energy level

Starsstars are giant balls of hot gases that can produce their own light. stars give out energy by converting hydrogen gas into helium in their cores. stars are gigantic in size and have immense gravitational attraction. the sun is a medium sized star that gives us energy and makes life on earth possible.planetsplanets are large (almost) spherical objects that revolve around the sun. planets move in fixed orbits around the sun. there are 8 planets in our solar system. planets may be made of rocks, metals, gases like hydrogen, nitrogen and methane. the earth is also a planet and is the only place in the universe that we know that supports life. planets that revolve around other stars are called exoplanets.satellitessatellites are objects that revolve around planets. they form the essential part of the celestial bodies. these may be of natural origin or sent by humans. the moon is a natural satellite of the earth and revolves around it because it is bound by the earth’s gravitational pull. man also has placed artificial or man-made satellites around the earth and other planets to study them and for communication purposes.i think this is correct not 100%

False alkali metals and alkali metals are highly reactive and most of them have to be covered in a layer of oil to be kept as they react on exposure to air.

According to the laws of gravity it is directly proportional to the mass of the body's involved and inversely proportional to the distance between the two objects, that is the closer it is the more strongly will the two objects pull each other and the larger the mass involved the stronger the force of attraction.
