A. NO2 because the elements are both nonmetals.
Answer:
13 km
Explanation:
Distance travelled = 5 km + 3 km + 2 km + 3 km = 13 km
Continental drift is the movement of Earth’s continents over long periods of time. An evidence for this is that some continents look like puzzle pieces that can fit together, such as South America and Africa. Another evidence is that fossils of the same type have been found in different continents, far apart - suggesting that the two continents once were joined. Another evidence is that identical rocks were found at both sides of the Atlantic Ocean by Alfred Wegener, the main developer of the continents drift theory.
Answer:
Increasing the temperature of the reactants
Explanation:
This causes more vibrations to occur, hence increasing the kinetic energy of the particles. The number of particles with activation energy would increase as well because they have higher kinetic energy. Kinetic energy is also the reason why the collision between particles increases. And the frequency of effective collisions increases because of the kinetic energy as well, keep in mind the particles must also be orientated in the correct way as well.
