Answer:
you would be trapped in the gravitational pull of a black hole
Explanation:
there is a black hole in the center of the galacy
Answer:
It would have a charge of +2.
Explanation:
A proton has a charge of +1, an elctron has a charge of -1, and a neutron has a charge of 0. Ignore the neurons since they have a charge of 0. Since there are 20 protons and 18 electrons (20-18), the overall charge of the atom is +2.
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.
To solve average speed? You can either make a quad or take your total distance and divide it by your total time/ and that would give you your total average speed! Your average speed would be Mp/H<span />
Answer:
PbSO4 is not a covalent compound.
Explanation:
PbSO4 is an ionic compound.
