I think its A. it cant be C or D b/c we are measuring the distance between Earth and Saturn, not the speed.
Answer:
Boron has a larger radius and the protons in carbon exert more pull.
Explanation:
Remember than elements have greater radius as they are closer to the bottom left corner, so boron would have the larger radius here. Carbon has a smaller radius, which makes it easier for the protons in carbon to exert more pull.
An acid, acids have a pH less than 7
Water can be split into O2 and H2 gas
Answer and Explanation:
The primitive atmosphere of Earth may have favored the abiotic synthesis of organic molecules because it **had close to no oxygen, hence, it was powerfully reducing. It had pure energy sources too in form of ultraviolet rays from the sun (it was extremely hot! Too hot for water in liquid form to exist in fact!), outgassing from the numerous volcanoes and lightning**.
Abiotic synthesis means a formation reaction where the reactants are charged to become products, almost all on their own, with no catalyst especially.
So, these factors would have helped the organic molecules to form as most of what is needed to overcome the energy barrier and become products.
