B- ammonia. ammonia has a pH level of about 11, and anything higher than 7 is more basic and anything less than 7 is more acidic. 7 is considered neutral.
The answer is
CH4 + 2 O2 --> CO2 + 2 H20
Answer:
When a large, fissile atomic nucleus such as uranium-235 or plutonium-239 absorbs a neutron, it may undergo nuclear fission. The nucleus splits into two or more lighter nuclei, releasing kinetic energy, gamma radiation, and free neutrons.
Explanation:
the fire spreading is what represents the form of heat transferring from one atom to another within an object and direct contact
Answer: The coefficient must be 3.
Explanation:
According to the law of conservation of mass, mass can neither be created nor be destroyed. Thus the mass of products has to be equal to the mass of reactants. The number of atoms of each element has to be same on reactant and product side. Thus chemical equations are balanced.

The number of atoms of each element has to be same on both sides, thus the balanced chemical reaction will be:

Thus a coefficient of 3 should go in front of
to balance calcium (Ca).
