Answer:
Plants, algae, and a group of bacteria called cyanobacteria are the only organisms capable of performing photosynthesis
Explanation:
mass = moles * molar mass
molar mass of carbon dioxide (CO2) = 12+32 = 44
= 19.5* 44 = 858
proof
moles = mass /molar mass
= 858/44 = 19.5 moles
Answer:
Oh come on. Look at all - then look at A.
Explanation:
The noble gases don't react because they have their full orbital. They have 8 valence electrons, meaning that they are happy and stable. They dont need any more electrons, which means that they dont need to bond. That makes them un- reactive.
It's not chemical because it would have to react to something to change so it is physical change because it is the same thing but it just smells I hope this helped
