Answer:
Hydrogen gas is highly combustible, and leakage can lead to a catastrophic explosion. The concentration of hydrogen gas in the furnace is held constant at 6.022 x 1023 atoms/m3 and is effectively 0 outside the furnace. Calculate the mass flow rate (mg/hr) of hydrogen from the furnace if the diffusivity of hydrogen through the glass is 2 x 10-5 m2 /s. You may assume steady state behavior and constant diffusivity. You may assume that diffusion only occurs through the glass. The molar mass of hydrogen can be taken as 2 g/mol

Answer:
Species
Explanation:
Species is the group of organisms able to interbreed and produce fertile offspring.
Let's break down each word in the question:
"Organisms" means living thing. It can be a plant or animal like we usually think of, but it also includes the really small single-celled living things like some bacteria.
"Interbreed" means to mate with each other.
"Fertile" means that the living thing can also have babies.
"Offspring" means the children that are born.
"Fertile offspring" means that the children that are made must be able to have babies of their own. For example, if a frog and a bird could interbreed, they might produce offspring (children). But, if those frog-birds cannot also have children, then frog-bird is not a species.
