Answer:
150g
Explanation:
Assuming they are ideal gases at the same temperature and pressure, equal moles of gasses have equal volume. IN this case, if we have 10g of hydrogen gas, that is 5 moles of H2 gas. That means 5 moles og NO2 will occupy the same volume which is 5*(14.0 + 16.0*2) = 230 g
A is is a double replacement reaction (Cations and anions switch)
B is a Decomposition reaction (Breaks down into simpler substances)
C is a Synthesis or Combination reaction (both are the same thing)
D is a Combustion reaction (compound made of carbon and hydrogen reacts with oxygen)
and E is a Single replacement reaction (Cations trade)
Hope this helps! :)
Answer: I believe this statement is true.
Explanation: Energy decreases as it moves up trophic levels because energy is lost as metabolic heat when the organisms from one trophic level are consumed by organisms from the next level. Sorry if this is wrong, it is just what i believe.
Answer:
(i) 5-day BOD of the waste is 120 mg/l.
(ii) The ultimate carbonaceous BOD (Lo) is 20 mg/l.
Explanation:
The dilution factor D is 0.05.
The initial DO is 8.0 mg/L and the DO after 5 days is 2.0 mg/L.
The BOD of the waste for an unseeded mixture is

The ultimate carbonaceous BOD (Lo) can be calculated as

Answer s=d/t
Explanation:
That means speed equals distance divided by time. To solve for time use formula for time: t=d/s
