15) Potential Catalyst Effects On Reaction Rate Reactant Oxygen produced H2O2 2 +0.1M FeCl3 5 +0.1M NaCl 0 +0.1M Fe(NO3)2 4 +0.1M KNO3 0 10 ml of a 3% hydrogen peroxide solution is added to five test tubes. As the hydrogen peroxide decomposes to produce oxygen gas, the rate of oxygen production is rated on a scale of 0 - 5, 0 meaning "no oxygen" and 5 meaning "fast". To the other four test tubes of hydrogen peroxide, five drops of additional solutions are added. The solutions are indicated in the data table as well as the rate of oxygen production for each. Based on the data, what is the MOST appropriate conclusion for this experiment? A) Iron compounds are always used as catalysts. B) Reaction rate is always increased by iron compounds. C) Increasing the temperature increases the rate of decomposition. D) Iron compounds are a catalyst for the decomposition of hydrogen peroxide.

the correct answer is - d. china has a large and growing population.

the fact that china has a large (the biggest) population, and it is still growing, doesn't hinder the agriculture production in the country. in fact, it can for increased production in the agriculture, since there's more labor force, as well the sheer mass of people produces lots of scientists that come up with new inventions as to how to improve this sector. nice example is the inner mongolia region in china, in general dominated by the gobi desert, but few scientist came up with a nice idea as to how to make the region productive by using plants that are very resistant to droughts, so lots of people have been employed, and the region is becoming greener and greener each year, and the production of food in this region is also increasing.

blue is scattered more than other colors because it travels as shorter, smaller waves. this is why we see a blue sky most of the time.
