What were Levels of CO2 in the cretaceous period?
The carbon dioxide (CO2) levels in the Cretaceous were 1,700 parts per million. That is 6 times the modern pre-industrial level (the amount of CO2 before the industrial revolution). The higher CO2 levels may have been partially responsible for the warm average temperature during the Cretaceous (4 C [7.6 F] above modern temperature).
What mass of CO2 is produced in the reaction of 4 moles of CH4 in excess O2?
Mass of 4 mole CO2 , this is 4 * (12 + 2*16) = 176 grams
What is the pH of water when you just put CO2 in the water?
4

What environmental characteristics increase the rate of photosynthesis?
Factors affecting the rate of photosynthesis are 1) Light intensity: - the brightness which increases the rate of photosynthesis if increased 2) Light quality: - the color of the light (chlorophyll absorbs red and blue and reflects green, orange, and yellow so red and blue are preferable) 3) CO2 concentration: - the more CO2 the more photosynthesis will occur. 4) chlorophyll availability: - the more chlorophyll the more photosynthesis will occur. 5) water: - INDIRECTLY as if there is little water the plant will stop transpiration by closing the stomata keeping the water inside, but not allowing gaseous diffusion.
Does human activity produce green house gases?
Yes, the most common cause is the burning of fossils fuels such as coal oil and gass and is said to account for 3/4 of all CO2 emissions, deforestation also affects CO2 levels
In this equation 2mno2 plus 2k2co3 plus o2--2kmno4 plus CO2 what atom increases in oxidation number?
Mn increase in oxidation number from +4 to +7.
What are the 4 levels of the forest?

Is carbon's charge -4 or 4?
It can be either. In CO2 it is +4, in a carbide it is -4.
What mass of CO2 is produced in the reaction of 4 moles of CH4 in excess O2?
Mass of 4 mole CO2 , this is 4 * (12 + 2*16) = 176 grams
What is the oxidation number of carbon in carbon dioxide?
In methane (CH4), carbon is in the 4- oxidation state.
What is the percent increase of 200 to 208?
As 8 is 4% of 200, it would be a 4% increase.
How many CO2 is found in hemoglobin?
At the end of each protein chain in a hemoglobin (4) there is a amine group for the CO2 to bind to...therefore it can hold 4.
