Which of the following statements about the reaction of one mole of methane at STP is NOT correct? CH4(g) + 2O2(g) CO2(g)+ 2H2O(g) O In a 1:1 ratio of CH4(g) and O2(e), methane would be the limiting reagent. O Guy Lussac's Law of combining volumes suggests a whole number ratio for products and reactants of 1 22.4 liters of methane would react stoichiometrically with 44.8 liters of oxygen If CH4(e) and are O2(g) initially present in a 1:2 ratio, there will be no change in the overall volume of the system after reaction.​

Ineed to find the answer of this question because i dont understand it

To calculate percent by mass, use the equation below: calculate the percent by mass of each element. %n = % %h = % %o = %

(04.05 hc) analyze the given diagram of the carbon cycle below. an image of carbon cycle is shown. the sun, a cloud, two trees, one on the left and the other on the right, an animal, lake, and a factory are shown in the image. an arrow is shown from the sun towards the left tree marked a. the sun is marked b. there is an arrow from the air above the clouds, marked c, towards the left tree. an arrow from a location close to the ground marked d points towards dead organisms, which is a label under the animal. an arrow marked e points from the right tree straight up to the clouds. an arrow marked f points from the animal straight up to the clouds. an arrow marked g points from the factory towards the air above the clouds, c. there is an arrow pointing from the air to the lake labeled carbonates in water, an arrow pointing down from dead organisms to fossils and fossil fuels, and an arrow from fossils to the factory. part 1: which compound does c represent? part 2: name a process that could release this compound into the air. part 3: explain how the elements that form it are conserved during the carbon cycle. use complete sentences to explain your answer.
