Question was raised about the mass produced when a log burns The products have a greater mass than the original log that was burned Where did the extra mass come from?
A log mainly consists of carbon and hydrogen. It has a few other elements. Carbon has an atomic weight of 12. Hydrogen has an atomic weight of 1. Oxygen comes from the air. It has an atomic weight of 16. If you take one carbon atom from the log and you take 2 oxygen atoms from the air, you get carbon dioxide. Carbon dioxide will have a weight of 12 + 16 + 16 = 44. Water is two hydrogen atoms and one oxygen. Lets see 1 + 1 + 16 = 18. Now if we take a hydrocarbon with the equivalent of 12 water molecules attached to 12 carbon atoms the water molecules will cancel each other out. We only need to work with the carbon. We start with 144 as the weight of the carbon. When we add the weight of the oxygen from the air we end up with 528. That is what we get when we add oxygen from the atmosphere.

Why the combined mass of CO2 and H2O produced in the combustion analysis of methane greater than mass of the methane sample being analysed?
The mass of reactants is equal to the mass of products.
Are sperm produced in greater or smaller numbers than egg cells?
greater
What if kc expression is greater than 1 in chemistry?
If the Kc expression is greater than 1 in chemistry, it means that the concentration of products in the equilibrium mixture is higher than the concentration of reactants. This suggests that the reaction favors the formation of products at equilibrium.
Where in the universe are heavy elements with masses greater that that of helium being produced today?

What accurately describes a shortage?

What is the meaning of economies of product differences?
The meaning of economies of product differences... The greater the difference in products produced by two economies the greater the economic efficiency to be obtained from trade between the two as per the theory of comparative advantage.

What is the type of percent when the final amount is greater than the original amount?
Greater than 100 if the original amount is positive. Less than 100 if the original amount s negative.
How modeling partial products can be used to find the products of greater numbers?
It is easier to multiply
How is carbon monoxide made in car?
Carbon Monoxide is a by-product of combustion of petroleum (Gasoline) When gasoline burns (Because of the ignition that happens within the engine) it products carbon monoxide (Chemical Formula "CO"). The greater the engine capacity and power/speed, the greater is the amount of gasoline that gets burnt and greater is the amount of carbon monoxide produced
What determines a price of a good service?
The price and quantity are generally determined by the demand for the products, e.g the desire by consumers to purchase them. Generally, the greater the demand, the higher the price, and the greater the quantity that will be produced for sale.
How is technology involved in agricultural Revolution?
Advances in transportation like trains and steamboats let people export goods easily, and advances in manufacturing like the cotton gin allowed a greater volume of products to be produced.
An energy diagram shows the reactants having greater energy than the products illustrates what?
This shows that the reaction is endothermic because energy is absorbed in the reaction and not produced.
What if kc expression is greater than 1 in chemistry?
If the Kc expression is greater than 1 in chemistry, it means that the concentration of products in the equilibrium mixture is higher than the concentration of reactants. This suggests that the reaction favors the formation of products at equilibrium.
