Ethane, C2H6, burns in oxygen as follows. C2H6 + O2  CO2 + H2O
What mass of carbon dioxide is produced if 10.2 g of ethane and 44.6 g of oxygen are mixed and ignited? ( Ans = 29.9 g of carbon dioxide check 29 or 20)

Melting and boiling are endothermic processes. this means that these processes absorb energy from their surroundings in order to occur. use this information and the data you collected in the phase change gizmo to describe what happens to the temperature of water when you boil it, then explain why this result occurs.

Three alkali metals in group 1 are a. calcium, strontium, barium b. boron, aluminum, gallium c. sodium, potassium, rubidium d. fluorine, iodine, chlorine

How does the presence of oxygen affect the chemical pathways used to extract energy from glucose?
