First, find out how many grams are in one mole of CO2(the two oxygen atoms means you need to multiply oxygen’s amu by 2,then add whatever carbon’s amu is to that). Then divide 26 grams by that number and that will be your moles. There are only two significant figures, so round your answer correctly.
Answer:
2 P2 (1.2 atm =157 one. 8. A gas with a volume of 4.0 L
Explanation:
Answer:: Ionic solutions completely dissociate into ions. i.e. NaCl becomes Na+ and Cl-.
Molecular compound donot dissociate, they remain whole compounds. i.e. CH2O remains CH2O.
Explanation:
Answer:
2-methylbutane
Explanation:
First, you want to identify the largest number of sequential carbons. In this case, the parent chain is made up of 4 carbons. This makes the base name, butane.
Next, you want to identify any branches. There is a branch made up of 1 carbon, and these are referred to as a methyl group. The lowest possible carbon on the parent chain this branch is attached to is the second carbon.
When you put these factors together, you are left with the name: 2-methylbutane.
Answer:
Radiation, because the element of the heater comes in contact with air in the room. Convection, because energy is carried by waves and not matter. Radiation, because heat travels in a cyclical manner.
