The answer is TRUE.
Energy is an extensive property, which means that it is in proportion to the amount of matter: more mass, more energy.
You can measure, for example, the internal energy per mol or per gram of several compounds or elements. then if you want to know the total internal energy of the system you have to multiply by the number of moles or grams, depending on the unit of the internal energy that you use.
Convert 0.47g 2-naphthol to mols. mol = g/molar mass.
Using the coefficients in the balanced equation, convert mols 2-naphthol to mols 2-butoxynaphthalene then you have to Convert mol 2-butoxynaphthalene to grams. g = mols x molar mass. This is the theoretical yield.
I would be neutral because h20 has a impact on water
Answer:
Salt.
Explanation:
Salt=NaCl
Ionic bonds are made when the two elements are from different sides of the periodic table. On the left, we have our metals. On the right, we have our nonmetals. Sodium is a metal and Chlorine is a gas. Water, sugar, and carbon dioxide are covalent bonds because all the elements are from the right side of the periodic table. Hydrogen is a nonmetal too.
The molar mass of this compound is 0.004 m/g
Firstly, molar mass is moles/grams so we need to solve for the number of moles and we were already given the grams (205 g).
So to solve for moles we were given 205 g, 20.0 L, 273 K and 1.00 atm. Knowing these numbers we can plug them into the ideal gas law, PV=nRT
where P is pressure, V is volume, n is number of moles, R is the gas constant (in this case it is 0.08206) and T is the temperature.
Next, we use moles and grams to solve for molar mass:
