- Question #e395e - Socratic
When decaying by alpha emission a nucleus drops by 4 in mass number and 2 in atomic number and emits a helium nucleus (alpha particle) which has mass number 4 and atomic number 2 194 81 T l → 190 79 Au + 4 2α Notice that the total mass number, and total charge (here only indicated by the atomic numbers ) remains unchanged, just moved around If the question meant another isotope, just

- How do you simplify t^ { \\frac { 13} { 5} } \\cdot t ^ { \\frac { 11 . . .
t^ (38 7) t^ (15 5)*t^ (11 7) =>t^ (15 5+11 7) =>t^ (135 35+55 35) =>t^ (190 35) =>t^ (38 7)
- Question #9c6af - Socratic
"3 2 mol kg"^(-1) In order to be able to calculate the molality of the solution, you need to know the number of moles of solute present for every "1 kg" = 10^3 "g" of solvent In your case, you know that this solution is "16% m m" urea, which implies that you get "16 g" of urea, the solute, for every "100 g" of solution If you take a "100-g" sample of this solution, you can say that it
- Question #bae16 - Socratic
See a solution process below: The formula for the sales price of an item is: s = p - (p * d) Where: s is the sales price: what we will solve for twice in this problem p is the original price: £280 in the first part of this problem d is the discount rate: 15% in the first part of this problem "Percent" or "%" means "out of 100" or "per 100", Therefore 15% can be written as 15 100
- What is the mass of 211mL of a liquid that has a density of . . . - Socratic
Approx 190*g By definition, rho, is given by the quotient rho_"density"="mass" "volume", and thus has units of g*mL^-1-=g*cm^-3 And so we simply rearrange
