Solve all using two methods each 4. Calculate the mass of anhydrous Na2CO3 in 25.0 cm3 of the saturated solution at 30oC, if its solution at this temperature is 1.80 moldm-3 [Na = 23, C = 12, O = 16]

5.
What volume of a saturated solution of X at 0oC would yield 10.0 g of the dry salt, if the solubility of Y at 0oC is 5.0 moldm-3? [X=160]

a is the answer

explanation:

which statement about trans-fatty acids is false?

a. the conversion of cis-fatty acids to trans-fatty acids is inhibited by the presence of antioxidants.

hope this

question: ray weighs 100 kilograms, his wrestling partner, bobby, weighs 50 kilograms. if ray moves at 4 m s , how fast will bobby have to run at him to apply an equal amount of kinetic energy?

answer: 8 m/s he needs to run twice as fast to keep up so he has some work to do

explanation:   if the mass has units of kilograms and the velocity of meters per second, the kinetic energy has units of kilograms-meters squared per second squared.

i just calculated it all out, and not including weekends, and all the different days off. as of this school year (2018-2019) students are spending 2198 hours in school this year
