a student mixed two clear liquids together in a beaker and a solid precipitate formed. his data is shown below:
liquid reactant a: 10 g
liquid reactant b: 17 g
beaker+solid product: 32 g
what is the mass of the beaker?
a. 5 g
b. 10 g
c. 15 g
d. 17 g
e. 32 g

This might be right. Im not quite sure. This is what my 5th grade science teacher told me. 'Look at the 2 LR's and add them together. Then look at the total amount which is 32. When you add the 2 LR's you get 17. So subtract 17 from 32 and you get 15. So: C:15 is your answer." (LR's stands for liquid reactants)

10+17=17

Total amount is 32

32-17=15

15 is you mass

Hope this Helps

it is to be noted that an alpha particle is an helium nucleus. so it contains 2 protons 2 neutrons and has a mass number of 4. when alpha decay particles are ejected from the nucleus it gets transformed into an atom which has atomic number less than 2 and a mass number less than 4.

an equation that could represent alpha decay is radium 226 decay of alpha particle forms radon 222.
