Humans can reduce the number of landfills by starting to only use reusable products. Instead of buying 3 milk cartons a month we need to create a system where we reuse everything. We could also recycle paper, make a compost in our houses. There are multiple ways to fix the issue of landfills.
Answer:
D
Explanation:
it is neon because neon has a higher atomic number so it would have more protons and neutrons and electrons in one atom thus having more particles in one mole
Answer:
That makes Dimagnesium phosphate
The mass of bismuth carbonate that decomposed is 0.445 g
calculation
write the equation for reaction
that is Bi2(CO3)3 → Bi2O3 +3 CO2
find the moles of of CO2 formed
At STP 1 mole of a gas = 22.4 L
what about 50 Ml
convert the Ml to Liters = 50/1000= 0.05 L
moles of CO2 formed is therefore= 1 mole x 0.05 L/22.4 l =2.232 x10^-3 moles
by use of reacting ratio between Bi(CO3)3 to CO2 which is 1:3 the moles of Bi(CO3)3 is = 2.232 x10^-3 x1/3= 0.744 x10^-4 moles of Bi(CO3)3
mass of Bi(CO3)3 = molar mass x number of moles
mass= 0.744 x10^-4 moles x 597.99 g/mol = 0.445 grams
