Answer:
yes
Explanation:
Although plants use photosynthesis to produce glucose, they use cellular respiration to release energy from the glucose.
Rutherford's gold foil experiment proved that there was a small, dense, positively charged nucleus at the center, which contained most of the mass of the atom. Which contained electrons orbiting the nucleus.
Answer:
Filtration
Explanation:
Metal carbonate is insoluble, it is possible to filter off the unreacted substances leaving the desired salt solution
The mass of lime that can be produced from 4.510 Kg of limestone is calculated as below
calculate the moles of CaCO3 used
that is moles =mass/molar mass
convert Kg to g = 4.510 x1000 =4510g
= 4510 / 100 =45.10 moles
CaCO3 = CaO +O2
by use of mole ratio between CaCO3 to CaO (1:1) the moles of CaO is also= 45.10 moles
mass of CaO = moles x molar mass
45.10 x56 = 2525.6 g of CaO
The mass of Hydrogen is 2 g/mol
The mass of Helium is 4 g/mol
