Answer:
Soil
Explanation:
Plants(a.k.a. Producers) obtain nitrogen(N) from the soil by absorption through their roots.
Answer:48kg of SiO2, 0.5kg of Al2O3, and 1.5kg of B2O3
Will be the final product
Explanation:
I) 96wt% of SiO2 will amount to 96/100*50 = 0.96*50=48kg of SiO2
ii) 1wt% of Al2O3 will amount to 1/100*50 = 0.01*50=0.5kg of Al2O3
III) 3wt% of B2O3 will amount to 3/100*50 = 0.03*50=1.5kg of B2O3..
The overall product form 48+ 0.5+1.5= 50kg
Iscotopes are usually stbolized in the following way:
X represents the chemical symbol
A rep Z represents the atomic number.
