Social cost, Economic costs and Environmental Costs could be reduced by using Renewable energy sources like Hydro Power, Solar Power, Wind Power, Biomass and Geothermal plants. They can provide sustainable energy services since they are available all of the time. They known to have less impacts on various aspects especially in the environmental aspect comparing it to nonrenewable resources like fossil fuel based power plants.
Answer:
It's obviously true
Explanation:
As we have evolved over the years we have become more advanced
Empirical formula is calculated as follows
calculate the moles of each element, that is % composition/ molar mass
molar masses ( Si= 28.09g/mol , Cl= 35.5 g/mol, I=126.9 g/mol)
moles of silicon = 7.962/28.09g/mol= 0.283 moles
moles of chlorine = 20.10 / 35.5g/mol = 0.566 moles
moles of iodine= 71.94 / 126.9 g/mol= 0.567 moles
divide each mole with smallest mole (0.283)
that is silicon = 0.283/0.283= 1 mole
chlorine = 0.566/0.283= 2 mole
Iodine= o.567/0.283= 2 moles
empirical formula is therefore= SiCl2I2
NH3 has a Molar mass of 17g
3.47 * M(NH3) = 58.99g of NH3 in the cleaning agent
