if the limestone is 98.20% pure and the iron ore contains 12.80% SiO2 by mass? (Note: SiO2 (s) + CaCO3 (s) ---gt; CaSiO3 (s) + CO2 (g) )(hint --- Calculate the number of moles in 1 Kg of iron ore, then use the number of moles of limestone to calculate how many kgs of limestone are needed for that 1 kg. )
1 kg iron ore contains 128 g SiO2 128 g SiO2 2.130 mole of SiO2 (128 / 60.09) 2.130 mole of SiO2 requires 2.130 mole of pure CaCO3 2.130 mole of CaCO3 213.2 g (2.130 x 100.09) since the limestone is 98.20% CaCO3, you need 217 g limestone or 0.217 kg (213.2g/.982217g)
i found out the best additive is BG oil additive. you might pay more for it but it works pretty good. you really should change the oil before putting it in though.
I use Lucas oil additive. My 99 F-150 has 240,000 miles on it and still runs like new.
Additives do not work and are only a temporary cover up to your real problem. See a mechanic.
