A chemical with a toxic level of 0.03 ppm is more toxic because heavy metals with high density are toxic to organisms at low concentrations.
In other words, it only took 0.03 ppm of the chemical to kill an organism, while the other chemical would have to take up to 3 ppm in order to kill the same organism. Which one is more toxic?
What else can I help you with?
Toxic chemicals in drinking water usually are reported and a safety level specified in units of parts per million ppm by mass Show how to calculate the molar concentration of arsenic in a water sam?
1 ppm means one gram of arsenic per 1,000,000 grams of water 1,000,000 grams of water is 1,000 litres = 1,000 dm^3 (one gram = one ml) assuming we have this quantity of solution: moles arsenic = mass/Mr = 1/74.9 = 0.0133511348 moles but this is for 1,000 dm^3, so for 1 dm^3 we have 1000th of this amount, which is 1.335113485 x 10^-5 moles So the molar concentration is 1.34 x 10^-5 mol.dm^-3
Does capacitance increase when the temperature increases?
It depends on what the capacitance is. 1. Capacitors may show a positive temperature coefficient, 2. "N750" ceramic capacitors have a negative coefficient of -750 parts per million per degree (ppm/º), 3. "NPO" ceramic types have a substantially zero ppm/º. Check the Wikipedia entry for "ceramic capacitor" for more info.
