Answer:
Explanation:
Mass of one tablet = 20 mg
Mass of two tablets =
Percent that is soluble in water = 40%
Mass of tablet that is soluble in water =
So, mass of solute is
Density of water = 1 kg/L
Volume of water = 1 L
So, mass of 1 L of water is
PPM is given by
Hence, the concentration of iodine in the treated water .
Answer: nucleus
Explanation: the bigger the nucleus there more reactive the atom is
The final temperature = 36 °C
<h3>Further explanation</h3>
The balanced combustion reaction for C₆H₆
2C₆H₆(l)+15O₂(g)⇒ 12CO₂(g)+6H₂O(l) +6542 kJ
MW C₆H₆ : 78.11 g/mol
mol C₆H₆ :
Heat released for 2 mol C₆H₆ =6542 kJ, so for 1 mol
Heat transferred to water :
Q=m.c.ΔT
<span>A SI base unit is the single and direct measurement unit for a physical entity. E.g. For mass it is kg, for time it is sec, A derived unit is determined by a physical equation with the base units, like for velocity equals distance divided by time, in SI units: unit of v (velocity)= m (meter) divided by sec (seconds).
