Question- Write the reaction of (a) strong acid, HNO3, with water, (b) the reaction of a week acid HCLO2 with water.
Write the complete solution in short and simple way
Explain How to determine this A sample of 2.0 moles of a metal reacts completely with excess oxygen to form 62.0 g of M2O. Explain what element is represented by the symbol M
Thermodynamics offers a way to interpret everyday occurrences. If you live in northern climates, one common experience is that during early winter, snow falls but then melts when it hits the ground. Both the formation and the melting happen sponta..
If 3 moles of NaCl are needed to produce 1 mole of AlCl3, how many grams of NaCl are needed to produce 200 grams of AlCl3? Show all of your work/calculations.
Write the equation(s) that describe the synthesis of (NH4)2PbCl6 starting from Pb(II) [i.e Pb(NO3)2]. Hint:There is a redox reaction in the first step, where the bleach (ClO^-) is the oxidising agent.
A bottle of wine contains 13.5% ethanol by volume. The density of ethanol (C2H5OH) is 0.789 g/cm3. Calculate the concentration of ethanol in wine in terms of mass percent and molality.
Sketch the experimental setup being sure to label the anode, cathode, direction of ion and electron flow, along with signs of each electrode.
pure liquid octane d 0.709 gml is used as the fuel in a test of a new automobile drive train. how much energy in kj is
A zero-order reaction has a constant rate of 3.50×10-4 M/rm s. If after 65.0 seconds the concentration has dropped to 1.00×10-2 M, what was the initial concentration?
The system then re-equilibrates. The appropriate chemical equation is PCl3(g)+Cl2(g) PCl5(g) Calculate the new partial pressures of PCl3, Cl2, and PCl5 after equilibrium is reestablished.
4 moles of nitrogen gas is placed inside a piston and cylinder device. The piston has a mass of 50 kg and an area of 0.05 m2. 100 kg of weights are placed on the piston. After coming to equilibrium the piston is locked into place.
If the measured cell potential is 0.95 V at 25 °C and the standard reduction potential of the Ag /Ag half-reaction couple is 0.80 V, calculate the hydrogen ion concentration in the anode compartment.
