Propose a reasonable synthetic strategy for the synthesis of trans-6-methyl-3-heptene from 4-methyl-1-pentyne.
Solar furnaces are designed to focus sunlight (say, with a parabolic mirror ) onto a relatively small area. given that the surface temperature of the sun is about 600K.
Consider the balanced chemical reaction shown: 4PH^3 (g) + 8O^2 (g) ---> 6H^2O (l) + 1P^4O^10 (s) In a certain experiment, 8.92g of PH^3 reacts with 9.60g of O^2(g)
an acetic acid solution of 2.87 pH is titrated with 1.5 mL of bromocresol green. When the color changes to light green, the pH is 3.95. The final color of the solution is dark blue.
a solution is prepared by adding 40.3 g of Mg(NO3)2 to 127 g of water. Calculate the mole fraction and molality of magnesium nitrate in this solution
