Ok so 40 percent of 3000 grams which is 3 kg is 1200 grams
So you would need 1.2kg or 1200 grams to make a 40% solution
The sun's gravity pulls the planet toward the sun, which changes the straight line of direction into a curve. This keeps the planet moving in an orbit around the sun. Because of the sun's gravitational pull, all the planets in our solar system orbit around it.
Answer:
CH2FCOOH > CH2ClCOOH > CH2BrCOOH > CH3COOH
Explanation:
CH2FCOOH > CH2ClCOOH > CH2BrCOOH > CH3COOH
More electronegative atom of halogen is , stronger acid will be.
Answer: E
Explanation:
The lattice energy is the energy change when one mole of a crystal is formed from its components ions in its gaseous sate
Therefore lattice energy = heat of Sublimation+ ionization energy +electron affinity-(heat of formation)
Therefore lattice Energy = 109 +495 -328 +570.
Lattice energy = --923kjmol-1
