What initially forms as pale blue and pale green precipitate when nh3 is added to cuh2o6?

andre [41]

The chemical equation that shows the reaction between nh3 and cuh206 is detailed as: [Cu(H2O)6]2+ (aq) + 2NH3(aq). —> [Cu(OH)2(H2O)4](s) + 2NH4 + (aq). the blue precipitate is Cu(OH)2(H2O)4 in which the blue color is caused by the Cu present in the solid.

A scientist put red blood cells in water that contained salt. Over time, the red blood cells burst. What is most likely true?

Tamiku [17]

Answer: There was a lower concentration of salt in the water than in the cells.

Explanation:

Osmosis is a process in which the solvent flow from a solution of low concentration to a solution of high concentration through a semi-permeable membrane.

When the red blood cells are put in water that contained salt and the red blood cells burst after some time.

This means the solvent has moved from outside to inside the cell and this is possible only when the concentration of solute is high inside the cell than outside. That means the solution has low concentration of solute as compared to the cell and was a hypotonic solution.

Calculate the mass of 0.00456 moles of (NH4)2SO4

Anna [14]

To find the mass you need to find the weight of a mol of the molecules by adding up the atomic mass.

N = 14.007 g/mol
H = 1.008 g/mol
S = 32.065 g/mol
O = 16 g/mol

2(14.007) + 8(1.008) + 32.065 + 4(16) = 132.143 g/mol

Now you know how much an entire mol weight you multiply it by how much you actually have

0.00456 * 132.143 = 0.603 g
