Answer:
The cell cycle is a four-stage process in which the cell increases in size (gap 1, or G1, stage), copies its DNA (synthesis, or S, stage), prepares to divide (gap 2, or G2, stage), and divides (mitosis, or M, stage). The stages G1, S, and G2 make up interphase, which accounts for the span between cell divisions
When copper (ii) oxide is heated in presence of hydrogen gas it produces copper metal and water vapor.
that is
CuO + H2 = Cu + H2O
The moles of copper metal produced is calculated as below
find the moles of CUO used
moles = mass/molar mass
=5.6/79.5 =0.07 moles
by use of mole ratio between CUO:Cu which is 1:1 the moles of Cu is also
=0.007 moles of Cu
