Answer:
9
Explanation:
To balance the equation, we need to supply the number of missing coefficients.
There are 2 moles of aluminium on the right hand side, so automatically we need to multiply the number of moles of aluminium by 2 on the left hand side.
There are 3 sulphate ions on the right hand side so we need to multiply the number on the left by 3.
And lastly since we have 6 hydrogen molecules on the left hand side now, we need to multiply the hydrogen on the right hand side by 3 to give 6
The set of coefficients = 2 3 1 3
Adding all thus yields 9
The<span> pros of using GMO are that
they result in higher yields than natural food crops hence able to feed a growing
human population on earth. They are also able to withstand crop diseases and
pests hence improved yields. </span>
The cons of transgenic
plants contribute to antibiotic resistance especially due to the use of antibiotic
resistance genes in recombination genes. Another is the environmental impact.
GMO may result in uncontrolled gene transfer to natural crops in the environment
hence created challenges such as super-weeds.
Answer is distillation.
the less polar liquid will distill faster at lower temperature compared to the polar liquid
Answer:
<u><em>Explain both aldehydes and ketones, the geometry around the carbon atom in the carbonyl group is trigon planar; the carbon atom exhibits sp2 hybridization. Two of the sp2 orbitals on the carbon atom in the carbonyl group are used to form σ bonds to the other carbon or hydrogen atoms in a molecule. The remaining sp2 hybrid orbital forms a σ bond to the oxygen atom. The hybridized p orbital on the carbon atom in the carbonyl group overlaps a p orbital on the oxygen atom to form the π bond in the double bond.ation .</em></u>
