Balance the Following Equation: __H2SO4 + __NaOH ---> __Na2SO4 + __H2O

Balancing chemical equations requires the same quantity of products as reactancts. There are two atoms of H on the left and therefore two on the left; one SO4 on the left thus one on the right; however while...

Give the IUPAC name of CH3CH2CH2CH2CH(OH)CN and describe why the formation of this molecule creates 2 enantiomers.

The IUPAC name of CH 3 CH 2 CH 2 CH 2 CH(OH)CN is 2-Hydroxyhexanenitrile as its carbon chain is 6 carbons long (Hex). The nitrile group takes naming priority over the alcohol group so goes at the end of the ...

An amino acid contains 52.2% carbon, 9.3% hydrogen, 8.7% nitrogen and 29.8% oxygen by mass and has a relative molecular mass of 161 g/mol. What is its molecular formula? What functional groups must it have?

In 100g of compound, the amount of each element is given by: C: n = 52.2/12 = 4.35 H: n = 9.3/1 = 9.3 N: n = 8.7/14 = 0.621... O: n = 29.8/16 = 1.8625 Dividing through by the smallest amount (0.621) gives: C...

explain ionic bonding in a giant ionic lattice?

Bonding is about the movement of electrons-electrons are NEGATIVELY charged-the electrons move to allow atoms to become more STABLE by having a full outer shell of electrons-The periodic table is useful to l...
