January, 2015 Chemistry Regents: Questions, Answers & “Ways”

chem regents 2014 answers

What occurs at one of the electrodes in both an electrolytic cell and a voltaic cell? Correct Hydrogen atoms are added to the ethene molecule at the site of the carbon-carbon double bond to form a single molecule. Elements to the right are metals. An unsaturated reactant becomes a saturated product. Incorrect Hydrogen atoms are added to the ethene molecule at the site of the carbon-carbon double bond to form a single molecule. Incorrect The number of each kind of atom is the same in both, but their structures are not the same. Their molecular formulas are the same but their structural arrangement of atoms is different. Correct There is a greater electronegativity difference in a C-O bond than in a C-H bond.

Look for the zig-zag line. The C-O bond is more polar because the electronegativity difference for a C-O bond is 0. They have the same atomic number but different mass numbers. Two reactant combine to form a single product. The malleability of gold is due to the I radioactive decay, mode of the isotope An-19S 2 proton-to-neutron ratio in an atom of gold 3 nature of the bonds between gold atoms 4 reactively of gold atoms 3 malleability is due to metal atom being able to shift position and still be bonded 9 Which term represents the attraction one atom has for the electrons in a bond from another atom? Correct Properties of Ideal gases.

They have the same atomic number but different mass numbers. Use Reference table S to find the symbol of the element sulfur. The C-O bond is more polar because the electronegativity difference for a C-O bond is 0. The reaction is hydrogenation reaction, which is a type of addition reaction. Hint I-127 atoms and I-131 atoms have the same number of protons, but different numbers of neutrons. Look for the zig-zag line. Both cases are a mixture — but the proportion of salt in the water is different, therefore it is a mixture but the proportions of its components can vary from one sample to the next.

Both cases are a mixture — but the proportion of salt in the water is different, therefore it is a mixture but the proportions of its components can vary from one sample to the next. The C-H bond has a smaller difference. Hint Hydrogen atoms are added to the ethene molecule at the site of the carbon-carbon double bond to form a single molecule. The reaction is hydrogenation reaction, which is a type of addition reaction. Elements to the left are Non-Metals. Both have 53 p, but I-127 has 74 n while I-131 has 78 n. Po is noted as being a metalloids in some books.

Kinetics and Equilibrium 0% Correct Use the Periodic Table. An unsaturated reactant becomes a saturated product. Two reactant combine to form a single product. Po is noted as being a metalloids in some books. The C-H bond has a smaller difference. Their molecular formulas are the same but their structural arrangement of atoms is different.

Since the electron is still part of the atom and has not been removed it is still an atom and not an ion. Elements to the left are Non-Metals. Both have 53 p, but I-127 has 74 n while I-131 has 78 n. The C-O bond is more polar because the electronegativity difference for a C-O bond is 0. .
