Q #4 please help if you are sure

Chemistry
1 answer:
Mashutka [201]3 years ago
8 0

(Answer) (d) Chemical reaction rates vary with the conditions of the reaction, but nuclear decay rates do not.

Rate of a chemical reaction refers to rate of formation of products from reactions during a chemical reaction. The rates of chemical reactions depend on various factors such as temperature, pressure, concentration of reactants, presence of catalyst etc. For this reason, chemical reaction rates vary with the conditions of the reaction.

Nuclear decay rate refers to the constant ratio of the number of atoms of radioactive nucleus that decay during a certain interval of time to the total number of radioactive atoms at the beginning of the time interval. Nuclear decay rates are constant and do not vary with the conditions of the reaction.

How does the comic strip define a polar molecule
zmey [24]

The answer is: A molecule with a difference in electrical charge between two ends.

Electronegativity (χ) is a property that describes the tendency of an atom to attract a shared pair of electrons.

Atoms with higher electronegativity attracts more electrons towards it, electrons are closer to that atom.

For example fluorine has electronegativity approximately χ = 4 and oxygen χ = 3,5, fluorine attracts electron and he has negative charge and oxygen has positive charge.

A slice of Swiss cheese contains 48 mg of sodium
Nookie1986 [14]

Answer: grams=0.048g, ounces=0.0017oz, 0.00011lb

Explanation:

Stoichiometry

48 mg x  1 g

          ÷  1000 mg  = 0.048 g

48 mg x  1 g            x 16 oz        

          ÷ 1000 mg  ÷ 453.6 g     = 0.0017 oz

48 mg x  1 g            x 1 lb        

          ÷ 1000 mg  ÷ 453.6 g     = 0.00011 lb

Nucleotide bases bonded to a sugar phosphate backbone make up _____.
Alchen [17]
Nucleotide bases bonded to a sugar phosphate backbone make up nucleic acids such as DNA (deoxyribonucleic acid) and RNA (<span>ribonucleic acid)</span>. Nucleotides have three major parts: sugars, phosphates, and a nitrogenous base. DNA uses four nitrogenous bases: Adenine, Guanine, Cytosine, and Thymine. RNA uses the same bases except for Thymine, which is replaced by Uracil.
