Answer:
In a nonpolar covalent bond, the atoms share electrons equally with one another.
Explanation:
Nonpolar covalent bonds are a type of bond that occurs when two atoms share a pair of electrons with each other. These shared electrons glue two or more atoms together to form a molecule.
Answer:
a) Can be cut into tiny pieces - Physical Change
b) Fizzling occurs when placed water -Chemical Change
c) Light is emitted when burned -Chemical Change
d) Turns to ash -Chemical Change
Explanation:
The
mass of an atom comes from the protons and neutrons that are found in the
nucleus. The number of protons is the atomic number of an element. To find the
number of neutrons, subtract the atomic number from the mass of an atom. The number of atoms of an
individual element be determined by using a chemical formula and adding all of
the subscripts together after the reaction is complete. The key in the balancing of chemical reaction is to make sure that you got the
exact chemical formula of the substance that is reacting and the yielded
product. After getting the formula, identify first the hardest element/atom to
be balanced such as Na, Zn, Cl, C, O, etc. Then proceed to the easier ones such
as O, H. Make sure to note the atoms present in the molecule of the substance.
Answer:
The answer to your question is the letter C) Synthesis.
Explanation:
Data
H₂ and O₂ produces water
Balanced chemical reaction
2H₂ + O₂ ⇒ 2H₂O
Definition of the kinds of reactions
A) double-displacement is a reaction where the cations and anions of the reactants are interchanged.
B) endothermic is the chemical reaction that needs a supply of energy to proceed.
C) synthesis is the chemical reaction where two reactants combine to form only a product.
D) combustion is the chemical reaction where a compound with carbon reacts with oxygen to form carbon dioxide and water.
Conclusion
From the information given we conclude that the reaction between hydrogen and oxygen is a synthesis reaction.
