What else can I help you with?
Which of the following is an example of an acid-base ReactionA. HCl + NaHCO3 ---> NaCl + CO2 + H2OB. O2 + 2PBr3 ---> 2POBr3C. 4Fe + 3O2 ---> 2Fe2O3D. Zn + 2HCl ---> ZnCl2 + H2?
Whoops, that came out incorrectly. Let me try to do it again... Which of the following is an example of an acid-base Reaction? A. HCl + NaHCO3 ---> NaCl + CO2 + H2O B. O2 + 2PBr3 ---> 2POBr3 C. 4Fe + 3O2 ---> 2Fe2O3 D. Zn + 2HCl ---> ZnCl2 + H2
What is the chemical equation of displacement reaction?
For example a single displacement reaction is:2 Na + 2 HCl = 2 NaCl + H2
What is used to represent chemical substances such as compounds?
Not all chemical formulas represent a compound. Chemical formulas that contain two or more elements represent a compound. Chemical formulas can also represent diatomic molecules, such as H2 or O2. Sulfur is represented by the formula S8.
What do the chemical formulas Cl2 O2 and H2 mean?
Cl2 represents a molecule of chlorine gas, O2 represents a molecule of oxygen gas, and H2 represents a molecule of hydrogen gas. These chemical formulas indicate the number and type of atoms present in each molecule.
Which chemical symbol is used to represent gas helium?
The symbol for hydrogen gas is H2
What is the formula for sodium chloride plus H2?
NaCl + H2.
What reactants would give sodium chloride plus hydrogen?
Sodium with HCl gives NaCl and H2 2Na + 2HCl -> 2NaCl + H2

What is the difference between sodium chloride and water?
Sodium chloride is NaCl. Water is H2O.
What happens when you add sodium with hydrochloric acid?
you get NaCl, H2, and a great deal of energy
Below is the unbalanced equation for this process balance the equation nacl plus H2O cl2 plus naoh plus h2?
HCl + NaOH = H2O + NaCl is already balanced.
Hydrogen and helium formulas?
Hydrogen is H2. Helium is He.
What happens to sodium when added to hydrochloric acid?
NaCl salt is formed and H2 gas is given off
What is some examples of terms and symbols in a chemical equation?
Examples: NaCl, H2, =, +, ----------------->, ↔, (s), etc.
Do and do not represent a compound o2 n2o co2 h2 naci?
O2: This compound represents oxygen gas. N2O: This compound represents nitrous oxide, a gas used as an anesthetic. CO2: This compound represents carbon dioxide gas. H2: This compound represents hydrogen gas. NaCl: This compound represents sodium chloride or table salt.
What is the reactants betwen sodium metal and hydrochloric acid?
2 Na + 2 HCl = H2 + 2 NACl
What coefficients can be used to balance this epuation H2 NaCl2 NaH Cl?
First off, it is going to be NaCl, not NaCl2 and Cl2, not Cl. Secondly, the balanced equation would be H2 + 2NaCl -> 2NaH + Cl2
