If the nonmetal is reacting with atom of another nonmetal, then it shares electrons with the other atom in form of a covalent bond.
If the nonmetal is reacting with an atom metal, then the nonmetal gains an electron from the metal atom, it's called ionic bond.
Answer:
ionic
ionic
covalent
covalent (i think)
Explanation:
ionic= donate electrons (gain/lose)... (results in ions that have +/- charge, are no longer neutral)
covalent= share electrons
Answer:
Increases the greenhouse effect and increases the absorption of radiation
Explanation:
An increase in carbon dioxide increases the greenhouse effect and increases the absorption of radiation emitted from Earth's surface. Carbon dioxide has the ability to absorb radiation emitted from Earth's surface. This is because carbon dioxide is an effective heat trapping greenhouse gas.
The answer is CH4, 2O2, ? CO2 H20.
In the reaction, the the bonds in the methane and oxygen come apart, the atoms rearrange and then re-bond to form water and carbon dioxide. The little number written at the lower right after an atom (subscript) tells how many of that atom are in the molecule. The big number written in front of a molecule (coefficient) shows how many of that molecule there are. All the atoms in the products come from the atoms in the reactants.
The reactants are on the left side of the equation and the products are on the right. In the reaction, the bonds in the methane and oxygen come apart, the atoms rearrange and then re-bond to form water and carbon dioxide
All the atoms in the reactants form the products so the mass of the reactants and the products is the same. No new atoms are created and no atoms are destroyed.
