When water molecules align with each other, a weak bond is established between the negatively charged oxygen atom<span> of one water molecule and the positively charged </span>hydrogen atoms<span> of a neighboring water molecule. The weak bond that often forms between </span>hydrogen atoms<span> and neighboring atoms is the hydrogen bond.</span>
Answer:
A. When two boundary plates are moving slowly toward each other.
Answer:
2H₂ + O₂ → H₂O
Explanation:
The unbalanced equation is
2H₂ + O₂ → H₂O
In a balanced chemical equation, the number of moles of species on both sides of the expression must be the same.
2H₂ + O₂ → H₂O
Reactant Product
H O H O
Number of moles 4 2 2 1
We see that the number of hydrogen and oxygen on both sides of the expression differs significantly.
NaCl + H2O = HCl + NaOH
FIRST write the equation and balance the equation THEN convert the volume of the gas to moles of the gas PV=nRT THEN according to the stoichiometry of the reaction one mol of gas is produced by one mol of salt. Convert the mol of gas to mol of salt FINALLY calculate the molar mass of the salt and convert the mol of salt to g of salt (m= nxMM)
Natural sources include decomposition,ocean release and respiration.
Human sources come from activities like cement production, deforestation as well as the burning of fossil fuels like coal,oil and natural gas.
