<span>The choices are as follows:
h2o + 2o2 = h2o2
fe2o3 + 3h2 = 2fe + 3h2o
al + 3br2 = albr3
caco3 = </span><span>cao + co2
The correct answers would be the second and the last option. The equations that are correctly balanced are:
</span> fe2o3 + 3h2 = 2fe + 3h2o
caco3 = cao + co2
To balance, it should be that the number of atoms of each element in the reactant and the product side is equal.
Answer:
The statue of liberty was made of copper. Copper is extremely weather-resistant. It will gradually oxidize copper chloride, which is greenish in

Answer: gasoline
Explanation: Gasoline is a mixture of many different hydrocarbons: alkanes (paraffins), cycloalkanes and alkenes (olefins). Salt and carbon dioxide are chemical compounds, aluminium (Al) is an chemical element.
The correct answer is potential because kinetic energy means it’s moving. however it is stored and has the potential to be used
Answer:
Unlike other noble gases, which are highly nonreactive, Kr and Xe have non-zero values of Electronegativity (3.00 and 2.60, respectively) because they do form compounds: indeed, the electronegativity is a fundamental property of atoms that defines how strong their pull on shared electrons is.
