Hello,
In this case the undergoing chemical reaction is:
Next we identify the limiting reactant with the given amounts of methane and oxygen by computing the available moles of methane and the moles of methane consumed by the 133 g of oxygen:
In such a way, the limiting reactant is methane with 0.75 moles which produce the following mass of carbon dioxide:
Best regards.

Explanation:
Convection requires a fluid material that can move around. Typically, metals are solid, not fluid, and therefore do not participate in convection. ... This means that metal can be either a good heat shield, a mediocre heat shield, or a bad heat shield, depending on how we use it.
Answer:
Option A = sodium and bromine
Explanation:
Sodium is metal while bromine is non metal. The bond formed between them is ionic.
Ionic bond:
Ionic bond is formed by the complete transfer of electron form metal to non metal.
Sodium is belongs to the group one while bromine is present in group seventeen. The number of valance electron of bromine are seven. Bromine require one electron to complete the octet, while sodium lose its one valance electron to gain noble gas stable electronic configuration. Thus sodium transfer its electron to bromine and gain positive charge and bromine gain its electron and form negative ion. The forces present between them are electrostatic forces which are very strong.
