Answer:
C. AB + XY--> AY + BX
Explanation:
In a double replacement reaction occurs a new combination of the species present in the reactants
<u>1) balanced chemical equation</u>
<u>2) convert mass of CO₂ to moles</u>
<u>3) multiply by molar ratio</u>
<u />
<u />
4) convert moles of C₄H₁₀ to mass
= 23.7 grams of C₄H₁₀ is needed to produce 71.9 grams of CO₂
The bond that exist between two oxygen atoms is
called a double covalent bond. This bond involves the sharing of four electrons
to obtain a more stable structure. This type of bond is much stronger than the
single covalent bond. They are much harder to break.
Two or more atoms<span> may </span>bond<span> with each other to form a molecule. When two hydrogens and an oxygen share electrons via covalent </span>bonds<span>, a water molecule is formed. Chemical reactions </span>occur<span> when two or more </span>atoms bond<span> together to form molecules or when bonded </span>atoms are broken<span> apart.</span>
Explanation:
The value of equilibrium constant doesn't change when a catalyst is added.
Equilibrium constant depends on Concentration of reactants , Pressure and Temperature.
