When the following equation is balanced the coefficient of oxygen is
__c3h4 + __o2 → __co2 + _h20
a. 1
b. 2
c. 3
d. 4

When the equation is balanced, the coefficient of oxygen is 4. The correct option is d. 4

The given equation is __C3H4 + __O2 → __CO2 + _H20

This is the equation of the reaction between Propyne (C₃H₄) and Oxygen(O₂) to give Carbon(IV)oxide(CO₂) and Water (H₂O).  

To determine the coefficient of oxygen when the equation is balanced,

First, we will write the balanced form of the equation.

C₃H₄ + O₂ → CO₂ + H₂O

To balance the equation, we will ensure that the same number of each element is represented on the reactant and product sides ( that is, obey the law of conservation of matter)

The balanced form of the equation is

C₃H₄ + 4O₂ → 3CO₂ + 2H₂O

C = 3

H = 4

O = 8

C = 3

H = 4

O = 8

Therefore, the equation is balanced

From the balanced equation, we can observe that the coefficient of oxygen is 4.

Hence, when the equation is balanced, the coefficient of oxygen is 4. The correct option is d. 4

organisms are more likely to be more preserved in mud than sand because mud is moist and wet, while sand is very dry.

- calcium has greater affinity to bond with electron receptors than hydrogen does and hence, it has the ability to replace hydrogen in most of its compounds.

- lithium has 2 valence electrons in the product because it can make only 1 bond with hydrogen. beryllium has 4 valence electrons in the product because it can only make 2 bonds. it has fewer electrons than neon and can react with electron donors. each hydrogen has 2 valence electrons, the same as helium.

- the covalent bond formed between carbon and hydrogen is polar because carbon is more electronegative than hydrogen and it attracts the bonded electron pair closer to itself, thus giving hydrogen a partial positive charge.

- a hydrogen bond is a relatively weak bond that hydrogen atoms make with the electronegative atoms nitrogen, oxygen or fluorine.

so the best choice is a.) 2 calcium (ca) atoms
