Identify the type of reaction described in the sentence below. then, write a chemical equation. be sure to specify the states of
1 answer:
Answer : The type of reaction described in the sentence is Synthesis or Combination
Explanation :
The balanced equation for the reaction between Phosphorous and Oxygen gas can be written as
From the above equation we can see that there are two different reactants ( P and O₂ ) which are combining with each other to give a single product.
This type of reaction is known as Combination or Synthesis.
A general form of Synthesis reaction is given below.
Here we can conclude that a synthesis / combination reaction is the one where 2 or more reactants combine together to give only one product .

Answer: 12
Explanation.
This problem was recently posted and deals with the conversion of units,so I give the same answer.
You need to convert the 9 quibs of skvarnick to sleps, to determine how many sleps you have.
The conversion of units is easily undertaken once you build your conversion factors.
Conversion factors are ratios (fractions) equivalent to one, which permits use the identity property of the multiplication to change one unit to a different equivalent one.
Remember that the identity property of multiplication states that any amount multiplied by 1 remains unchanged, i.e.
Then, build your conversion factor from the definitions given:
- 12 sleps is equal to 9 quibs.
- 12 sleps = 9 quibs
- in virtue of the division property of equality, you can divide both sides by 12 sleps and get:
1 = 12 sleps / 9 quibs ← conversion factor
Now you can multiply the amount 9 quibs by the conversion factor, which is equal to 1, to find the equivalent amount of sleps:
- identity property: 9 quibs = 9 quibs × 1
- substitution property: 9 quibs = 9 quibs × 12 sleps/ 9 quibs
You can see that the unit quibs appear in the numerator and the denominator so it cancels out, and the result will be in sleps.
So, all you have to do now is the operations with the numbers:
9 quibs = (9 × 12 / 9) sleps = 12 sleps ← answer
