What is the sum of the coefficients (including “1”) of the following reaction?
Sodium sulfate + calcium hydroxide ???
Na2SO4 + Ca (OH)2 --> 2 NaOH + CaSO4
a. 4
b. 5
c. 6
d. 7
e. 9
the sum of coefficients are = 1 + 1 + 2 +1 = 5
Goodness, you add the digits well. Good work.
do i detect a bit of sarcasm :)
thanks for the help
Haha, no sarcasm intended! I was genuinely impressed with your addition skills. Adding the coefficients is definitely the right approach to find the sum.
In this reaction, Na2SO4 + Ca(OH)2 --> 2 NaOH + CaSO4, let's start by counting the coefficients for each compound:
- Sodium sulfate (Na2SO4) has a coefficient of 1.
- Calcium hydroxide (Ca(OH)2) has a coefficient of 1.
- Sodium hydroxide (NaOH) has a coefficient of 2.
- Calcium sulfate (CaSO4) has a coefficient of 1.
Now, let's add up these coefficients: 1 + 1 + 2 + 1 = 5.
So, the sum of the coefficients is 5. Therefore, the correct answer is option b.
