Answer:
The answer to your question is 3 moles of CO
Explanation:
Data
mass of CO = ?
moles of O₂ = 1.50
Balanced chemical reaction
2C + O₂ ⇒ 2CO
Process
To solve this problem use proportion and cross multiplication. Use the coefficients of the balanced equation.
1 mol of oxygen ------------------ 2 moles of CO
1.5 moles of oxygen ----------- x
x = (1.5 x 2) /1
-Simplification
x = 3 / 1
-Result
x = 3 moles of CO
Explanation:
the above process is done in very detail .
hope this is helpful.
Technically speaking, yes you can. Using a microscope though.
Answer:
The pH of the solution lies from 11 to 12.Hence, option e is correct.
Explanation:
The value of for caffine =
Initial
0 0.01 M 0
AT equilibrium:
x (0.01 -x)M x
Solving for x:
x = 0.0096 M
The pOH of the solution is given by :
pOH = 2.02
pH= 14 - pOH = 14 - 2.02 = 11.98
The pH of the solution lies from 11 to 12.
Answer:
See explanation
Explanation:
We have to remember that for any <u>equilibrium expression constant</u> we can use the general reaction:
With a equilibrium expression:
We have to <u>divide products by reagents and use the coefficient (in the balanced reaction) as exponents</u>. So:
The reaction is <u>already balanced</u>. So, we can write the equilibrium expression:
In this case, all the compounds have <u>gaseous state (g)</u>. So, we can change the concentration ([]) by the <u>pressure of each compound</u>:
