Answer:
12 mol O2
Explanation:
This is assuming you're using a combustion equation of
2 H2S + 3O2 -> 2H2O + 2SO2
Next time include the equation because that is where you will find your mol to mol ratio
8 mol H2S x (3 mol O2 / 2 mol H2S) = 12 mol O2
A. The box will move to the right
Answer:
2.5
Explanation:
From the question given above, the following data were obtained:
Molarity of NaOH = 3.0x10¯³ M
pOH =?
Next, we shall determine the concentration of the hydroxide ion in the solution. This can be obtained as follow:
NaOH (aq) —> Na⁺ (aq) + OH¯ (aq)
From the balanced equation above,
1 mole of NaOH produced 1 mole of OH¯.
Therefore, 3.0x10¯³ M NaOH will also produce 3.0x10¯³ M OH¯.
Finally, we shall determine the pOH of the solution. This can be obtained as illustrated below:
Concentration of hydroxide ion [OH¯] = 3.0x10¯³ M
pOH =?
pOH = – Log [OH¯]
pOH = – Log 3.0x10¯³
pOH = 2.5
Thus, the pOH of the solution is 2.5
Electron affinity is a measure of the tendency of a neutral atom to gain electrons and form a negative ion. It can be represented by a general equation:
X + e- → X-
The value of electron affinity decreases on moving down a group. This is because on moving down a group the atomic size increases as a result the added electron feels less pull or attraction towards the nucleus.
In group 14, Carbon 'C' is the first member and therefore will have the highest electron affinity.
Ans : A) Carbon
Not sure, but I believe it is... Sodium Nitrate?
