Explanation:
because there are 4 Iodines on the left, we'll put. 4 in front of NaI to balance it. This would result in 4 Na on the left, so we'll put a 2 in front of Sodium Sulfate to balance the right side. Now we have 4 Na and I on both side, as well as 2 Sulfate on both sides. Pb is already balanced. The equation is now complete.
Answer:
0.48atm
Explanation:
Firstly, we need to know the mole ratio of the oxygen gas involved. To do this, we simply place the number of moles of the oxygen over the sum of both gases.
This would be 3/(3+7) = 0.3
Now, to get the partial pressure contributed by the oxygen gas, we simply multiply the 0.3 by the total pressure
Hence, the partial pressure of oxygen = the mole fraction of oxygen * the total pressure.
= 0.3 * 1.6 = 0.48atm
Answer:
0.220 M
Explanation:
<em>In the equivalence point, [H⁺] = [OH⁻]</em>.
This means we can use the formula C₁V₁=C₂V₂
Where
So we <u>compute the given data in the formula</u> to calculate C₂:
- 0.0500 M * 17.6 mL = C₂ * 4.00 mL
1 - 118, depending on the element
the specific heat capacity is the energy needed to raise the temperature of 1kg of that substance by 1 degree
