Answer: There are 6 different outcomes.
Explanation:
There are two options for procedure one (one or two steps) and three options for procedure two (one, two or three steps). If we multiply those options , the result is the total number of outcomes for the analysis.
2 x 3 = 6
These being
- One step on procedure one and one step on procedure two
- One step on procedure one and two steps on procedure two
- One step on procedure one and three steps on procedure two
- Two steps on procedure one and one step on procedure two
- Two steps on procedure one and two steps on procedure two
- Two steps on procedure one and two steps on procedure two
33.6
L1 mole of a gas occupies 22.4 Liters of a gas. So, 1.5 moles of gas occupies of gas. Hence, the volume of carbon dioxide occupied by it is 33.6 L
Answer:
4.0406
Explanation:
Given that:
Concentration = 0.286 M
Consider the ICE take for the dissociation of acetic acid as:
HClO ⇄ H⁺ + ClO⁻
At t=0 0.286 - -
At t =equilibrium (0.286-x) x x
The expression for dissociation constant of acetic acid is:
x is very small, so (0.286 - x) ≅ 0.286
Solving for x, we get:
x = 9.1071×10⁻⁵ M
pH = -log[H⁺] = -log(9.1071×10⁻⁵) = 4.0406
Answer:
10.
Explanation:
Hello,
In this case, for the given reaction:
By knowing the law of conservation of mass must be respected, the following coefficients do balance the chemical equation:
So the sum of all the coefficients is 10.
Regards.
