Answer:
6.46 × 10⁻¹¹ M
Explanation:
Step 1: Given data
pH of the solution: 3.81
Step 2: Calculate the pOH of the solution
We will use the following expression.
pH + pOH = 14.00
pOH = 14.00 - pH = 14.00 - 3.81 = 10.19
Step 3: Calculate the concentration of OH⁻ ions
We will use the definition of pOH.
pOH = -log [OH⁻]
[OH⁻] = antilog -pOH = antilog -10.19 = 6.46 × 10⁻¹¹ M
The answer is A because the information is stating that when one chemical combined with another chemical, it had new properties which is essentially answer choice A
Answer:
Explanation:
In stoichiometry, molar mass is used to convert between the mass of a substance and how many moles of a substance.
Answer:
false
Explanation:
earth is larger than mars so it has more gravity
1. Schrodinger's Cat- A many world's theory that describes quantum coherence and phenomenon.
2. Newton's 1st Law- says that objects in rest will stay in rest and objects in motion will stay in motion. The most important lesson here is that an object in rest may not be in rest position.
3. Ohms law- says the current passing through an area is directly proportional to the voltage
