Answer
A runner ran 20 miles in 150 minutes. If she runs at that ... run in 15 minutes? How fast is she running in miles per hour? What is her pace in minutes per mile?
Explanation:
Answer:
9 × 10⁻³ mol·L⁻¹s⁻¹
Explanation:
Data:
k = 1 × 10⁻³ L·mol⁻¹s⁻¹
[A] = 3 mol·L⁻¹
Calculation:
rate = k[A]² = 1 × 10⁻³ L·mol⁻¹s⁻¹ × (3 mol·L⁻¹)² = 9 × 10⁻³ mol·L⁻¹s⁻¹

Explanation:
Amines are organic compounds derived from ammonia by replacing the hydrogen atoms, one at a time with carbon-containing groups. The functional groups are R-NH₂, R₂-NH, and R₃-N
Amines are classified into primary, secondary, or tertiary according to the number of substituted hydrogen.
From the given question.
A compound with the molecular formula C₅H₁₃N was given;
The possible eight structural formula of the compound and those that exhibit chirality can be seen in the attached image below.
Answer:- b. +3
Explanations:- Charge of a metal ion is equal to the number of valence electrons it has as it loses these electrons to have its nearest noble gas like electron configuration.
Al has 3 valence electrons and being a metal it loses all of these and so the charge of Al ion is +3. It could be shown as:

So, the right choice is b. 3+.
