As a skier goes down the hill:
A. <u>Gravitational potential energy to kinetic energy</u>
Answer:
The correct option is C.
Explanation:
If the system is present in the dynamic equilibrium, then the rate of sublimation of the NH4CI crystals is equal to the rate of production if the NH4CI vapors.
A dynamic equilibrium is defined as the reversible reaction repel to change its ratio of products, and reactants, but at equal rate substances keep moving between the chemicals, and there is no net change occurs.
So, the correct answer is option C. (The rate of sublimation of the NH4CI crystals is equal to the rate of solidification of the NH4CI vapors).
Answer:
270. mL
General Formulas and Concepts:
<u>Acid-Base Titrations</u>
Dilution: M₁V₁ = M₂V₂
- M₁ is stock molarity
- V₁ is stock volume
- M₂ is new molarity
- V₂ is new volume
Explanation:
<u>Step 1: Define</u>
<em>Identify</em>
[Given] V₂ = 629.1 mL
[Given] M₂ = 11.2 M
[Given] M₁ = 26.1 M
[Solve] V₁
<u>Step 2: Find Stock Volume</u>
- Substitute in variables [Dilution]: (26.1 M)V₁ = (11.2 M)(629.1 mL)
- Multiply: (26.1 M)V₁ = 7045.92 M · mL
- Isolate V₁ [Cancel out units]: V₁ = 269.959 mL
<u>Step 3: Check</u>
<em>Follow sig fig rules and round. We are given 3 sig figs as our lowest.</em>
269.959 mL ≈ 270. mL
Hello <span>Tyairamifflin6058</span>
Question: <span>Differences in strength between covalent bond ionic bond and hydrogen bond?
Answer:
</span>
Ionic bonds:<span> These form because of the transfer of an electron from one atom to another atom.
</span>Covalent bonds:<span> These involve the sharing of electrons </span>between two different atoms.
Hope This Helps!
