Answer: what the hell does that mean
Explanation:
It would have a solubility substance and surface
Answer:
According to Kinetic Molecular theory, Temperature is directly proportional to the Average Kinetic energy of a molecules.
Explanation:
If the mass of the particles in a container is constant, then its moving molecules cause the gas gets warmer. On collision of molecules, Kinetic energy of molecules get high, so as a result, temperature gets high.
Fast moving of particles increases the temperature.
Answer:
Molarity of the packet is 0.5M
Explanation:
In the reaction of acetic acid with NaOH:
CH₃COOH + NaOH → CH₃COO⁻ + H₂O + Na⁺
<em>1 mole of acetic acid reacts with 1 mole of NaOH.</em>
<em />
When you are titrating the acid with NaOH, you reach equivalence point when moles of acid = moles of NaOH.
Moles of NaOH are:
3.0mL = 3.0x10⁻³L ₓ (0.1 mol / L) =<em> 3.0x10⁻⁴ moles</em> of NaOH = moles of CH₃COOH.
Now, you find the moles of acetic acid in the hot sauce packet. But molarity is the ratio between moles of the acid and liters of solution.
As you don't know the volume of your packet, <em>you can assume its density as 1g/mL. </em>Thus, volume of 0.6g of hot sauce is 0.6mL = 6x10⁻⁴L.
And molarity of the packet is:
3.0x10⁻⁴ moles acetic acid / 6x10⁻⁴L =
<h3>0.5M</h3>
Answer:
John Newlands propuso su ley de octavas en 1864 en la que organizó todos los elementos conocidos en ese momento en una tabla en orden de masa atómica relativa. Cuando hizo esto, descubrió que cada elemento era similar al elemento ocho lugares más adelante.
