Answer:
<h2>9.03 × 10²³ atoms </h2>
Explanation:
The number of atoms of Al can be found by using the formula
<h3>N = n × L</h3>
where n is the number of moles
N is the number of entities
L is the Avogadro's constant which is
6.02 × 10²³ entities
From the question we have
N = 1.5 × 6.02 × 10²³
We have the final answer as
<h3>9.03 × 10²³ atoms</h3>
Hope this helps you
Answer:
134.8 seconds is the half-life (in seconds) of the reaction for the initial 
concentration
Explanation:
Half life for second order kinetics is given by:
Integrated rate law for second order kinetics is given by:
= half life
k = rate constant
= initial concentration
a = Final concentration of reactant after time t
We have :
Initial concentration of ![C_2F_4=[a_o]=\frac{0.438 mol}{2.42 L}=0.1810 mol/L](https://tex.z-dn.net/?f=C_2F_4%3D%5Ba_o%5D%3D%5Cfrac%7B0.438%20mol%7D%7B2.42%20L%7D%3D0.1810%20mol%2FL)
Rate constant = k = 
134.8 seconds is the half-life (in seconds) of the reaction for the initial concentration
Answer:
what is the product of the reaction?
What does it form?
The concentration (in M) of hydronium ions in a solution at 25. 0 °C with a POH of 3. 58 Is 3.8× 10⁻¹¹ M
pOH is the measure of basic nature of a solution by evaluating the [OH⁻] concentration.
pH is measure of acidic nature of a solution by evaluating the [H⁺] concentration. It is the negative logarithm of the hydroxide ion concentration. It gives hydronium ions on dissociation.
Given,
pOH = 3.58
Temperature = 25°C = 298K
We know that pH + pOH =14
pH + 3.58 = 14
pH = 10.42
pH is the negative logarithm of hydrogen ion concentration.
At 25°C, the relation of pH and [H⁺] concentration is as follows:
∴ pH = -log [H⁺]
⇒ 10.42 = -log [H⁺]
⇒log [H⁺] = -10.42
⇒ [H⁺] = antilog (-10.42)
⇒[H⁺] =3.8× 10⁻¹¹ M
The concentration (in m) of hydronium ions in a solution at 25. 0 °C with a POH of 3. 58 Is 3.8× 10⁻¹¹ M
