Answer:
[H_3 O^+] = 1.0 ×10^-13
Explanation:
If we multiply the left side we get, 1e - 13. We add 13 to the right side while subtracting the remaining value from the left side (H3O+) than combine like terms. As you will get pH = 13.00
Answer:
0.07172 L = 7.172 mL.
Explanation:
- We can use the general law of ideal gas: <em>PV = nRT.
</em>
where, P is the pressure of the gas in atm (P = 1.0 atm, Standard P).
V is the volume of the gas in L (V = ??? L).
n is the no. of moles of the gas in mol (n = 3.2 x 10⁻³ mol).
R is the general gas constant (R = 0.0821 L.atm/mol.K),
T is the temperature of the gas in K (T = 273 K, Standard T).
<em>∴ V = nRT/P =</em> (3.2 x 10⁻³ mol)(0.0821 L.atm/mol.K)(273 K)/(1.0 atm) = <em>0.07172 L = 7.172 mL.</em>
Answer:
A
Explanation:
Increasing the the temperature would favour the endothermic reaction which is the forward direction however increasing the pressure would make the reaction try to counteract this change by favouring the reaction that would create more products so the equilibrium will shift left instead of right.
Hope this helps.
How does the position of the Sun, moons, planets and stars affect a person's personality traits and daily behavior patterns
Explanation:
The question that cannot be answered scientifically from the given choices is "how does the position of the Sun, moons, planets and stars affect a person's personality traits and daily behavior patterns".
This problem is off the jurisdiction of natural science.
- Scientific questions are usually empirical in nature and draws relationship between two variables.
- Usually, one variable changes and the other is affected.
- This problem stated is subjective and not scientific.
- Humans have a wide range of personality traits.
- This problem can be solved using a psychological analysis.

Answer:
20 m/s^2
Explanation:
given,
final velocity (v) = 6000m/s
initial velocity (u) = 0m/s
time taken (t) = 5 minutes
= 5×60second
= 300second
acceleration(a) = ?
we know that,
a = (v-u)/t
= (6000-0)/300
= 20 m/s^2
