Answer:

Explanation:
The correct answer of this questions is 38°c
Answer: a low
and low pH.
Explanation:
pH is the measure of acidity or alkalinity of a solution.
pH is calculated by taking negative logarithm of hydrogen ion concentration.
![pOH=-log[OH^-]](https://tex.z-dn.net/?f=pOH%3D-log%5BOH%5E-%5D)
Thus as pOH and
are inversely related, a solution having higher pOH will have less amount of
concentration. And a solution having more pOH will have less pH.
Thus a substance with a high pOH would likely have low
concentration and low pH.
Answer: Some natural disasters include: tornados, hailstorms, hurricanes, wild fires, flash floods, tsunamis, and earthquakes.
Answer:
0.1082M of Barium Hydroxide
Explanation:
KHP reacts with Ba(OH)2 as follows:
2KHP + Ba(OH)2 → 2H2O + Ba²⁺ + 2K⁺ + 2P²⁻
<em>Where 2 moles of KHP reacts per mole of barium hydroxide</em>
<em />
To solve this question we must find the moles of KHP in 1.37g. With these moles and the reaction we can find the moles of Ba(OH)2 and its molarity using the volume of the solution (31.0mL = 0.0310L) as follows:
<em>Moles KHP -Molar mass: 204.22g/mol-</em>
1.37g * (1mol / 204.22g) = 0.006708 moles KHP
<em>Moles Ba(OH)2:</em>
0.006708 moles KHP * (1mol Ba(OH)2 / 2mol KHP) =
0.003354 moles Ba(OH)2
<em>Molarity:</em>
0.003354 moles Ba(OH)2 / 0.0310L =
<h3>0.1082M of Barium Hydroxide</h3>
Based on the Hund's Rule, the three electrons in a 2p orbital are arranged as shown in option C.
<h3>What is an orbital?</h3>
The term orbital refers to a region in space where there is a high probability of finding the electron. We know that an electron in an atom could be defined by the use of four sets of quantum numbers which are;
- The principal quantum number
- The orbital quantum number
- The spin quantum number
- The magnetic quantum number
Hund's rule states that, electrons occur singly before pairing takes place. In this case, we can see that the only arrangement that obeys the Hund's Rule is option C.
