Answer:
neutral pH or neutral solution
Explanation:
when hydrogen ion concentration and hydroxide ion concentration the pH is neutral i.e. ph=pOH=7
Answer:
BaO
Explanation:
The barium oxide chemical formula is BaO. The molar mass is 153.33 g/mol. The molecule is formed by one barium cation Ba2+ and one oxide anion O2-. Both ions are bound by one ionic bond.
Answer:
Original temperature (T1) = - 37.16°C
Explanation:
Given:
Gas pressure (P1) = 2.75 bar
Temperature (T2) = - 20°C
Gas pressure (P2) = 1.48 bar
Find:
Original temperature (T1)
Computation:
Using Gay-Lussac's Law
⇒ P1 / T1 = P2 / T2
⇒ 2.75 / T1 = 1.48 / (-20)
⇒ T1 = (2.75)(-20) / 1.48
⇒ T1 = -55 / 1.48
⇒ T1 = - 37.16°C
Original temperature (T1) = - 37.16°C

<h3>What are hydrophilic substances?</h3>
The term hydrophilic substances is used to describe the substances that could dissolve in water. They are those substances that are water soluble. Somehow, the substances must be polar because in chemistry like dissolves like.
The hydrophobic substances are those substances that do not dissolve in water. They are nonpolar and interact with other nonpolar substances.
