Answer:
This substance is basic.
Explanation:
The milk of Magnesia, a type of medication which can help people with heartburn and with a pH of 10.5 is a basic solution.
- Bases are certain metallic oxides, metallic hydroxides and aqueous ammonia.
- They have the following properties:
- On the pH scale, they have a value between 7-14
- They turn red litmus paper blue.
- Bases are electrolytes.
- They have a bitter taste.
- They are soapy or slippery to feel.
Answer:
The correct answer is due to the difference in pressure inside and outside the bottle.
Explanation:
Liquids have melting and boiling points that depend on pressure and temperature. The pressure inside the bottle is higher than the pressure outside. This causes the melting point to drop, making the liquid freeze at a lower temperature than if it were at atmospheric pressure, and therefore has a lower temperature than it would freeze at atmospheric pressure. When the bottle is uncovered, the liquid becomes an atmospheric pressure, and due to the temperature acquired when the bottle was closed the liquid freezes.
Have a nice day!
The polarity of a bond between two elements can be best determined by difference in the values of electronegativity.
<h3>Determination of polarity of bond</h3>
The polarity of a covalent bond can be determined by determining the difference in electronegativity between the two bonded atoms. Electronegativity is defined as the tendency of an atom to attract electrons to itself.
So we can conclude that the polarity of a bond between two elements can be best determined by difference in the values of electronegativity.

Answer:
. CuO
Explanation:
Since oxygen also has -2 the valency will cancel out the +2 on Cu leaving CuO
