The magnetic field can be reversed by switching the poles of the core.
Answer:
Gases, liquids and solids are all made up of atoms, molecules, and/or ions, but the behaviors of these particles differ in the three phases. ... gas are well separated with no regular arrangement. liquid are close together with no regular arrangement. solid are tightly packed, usually in a regular pattern.

Answer:
C₆H₁₅O₃N + H₂O ⇄ C₆H₁₅O₃NH⁺ + OH⁻
Explanation:
A Bronsted-Lowry base is defined as a substance than can accept a proton, H⁺.
When triethanolamine, C₆H₁₅O₃N, reacts with water, H₂O, as follows:
<h3>C₆H₁₅O₃N + H₂O ⇄ C₆H₁₅O₃NH⁺ + OH⁻</h3><h3 />
As you can see, in this reaction, triethanolamine is able to accept a proton that is given for the water.
Answer:
Phenol red indicator.
Explanation:
- Phenol red indicator is an organic dye which works as an indicator in the pH range (6.8 - 8.4) for acid-base reactions.
<em>The color in acidic solutions is yellow and in basic solution is red.</em>
Answer:
3.5 atm
Explanation:
Given data
- Initial pressure (P₁): 47.9 atm
- Initial volume (V₁): 21 L
We can find the maximum pressure that the gas can exert (final pressure) using Boyle´s law.
P₁ × V₁ = P₂ × V₂
P₂ = P₁ × V₁ / V₂
P₂ = 47.9 atm × 21 L / 290 L
P₂ = 3.5 atm
