Answer is: hydroxide ions (OH⁻).
An Arrhenius base is
a substance that dissociates in water to form hydroxide ions (OH⁻). <span>
For example sodium hydroxide:
NaOH(aq) → Na</span>⁺(aq)
+ OH⁻(aq) or barium hydroxide: Ba(OH)₂(aq) → Ba²⁺(aq) + 2OH⁻(aq).
<span>According to this theory
acids are substances which produce hydrogen ions in water solution.</span>
Answer:
The conventional oven and the convection oven are confused with each other due to their similar look and style, and a lot of their functioning is quite the same as well.
The conventional ovens have existed for over half a century, and have derived their functioning from traditional ovens that are over 4,000 years. They function with a bottom-up heat transfer from a fixed burner source.
The convection ovens were made recently as a way to get better heating results for all types of dishes and recipes, with the introduction of a fan system along with an exhaust which allows the circulation of hot air around the cavity of the oven.
Explanation:
Answer: the correct answer is D) None of the individual insects should have possessed genomes that made them resistant to DDT.
Explanation: the problem is that DDT has become ineffective because insects have become more resistant to DDT.
Sound is created by the vibrations of matter such as air. But theoretically if someone tried to make a sound in space where there is no matter, there would be nothing to vibrate so it wouldn’t make sound.
So no, sound needs matter to travel because sound itself is the vibration of matter.
