Independent Variables are changes that occur in an experiment that are directly caused by the experimenter (you.)
Dependent Variables are changes that occur due to independent variables.
Controlled Variable is anything else that could influence the dependent variables.
Answer:
<em>The correct option is e. Extremophiles</em>
Explanation:
Archaea are prokaryotic organisms which were formerly separated from the bacteria domain.
Extremophiles can be described as organisms that have the ability to live in extreme conditions. Archaea have the ability to live in extreme environmental conditions such as a volcano vent, an extreme saline condition or extreme low-temperature conditions. Hence, archaea are also known as extremophiles. These organisms can thrive in extreme, harsh conditions which none other organisms can.
Answer:
It is fairly obvious that zinc metal reacts with aqueous hydrochloric acid! The bubbles are hydrogen gas. ... In fact, electrons are being transferred from the zinc atoms to the hydrogen atoms (which ultimately make a molecule of diatomic hydrogen), changing the charges on both elements.
Explanation:
Answer:
k = -0.0525 s⁻¹
Explanation:
The equaiton for a first order reaction is stated below:
ln[A]=−kt+ln[A]₀.
[A] = 5.50 x 10⁻³ M
[A]₀ = 7.60 x 10⁻² M
t = 85.0 - 35.0 = 50.0 s
The rate constant is represented by k and can be calculated substituting the values given above:
k = (ln[A]₀ - ln[A])/t
k = (ln5.50 x 10⁻³ M - ln7.60 x 10⁻² M)/50.0s
k = -0.0525 s⁻¹
