I believe the answer would be halogens
Answer:
- Scientific question: does life exist on other planets?
- Non-scientific question: there are aliens that look like people?
Explanation:
A scientific question is a coherent question that can be used to develop a scientific hypothesis. Thus, a scientific question must be testable, verifiable, measurable and relevant to the topic of study. In the scientific method, the hypothesis is subsequently tested by experimental or observational procedures, where the results can be used to understand some particular aspect of the real world. On the other hand, a non-scientific question is a light conjecture which cannot be proved by using the scientific method.
The pH is the measure of hydrogen ion concentration in a solution. The hydrogen ion concentration at pH 1.25 is
.
<h3>How to calculate hydrogen concentration?</h3>
The pH is the negative logarithmic value of the hydrogen ion concentration in the sample.
The pH can be expressed as:
![\rm pH=-log[H^+]](https://tex.z-dn.net/?f=%5Crm%20pH%3D-log%5BH%5E%2B%5D)
The hydrogen ion concentration can be given as:
![\rm [H^+]=10^{-pH}](https://tex.z-dn.net/?f=%5Crm%20%5BH%5E%2B%5D%3D10%5E%7B-pH%7D)
The given pH is 1.25 The hydrogen ion concentration is given as:
![\rm [H^+]=10^{-1.25}\\H^+=0.05\;M\\H^+=5\;\times\;10^-^2\;M](https://tex.z-dn.net/?f=%5Crm%20%5BH%5E%2B%5D%3D10%5E%7B-1.25%7D%5C%5CH%5E%2B%3D0.05%5C%3BM%5C%5CH%5E%2B%3D5%5C%3B%5Ctimes%5C%3B10%5E-%5E2%5C%3BM)
The hydrogen ion concentration in the solution is

Answer:
these are small organism that can not seen by naked eyes
The elements that will ionically bond with halogens in a 1 is to 1 ratio are the metals in the group or column 1 in the periodic table. These are alkali metals or the s-block in the periodic table. One example is sodium chloride where sodium ionically bonds with chlorine in a 1 is to 1 ratio.
