Answer:
<em>Because the individual components of any mixture are not</em> <u>bonded</u> t<em>o each other, the composition of those components can vary. Also, some of the </em><u>physical</u> <em>properties of the individual components are still noticeable.</em>
Explanation:
A <em>mixture</em> is a combination of two or more pure substances that are present in any proportion and each pure substance keeps its own physical and chemical properties.
As oppossite to mixtures, the compounds are pure substances formed by two or more different elements which are chemically bonded to each other. So, while in the compounds the components (elements) are bonded in a fixed proportion, and their composition cannot vary, in the mixtures each component may be present in any proportion, which means that the <em>composition can vary</em>.
Take, for example, the simple case of talc and iron particles.This is <em>a mixture</em>. Talc is <u><em>not bonded</em></u> to the iron particles, and so their proportion, <em>the compositoin</em>, can vary in any form. Aslo, both talc and iron particles keep their own <u><em>physical properties</em></u>: you can perfectly separate the mixture by using a magnet to attract the iron particles, because they have not lost their magnetic property (a physical one).
<span>Most living things on Earth are made of carbon.
Living things need carbon in order to live, grow, and reproduce.
Carbon is a finite resource that cycles through the Earth in many forms.
This makes carbon available to living organisms and remains in balance with other chemical reactions in the atmosphere and in bodies of water like ponds and oceans.</span>
<h3><u>Answer;</u></h3>
C.The oxidation state of all the atoms should change.
<h3><u>Explanation;</u></h3>
- A redox reaction which is oxidation-reduction reaction is a type of chemical reaction that involves a transfer of electrons between two species.
- An oxidation-reduction reaction is any chemical reaction in which the oxidation number of a molecule, atom, or ion changes by gaining or losing an electron.
- In a redox reaction, the total number of electrons lost by the reducing agent must be equal to the number of electrons gained by the oxidizing agent.

In terms of workplace we need our safety measures to have a safe and to ensure the awareness of health and safety of every personnel, waste disposal and the security. Speaking of security every laboratories have their own security, well organized and the most important to store information safely and the other data. The information can be stored in LIMS (laboratory information management system) by registration all the samples. You can any kind of device to upload the information.
