because salt contains stuff
Answer:
A description of the experiment the chemicals were used for.
Explanation:
A chemical waste label is required to provide information about any hazardous waste present in the container. Some details are mandatory to mention of the chemical waste label to prevent any accident while doing the experiment, that includes:
- Chemical compound's name present in the container.
- Composition and physical state of the waste.
- Hazardous properties of the waste.
- The date of manufacturing.
- Amount of chemical compounds filled in the container.
A chemical waste label does not mention or describe the experiment for which the chemicals were used for, scientists, teacher or students should have knowledge of the chemical composition by reading their names and evaluate themselves on which chemical should be used for which experiment.
Hence, the correct answer is "A description of the experiment the chemicals were used for."
What will happen in a case there is different number of electrons compare to protons is<em> D: The particle is considered an</em><em> ion.</em>
<em></em>
- An ion can be regarded as atom or molecule which posses some amount of electron more than amount of protons and vice versa.
- It can be regarded as molecules that has a charge. i.e ( -ve or +ve)
- When the number of electron in this molecules or atom is more that that of the present protons, then the ion is negatively charged ion.
- When a particles posses less electron compare to the present protons then the ion is positively charged.
Therefore, an ion can be charged positively and it can be charged negatively

Answer:
8.34 moles
Explanation:
We are given 8.34 moles.
We need to find moles: 8.34
It helps to map out how you will navigate through your unit analysis problem before setting it up.
You are given moles and need grams. What can be used as a conversion factor from moles to grams? Molar mass. We are working with aluminum, so we will need the molar mass of aluminum. My Periodic Table tells me the molar mass of aluminum is approximately 27 g/mol. Now we are ready to set up the unit analysis.
Moles must go on the bottom so that they cancel. Notice how our number of significant figures is 2, so the answer must round to 16 g Al.
<h3>
Answer:</h3>
16 grams
