In a manufacturing process why would you prefer not to have a limiting reactant?
Answer:
The limiting reagent is the reactant that is completely used up in a reaction, and thus determines when the reaction stops. ... The limiting reagent is the one that is totally consumed; it limits the reaction from continuing because there is none left to react with the in-excess reactant.

whats the balanced chemical equation for the standard formation reaction of solid glucose, where everything can only have 1 mole with physical states.
Answer:
6C(s) + 6H2(g) + 3O2(g) --------------------> C6H12O6(s).
Explanation:
One of the examples under the type of sugar; monosaccharide(simple sugar) is the glucose. Glucose(with IUPAC name as D-glucose) as a monosaccharide (simple sugar) has the molar mass of 180.156 g/mol and a Melting point of 146 °C.
Thus, the unbalanced chemical reaction for the formation of glucose is given below;
C(s) + H2(g) + O2(g) --------------------------> C6H12O6(s) ΔH°f = -1273.1KJ/mol.
The balanced chemical reaction for the formation of one mole of glucose is given as;
6C(s) + 6H2(g) + 3O2(g) --------------------> C6H12O6(s).
The balanced chemical equation for the standard formation reaction of solid glucose is: [tex]\mathbf{6C_{(s)} + 6H_{2(g)} +3O_2_{(g)} \to C_6H_{12}O_{6} _{(s)} \ \ \ }[/tex]
Glucose is a simple sugar of a class of carbohydrates known as monosaccharides. It is the principal metabolite for energy production in the human body.
The formation of solid glucose [tex]\mathbf{C_6 H_{12} O_6_{(s)}}[/tex] occurs by the reaction of carbon, hydrogen, and oxygen.
The reaction formation of the solid glucose is:
[tex]\mathbf{C_{(s)} + H_{2(g)} +O_2_{(g)} \to C_6H_{12}O_{6} _{(s)} \ \ \ \Delta H_f^0= -1273.1 \ kJ/mol}[/tex]
Now, the balanced chemical equation can be expressed as follows;
[tex]\mathbf{6C_{(s)} + 6H_{2(g)} +3O_2_{(g)} \to C_6H_{12}O_{6} _{(s)} \ \ \ }[/tex]

Which is the IUPAC name for NO?
Answer:
Nitrogen (ii) oxide
Explanation:
To know the IUPAC name for NO, we shall determine the oxidation number of N in NO.
NOTE: The oxidation number of oxygen (O) is always – 2.
Thus the oxidation number of N in NO can be obtained as follow:
N + O = 0 (ground state)
N + (– 2) = 0
N – 2 = 0
Collect like terms
N = 0 + 2
N = +2
Thus, the oxidation number of Nitrogen (N) in NO is +2.
Therefore, the IUPAC name for NO is Nitrogen (ii) oxide

Perform a DNA extraction from green peas at home or school lab, under adult supervision, by following the given procedure carefully.
Procedure for DNA extraction:
To half cup of split peas, add 1/8 teaspoon of salt and one cup of cold water.
Transfer this mixture in a blender and blend it on high speed for 15 seconds.
Filter the blended mixture, using a strainer, into a measuring container. Observe the amount of mixture you obtain after filtration. Add liquid detergent equal to 1/6 volume of the obtained pea mixture.
Mix by swirling. Allow the mixture to rest for about five to ten minutes.
Transfer this mixture to test tubes. Fill the tubes to about 1/3 of their volume.
Add a pinch of meat tenderizer to each of these tubes. Mix gently to avoid damaging the DNA.
Tilt the test tube, and pour alcohol (75% isopropyl alcohol or 95% ethanol) down the sides of the tube. Add alcohol to about 2/3 volume of the tube. You will obtain two layers. The layer at the top contains the DNA.
Now that you are done with the DNA extraction process, answer the following questions:
What purpose does blending the pea mixture serve?
Why do you need to add liquid detergent?
What role does the meat tenderizer play?
Why is alcohol added and why does the DNA get extracted in the alcohol layer?
Answer:
Blending is done to break open, or lyse, the cells.
DNA resides in the nucleus, which is enclosed by the nuclear membrane. The nucleus is further enclosed by the cell membrane. So, to get the DNA, we need to break open both the membranes. Cell membranes are made up of lipids and proteins. The detergent molecules to attach to the cell and nuclear membranes, causing them to break open.
Meat tenderizer contains the enzyme protease that helps cleave proteins. Even after breaking open the nucleus and cell membrane, the DNA is still protected by cell proteins. Meat tenderizer cleaves the proteins, leaving behind only the DNA molecule.
DNA is insoluble in alcohol and hence, when alcohol is added, it precipitates out the DNA.

In the periodic table hydrogen is placed in Group 1A (group 1) and helium is placed in Group 8A (group 18). The most likely reason for this is:
Answer:
This question appears incomplete
Explanation:
This question appears incomplete because of the absence of options. However, hydrogen is placed in group 1 because it has just one electron in it's outermost shell (which happens to be the only shell it has) just like every other group 1A/group 1 element. While helium is placed in group 8A/group 18 because it has a completely filled outermost shell (which is also the only shell it has) just like every other element in group 8A/group 18.
In the periodic table hydrogen is placed in Group 1A (group 1) and helium is placed in Group 8A (group 18). The most likely reason for this is configuration, energy level and properties.
Hydrogen is located in group 1 of the periodic table, although its electronic configuration is 1s¹ and its properties do not correspond to those of the alkali metals of that group. But in its electronic configuration you can see that it has only one electron in its outermost shell (which turns out to be the only shell it has), just like any other element of group 1A /group 1, so it is located in that group.
On the other hand, although the electronic configuration of helium is 1s², this element does not appear in group 2 of the periodic table of elements, but is placed in group 18. This is because it has the energy level complete, so it has the properties of a noble gas, that is, it is inert (it does not react), and it is a colorless and odorless monatomic gas.
In summary, in the periodic table hydrogen is placed in Group 1A (group 1) and helium is placed in Group 8A (group 18). The most likely reason for this is configuration, energy level and properties.

Where else have you heard the term conservation? How does the term's meaning in that other context relate to its meaning in chemistry? please help me im so confuseddd
Answer:
See the answer below
Explanation:
Conservation is also a topic in Biology and it refers to the practice of managing natural resources - both living and non-living - with the aim of preserving them to secure the future of the human population.
Conservation in Chemistry refers to the property of chemical reactions in which no new matter or energy is created nor destroyed during the course of the reactions, although they can be converted from one form to another.
Conservation in Biology and Chemistry can be likened to each other based on the fact that both deal with preservation. While conservation in Biology focuses on how the ecosystem can be preserved, conservation in Chemistry deals with the preservation of matter/energy.
