When the ticket price was $15, a total of 180 people visited the art show as it denotes a point with most accuracy.
What is accuracy?Accuracy in terms of chemistry can be defined as to how close a measurement is to the true value.There are three types of accuracy:
1) Point accuracy-It means accuracy is present at that point of scale only.It does not give any information about the accuracy of the instrument.
2)Percentage of true value--It is the accuracy which is determined by identifying accuracy of the instrument and comparing it with the measured true value.
3)Percentage of scale range- It is the accuracy which determines accuracy of the measurement.
Accuracy of percentage of scale range type as the measurements are to be made within a range where the sample has to be measured.
Accuracy in case of instruments is neglected up to ±0.5 percent.

which bond type involves the sharing of valence electrons?
NEED HELP ASAP PLEASE!!!!
Answer:
Covalent Bond
Explanation:
A covalent bond involves electrons being shared between atoms. The most stable state for an atom occurs when its valence electron shell is full, so atoms form covalent bonds, sharing their valence electrons, so that they achieve a more stable state by filling their valence electron shell.
How many grams of Oz would be needed to produce 1.875 moles of aluminum?
4 AI + 3 O2 -> 2Al2O3
Answer:
1.4063 moles of oxygen are required
Explanation:
Based on the chemical equation:
4Al + 3O₂ → 2Al₂O₃
4 moles of aluminium react with 3 moles of oxygen.
To solve this question we need to convert the moles of aluminium to moles of oxygen using the chemical reaction:
1.875 moles Al * (3 moles O₂ / 4 moles Al) =

Whats is tge electron configuration of Ag2+ please answer asap..
Answer:
1s2 2s2 2p6 3s2 3p6 3d10 4s2 4p6 4d10
Explanation:
To write the configuration for the Silver and the Silver ion, first we need to write the electron configuration for just Silver (Ag). We first need to find the number of electrons for the Ag atom (there are 47 electrons) using the Periodic Table. When we write the configuration, we'll put all 47
Either way, the Silver electron configuration will be 1s2 2s2 2p6 3s2 3p6 3d10 4s2 4p6 4d10 5s1
Note that when writing the electron configuration for an atom like Ag and Ag+, the 4d is usually written before the 5s. Both of the configurations have the correct numbers of electrons in each orbital, it is just a matter of how the electronic configuration notation is written (see below for an explanation why).
For the Ag+, called the Silver ion, we remove one electron from 5s2 leaving us with:
1s2 2s2 2p6 3s2 3p6 3d10 4s2 4p6 4d10

Step 1: Gather materials and necessary information. a) You will collect the following information about your element: • Periodic table information including type of element, atomic number, atomic mass, number of protons, number of electrons, number of neutrons, period number, group number, and group name • Physical and chemical properties of the element • When, where, and by whom the element was discovered • Where the element is found and how it is obtained • Uses for the element and/or products made from the element • Images of the element b) Be sure to keep a list of your references so you can cite them later. c) Ask your teacher where you should save your presentation as you work on it. Your teacher may also have specific guidelines about the file name you should use.
Answer:
We hold these truths to be self-evident, that all men are created equal, that they are endowed by their Creator with certain unalienable Rights, that among these are Life, Liberty and the pursuit of Happiness.--That to secure these rights, Governments are instituted among Men, deriving their just powers from the consent of the governed, --That whenever any Form of Government becomes destructive of these ends, it is the Right of the People to alter or to abolish it, and to institute new Government, laying its foundation on such principles and organizing its powers in such form, as to them shall seem most likely to effect their Safety and Happiness. Prudence, indeed, will dictate that Governments long established should not be changed for light and transient causes; and accordingly all experience hath shewn, that mankind are more disposed to suffer, while evils are sufferable, than to right themselves by abolishing the forms to which they are accustomed. But when a long train of abuses and usurpations, pursuing invariably the same Object evinces a design to reduce them under absolute Despotism, it is their right, it is their duty, to throw off such Government, and to provide new Guards for their future security.--Such has been the patient sufferance of these Colonies; and such is now the necessity which constrains them to alter their former Systems of Government. The history of the present King of Great Britain is a history of repeated injuries and usurpations, all having in direct object the establishment of an absolute Tyranny over these States. To prove this, let Facts be submitted to a candid world.

A. Perspiration dries on a person's skin.When the sweat hits the air, the air makes it evaporate (this means it turns from a liquid to a vapor). As the sweat evaporates off your skin, you cool down. Sweat is a great cooling system, but if you're sweating a lot on a hot day or after playing hard you could be losing too much water through your skin.

in which of the following is number of neutrons correctly represented?
Answer:
²³⁸₉₂U has 146 neutrons
Explanation:
To know which option is correct, we shall determine the number of neutrons in each case. This can be obtained as follow:
For ²⁴₁₂Mg:
Mass number (A) = 24
Proton number (P) = 12
Neutron number (N) =?
A = P + N
24 = 12 + N
Collect like terms
N = 24 – 12
N = 12
Thus, there are 12 neutrons in ²⁴₁₂Mg
For ⁷⁵₃₃As:
Mass number (A) = 75
Proton number (P) = 33
Neutron number (N) =?
A = P + N
75 = 33 + N
Collect like terms
N = 75 – 33
N = 42
Thus, there are 42 neutrons in ⁷⁵₃₃As
For ¹⁹₉F:
Mass number (A) = 19
Proton number (P) = 9
Neutron number (N) =?
A = P + N
19 = 9 + N
Collect like terms
N = 19 – 9
N = 10
Thus, there are 10 neutrons in ¹⁹₉F.
For ²³⁸₉₂U:
Mass number (A) = 238
Proton number (P) = 92
Neutron number (N) =?
A = P + N
238 = 92 + N
Collect like terms
N = 238 – 92
N = 146
Thus, there are 146 neutrons in ²³⁸₉₂U
Considering the options and the illustration made above, Only ²³⁸₉₂U has the correct number of neutrons written along side.
