Can Mastering Chemistry detect cheating?
Can Mastering Chemistry detect cheating?
It’s definitely fake-able, but most of my students don’t put that much effort into cheating. You can consider timing the exam with less time to discourage using other sources as much as possible.

How do you enter chemical equations in mastering chemistry?
Enter chemical equation, formula or expression answers
- Use + (plus sign) in superscripts or in the baseline.
- Use – (minus sign) in superscripts only.
How do you know if a chemical formula is incorrect?
To determine the correct subscripts in a chemical formula, you have to solve how many atoms you need to balance the charge. For example if I had the compound Calcium Fluoride I would look at the periodic table and see that Calcium’s ionic formula is Ca2+ .
How do you write ions in mastering chemistry?
- To indicate a POSITIVE ion: Enter the plus sign (+) after the carat (for superscript).
- To indicate a NEGATIVE ion: Enter a minus sign (-) after the carat (for superscript).
- For an ionic molecule or formula: The superscript indicating the charge must come at the very END of the molecular formula.
How do you write atomic notation?
The atomic number is written as a subscript on the left of the element symbol, the mass number is written as a superscript on the left of the element symbol, and the ionic charge, if any, appears as a superscript on the right side of the element symbol.
How do I put chemistry on my keyboard?
Select Settings, then General. Select Keyboard, then Keyboards. Select Add New Keyboard.
How do you write chemical symbols?
With the cursor at the insertion point where you want the symbol to appear, type 21cc, then press ALT and X simultaneously. If you have the Lucida Sans Unicode font available, this will type the equilibrium symbol without going to the insert symbol menu.
What is the double arrow in chemistry?
Double-headed arrows are used to represent equivalence between resonance structures. Two-way double half arrows are represent a reaction that can go forward or reverse. If one of the half arrows is longer than the other it means that the reaction pathway favors that direction with the longer arrow.
How do you write so2?
Superscript in Word
- Or you can use the keyboard shortcut: press Ctrl and Shift, then hit +.
- A subscript is a character, symbol or number set slightly below the normal line of text.
- If you need a subscript in you Word document, here’s how to do it.
- Click where you’d like the subscript to appear.
What is an example of a chemical symbol?
A chemical symbol is a one- or two-letter designation of an element. Some examples of chemical symbols are O for oxygen, Zn for zinc, and Fe for iron. The first letter of a symbol is always capitalized. If the symbol contains two letters, the second letter is lower case.
What are the three rules for writing chemical symbols?
If the chemical symbol has two letters the first letter is always capitalized and the second letter is written in lowercase. For chemical symbols that consist of one letter, that letter is always capitalized. For example, C represents carbon, Ca for calcium, O for oxygen.
Is carbon malleable yes or no?
Physical State: Most of the non-metals exist in two of the three states of matter at room temperature: gases (oxygen) and solids (carbon). Non-Malleable and Ductile: Non-metals are very brittle, and cannot be rolled into wires or pounded into sheets. Conduction: They are poor conductors of heat and electricity.
