What is an example of a diatomic molecule?
Common diatomic molecules can be remembered using the anagram HOFBrINCl (Hydrogen, Oxygen, Fluorine, Bromine, Iodine, Nitrogen, Chlorine). Diatomic molecules don't have to be composed of only one type of element (homonuclear). Carbon Monoxide (CO) is also an example of a diatomic molecule.
Which group of the periodic table contains elements that exist as diatomic molecules?
There is a firm IUPAC convention about the numbering of the groups in the periodic table. There does not appear to be one about numbering the periods. Sometimes the first row, containing only H and He is regarded as period 1, or sometimes as period Zero. I will presume that your question was using the first numbering, and frame an answer with respect to elements Na --> Ar Most of the lighter elements in the periodic table will form X2 gases. The ones that will not are (i) Those that have an exactly filled subshell in the electron structure of their atom, and (ii) Those that do not have significant vapour pressure below temperatures where molecules cannot exist, and all matter is monatomic. Na & Cl will form vapours of Na2 and Cl2 respectively. Al & Si do not evaporate until very high temperatures, but low enough that some diatomic molecules can be found in what are largely monatomic vapours. P & S form vapours of P4 and S8 respectively at low temperatures around their respective boiling points, but in each of these cases there is a higher temperature range where P2 or S2 molecules can be observed. Mg and Ar do not form diatomic molecules in the gas (or any other) phase.
How do you find molarity with mL?
You convert the mL to liters and use the equation: M=moles/L Using that you should be able to get the molarity....
What is a sentence using the words elements?
In science class we learn about elements.
What is an example of a molecular formula for a diatomic molecule?
You can easily remember the formulas of the homonuclear diatomic elements using the saying Never Have Fear Of Ice Cold Beer. This stands for N2, H2, F2, O2, I2, Cl2, and Br2.
What is a word equation and a formula equation?
A word equation is where you describe a reaction using the chemicals by their names Eg. Hydrogen+Oxygen>Water A formula/symbol equation is where you use each chemical's formula (which is a group of the elements it consists of) Eg. H2+O2>H2O (you should use small letters for the numbers after the element)
How are elements represented in a chemical equation?
It is represented by element symbols, like using Na to refer to sodium.
What is a reactant equation using Tantalum?
It burns to give T2O5 - that should be an easy equation to write.....

Should the number that multiplies each side of the equation be nonzero when using multiplication property?
Yes, it should be non-zero; if you multiply both sides by zero you wipe out the equation.
What is the similarity between an ordinary chemical equation and a nuclear equation?
A chemical equation puts down on the LHS the chemicals mixed together and on the RHS the results. A nuclear equation puts on the LHS the target element, with an incident particle if relevant, and on the RHS the results. But in a chemical process the constituent elements must balance on each side, whereas with a nuclear change the elements can be converted to other elements.
How can you represent a proportional relationship using an equation?
You cannot represent a proportional relationship using an equation.

What is equadtratic equation?
A quadratic equation normally has 2 solutions and can be solved by using the quadratic equation formula.
How do you solve for x using a quadratic equation?
For an equation of the form ax² + bx + c = 0 you can find the values of x that will satisfy the equation using the quadratic equation: x = [-b ± √(b² - 4ac)]/2a
