Can a negative number be expressed in scientific notation?
Yes, a negative number can be expressed in scientific notation. In scientific notation, a negative number is indicated by the negative sign (-) placed before the first significant digit. The number is then written in the form of a decimal number between 1 and 10, multiplied by a power of 10. For example, -3.2 x 10^-5 is a negative number expressed in scientific notation.

How do you find the square roots of fractions?
Square rootsTo find the square root of a number, you want to find some number that when multiplied by itself gives you the original number. In other words, to find the square root of 25, you want to find the number that when multiplied by itself gives you 25. The square root of 25, then, is 5. The symbol for the square root is . Following is a partial list of perfect (whole number) square roots.Note: If no sign (or a positive sign) is placed in front of the square root, the positive answer is required. No sign means that a positive is understood. Only if a negative sign is in front of the square root is the negative answer required.A fraction, or fractional number, is used to represent a part of a whole. Fractions consist of two numbers: a numerator (which is above the line) and a denominator(which is below the line).So to work out the square root of a fraction you find the square root of the numerator and put it above the square root of the denominator.
Given the F equals 8 G equals -3 and H equals 1 over 2 work out 4F - 5G - 2H?
You need to replace all the variables with the numbers specifed from above. When a letter and a number are placed side-by-side like you have in your equation that means to multiply. So, when you replace all the variabls with the correct numbers you have: =4(8)-5(-3)-2(1) So, when that is multiplied out you get: =32+15-2 You may see the I added a plus sign in front of the fifteen, when two negative numbers are multiplied the negative numbers become a positive number. When added together you get 45.

A negatively charged object is placed within a positive electric field. what happens to the object?
Electric Field between positive and negative charges. If the Electric Field in which both the positive and negative charges are present is stronger than the Electric Field between the two charges we are talking about, the the negative charge will move away from the positive charge in that positive direction of the field. If not, then the negative charge will get attracted to the positive charge and stay at the position of the positive charge. It will be pulled toward the source of the electric field. (Novanet)

Which element comes first in a chemical formula?
The order of compounds doesn't make a big difference, but the order for each of the elements within the compound does.Example:Ca + Cl2 -> CaCl2As you can see on the right side, Calcium is placed in front of Chlorine, because in this case Calcium is a cation (positive ion) and Chlorine is an anion (negative ion). In compounds like this, the cation (positive) element is placed first, and the anion (negative) element is placed second.The order on the left side doesn't really matter, seeing as there, Calcium and Chlorine are not bonded, although you will typically find that even though they are separate, they are still usually placed positive ion first and negative ion second, as shown.
Why molecular ion attraction exist in sodium chloride?
When an ionic compound is placed in water, it will split apart into either positive or negative ions. Sodium will form Na+ and chlorine will form Cl-. Positive and negative forces are attracted to each other, so the ions will be slightly pulled toward each other.
