Prove that the two consecutive positive integer is divisible by 2?
There is something missing from your question: what about the two consecutive integers? Is the proof required that one of them is divisible by 2? Or that their product is (which amounts to the same thing)? Showing that one of two consecutive number is divisible by 2: Suppose your two numbers are n and (n+1). If n is divisible by 2, ie n = 2k, the result is shown. Otherwise assume n is not divisible by 2. In this case n = 2m+1. Then: (n+1) = ((2m+1)+1) = 2m + 2 = 2(m+1) which is a multiple of 2 and so divisible by 2. QED. Showing that exactly one of two consecutive integers is divisible by two is shown above with the addition to the first part: "as (n+1) = 2k+1 is not divisible by two and so only n is divisible by 2." To show the product is divisible by 2, show either n is divisible by 2 or (n+1) is as above, then the result follows as one of n and (n+1) is divisible by 2 and so their product is.
What two numbers do you have to add to make the word hell on your calculator?
Add any two numbers that add to 1134 or 7734. So pick any number, say n. Calculate the second number as 1134 - n or 7734 - n. Add these two.
How many faces and edges of pyramid?
one face eight edges and five corners * * * * * The above answer is complete rubbish. A pyramid is a generic term for three dimensional shapes which consist of an n-sided polygon (n > 2) as base and n triangular faces meeting at an apex above the base. For any integer n>2, a pryramid with an n-polygonal base has: n + 1 faces n + 1 vertices and 2n edges.
True or false- every odd whole number can be written as the difference of two squares?
it's true for every odd number greater than 1, because the difference between the squares of two consecutive numbers is always a unique odd number eg: 42 - 32 = 7, 52 - 42 = 9 etc etc. Every odd number, call it x, is the sum of two consecutive numbers, call them n and n + 1. To find the two squares that differ by x, all you need do is add n and n + 1. Eg the squares which differ by 101 are 502 and 512 (2500 and 2601). Similarly to find the difference between the squares of two successive numbers, just add the two numbers, see examples above. Proof: x = n + (n + 1) (n + 1)2 - n2 = n2 + 2n + 1 - n2 = 2n + 1 = n + (n +1) = x

What is the Lewis Structure for SeCN-?
.. .. .. :Cl - Se - Cl: .. .. .. There are two dots above the Cl, Se, and other Cl. There are also two dots below the Cl, Se, and other Cl. There are two dots to the left of Cl, and two dots to the right of the other Cl. The dash (-) represents two dots. So, there are a total of 20 electrons. Se has 6, and each chlorine has 7. 6 + 7(2) = 20

How the triangular pattern number works?
First, draw a dot. Below that, draw two dots. Then, 3 dots below it and so on. Here, you should see the pattern of the triangular number, which is the sum of consecutive integers starting at 1. The terms of that pattern are 1, 3, 6, 10, 15, ....n(1 + n)/2 where n is the total number of dots for the pattern.
What type of dot structure does nitrogen have?
If you are talking about the Lewis Dot Diagram then N2 would have 5 dots around each of the letter N's, so that there would be 6 dots total (triple bond) between the two N's and a pair of dots behind each N. :N:::N: Each N can now 'feel' 8 electrons completing the octet rule.
Write the Lewis structure for OCN?
Two structures (resonance), one with a triple bond between C and N, and a single bond between O and C, with one lone pair on the N and three lone pairs on the O. Second structure has two double bonds between both the C and N and O and C, with two lone pairs on both N and O. Charge is -1, indicated by brackets. Source: Chemistry, Zumdahl, 3rd Ed.
How do you make the spanish sqiggly line above the n on iPhone?
Hold the finger onto n until the variations of n appear.
How do figure out what numbers up to 100 make up a square?
Start at 1. That is a Square. Add 3 to make 4 (another square) . Keep on adding successive odd numbers, and each time you will have another square. To understand this think of 9 dots arranged in 3 rows ( a 3 x 3 square). To make the next square you have to add n dots along the top, n dots down the side, and 1 extra in the corner. Thats 2n+1 dots. You originally had n2 . Now you have (n+1)2 simply by adding the odd number 2n+1. Recall that (n+1)2 = n2+2n+1. This is the basis for an old method for finding square roots.
Lewis structure for dinitrogen tetroxide?
The Lewis structure for dinitrogen tetroxide (N2O4) shows two nitrogen atoms double-bonded to each other with an oxygen atom single-bonded to each nitrogen atom, and the remaining two oxygen atoms are located on opposite sides of the central N-N bond. The structure is N≡N-O-O-N≡N.
What is the Lewis dot diagram for Dinitrogen trioxide?
The Lewis dot structure of a nitrogen atom would be the capitol letter N with the five valence electrons represented by two dots above it, one to the left right and bottom of it. .. . N . . However, nitrogen gas is usually found in diatomic form as N2 and the Lewis diagram would look like this: :N:::N: with each N getting to share three pairs of dots, representing the bonds. In the corresponding molecular structural formula, N≡N, the two unbonded pairs of electrons are often left out.
Let n stand for any figure number Use n to tell how many dots there would be in the nth figure?
N x N + 1 = answer
How do you know how many dots there are for each element?
If by dots you mean electrons, all you need to know is the atomic number and know that: n=1 has a max of 2 n=2 has a max of 8 n=3 has a max of 18 And so on and so forth.
