Alkali metals (like Na and K) and halogens (like Cl and Br) have the general ionic formula format XY (X+ and Y- in solution)
It depends upon what elements X and Y are, but under certain circumstances, it could yield compound XY.
Wow! What do you mean "when elements react", specifically, which elements? Here are the basic reactions though: Combustion:fuel + oxygen -> oxides + energy Synthesis: A + B -> AB Decomposition: AB -> A + B Single Displacement:one element replaces another from a compound: Z + AB -> ZB + A Double Displacement: Elements in different compounds exchange places: AB + XY -> AY + XB ***Smartiiz***
the genotype for a male is XY thank you, Allyson
xy chromosomes mostly fall on male gender.
If two fraternal twins have the XY sex chromosomes, they will be male.
The general multiplicative inverse of xy is y-1x-1. The additive inverse is -xy
xx + xy = baby
For all whole numbers X = -2, [infinity to - infinity]
So far you know that: x=-8 xy=1 so xy means x times y. If you split xy. y=1/x or y=1/-8 1/-8= -0.125 You can find out that this is correct with the formula xy=1 because -0.125 x -8 is 1.
There is no specific "formula." If you want the area of a rhombus, that is just A = bh/2 or (1/2)xy where x and y are the lengths of the diagonals.
xy - xy = 0
xy + xy = 2xy
180 degrees in the plane perpendicular to the xy plane. In general, no rotation in the (x, y) plane will take it to (-x, y) unless x = y (or -y) and, in that case it is a 270 degree clockwise rotation.
Matrices have two diagonals: main diagonal and anti-diagonal. The main diagonal runs from top-left to bottom-right. For square matrix A: // main diagonal: for (size_t xy=0; xy<A.size(); ++xy) cin >> A[xy][xy]; // anti-diagonal for (size_t x = A.size()-1, y=0; y<A.size(); --x; ++y cin >> A[x][y];

The right answer is "XY CHART", not Pie Chart, because when it comes to the fact, "one or more data elements are relate to another data element" can only be seen & proven in XY CHART ONLY.
