Let 0< < .5 be some constant. consider running the partition subroutine on an array with no duplicate elements and with the pivot element chosen uniformly at random (as in quicksort and rselect). what is the probability that, after partitioning, both subarrays (elements to the left of the pivot, and elements to the right of the pivot) have size at least \alpha times that of the original array?
2. Same group
4. Same group
A = Hydrogen
B = Same Group
C = H2O
E = Compound = CH4 C:H :: 1:4
F = A
b)belong to same group
f)A has smallest atomic radius
ii.Elements A to G will belong to the same group of the periodic table since they contain the same number of electrons in their outermost shells or in other words, the valence electrons of both the elements are same.
iii. Since the element A is hydrogen, reaction will be:-
iv. Compound formed is CCl. Please refer to the attached image to see the formation of the same.
v. Element A (which is hydrogen) is likely to have the smallest atomic radius amongst all the elements in the group. This is because the atomic radius increases while moving down the group.
2.Group 18 elements (helium, neon, and argon are shown) have a full outer, or valence, shell.
3.The element with electronic configuration 2, 8 has a complete octet. Therefore, it is a noble gas. It will be found in group 18 with all the other noble gases.
answer:computer animation shows a cat movie in a straight line its height H metres above the ground is given by 8s - 3h = - 9 is the time in seconds after it starts moving in the same animation a mouse starts to move at same time as the cat and its movement is given by - 29s +10h = 16 find the height above the ground and the time when the cat meets the mouse (please answer this asap and no i wont mark you as brainliest for no reason) i need this answer in few time i need help in maths :(
a - magnesium; as the m shell is not completely filled hence 2+ is the valency of the element.
b - positive; as mg is a metal it will always form a positive ion
c - MgCl2
Electron affinity is the love for electron of an atom like if you placed an electron close to an atom so the tendency to atom to take it and loose energy is known as electron affinity. Electron gain enthalpy is the energy released or required to add an electron to an atom. It can pe + or - .
please Mark as brainliest and follow
the ratio of a , b and c = 3: 4: 6
