What is RB plus H2o?
2Rb(s) + 2H2O(l) --> 2RbOH(aq) + H2(g)
Two metallic wires A and B are connected in parallel combinationWire A has length 'l' and radius 'r'Wire B has length '2l' and radius '2r'Commute the ratio of total resistance of parallel combination?
FOR WIRE A , RA = rho L/A = rho L/pie* r square -equation 1 RB = rho 2L/pie(2r)square = rho 2L/4 pie*r square =rho L/2 pie * r square -equation 2 RA/RB = rho L/pie * r square * 2 pie *r square/rho L RA/RB = 2 RA = 2RB , RB = RA/2 1/Rp = 1/RA + 1/RB =1/RA +1/RB 1/Rp = 3/RA Rp/RA = 1/3 Hence the ratio is 1:3
How do you make a the subject of r equals ab divided by a plus b?
Are you asking to have that equation solved for 'a' ?r = ab / (a + b)Multiply each side by (a + b) . . . ra + rb = abSubtract 'ra' from each side. . . . rb = ab - raFactor the right side . . . . . . . . . rb = a (b - r)Divide each side by (b - r) . . . . . a = rb / (b - r)
37 (Rb)?
Rubidium
What shipping company using RB after 9 digits then CN?
It might be China Post Registered Mail.
Which of the following has the smallest radius is K plus Rb Rb plus K?
K+
Which element is the largest K Rb Na Li?
Rb (rubidium) is the largest element among K (potassium), Rb (rubidium), Na (sodium), and Li (lithium). This is because as you move down a group in the periodic table, the atomic size increases due to the addition of more electron shells.
What element has the smallest first ionization energy of Li Na Rb and K?
Rb
What species has the smallest atomic radius between Kor Mg orRb or Ca?
The species with the smallest atomic radius among K, Mg, Rb, and Ca is Rb (Rubidium). This is because atomic radius tends to decrease across a period from left to right in the periodic table, and Rb is located towards the right side of this group of elements.
Which has the smallest radius K Rb K Rb?
Rb+ has a smaller radius than K+ due to increased effective nuclear charge in rubidium. Therefore, K+ has a smaller radius than Rb.
What period is the element rb in the periodic table?
The element Rb (Rubidium) is in period 5 of the periodic table.
What atomic radius is larger Rb or Sr?
The atomic radius of Sr (Strontium) is larger than that of Rb (Rubidium). This is because atomic radius generally increases down a group in the periodic table, and Sr is located below Rb in the same group.
What is the smallest to largest Li Li Rb Cs?
Smallest to largest is going down the group 1. I.e. Li is smallest<Rb<Cs
How many protons does the element RB have?
The element RB, which is rubidium, has 37 protons.
Which element has the smallest first ionization energy Na K Rb Li?
The element with the smallest first ionization energy is Francium, as it is located in Group 1 of the periodic table and has the largest atomic size. Among the elements listed, lithium (Li) would have the smallest first ionization energy as it is closer to the upper right of the periodic table compared to sodium (Na), potassium (K), and rubidium (Rb).
What is the atomic radius of Rb?
The atomic radius of rubidium (Rb) is approximately 248 picometers. This is the distance from the nucleus to the outermost electron shell in a rubidium atom.
What element does Rb stand for?
Rubidium.
