k = x y x = k/y
K= 18.666666
The value of k is 0
I am assuming that k is the constant of proportionality so that f = k*a*t/b2 = 3*4*6/22 = 18
10-k=5
The balanced equation is 2K + Br2 → 2KBr. This equation shows that two moles of potassium (2K) react with one mole of bromine (Br2) to produce two moles of potassium bromide (2KBr).
No, the chemical equation K + Br2 → 2KBr is balanced in terms of atoms but not charges. To balance it completely, you need to ensure that the charges are equal on both sides of the reaction.
The reaction 2KBr → 2K + Br2 is endothermic because heat must be supplied to break the bonds in potassium bromide (KBr) in order to form potassium (K) and bromine gas (Br2).
The balanced equation for the electrolysis of aqueous potassium bromide is: 2KBr(aq) + 2H2O(l) → 2KOH(aq) + Br2(g) + H2(g)
2 K + Br2 -> 2 Kbr
To balance the equation K + Br₂ → KBr, you need to make sure the number of atoms of each element is the same on both sides of the equation. To balance this equation, you need to put a coefficient of 2 in front of KBr. This way, you will have 2 potassium atoms, 2 bromine atoms, and 2 KBr molecules on both sides of the equation.
cl2 kbr---kcl br2i think u mean balance it right ^^;here u have cl2 kbr---kcl br2 so what u do iscl2 kbr---kcl br2cl=2 cl=1k=1 k=1br=1 br=2so u need to balance that ...u need to add (2) to kbr and add (2) to kcl so that u have Cl2 (2)KBr ----(2)KCl Br2 hope that will help ^^ so now u have them balanced by adding 2 in front of kbr that means u r multiplying them by 2 so that K is going to be k=2 and br is going to be br=2 and u r doing that because there is br =1 on one side and the other side there is br=2 and u need them balanced. By adding 2 to kcl means that the other k now is k=2 so as cl. hope its helpful ^____~
The reaction of potassium bromide with chlorine is known as a displacement reaction, where the more reactive chlorine displaces the less reactive bromide to form potassium chloride and elemental bromine.
1:2 mole ratio of potassium to bromine in the balanced chemical equation, so the limiting reactant is potassium since it produces fewer moles of product. 2.92 moles of potassium can produce 1.46 moles of potassium bromide.
KBrO3 and KBr do not react with each other because they have same cation K+, but separately they react with H2SO4. 2KBrO3 + H2SO4 -------> K2SO4 + 2HBrO3 2KBr + H2SO4 ----------> K2SO4 + 2HBr
There are two atoms in one molecule KBr. One atom of potassium (K) and one atom of bromine (Br).
The balanced equation for the reaction between LiOH (lithium hydroxide) and K (potassium) is: LiOH + K -> LiOH + KOH
