What is k equals xy for x?
k = x y x = k/y
3k-5 equals 61 what is the value of k?
K= 18.666666
When f varies jointly as a and t and inversely as the square of b what is the answer when determining f when k equals 3 a equals 4 t equals 6 and b equals 2?
I am assuming that k is the constant of proportionality so that f = k*a*t/b2 = 3*4*6/22 = 18
What is 10 less than a number k equals 5?
10-k=5
Suppose y varies inversely with X use the information to find K and choose the equation of variation. X equals 7 and y equals 3?
xy = K so K = 21
What is the balance of K Br2 2KBr?
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).
Is K Br2 2KBr balanced?
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.
Is the reaction 2KBr - 2K plus Br2 endothermic or exothermic?
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).
What is the balanced equation for the electrolysis of aqueous potassium bromide?
The balanced equation for the electrolysis of aqueous potassium bromide is: 2KBr(aq) + 2H2O(l) → 2KOH(aq) + Br2(g) + H2(g)
How do you balance K plus Br2 equals 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.
How do you balance this equation K plus Br2--- KBR?
2 K + Br2 -> 2 Kbr
What is the predicted yield for Cl2 KBr--KCl Br2?
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 ^____~
What is the name of the reaction of potassium bromide with chlorine?
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.
How many moles of potassium bromide can be produced from the reaction of 2.92 moles of potassium with 1.78 moles of bromine gas?
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.
What is the product formed by the reaction ''KBrO3 plus KBr plus H2SO4''?
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
How many atoms are in 2KBr?
There are two atoms in one molecule KBr. One atom of potassium (K) and one atom of bromine (Br).
What is the balanced equation of lioh plus k?
The balanced equation for the reaction between LiOH (lithium hydroxide) and K (potassium) is: LiOH + K -> LiOH + KOH
