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).
How many atoms are there in Fe2O3?
Five atoms
How does a number of H Atoms in a carbohydrate compared to the number of oxygen atoms?
It depends on how many hydrogens are there and how many oxygen atoms there are.
Which of these are examples of decomposition reactions 1 2no n2 o2 2 2k br2 2kbr 3 h2 cl2 2hcl 4 2pocl3 2pcl3 o2?
1 (fully) and 4 (only partial) are decomposition reactions.
How many atoms of in a CO2 molecule?
2 atoms
Is 2K plus Br2 and 2KBr balanced?
The equation 2K + Br2 -> 2KBr is balanced as there are equal numbers of atoms of each element on both sides of the reaction.
Is K Br2 equals 2KBr balanced?
No. No. No. No.
What is the balanced equation form of potassium bromide and chlorine to form potassium chloride and bromine?
2KBr + Cl2 ----> 2KCl + Br2
What is the balance of K Br2 2KBr?
You need to have values for K, Br2 and 2KBr in order to find out the balance. For example, if you had the values as H2 + O2 = H20 the balanced chemical equation would be 10 H2 = H20.
What is the equation for the reaction between bromine and potassium chloride?
The equation for the reaction between bromine and potassium chloride is: 2KCl + Br2 -> 2KBr + Cl2
Is K Br2 2KBr balanced?
Yes, the equation K + Br2 = KBr is a balanced chemical equation. For example, 2 K + Br2 = 2 KBr is one and another balance chemical equation is Fe + Cl2 = FeCl3.
Potassium mangnate to potassium per mangnate?
2K2MnO4 + Br2 ----> 2KMnO4 + 2KBr
What is the name of 2KBr?
The name of 2KBr is potassium bromide. It consists of two potassium (K) ions and two bromide (Br) ions, reflecting its chemical formula of KBr. Potassium bromide is commonly used in various applications, including pharmaceuticals and photography.
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).
When the following equation is balanced using the smallest possible integers what is the number in front of the underlined substance in each case Br2 Kl-l2 KBr?
The balanced equation is: Br2 + 2Kl -> 2KBr + I2. This means there is a 2 in front of the underlined substance, KI.
What happen when KBr is heated with conc H2So4 acid?
Balanced equation formed: H2SO4 + 2KBr ==> 2HBr + K2SO4
