Can someone please help me out.....balance K plus H2SO4 arrow K2SO4 plus H2?
2 k + h2so4 = k2so4 + h2
How do you balance the equation K plus H2O yields H2 plus KOH?
Balanced :2 K + 2 H2O ----> 2 KOH + H2
What is the balance between k and h2so4?
It's K + H2SO4= K2SO4 +H2
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.

How do you balance K H2OKOH H2?
k+h2o>koh+h2
What is the balance between k and h2so4?
It's K + H2SO4= K2SO4 +H2
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.
How do you balance this equation SnO2 plus H2 --- Sn plus H2O?
Balanced equation: 2 H2 + O2 --> 2 H2O
Balanced equation for HCl plus K?
2K+2HCl-->2KCl+H2
How do you balance this equation K plus Br2--- KBR?
2 K + Br2 -> 2 Kbr
What is k eq for the reaction 2HCI(g) H2(g) plus CI2(g)?
For the reaction 2HCl(g) ==> H2(g) + Cl2(g), the Keq = [H2(g)][Cl2(g)]/[HCl(g)]^2
How do you balance K plus Br2 equals KBr?
Balanced:2 K + Br2 ----> 2 KBr
What is the coefficient for H20 when the following equation is balanced K plus H20 plus KOH plus H2?
2K + 2H2O --> 2KOH + H2 The balanced equation shows that there is a 2 in front of water.
ANSWERED How many g of potassium must react with H20 to produce 1.60 L of H2 at STP according to the following equation?
You need the balanced chemical reaction equation :------------------------------------------------------------------------2 K + 2 H2O ----. 2 KOH + H2moles H2 = n H2 = ( 1.60 L ) ( 1 mol H2 / 22.4 L H2 ) = 0.07143 moles H2moles K = n K = ( 0.07143 mol H2 ) ( 2 mol K / 1 mol H2 ) = 0.14286 moles Kmass K = m K = ( 0.14286 mol K ) ( 39.10 g K / mol K )mass K = m K = 5.56 g of potassium
