The enthalpy change is negative.
The other statements are false because:
Can take place without a catalyst
Energy is given out to the surroundings.
Kinetic energy of products is higher.
Mass = moles x Mr
So in this case the moles =1
And the Mr equals =11
So you would do - 11x1= 11grams
Answer:hey man am sorry but have you tried to search it up
Explanation:
Answer:
The pOH is 4, 44 and the solution is basic.
Explanation:
The pOH is a measure of the concentration of OH (hydroxyl) ions in the solution.
The pOH is calculated as :
pOH = -log (OH-)= -log (3.67 x 10-5 )= 4, 44. In this case, the solution is basic.
The p0H scale ranges from values of 0 to 14 (less than 7.0 is basic and greater than 7.0 is acidic, a pH = 7.0 is neutral)
<u>Answer:</u> The reaction for the 
value of lead phosphate is given below and the value of solubility product for the same is 
<u>Explanation:</u>
Solubility product is defined as the product of concentration of ions present in a solution each raised to the power its stoichiometric ratio. It is expressed as
The chemical formula of lead phosphate is 
The equation for the hydration of the lead phosphate is given as:
The solubility product of lead phosphate is . This means that it is highly insoluble in water as the solubility product is very very low.
Hence, the reaction for the value of lead phosphate is given above and the value of solubility product for the same is
