This answer is true a rain gauge can measure solid and liquid precipitation
If the forward reaction goes close to completion and has a high yield, that means the concentration of products will be higher than the concentration of reactants.
<span>So if the concentration of products is higher, Kc (equilibrium constant) will be greater than 1.

Recall the calculation for the equilibrium constant for reaction. Picture below might help you.</span>
I would say is b. The answer
It tells you how many atoms it has, how many protons it contains and the number of electrons.
Answer:
2
Explanation:
Mass of water molecule = mass of hydrated salt - mass of anhydrous salt
Mass of water molecule = 5.00 - 4.26 = 0.74g of water molecule.
Number of moles = mass / molarmass
Molar mass of water = 18.015g/mol
No. of moles of water = 0.74 / 18.015 = 0.0411 moles.
Mass of BaCl2 present =?
1 mole of BaCl2 = 208.23 g
X mole of BaCl2 = 4.26 g
X = (4.26 * 1) / 208.23
X = 0.020
0.020 moles is present in 4.26g of BaCl2
Mole ratio between water and BaCl2 =
0.0411 / 0.020 = 2
Therefore 2 molecules of water is present the hydrated salt.
