This would be the downward movement of water. It begins flowing and continues in a downward movement moving throughout,
Answer:
8 lithium atoms and 4 oxygen atoms
Based on Heisenberg's uncertainty principle, the position and velocity of a particle cannot be determined simultaneously with accuracy.
In other words, Heisenberg's uncertainty principle states that the more accurately we know the position of a particle the less accurately we can know its velocity. Mathematically it is given as:
Δx.mΔv >= h/2π
where: Δx = uncertainty in position
m = mass
Δv = uncertainty in velocity
h = plancks constant
Answer:
Opposite poles of attract each other and make bonds.
Explanation:
Those compounds are soluble in water which have polar nature means that make poles with other atoms while on the other hand, those compounds which doesn't have polar nature are dissolve in non-polar solvent. The polar nature of compounds is due to their difference in electronegativities so in polar compounds opposite poles attract one another and make bonding with each other.
Answer:
41.56 g
Explanation:
Given data:
Mass of NH₄Cl = 15.50 g
Actual yield of AgCl = 35.50 g
Theoretical yield of AgCl = ?
Solution:
Chemical equation:
NH₄Cl + AgNO₃ → AgCl + NH₄NO₃
Number of moles of NH₄Cl:
Number of moles = mass/ molar mass
Number of moles = 15.50 g/ 53.491 g/mol
Number of moles = 0.29 mol
Now we will compare the moles of NH₄Cl with AgCl .
NH₄Cl : AgCl
1 : 1
0.29 : 0.29
Theoretical yield of AgCl:
Mass = number of moles × molar mass
Mass = 0.29 mol ×143.32 g/mol
Mass = 41.56 g
