From 15 mol of Silver nitrate, the moles of silver chloride produced have been 15 mol. Thus, option B is correct.
The balanced chemical reaction for the synthesis of silver chloride has been:
From the balanced equation, since there has presence equal moles of silver nitrate and sodium chloride, the moles of silver chloride formed has been equivalent. Thus, 1 mole of silver nitrate gives 1 mole of silver chloride.
The moles of silver nitrate available are,
The moles of silver nitrate produced can be given as:
Thus, the moles of silver chloride produced have been 15 mol. Thus, option B is correct.

I would say it’s ‘laws are based on complex theories’.
A scientific law predicts the outcome, while a theory presents a possible explanation to why this outcome is. A law is based of a theory that supports the most data.
We will use this formula:
M1C1ΔT1 = M2C2ΔT2
when M1 mass of sample 1 = 31 g
C1 for water = 4.184
and ΔT1 = (Tf- 290)
and M2 of sample 2 = 47 g
C2 for water = 4.184
and ΔT2 = (340 - Tf)
so by substitution, we can get Tf (the final temperature):
31 g * 4.184 * ( Tf - 290 k ) = 47g * 4.184 * (340 - Tf)
∴Tf ( the final temperature) = 320 K
Explanation:
After calculating the density of the material we can tell if the object will sink or float without placing it in water by comparing their density.
- The density of water is given as 1kg/L
- If the density of the material is greater than the density of water, the material will sink.
- If the density of the material is less than the density of the water, it will float.
This way, comparing the density values of both substances can tell us whether they will float or sink.
