Explanation:
when an acid reacts with base and they cancel out defects of each other and as a product salt and water are produced this reaction is called a neutralization process
Answer:
According to the law of conservation of mass, the mass of the reacting substances is equal to the mass of the product formed during a reaction.
Explanation:
Answer:
0.156mol
Explanation:
Number of moles of a substance can be calculated from its mass by dividing its mass by molar mass i.e.
Number of moles (n) = mass/molar mass
Molar mass of PbCl4 is as follows, where Pb = 207.2g/mol, Cl = 35.5g/lol
PbCl4 = 207.2 + 35.5(4)
= 207.2 + 142
= 349.2g/mol
Using: mole = mass/molar mass
mole = 54.32 grams ÷ 349.2g/mol
mole = 0.1555
mole = 0.156mol
Answer:
The surface area increases, thus increasing the rate of reaction
Explanation:
When you use powder instead of solid metal, the surface area to volume ratio increases and so does the rate of reaction, because the chance of collisions between the particles increases as they can "touch" the metal more easily when it is looser, like powder.
