Not an acid base reaction but a powdered one the acid doesn’t exist its the baking powder
<span>Density is a physical
property which describes the mass of a substance per unit of volume of the
substance. It is expressed as Density = m / V and it has units like g/cm^3. To determine the diameter of the cylinder, we use the definition of density. We first calculate the volume from density as follows:
Density = mass / volume
Volume = mass / density
Volume = 310 g / 2.33 g/cm^3
Volume = 133.15 cm^3
Volume of a cylinder is equal to the product of pi, square of the radius of the base and the height. It is expressed as follows:
Volume = </span>πr^2h
We calculate for the radius, r, which is equal to one half the diameter.
r = √(Volume / πh)
r = √133.15 / π(46)
r = 0.9595 cm
Diameter = 2r = 2 (0.9595) = 1.92 cm
Answer:
<u><em>Bullys.</em></u>
Explanation:
<h3>{: I took the quiz in K12 and the first time I put <u><em>Pencils</em></u> but it said it was wrong and the right one is <em>Bullys. I hope this helps! :]</em></h3>
Answer:
5.72 g ( 1 mol / 180.16 g ) ( 6.022 x 10^23 molecules / mole ) = 1.90x10^23 molecules
The balanced chemical equation is Pb(NO3)2+ 2KI produces PbI2 + 2K(NO)3
.4 L of KI × (.375 mol/L of KI) × (1 mol of PbI2 / 2 mol of KI) × (461 g of PbI2/1 mol of PbI2)
=34. 6 g of PbI2 precipitate.
