What is the density of an 820 g sample of pure silicon occupying a 350 cm3 container
vodka [1.7K]

Answer:

2.343 g/ cm³

Explanation:

Density:

Density is equal to the mass of substance divided by its volume.

Units:

SI unit of density is Kg/m3.

Other units are given below,

g/cm3, g/mL , kg/L

Formula:

D=m/v

D= density

m=mass

V=volume

Symbol:

The symbol used for density is called rho. It is represented by ρ. However letter D can also be used to represent the density.

Given data:

density = ?

volume= 350 cm³

mass= 820 g

Now we will put the values in the formula,

d= m/v

d= 820 g/ 350 cm³

d= 2.343 g/ cm³

The density of silicon is 2.343 g/ cm³

What is the name of the isotope produced when Californium-251 emits an alpha particle?
Charra [1.4K]
<h3>Answer:</h3>

                 Curium-247 <em>i.e.</em> ²⁴⁷₉₆Cm

<h3>Explanation:</h3>

Alpha decay is given by following general equation,

                              ᵃₓA    →    ⁴₂He  +  ᵃ⁻⁴ₓ₋₂B

Where;

           A  =  Parent Isotope

           B  =  Daughter Isotope

           ᵃ  =  Mass Number

           ₓ  =  Atomic Number

Californium-251 is the parent isotope in our case and it has 98 protons (atomic number) and is given as,

                                                 ²⁵¹₉₈Cf

The alpha decay reaction of Californium-251 will be as,

                               ²⁵¹₉₈Cf     →     ⁴₂He  +  ²⁴⁷₉₆B

The symbol for B with atomic number 96 was found to be the atom of Curium (Cm) by inspecting periodic table. Hence, the final equation is as follow,

                               ²⁵¹₉₈Cf     →     ⁴₂He  +  ²⁴⁷₉₆Cm
