Al(NO₃)₃(aq) → Al³⁺(aq) + 3NO₃⁻(aq)
c(NO₃⁻)=3c(Al(NO₃)₃)
c(NO₃⁻)=3*0.600 mol/L=1.800 mol/l
Answer: Thermal energy is the _average kinetic energy of the particles in an object____ and internal energy is the ___total energy of particles in an object__.
Explanation:
Answer:
A. Glucose
Explanation:
Glucose is a monomer and not a polymer. So, option (A) is not a polymer.
Explanation:
Given reaction:
¹⁰⁸₅₃I → ⁴₂He + ?
An alpha particle decay requires that the mass number decreases by 4 and atomic number decreases by 2.
This reaction is called nuclear fission;
The unknown compound, say Y, will have mass number and atomic number shown below;
¹⁰⁸₅₃I → ⁴₂He + ᵃₙY
Mass number; 108 = 4 + a
a = 104
Atomic number ;
53 = 2 + n
n = 51
Y will be ¹⁰⁴₅₁Y
The atomic number of the new element is 51; so, it is antimony.
¹⁰⁴₅₁Sb
8.908 G/cm^3 is the density of a nickel
