Im pretty sure its this but im like 90% sure. Let me know what the answer is once its graded.
Answer:
Protons: C12= 12 Protons, C13=12 Protons and C14=12 Protons
#electrons= 12+0=12 electrons in all Carbon atoms Neutron: C12=0, C13= -1, C14= -2
Atomic mass of C12, C13 and C14= 12
C12, C13, and C14 are called “ISOTOPES”
Explanation:
The ksp = 4.87 × 10^-17
Therefore; 4.87 ×10^-17 = [Fe2+][OH-]^2 = (X)(2X)^2 = 4X^3
Hence;
4x^3 =4.87 × 10^-17
x = 2.30 × 10^-6 M
therefore the molarity is 2.3 ×10^-6 M
Thus;
The mass of Fe(OH)2 in 100 ml of water, will be given by:
= 2.30 × 10^-6 mol/L = 2.3 ×× 10^-5 mole/100 mL
= 89.86 g/mol × 2.3 × 10^-6 × 0.100 = 2.07 × 10^-5 g
= 2.07 × 10^-5 g
= 2.07 × 10^-5 g
A central silicon atom is bonded to two chlorine atoms and two methyl groups
Explanation:
Enantiomers are chiral molecules that are mirror images of each other but cannot be superimposed on each other. In this case, a silicon atom, bonded to two chlorine atoms and two methyl groups, when its bonds are rotated, can appear like mirror images of the previous molecule.
The answer is A) Sodium is an Alkali metal and is in group IA with an ionic charge of +1. While chlorine, Cl, is a halogen and is in group VIIA with a charge of -1. These will form NaCl(s).
