Out of the choices given, the part of the atom that forms chemical bonds are the outermost electrons. The correct answer is B.
Answer:
6.4g
Explanation:
32g of O2 produce 36g of H2O/5.70g of O2 produce x the answer is 6.4g
the answer is <span>Astatine is one period further than tellurium, meaning it has an extra shell. Therefore, the At atom will be bigger than the Te atom. </span>
Answer:
The cubic centimeter of boron is 2.
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:
mass of boron = 4.68 g
density of boron = 2.34 g/cm³
volume = ? (cm³)
Solution:
d = m/ v
v = m/d
v = 4.68 g/ 2.34 g /cm³
v = 2 cm³
Answer:
