It’s diagram because hydrogen has one proton and you’re not talking about ions so it needs another electron to stable itself
The best way (in my opinion) is to put it in a table or spreadsheet.
Answer:Avogadro's number is a very important relationship to remember: 1 mole = 6.022×1023 6.022 × 10 23 atoms, molecules, protons, etc. To convert from moles to atoms, multiply the molar amount by Avogadro's number. To convert from atoms to moles, divide the atom amount by Avogadro's number (or multiply by its reciprocal).
Explanation:
Answer:
The rock is heavier than water and when put into water it will sink.
Explanation:
Given data:
Mass of rock = 2.7 g
Volume = 1.1 cm³
Type of rock = ?
Solution:
From given data we can calculate the density of rock.
If the density of rock is higher than the density of water it means the rock is heavier than water.
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.
d = m/v
d = 2.7 g/ 1.1 cm³
d = 2.5 g/cm³
density of water is 1 g/cm³. The rock is heavier than water and when put into water it will sink.
Explanation:
a material system in which mass or energy can be lost to or gained from the environment.
