Answer:
ρ = 1.08 g/cm³
Explanation:
Step 1: Given data
Mass of the substance (m): 21.112 g
Volume of the substance (V): 19.5 cm³
Step 2: Calculate the density of the substance
The density (ρ) of a substance is equal to its mass divided by its volume.
ρ = m / V
ρ = 21.112 g / 19.5 cm³
ρ = 1.08 g/cm³
The density of the substance is 1.08 g/cm³.
Answer:
Arsenic (As) anion has -‐3 charge, but also forms cations with +3 or +5 charge.
Explanation:
A solution is a mixture (solvent + solute) of 2 or more elements, for example chocolate milk.
A solvent is the base of the solution which dissovles a solute, for example milk.
A solute is what is dossolved by the solvent, for example chocolate powder.
Answer:
Osmosis
Explanation:
Water is very essential for the body. When we drink water, our blood cells absorbs water from the body. This happen by a process called as osmosis process. Osmosis is type of diffusion process.
Water along with oxygen and carbon dioxide are some of the simple molecules that moves into the blood cell. Osmosis is the process by which water molecules passes into the cell bodies through its semi permeable membrane.
Answer:
MgCl2 (s) + Li2CO3 (s) ==> MgCO3 (s) + 2LiCl (aq)
Double Replacement
Explanation:
MgCl2 (s) + Li2CO3 (s) ==> MgCO3 (s) + 2LiCl (aq)
Double Replacement
Halogens are Soluble
Carbonates are Insoluble
This reaction DOES take place.
