Answer:
A chemical equation can be described as a symbolic representation of a chemical reaction. It can be written in the form of words or symbols.
The following chemical reaction can be completed as :
Na2SO4·10H2O + 2C = Na2S + 10H2O + 2CO2
Sodium Sulfate Decahydrate + Diamond = Sodium Sulfide + Water + Carbon Dioxide
The products of the reaction are:
- Sodium Sulfide (Na2S)
- Water (H2O)
Simply put, density is how tightly “stuff” is packed into a defined space.
For example, a suitcase jam-packed with clothes and souvenirs has a high density, while the same suitcase containing two pairs of underwear has low density. Size-wise, both suitcases look the same, but their density depends on the relationship between their mass and volume.
Mass is the amount of matter in an object.
Volume is the amount of space that an object takes up in three dimensions.
Density is calculated using the following equation: Density = mass/volume or D = m/v.
If something is heavy for its size, it has a high density. If an object is light for its size it has a low density.
The relative densities of an object and the liquid it is placed in determine whether that object will sink or float.
Answer:phosphates are insoluble in water
Explanation:
The atomic mass on the periodic table represents the sum of number of protons and number of neutrons.
Atomic mass = Number of protons + number of neutrons
