Molar mass of acetone 
is 58.07914 g/mol
Elements presents in acetone is
Carbon, Hydrogen and Oxygen
Atomic mass of carbon is = 12.01 u
Atomic mass of Hydrogen = 1..00 u
Atomic mass of Oxygen = 15.99 u
So molar mass of acetone will be
=
= ( 12.01 + 3*(1.00))*2 + 12.01 + 15.99
=58.07914 g/mol

#SPJ4
Equation is:
Ca(NO3)2 + Na3PO4 —> NaNO3 + Ca3(PO4)2
Balance it out
3Ca(NO3)2 + 2Na3PO4 —> 6NaNO3 + Ca3(PO4)2
You have 96.1g of Calcium Nitrate
Moles = Mass/Molar Mass
Molar mass of Calcium Nitrate is 164.088 g/mol
96.1g / 164.088 g/mol =0.586 moles
Mole ratio is 3:1
Therefore 0.586/3 moles of calcium phosphate
Moles x molar mass = mass
0.586/3 x 310.18 g/mol = 60.6~g roughly as theoretical yield
Answer:
D. Fire
Explanation:
Fire represents that if any acid or chemical reaction occurs, there may be chances of fire/explosion occurring. Wind, sunlight and dust doesn't matter when it comes to experimenting with chemicals.

Scientists use parallax to measure the distance between stars
Explanation:
covalent bond poor thermal conductivity
molecular compounds
metallic bond ductile
electron sea model
ionic bond crystalline
hard and brittle
Covalent compounds have the following properties:
- Gases and volatile liquids or low melting point solids
- Often insoluble in polar solvents
- Mainly non - conductors
- Have slow reactions
Metallic compounds:
- Have good malleability, ductility, electrical and thermal conductivity.
- A large sea of electron by jointly packed atoms.
- They are mostly in metals
- Accounts for the bulk of the physical properties displayed by metals
Ionic compounds:
- High melting and boiling point
- Soluble in polar liquids
- Conducts electricity in molten or aqueous forms.
- Mostly crystalline solids
- Usually hard and brittle
- Undergoes fast chemical reactions
