If you are wanting the equation to be balanced it would be: P4 + 6Cl2 → 4PCl3
Physical change because water is not a gas or change . you can see through it.
Answer/explanation :
To calculate the number of mass, we use this formula
Number of mole = mass / molar mass
Since we are given the number of mole
Number of mole = 2.60mol
Mass = ?g
Molar mass of Li = 6.941g/mol
2.60mol = mass / 6.941 g/mol
Mass = 2.60 * 6.941
= 18.0466g
Therefore, the number of mass is 18.0466g
Explanation: For solid or cold objects, (like ice), the particles are close together and not moving. For liquids, (like water), the particles are moving freely and limited energy depending on if it is warm or not. For gas, the particles are way spread out, and moving fast.
