Answer:
Observe how the force of gravity is directly proportional to the product of the two masses and inversely proportional to the square of the distance of separation.
Explanation:
I think im not sure
<span>The mass of one mole of sodium bicarbonate (aka NaHCO3) is equal to 1 * 22.99g/mol + 1 * 1.00g/mol + 1 * 12.01g/mol + 3 * 16.00g/mol = 83.91g/mol. From this, we can convert 4.2g of NaHCO3 to moles by dividing by 83.91g/mol, to get 0.050 moles of sodium bicarbonate.</span>
Answer:
Precipitation reactions are ones in which at least one of the reactants is in the aqueous phase (i.e., dissolved in water), and a solid forms on the product side which was not present on the reactant side. If all the reactants are solid, then a solid product forming should not be called a precipitate. To be called a precipitate, an insoluble product must form from within solution, either from a solid and solute interacting, or from an interaction strictly between solutes.

Answer:
Gas ⟶ liquid (condensation)
Explanation:
If the molecules are far apart, they are in the gas phase.
As the temperature drops, the molecules lose kinetic energy.
They can no longer escape the attractive forces between them and their neighbours, so they stick together and form a liquid.
The most likely change of state is gas ⟶ liquid (condensation).
Answer:
The value of Keq is 4e-9. See the solution below
Explanation:
We need to balanced rhe equation and use the formula of the Keq
