Answer:
2.02 × 10²³ atoms
Explanation:
Step 1: Calculate the moles corresponding to 37.8 g of cadmium
To convert mass to moles, we need a conversion factor: the molar mass. The molar mass of cadmium is 112.41 g/mol.
37.8 g × 1 mol/112.41 g = 0.336 mol
Step 2: Calculate the number of atoms in 0.336 moles of cadmium
To convert moles to atoms, we need a conversion factor: Avogadro's number. In 1 mole of atoms of cadmium, there are 6.02 × 10²³ atoms of cadmium.
0.336 mol × 6.02 × 10²³ atoms/1 mol = 2.02 × 10²³ atoms
Answer:
It is physical since nothing from the popsicle is changing
Explanation:
During a neutralization reaction phosphoric acid reacts with potassium hydroxide to produce potassium phosphate and water, the reaction occurs with a 64.9% yield.
A neutralization reaction is a chemical process in which an acid and a base combine to produce salt and water as the end products. In a neutralization process, a mixture of H+ ions and OH- ions results in the formation of water.
Potassium phosphate and water are created when potassium hydroxide and phosphoric acid combine. The reaction's balanced equation is as follows: K3PO4(aq) + 3H2O = 3KOH(aq) + H3PO4(aq) (l) If six moles of potassium hydroxide react, phosphoric acid is used in the reaction.
