Determine how many atoms of silver would be produced if 100 grams of copper reacts with an excess of silver nitrate? given the equation: cu + 2 agno3 -> cu(no3)2 + 2 ag avogadro's number: 6.02 x 1023

-

2 x 10 ²⁴ atoms of Ag rounded off to 1 significant figures.

Explanation: -

Mass of Cu = 100 g

Molar mass of Cu = 63.55 g / mol

Number of moles of Cu = 100 g / (63.55 g/mol)

= 1.574 mol of Cu

The balanced chemical equation for the reaction is

Cu + 2AgNO₃ → Cu(NO₃)₂ + 2 Ag

From the balanced chemical equation we see

1 mol of Cu gives 2 moles of Ag

1.574 mol of Cu gives

= 3.148 mol of Ag

1 mole of Ag has 6.02 x 10 ²³ atoms of Ag according to Avogadro's Law.

3.148 mol of Ag has

= 18.95 x 10²³ atoms of Ag

= 2 x 10 ²⁴ atoms of Ag rounded off to 1 significant figures.

because u need two or more forms of the same element that contain equal numbers of protons but different numbers of neutrons in their nuclei to form isotopes.

so since they all have the same shape? i mean maybe because m& m and reeses are both chocolates

the earth would become to overheated and everything alive on it will eventually die from overheating. plants will eventually die as well, water will evaporate, and it will be nothing but a hot planet without anything living on it.
