This heat is 32,48 joules.
The Avogadro number: 6,02214129(27)×1023.
The molar ratio of Na to O2 in the reaction 2Na + O2 -> 2Na2O is 2:1. This means that for 23g of Na, we need half as many grams of O2, which is calculated as 23g * (1/2) = 11.5g of O2.
To find the number of moles in 16g of NaCl, we first need to calculate the molar mass of NaCl, which is approximately 58.44 g/mol. Then, we can use the formula: moles = mass / molar mass moles = 16g / 58.44 g/mol moles ≈ 0.27 mol
To calculate the moles of carbon dioxide, we first need to determine the number of moles of oxygen in 16g. Using oxygen's molar mass of 16 g/mol, we find that there is 1 mole of oxygen in 16g. Since one mole of oxygen reacts with one mole of carbon dioxide in the balanced equation, there will also be 1 mole of carbon dioxide formed.
In 16g of O, there are approximately 3.02 x 10^23 atoms, as the atomic mass of oxygen is 16 g/mol. In 8g of S, there are approximately 6.02 x 10^23 atoms, as the atomic mass of sulfur is 32 g/mol.
That is 3.2 teaspoons.

Well 1g=1000 mg so 16g=16000 mg

First, determine molar mass of CH4: C:12g/mol + 4x H:1g/mol= 16g/mol Then divide by the number of grams. 64g/(16g/mol)= 4 moles of CH4
To find the number of moles in 16g of NaCl, we first need to calculate the molar mass of NaCl, which is approximately 58.44 g/mol. Then, we can use the formula: moles = mass / molar mass moles = 16g / 58.44 g/mol moles ≈ 0.27 mol
