Reactant atoms and molecules are the starting materials in a chemical reaction, while product atoms and molecules are the substances formed as a result of the reaction. During the reaction, reactant atoms and molecules are rearranged and transformed into new products with different chemical properties. The number and types of atoms remain the same, but their arrangement and interactions change.

To find the weight of 4.6 x 10^25 atoms of copper, you can start by calculating the molar mass of copper, which is approximately 63.55 g/mol. Next, convert the number of atoms to moles by dividing by Avogadro's number (6.022 x 10^23). Finally, multiply the number of moles by the molar mass to find the weight in grams.
First you need to organize what you need to determine the number of atoms in 1 mg of As. You need to know the following:1 mol As = 74.92160g As (from the periodic table)1 mol As = 6.022 x 1023 atoms As (Avogadro's number)1000mg = 1g As (conversion from mg to g)Now we start the calculations:1) Convert mg to g.1mg As x (1g/1000mg) = 0.001g As2) Convert g As to moles As0.001g x (1mol As/74.92160g As) = 1.3 x 10-5mol As3) Convert mole As to atoms of As1.3 x 10-5mol As x (6.022 x 1023 atoms As/1mol As As) =7.8 x 1018 atoms AsSo, the answer to your question, is that 1mg of As has 7.8 x 1018 atoms As
Because of the concept of conservation of mass. the mass remains unchanged because the chemical reaction is caused by the interaction of electrons with eachother as opposed to atoms actually destroying or combining with eachother
To determine the number of potassium atoms in the reactants of a chemical reaction, you would need to look at the chemical equation for the reaction and count the number of potassium atoms on the reactant side. The coefficient in front of the potassium-containing compound in the reactants indicates how many potassium atoms are present in that compound.
In a chemical reaction, the number of atoms of reactants must be equal to the number of atoms of products to satisfy the law of conservation of mass. This means that atoms are rearranged but not created or destroyed during a chemical reaction.
When faced with a problem, you start with a general theory of all possible factors that might affect an outcome and deduce from it specific hypothesis (or predictions) about what might happen.

To find the mass of 1.63 x 10^21 silicon atoms, you can start by calculating the molar mass of silicon (28.0855 g/mol). Then, divide the total number of atoms by Avogadro's number to find the number of moles (moles = atoms / Avogadro's number). Finally, multiply the number of moles by the molar mass to find the mass.
Start with 1, 2 as the first two numbers. Subtract those numbers from the original number. The remaining number is one possible outcome. Dont be a dingus next time.
To balance the equation Fe + H2O → Fe3O4 + H2, you need to ensure the number of atoms of each element are equal on both sides. Start by balancing the iron atoms, then balance the oxygen atoms, and finally balance the hydrogen atoms. The balanced equation is 3Fe + 4H2O → Fe3O4 + 4H2.
To calculate the empirical ratio in chemistry, you need to divide the number of atoms of each element in a compound by the smallest number of atoms present. Then, if needed, you can multiply the ratio by a whole number to obtain a whole number ratio. For example, in water (H2O), the empirical ratio is 2:1 (2 hydrogen atoms for every 1 oxygen atom).
To find the number of atoms in 1.25 moles of LiBr, you first need to calculate the molar mass of LiBr. The molar mass of LiBr is approximately 86.845 g/mol. Next, you can use Avogadro's number to convert moles to atoms. So, 1.25 moles x 6.022 x 10^23 atoms/mol equals approximately 7.53 x 10^23 atoms of LiBr.

To find the number of fluorine atoms in 5.59 g of C2F4, start by calculating the molar mass of C2F4: 12.01 g/mol (C) + 2(19.00 g/mol) (F) = 70.01 g/mol. Then divide the given mass by the molar mass to get the number of moles: 5.59 g / 70.01 g/mol ≈ 0.08 moles. Since there are 4 fluorine atoms in 1 molecule of C2F4, multiply the number of moles by Avogadro's number (6.022 x 10^23) and then by 4 to get the number of fluorine atoms: 0.08 mol x 6.022 x 10^23 atoms/mol x 4 = approximately 1.93 x 10^23 fluorine atoms.
