Answer:
47.8 g
Explanation:
Remember the equation for percent yield:
% yield = actual / theoretical
We're given two of the values in the question, so plug n' play:
0.945 = 45.2 / theoretical
theoretical = 47.8 g
Keep in mind you can use mass here without converting to moles because we're working with products only. If you were given a mass of reactants, you would need to convert to moles and using a balanced chemical equation find the corresponding moles of product produced.
Answer:
Explanation:
Alkaline are great for long-term use in a device, such as in a digital camera or game console remote. Carbon zinc batteries are ideal in a situation where one needs to power multiple devices for one occasion, such as when buying many toys during the Christmas season to be used for a few days.
The solution process is exothermic because when solution become colder heat energy is released which make the process exothermic. The exothermic process is the process in which heat is released.The solution forms inorder to separate NH4+ ions and Cl- ions
Answer:
A
Explanation:
Since water is polar, we need for there to be a polar solute. This eliminates options B and D.
Now to choose between A and C, we can look at the compounds mentioned.
For A, NH3 is mentioned, which is a polar substance.
However, for C, H2 is mentioned, which is a nonpolar molecule, contrary to what is stated by the option.
Therefore, A is the answer.
Answer
Explanation:
85.9 (g C) = 85.9 (g C) / 12.00 (g/mol C) = 7.158 (mol C)
7.158 (mol C)*[6.022*1023 (atoms/mol C)] = 4.31*1024 C-atoms
