Answer:
62.5%
Explanation:
Number of moles of camphor reacted= 1.6g/152.23 g/mol = 0.011 moles
Since the reaction is 1:1, then 0.011 moles of isoborenol is also produced.
Theoretical yield of isoborenol produced = 154.25 g/mol * 0.011 moles = 1.698 g
% yield = actual yield/theoretical yield * 100
% yield = 1.062 g/1.698 g * 100
% yield = 62.5%
Answer:
67.91 g of CuCl2; 32.09 g of Cu.
Explanation:
The two masses add to 100.0 g, the initial amount of starting material, demonstrating the law of conservation of matter.
Since this element has 50 electrons you know that it has 50 protons. The number of proton= the atomic number. Atomic number 50 is tin. The atomic symbol for tin is Sn and the weight is 120. So this is the tin 120 isotope
Answer:
To find out what water is made of, it helps to look at its chemical formula, which is H2O. This basically tells us that the water molecule is composed of two elements: hydrogen and oxygen or, more precisely, two hydrogen atoms (H2) and one oxygen atom (O). Hydrogen and oxygen are gases at room temperature.
