Answer:
14.0 g
Explanation:
Step 1: Write the balanced equation
2 Cu₂O + Cu₂S ⇒ 6 Cu + SO₂
Step 2: Calculate the moles corresponding to 10.5 g of copper (I) oxide
The molar mass of Cu₂O is 143.09 g/mol.
Step 3: Calculate the moles of copper produced from 0.0734 moles of copper (I) oxide
The molar ratio of Cu₂O to Cu is 2:6. The moles of Cu produced are 6/2 × 0.0734 mol = 0.220 mol
Step 4: Calculate the mass corresponding to 0.220 mol of copper
The molar mass of Cu is 63.55 g/mol.

<u>Individual lipid molecules are free to diffuse laterally in the surface of the bilayer</u> is a general feature of the lipid bilayer in all biological membranes
Explanation:
The inside of the bilipid layer of the cell membrane of cells is made of fatty acid chains and cholesterol which are nonpolar molecules. they are sandwiched between the polar (glycerol) ends of the chains because they are hydrophobic and cannot interact with the ‘watery’ extracellular fluids. Non-polar molecules like lipids can easily diffuse laterally, within this lipid layers of the membrane because non-polar molecules interact well with other nonpolar molecules.

Answer:
Yes
Explanation:
Scientific laws must always be accompanied by theories. Without theories, laws cannot be formed. In other words, scientific laws are made from scientific theories.
<em>When a hypothesis has been tested by several independent researchers and found to be true, this leads to the development of a theory. A theory becomes a law when it is able to hold true against a wide range of similar phenomena.</em>
<span>2Fe:3O is the answer </span>
You can determine the mass defect when you calculate for the absolute difference of the experimentally determined molar mass and the theoretical molar mass.
64Ni means there are 28 protons, 28 electrons and (64 - 28) = 36 neutrons. The mass of each proton is 1.0072766 amu; the mass of each electron is <span>0.00054 </span>amu; the mass of each neutron is <span>1.008664 amu.
Theoretical molar mass = 28(</span>1.0072766 amu) + 28(0.00054 amu) + 36(1.008664) = 64.5308 amu
Thus,
Mass defect = |63.9280 amu - 64.5308 amu| = <em>0.6028 amu</em>
