Answer:
Models aren't always 100% accurate. The world is ever-changing and so is everything in it. There is no sure way to know that your model is accurate all the time. Also, models aren't always easy to read. Some people struggle to read models, therefore models cannot be used by everyone.
Explanation:
These are just two of the limitations. Let me know if you need more. Happy to help : )
Answer:
7.53*10^23 atoms
Explanation:
Using stoichiometry convert moles of silver to moles of copper. Based on the equation, for every 2 moles of silver, 1 mole of copper is produced.
Then, convert moles to atoms with Avogadro's number.
Your answer should be 7.53*10^23 atoms.
Answer:
Sugar is made through photosynthesis and without light the plant will not produce sugar. so the answer is plant x dark orange and plant y is dark purple.
hope it helps! pleas give me brainliest.
Dipole moment can be defined as the product of magnitude of charge and the distance of separation between the charges. A dipole exists when two or more atoms with different electronegativities are bonded together to form a molecule. The resulting unequal sharing of electrons leads to a molecule with a net positive and a net negative end. Hence the molecule is said polar.
Bonds between carbon and oxygen (C=O) are more polar but carbon dioxide (CO2) does not exhibits a dipole moment because CO2 is a linear molecule and the charge is equally distributed amongst the entire molecule. When molecules have an even charge distribution then there is no dipole moment and the molecule is said to be non-polar. CO2 is a linear molecule, so the dipoles are symmetrical and are equal in magnitude but point in opposite directions so they cancel out each other effect and we get net dipole moment zero.
On the other hand sulfur dioxide (SO2) exhibits a dipole moment because unlike CO2 molecule SO2 is not a linear molecule because of the presence of lone pair on Sulfur (S) atom , the geometry of SO2 is bent. This bent orientation of the oxygen's with respect to the sulfur results in the uneven distribution of positive and negative charges between the sulfur atom and the two oxygen atoms in the diagonal-shaped sulfur dioxide molecule. So the dipoles are not equal in magnitude and they do not cancel out and SO2 molecule exhibit a net dipole moment.
NOTE: If the molecule is linear, the dipoles are equal and exactly opposite in direction, so like a perfectly equal tug-of-war, they cancel each other out, and there is no net dipole in the molecule.
CO2 (linear molecule) = The dipoles are equal and exactly opposite in direction. They cancel each other out, and there is no net dipole in the molecule.
SO2 ( bent shape not linear) = Their is an uneven distribution of positive and negative charges between the sulfur atom and the two oxygen atoms. Dipoles are not equal in magnitude and they do not cancel out and SO2 molecule exhibit a net dipole moment.
Answer:
<em><u>Percent volume-volume (%(v/v)) = 100 x (volume of solute / volume of solution)</u></em>
<em><u>Percent volume-volume (%(v/v)) = 100 x (volume of solute / volume of solution)ex. 20 ml of methanol dissolved in enough water to make 200 ml of solution would result in a 10 % methanol solution</u></em>
<em><u>Percent volume-volume (%(v/v)) = 100 x (volume of solute / volume of solution)ex. 20 ml of methanol dissolved in enough water to make 200 ml of solution would result in a 10 % methanol solution-the units may be any units of volume you chose - as long as they are consistent</u></em>
