Two reason someone would want to become a scientist to make exciting discoveries and discovered new life on our planet. Also you could solve huge problems that somebody else couldn’t solved. This is why somebody would want to be a scientist.
<u>Answer:</u> The molarity of saline solution is 0.909 M
<u>Explanation:</u>
We are given:
5.21 w/w % NaCl
This means that 5.21 grams of NaCl is present in 100 grams of solution
To calculate mass of a substance, we use the equation:

Density of solution = 1.02 g/mL
Mass of solution = 100 g
Putting values in above equation, we get:

To calculate the moalrity of solution, we use the equation:

Given mass of NaCl = 5.21 g
Molar mass of NaCl = 58.44 g/mol
Volume of solution = 98.04 mL
Putting values in above equation, we get:

Hence, the molarity of saline solution is 0.909 M
Answer:
1)The proximity of the positively charged phosphorous and negatively charged carbon stabilizes the charges.
2) Inductive effects and resonance stabilize the negative charge
Explanation:
both atoms have full octets of electrons( I.e Carbon and say phosphorus). The result can be viewed as a structure in which two adjacent atoms are connected by both a covalent and an ionic bond; normally written X+–Y−. Ylides are thus 1,2-dipolar compounds, and a subclass of zwitterions
I'm gonna assume you mean copper
Copper<span> is a chemical element with symbol Cu (from Latin: cuprum) and atomic number 29. It is a soft, malleable, and ductile metal with very high thermal and electrical conductivity. A freshly exposed surface of pure </span>copper<span> has a reddish-orange color.</span>
Depends on how you separate it
