Cation and anion cause covalent bonds
:- At cation positive charge are held and at anion negative. .. there is a strong bond between them. ....
Nah fam, supersaturate is very hard to get. It actually creates crystals and can only be made through using techniques to improve the solubility of the solution.
This would be false. It is a saturated solution
Answer:
The mass of the precipitate that AgCl is 3.5803 g.
Explanation:
a) To calculate the molarity of solution, we use the equation:
![\text{Molarity of the solution}=\frac{\text{Mass of solute}\times 1000}{\text{Molar mass of solute}\times \text{Volume of solution (in mL)}}](https://tex.z-dn.net/?f=%5Ctext%7BMolarity%20of%20the%20solution%7D%3D%5Cfrac%7B%5Ctext%7BMass%20of%20solute%7D%5Ctimes%201000%7D%7B%5Ctext%7BMolar%20mass%20of%20solute%7D%5Ctimes%20%5Ctext%7BVolume%20of%20solution%20%28in%20mL%29%7D%7D)
We are given:
Mass of solute (NaCl) = 1.46 g
Molar mass of sulfuric acid = 58.5 g/mol
Volume of solution = ![250 cm^3 =250 mL](https://tex.z-dn.net/?f=250%20cm%5E3%20%3D250%20mL)
![1 cm^3= 1 ml](https://tex.z-dn.net/?f=1%20cm%5E3%3D%201%20ml)
Putting values in above equation, we get:
![\text{Molarity of solution}=\frac{1.46g\times 1000}{58.5g/mol\times 250}\\\\\text{Molarity of solution}=0.09982 M](https://tex.z-dn.net/?f=%5Ctext%7BMolarity%20of%20solution%7D%3D%5Cfrac%7B1.46g%5Ctimes%201000%7D%7B58.5g%2Fmol%5Ctimes%20250%7D%5C%5C%5C%5C%5Ctext%7BMolarity%20of%20solution%7D%3D0.09982%20M)
0.09982 M is the concentration of the sodium chloride solution.
b) ![NaCl (aq)+AgNO_3 (aq)\rightarrow AgCI(s)+NaNO_3(aq)](https://tex.z-dn.net/?f=NaCl%20%28aq%29%2BAgNO_3%20%28aq%29%5Crightarrow%20AgCI%28s%29%2BNaNO_3%28aq%29)
Moles of NaCl = ![\frac{1.46 g}{58.5 g/mol}=0.02495 mol](https://tex.z-dn.net/?f=%5Cfrac%7B1.46%20g%7D%7B58.5%20g%2Fmol%7D%3D0.02495%20mol)
according to reaction 1 mol of NaCl gives 1 mol of AgCl.
Then 0.02495 moles of NaCl will give:
of AgCl
Mass of 0.02495 moles of AgCl:
![0.02495 mol\times 143.5 g/mol=3.5803 g](https://tex.z-dn.net/?f=0.02495%20mol%5Ctimes%20143.5%20g%2Fmol%3D3.5803%20g)
The mass of the precipitate that AgCl is 3.5803 g.
Answer:
The answer is
D. Main sequence
Explanation:
Main sequence stars can be between one thousand times dimmer and one million times brighter than the Sun.
What is main sequence stars?
A main sequence star is any star that is fusing hydrogen in its core and has a stable balance of outward pressure from core nuclear fusion and gravitational forces pushing inward.
Actually, there are four kinds of reptile motion:
Concertina - vermiform. Circular muscles around the snake squeeze the front of the snake's body out long, then the latter half is pulled forward.
Rectilinear crawling - Belly scutes are moved forward individually in a wave-like motion.
Side-winding - Snake's version of "walking". Use by several species to move over fluidic substrates, such as sand.
Lateral undulation - Most common form of movement. Snake presses on alternating pressure points to force body forward (or backward)
