Answer:
0.570 L
Explanation:
Given:
Concentration of the HCl solution = 0.750 M
Mass of NaCl in the reaction = 25.0
Number of moles of NaCl in the reaction = Mass of NaCl / Molar mass of NaCl
also,
Molar mass of NaCl = 22.98 + 35.45 = 58.43 grams
thus,
Number of moles of NaCl in the reaction = 25 / 58.43 = 0.4278 moles
now,
1 mol of NaCl reacts to form 1 mol of HCl
thus,
0.4278 moles of NaCl reacts to form 0.4278 mol of HCl
also,
Concentration = Moles / volume of solution
0.750 = 0.4278 / volume of solution
or
volume of solution = 0.570 L
3-hexene shows geometrical isomers .
The geometrical isomers of 3-hexene are cis-3-hexene and trans-3-hexene.
Trans isomer has a higher melting point than cis isomer . the cis isomer has high boiling point . dipole moment is low in case of trans and high in case of cis .
<h3>What is isomerism ?</h3>
it is a type of phenomena in which two or more compounds have same molecular or chemical formula but have different structure or spatial arrangement in 3D space .
<h3>Isomers :</h3>
same molecular formula but different physical or chemical properties .
<h3>What is geometrical isomers ?</h3>
it is a type of stereoisomers which have same molecular formula and same structure but different arrangement of atoms in space .

Answer:
Density is a measure of how heavy something is compared to its size. If an object is more dense than water it will sink when placed in water, and if it is less dense than water it will float.
