Answer:
cyclohexane
Explanation:
Solubility is determined by the principle , "like dissolves like" .
i.e. , if a compound is polar then it will dissolve in a polar compound only , and
if a compound is non - polar then it will dissolve in a non - polar compound only .
Hence , from the question ,
a good solvent for cyclopentane would be cyclohexane ,
since , both the compounds are non polar in nature , hence get solubilized ,
the other options mentioned are polar .
Answer:
Sound needs a medium through which to travel.
Explanation:
In space there is no air or medium. Sound waves need medium to travel. It cannot travel through vacuum. Sounds waves are mechanical waves unlike electromagnetic waves. Electromagnetic waves can travel through vacuum. But mechanical waves such as sound waves needs a medium to propagate the energy. So it is very unlikely that people inside the space station can hear the explosion that occurs in space outside the space station.
Answer:
Carbon dioxide is a gas at room temperature
Magnesium hydroxide react with hydrochloride to give magnesium chloride and water
THe word equation
magnesium hydroxide +hydrochroric acid---> Magnesium chloride+water
chemical equation
Mg(OH)2(S) + 2HCl (L)--> Mgcl2(S) + 2H2O(l)
when balancing the equation we count the number of molecules in the reactant side which should balance with molecules in the product side.
<u>Answer:</u> The concentration of zinc oxalate is 
<u>Explanation:</u>
To calculate the molarity of solution, we use the equation:
We are given:
Moles of zinc oxalate = 
(Conversion factor: 
)
Volume of solution = 450 mL
Putting values in above equation, we get:
In case of multiplication and division, the number of significant digits is taken from the value which has least precise significant digits. Here, the least precise number of significant digits are 2.
Hence, the concentration of zinc oxalate is
