The percentage of glucose given is m/v. This means that the given percentage of volume consists of mass.
In this solution, percentage of glucose is 5.5% m/v.
This means that 5.5% of the volume is the mass of glucose.
Given volume is 285 mL.
Therefore mass of glucose is 5.50% of 285 mL = (5.5*285)/100
mass of glucose = 15.67 g
1.7 liters of water will be produced.
Explanation:
The balanced chemical reaction is:
2H2+ 02⇒ 2H20
Considering the reaction to be at STP (P = 1atm, V= 22.4 L, T = 273.15 K)
the formula used is:
PV = nRT
Where P, R and T remains same only volume and number of moles are different so,
= 
observing the balanced reaction:
mole ratio is 2:2 i.e 1:1
so volume ratio will also be same
so 1.7 litres of water will be produced.
From the reaction it is seen that
1 mole hydrogen react with oxygen to give 1 mole of water at STP.
so, it is found that 1.7 liters of hydrogen gives 1.7 liters of water
Answer:
6.63 M
Explanation:
NaCl(s) ---> Na^+(aq) + Cl^-(aq)
Given that [Na^+] = [Cl^-] = s
Where s= concentration of the both ions
Ksp = s^2
s= √Ksp
s= √43.9
s= 6.63 M
Answer:
HCl, also known as hydrochloric acid, has a covalent bond. The hydrogen (H) atom shares an electron with the chlorine (Cl) to form the bond.
Explanation:
Consequently, the bonding electrons in hydrogen chloride are shared unequally in a polar covalent bond. The molecule is represented by the conventional Lewis structure, even though the shared electron pair is associated to a larger extent with chlorine than with hydrogen.
