Water has the ability to dissolve polar covalent molecules like sucrose by

Alla [95]

Explanation:

Sucrose is a disaccharide which is composed of fructose and glucose. Sucrose molecule has oxygen atoms bonded to hydrogen atoms (O-H bonds - Polar groups) on all ends of its double 6-Carbon ring. The areas near the oxygen atoms are slightly negative, and the areas near the hydrogen atoms are slightly positive that is, the O-H bonds are polar. They bond with the neighbouring Oxygen and Hydrogen atoms because of their

dipole - dipole attractions and hence hydrogen bonds are formed.

However, the covalent bonds within the molecule aren't broken. But rather, the hydrogen bonds holding the sucrose molecules in the crystalline lattice.

exis [7]

Answer:

$27.5\ m$

Explanation:

As we know that volume of cylinder is

$v=\pi r^{2} *h$

Where v=volume , h= height or thickness and r= radius

Here,

$v= 10 m ,\ diameter= 10, \ r=\frac{diameter}{2} \ r=\frac{10}{2}\\ r=5$

Putting these values in the previous equation , we get

$10\ = \frac{22}{7} *5 *5*h\\ 14\ =\ 110*h\\h=\frac{110}{14} \\h=\frac{55}{2} \\\\h=27.5\ m$

Therefore thickness is 27.5 m

You want to see how your new belt buckle matches your new hat. Your eyes are 114 mm below the top of the hat and 800 mm above th

damaskus [11]

Answer:

$x=0.057m$

$h=0.457m$

Explanation:

From the question we are told that

Distance of eyes from the top of hat $d_1=114mm$

Distance of eyes from buckle $d_2=800mm$

Generally position of mirror relative eyes x is mathematically given as

$x=\frac{114}{2}$

$x=57mm$

$x=0.057m$

Generally the height of the mirror h is mathematically given as

$h=\frac{(Buckle\ below\ the\ hat)+(Buckle\ below\ the\ hat)}{2}$

$h=\frac{(114)+(800)}{2}$

$h=457mm$

$h=0.457m$
