Answer:

32.84002

Explanation:

average atomic mass= F1A1 + F2A2 + F3A3 so that means 60/100*34.456+23/100*37.457+9/100*39.459

How many significant figures does 546.000 have

choli [55]

This has only only three sig figs because it is 546.000 the zeros are just place holders so thus meaning they are not significant. It is just another way to write 546 because in that number there is also 3 sig figs. They are just trying to throw you off. Just watch out because if the example is 540 then it is just two significant digits, and it were to be 540. then it be three cause that "." makes the zero significant. <span />

A rectangular tank is filled with water to a depth = h, the tank width and length are w and 1 respectively. Calculate the ratio

AnnZ [28]

Answer:

$\frac{\textup{2}}{h}$

Explanation:

Given:

Depth = h

Width = w

Length = 1

Now,

Let ρ be the density of water

Thus,

Pressure force at the bottom will be

= Pressure × Area

= ρgh × (w × 1)

also,

Pressure force at the sides will be = $\frac{\textup{1}}{\textup{2}}\times$ ρgh × (h × w)

Therefore,

The ratio of the pressure force at the bottom to the pressure force on the side of the tank will be

= $\frac{\rho gh\times w\times1}{\frac{1}{2}\times\rho gh\times(h\timesw)}$

= $\frac{\textup{2}}{h}$

Draw the structure of two alkenes that would yield 1-methylcyclohexanol when treated with Hg(OAc)2 in water, then NaBH4:Draw the

disa [49]

Answer:

Two possible compounds are shown below- one with an exocyclic double bond and another one with an endocyclic double bond

Explanation:

Reaction of alkene with $Hg(OAc)_{2}$ gives a complex of mercurous ion.

Then water molecule attacks this complex through $S_{N}2$ type reaction at more substituted position.

$NaBH_{4}$ cleaves the resultant C-Hg bond and forms a C-H bond.

Two possible structures of an alkene is possible to yield 1-methylcyclohexanol which are shown below.
