stepladder [879]

Answer:

The answer is "670.176 km".

Explanation:

Volume of the occupies of one  M & M= 0.5 \ cm^3\\\\

M&M 1 mole= 6.02 \times 10^{23}\\\\

Calculating volume of M& M mole=  0.5 \ cm^3 \times 6.02 \times 10^{23}=3.01 \times 10^{23}\ cm^3\\\\

Calculating the cube moleL^3= 3.01 \times 10^{23}\ cm^3\\\\

L=6.70176 \times 10^{7}\ cm\\\\

   =6.70176 \times 10^{7}\ cm \times \frac{1\ m}{100\ cm}\\\\=670176\ m\\\\=670.176 \ km

Therefore 18 tractor trailers wouldn't be sufficient.

Suppose a new liquid were discovered that is identical to water in every way except that it has a lower latent heat of fusion. W
faltersainse [42]

Answer:

It would take less time, because having a lower temperature of latent heat means that at a lower temperature it merges, therefore the closer it will be to the temperature of solification which is 0 degrees Celsius or Celsius ... It is then that it would solidify in less time than water

Explanation:

By acting and having all the same properties as water except for latent heat, it considers that the solidification temperature is 0 degrees Celsius like water.

Rank the following bonds in order of decreasing bond length, based on periodic trends, starting with the longest bond at the top
sattari [20]

Answer:

H-BI,H-Se,H-S,H-I,H-Br

Explanation:

One thing that must be kept in mind is that atomic size increases down the group and decreases across the period. The bond lengths of species are influenced by the relative sizes of atoms or ions present in the bond.

The bonds in the answer have been arranged on basis of their decreasing atomic size because the greater the atomic size of the atoms, the greater the bond length and vice versa.
