<span>In bonding with another element, magnesium has an oxidation number of +2. It gives away 2 electrons when it bonds. It will most easily bond with an element that accepts 2 electrons. [ With an oxidation number of -2 that is oxygen, which contains 6 electrons in its valence shell. </span>

A chemistry student needs 10.00 g of isopropenylbenzene for an experiment. He has available 120. g of a 42.7% w/w solution of is
Vanyuwa [196]

<u>Answer:</u> The mass of solution that the chemistry student should use is 23.4 grams

<u>Explanation:</u>

We are given:

Available mass of isopropenylbenzene = 120. g

Amount of isopropenylbenzene needed by chemistry student = 10.00 g

42.7 % (w/w) solution of isopropenylbenzene.

This means that 42.7 grams of isopropenylbenzene is present in 100 grams of solution.

To calculate the mass of solution for given needed of isopropenylbenzene, we apply unitary method:

For 42.7 grams of isopropenylbenzene, the amount of solution needed is 100 grams

So, for 10.00 grams of isopropenylbenzene, the amount of solution needed will be = \frac{100}{42.7}\times 10=23.4g

Hence, the mass of solution that the chemistry student should use is 23.4 grams

Which band is the smallest within the electromagnetic spectrum? A) X rays B) microwaves C) radio waves Eliminate D) visible ligh
aev [14]
Radio   wave  eliminate  band (answer  c) is  smallest   within  electromagnetic  spectrum.
  
   The  electromagnetic  spectrum  is  the  range  of  frequencies  (the  spectrum)  of    electromagnetic  radiation   and  their  respective  wavelength and  photon  energies.  The   electromagnetic  spectrum  range from   radio  waves  to  gamma  rays.Radio waves  has  the  shortest  wavelength  while   gamma rays  has  highest.

 the sand is more likely to be hot because it is on land and the sun can be very hot so i think it would heat the sand.  but water is less likely to be heated because its water. and the sun's heat on it would still affect it yes, but not as much as sand
