Alona [7]3 years ago
7 0

I'm not sure but it should be 7.31 times 2 times 3.14 or pi

7.31 x 2 x 3.14 = 45.9068

If you need to round to the nearest tenth it will be 45.9

If you need to round to the nearest hundredth it will be 45.91

What is reacitivty series, and how you can access reactivity of metals...
lubasha [3.4K]

In Chemistry, a reactivity series of metals , also known as the activity series refers to the arrangement of metals in the descending order based upon their reactivity .

<u>Salient Features</u> :-

  • The metal at the top of the reactivity series are powerful reducing agents since they are easily oxidized.
  • The reducing ability of metals grows weaker while traversing down the series.
  • The electro-positivity of metals also reduces while moving down the reactivity series.
  • Metals that are placed higher on the reactivity series have the ability to displace metals that are placed lower in the series.

<u>The metal reactivity series is given below</u> :-

To access the reactivity of metal , from the given reactivity series identify any of the metal and locate the reactivity based upon the choice of reactivity. The metal at the top (Potassium) is most reactive and the metal at the bottom (Platinum) is the least reactive.

Answer:

The question has some part missing which I have added in the attachment.

Explanation:

The reactions given occur under certain reagents, which we are told to pick for each of the reaction synthesis. Conventionally, halogens have the ability to undergo addition reactions with hydrocarbons by breaking down the double or triple bond in them to a single bond, this usually occur by electron donation and electron acceptor.

The attachment shows the reactions and the necessary reagents required for each

What is the mass, in grams, of 7.20×1020 molecules of caffeine, c8h10n4o2?
pickupchik [31]
To determine the mass, you need to know the molecular weight of the c8h10n4o2 . The molecular weight of <span>c8h10n4o2 would be: 8*12 + 10*1 + 4*14 + 2*16= 194g/mol.
To convert the number of molecules into moles, you need to divide it with 6.02 * 10^23. The calculation of the mass of </span>c8h10n4o2 would be: 
(7.20×10^20 molecules)  /(6.02 * 10^23 molecule/mol)  * 194g/mol= 232 * 10^-3 grams= 0.232 grams

Gamma rays contain much more energy (most penetrating) than radio waves because they have a greater frequencies.
Radio waves are the electromagnetic waves with the longest wavelengths (1dm to 100 km), lowest frequencies (3kHz to 3GHz) and lowest energy (124 peV to <span>12,4 μeV).
</span>Gamma rays are the electromagnetic waves with the shortest wavelengths (1 pm), highest frequencies (300 EHz) and highest energy (1,24 Me<span>V</span>).
