Among ¹⁴⁰₅₅Cs and ¹³³₅₅Cs,  <u>¹³³₅₅Cs</u> is more stable.

<h3>Briefly explained</h3>

Let's review the criteria that are used to determine a stable isotope. A stable isotope will have more neutrons than protons with a neutron to proton ratio somewhere between one and 1.52 On the high atomic number, we're up to 152 at low atomic numbers were closer to one. More stable isotopes have an even number of protons. And neutrons.

And stable isotopes have their proton or neutron number equal to one of these magic numbers. So if we have season one, It has 85 Protons are start 85 neutrons And 55 protons. So we have a neutron to proton ratio of 155 for CCM 1 33. We have 78 neutrons and 55 protons for a neutron to proton ratio of 1.42. 155 is a little high for z equal to 55.

Both of these are also odd. So ¹⁴⁰₅₅Cs is the least stable. ¹³³₅₅Cs is the most stable.

What characteristic frequencies in the infrared spectrum of your sodium borohydride reduction product will you look for to deter
kkurt [141]

Answer:

A)The characteristic frequency to look out for is  1720-1740 cm-1 (for C=O) for which will disappear in the end product but initially present in the reactant.

B)Characteristic frequency  present in the infrared spectrum will be at a peak of  3300-3400 cm-1 which will be due to O-H stretch.

C)If the product is wet with water there will be no change in the infrared spectrum

Explanation:

The characteristic frequency to look out for is  1720-1740 cm-1 (for C=O) for which will disappear in the end product but initially present in the reactant.

Characteristic frequency  present in the infrared spectrum will be at a peak of 3300-3400 cm-1 which will be due to O-H stretch.

If the product is wet with water there will be no change in the infrared spectrum

You find a ring with a mass of 107g . You fill a graduated cylinder up with 10ml of water and put the ring into the cylinder . T
Korvikt [17]

Answer:

5 mL

Explanation:

Given data:

mass of ring = 107 g

volume of water = 10 mL

increase in volume = 15 mL

How much water displace = ?

Solution:

V (ring) = V (water + ring) - V (water)

V (ring) = 15 mL -  10 mL

V (ring) = 5 mL

when the ring is put into cylinder, volume is increased by 15 mL. The volume of water was 10 mL so water is displaced by 5 mL and the volume 5mL is the voulme of ring.
