Vikki [24]3 years ago
5 0

Answer: Another name for beta-minus particle is electron.

Explanation: Beta-minus particle (_{-1}^0\beta ) is released during the beta-minus decay nuclear reaction.

In this nuclear reaction, a neutron gets converted into proton and electron. The electron released is the beta-minus particle.

The charge on these particles is -1 and mass of these particles is negligible.

vova2212 [387]

Answer:

Endothermic  

Explanation:

The temperature of the water decreased.

The water lost heat.

The heat must have gone into getting the KNO₃ into solution.

So, the dissolving of KNO₃ in water is endothermic.

Strigol is an important plant hormone that is released by crops such as rice and sugarcane. Unfortunately for these plants, stri
Len [333]

The hydrogen deficiency index( HDI) of strigol is = 10

<h3>How to calculate HDI:</h3>

The hydrogen deficiency index is used to measure the number of degree of unsaturation of an organic compound.

Strigol is an example of an organic compound because it contains carbons and hydrogen.

To calculate the HDI using the molecular formula given (C19H20O6) the formula for HDI is used which is:

hdi =  \frac{1}{2} (2c + 2 + n - h - x)

where C = number of carbon atoms = 19

n= number of nitrogen atoms = 0

h= number of hydrogen atoms = 20

X = number of halogen atoms = 0

Note that oxygen was not considered because it forms two bonds and has no impact.

There for HDI =

\frac{1}{2} (2 \times 19 + 2 + 0 - 20 - 0)

HDI=

\frac{1}{2} (40 - 20)

HDI =

\frac{1}{2}  \times 20

HDI = 10

Therefore, the hydrogen deficiency index of strigol is = 10
