<u>Answer:</u>

The scientists predict the polarity of molecules and the distribution of non polar and polar molecules by finding out the net dipole moment of the molecular structure.

<u>Explanation:</u>

The net value of dipole moment is found out with the help of finding the bond angle between the atoms of the given molecule along with the distance between the atoms and the charge on the atoms of the molecule.

This will be applied in the appropriate formula which tells whether the molecule is polar or non polar.

The pressure of a 609.64 gram sample of F2 in a 88.84 L container is measured to be 2770.96 torr. What is the temperature of thi
Oxana [17]

Answer : The temperature of the gas is, 245.9 K

Explanation :

To calculate the temperature of gas we are using ideal gas equation:

PV=nRT\\\\PV=\frac{w}{M}RT

where,

P = pressure of gas = 2770.96 torr = 3.646 atm

Conversion used : (1 atm = 760 torr)

V = volume of gas = 88.84 L

T = temperature of gas = ?

R = gas constant = 0.0821 L.atm/mole.K

w = mass of gas = 609.64 g

M = molar mass of F_2 gas = 38 g/mole

Now put all the given values in the ideal gas equation, we get:

(3.646atm)\times (88.84L)=\frac{609.64g}{38g/mole}\times (0.0821L.atm/mole.K)\times (T)

T=245.9K

Therefore, the temperature of the gas is, 245.9 K

What are some positive applications for allelotoxin?
pogonyaev

Positive applications for allelotoxin is that it prevents plants from enduring any type of competition with other species.

<h3>What is Allelopathy?</h3>

This is the process in which a plant inhibits the growth of another through a secretion of a chemical which is referred to as allelotoxin.

This technique however reduces biodiversity which isn't ideal so as to prevent organisms from going extinct and also reduces adaptation or evolution due to the reduced or non growth of the plant species which are affected.

A common example is  the sorghum plant preventing of the growth of weeds thereby resulting in the most appropriate choices for the positive applications of allelotoxin.

What is the chemical formula for nickel (ii) hypochlorite?
gtnhenbr [62]
The   chemical  formula  of  nickel  (ii) hypochlorite  is Ni(CIO)2. Nickel (II)   has a  charge  of  +2  while (CIO-)  which  is  a  poly  atomic ion  of  chlorine and  oxygen has  a  charge  of   -1.  After  balancing  the  charge  of    nickel with  that   of  CIO- you  get  the  chemical  formula  as  Ni(CIO)2.
