Why is water considered to be polar?

Chemistry
1 answer:
Vera_Pavlovna [14]3 years ago
3 0

Answer: Water is a polar molecule since it has an unequal sharing of electrons. Water is chemically written as H2O meaning it consists of hydrogen and oxygen atoms. Hydrogen is number one in the Periodic Table whereas oxygen is number 14. As a result, the configuration of oxygen is 2.8.4 while that of hydrogen is 1. When two hydrogen atoms combine with one oxygen atom, two out of the four electrons in oxygen form the strong bond in water. The resulting effect is that there is an unequal sharing of electrons since two electrons remain unused. The hydrogen end becomes partially positive while the oxygen end is partially negative. Furthermore, the oxygen atom has a stronger attractive force hence drawing more atoms to it. Subsequently, there arises a charge imbalance within the molecule. Besides water, hydrogen fluoride is also a polar molecule.

10 atoms of aluminum reacts with 6 molecules of oxygen gas to produce aluminum oxide. 4 Al + 3 O2 ––> 2 Al2O3 What is the exc
Mrrafil [7]

The excess reactant is Aluminum.

<u>Explanation:</u>

We have to write the balanced equation as,

4 Al+ 3 O₂ → 2 Al₂O₃

According to the molar ratio 4: 3, from the given balanced equation, we can say that 4 atoms of Al reacted with 3 molecules of oxygen.

Given that 10 atoms of aluminum reacts with 6 molecules of oxygen, as per the ratio only 8 atoms of Aluminum is required to react with 6 molecules of oxygen, so excess reactant is Aluminum.

Are the products and balancing correct for this Equation:
goldfiish [28.3K]

Answer:

False

Explanation:

Chemical reaction equation:

                   C₅H₁₂ + 8O₂ → 2CO₂ + 6H₂O

Most chemical reactions obey the law of conservation of mass. By so doing, the number of chemical elements on both sides of the expression must be balanced.

                 Reactants                                          Products

C                    5                                                           4

H                  12                                                           12

O                 16                                                             10

We see that for C and O, the number of atoms on both sides of the expression differs and so, it is not balanced.

A 45 kg box is sitting on a window ledge 2.0 m above the ground. What is the potential energy of the box?
Travka [436]

Answer:

<h3>The answer is 900 J</h3>

Explanation:

The potential energy of a body can be found by using the formula

PE = mgh

where

m is the mass

h is the height

g is the acceleration due to gravity which is 10 m/s²

From the question we have

PE = 45 × 10 × 2

We have the final answer as

<h3>900 J</h3>

Hope this helps you

How many moles of ZnCl, will be produced from 23.0 g of Zn, assuming CuCl, is available in excess?
Dennis_Churaev [7]

Answer:

23 g of Zn will produce 0.352 mole of zinc chloride.      

Explanation:

Given data:

mass of Zn = 23 g

Moles of ZnCl = ?

Solution:

Chemical equation:

2Zn + CuCl₂ → 2ZnCl + Cu

Number of moles of Zn:

<em>Number of moles of Zn = mass/ molar mass</em>

Number of moles of Zn = 23 g / 65.38 g/mol

Number of moles of Zn = 0.352 mol

now we will compare the moles of ZnCl with Zn because it is limiting reactant.

                         Zn       :      ZnCl  

                         2         :        2

                         0.352 :        0.352

So 23 g of Zn will produce 0.352 mole of zinc chloride.
