Two atoms of the same element are most likely to form

Chemistry
1 answer:
grandymaker [24]3 years ago
7 0

<u>Answer:</u>

<em>Two atoms of the same element are most likely to form Molecule.</em>

<em></em>

<u>Explanation:</u>

F_2,Cl_2,Br_2  ,I_2 are some examples

1 molecule of fluorine contains 2 atoms of Fluorine.

Similarly,

One molecule of chlorine (Cl),  

One molecule of bromine (Br),  

One molecule of iodine  (I)

Each contains two atoms of the same element.  We call these molecules as homodiatomic molecules.

There are 7 diatomic molecules which are as follows,

They are F_2,Cl_2,Br_2,I_2,N_2,O_2 and H_2

In this equation, what should be the coefficients of the reactants and products?
Strike441 [17]

Answer:

C.) The coefficient of iodine is 4, oxygen is 9, and the product is 2

Explanation:

An equation is balanced when there is an equal amount of each element on both sides of a reaction. If the amounts are unequal, you can modify the amount of molecules by adding coefficients.

The unbalanced reaction:

I₂ + O₂ -----> I₄O₉

<u>Reactants</u>: 2 iodine, 2 oxygen

<u>Products</u>: 4 iodine, 9 oxygen

The balanced equation:

4 I₂ + 9 O₂ -----> 2 I₄O₉

Reactants: 8 iodine, 18 oxygen

Products: 8 iodine, 18 oxygen

Remember, coefficients are the numbers placed in front of the molecular formulas. As such, the coefficient of iodine is 4, oxygen is 9, and the product is 2.

A local am radio station broadcasts at a wavelength of 349m, calculate the energy of the wavelength at which it is broadcasting?
Juli2301 [7.4K]

Answer:

E = 5.69x10⁻²⁸m

Explanation:

To solve this question we neeed to convert the wavelength in meters to energy in joules using the equation:

E = hc / λ

<em>Where E is energy in joules, h is Planck's constant = 6.626x10⁻³⁴Js</em>

<em>c is light constant = 3.0x10⁸m/s</em>

<em>And λ is wavelength in meters = 349m</em>

Replacing:

E = 6.626x10⁻³⁴Js*3.0x10⁸m/s / 349m

E = 5.69x10⁻²⁸m

You measure the absorbance of your extracted curcumin solution and realize that the solution is too concentrated. What made you
zepelin [54]

If the absorbance of a solution of curcumin which is too concentrated is measured, the absorbance will be unusually high.

Spectrometry measures the interaction of light with molecules. The absorbance refers to how much light that interacts with molecules of the substance. The more the concentration of the substance the higher the absorbance of the solution.

Hence, if  the absorbance of a solution of curcumin which is too concentrated is measured, the absorbance will be unusually high. An unusually high absorbance tells us that the solution is too concentrated.

What is the molarity of a nitric acid solution if 43.13 mL 0.1000 M KOH solution is needed to neutralize 30.00 mL of the acid so
Leno4ka [110]

Answer:

0.144M

Explanation:

First, let us write a balanced equation for the reaction. This is illustrated below:

HNO3 + KOH —> KNO3 + H20

From the equation,

nA = 1

nB = 1

From the question given, we obtained the following:

Ma =?

Va = 30.00mL

Mb = 0.1000M

Vb = 43.13 mL

MaVa / MbVb = nA/nB

Ma x 30 / 0.1 x 43.13 = 1

Cross multiply to express in linear form

Ma x 30 = 0.1 x 43.13

Divide both side by 30

Ma = (0.1 x 43.13) /30 = 0.144M

The molarity of the nitric acid is 0.144M
