When a bunsen burner is properly adjusted, the flame look like outer violet and inner blue colour.

<h3>What is the clolur of flame?</h3>

When a burner is properly adjusted the flame should have an outer violet oxidizing flame and an inner blue reducing flame. The temperature of blue colour is 15000 degree Celsius whereas the cool region outside the blue has 3000C temperature.

So we can conclude that When a bunsen burner is properly adjusted, the flame look like outer violet and inner blue colour.

How many grams are there in 7.4 x 1023 molecules of H2SO4?
bazaltina [42]

7.4x10^23 = molecules of silver nitrate sample  

6.022x10^23 number of molecules per mole (Avogadro's number)  

Divide molecules of AgNO3 by # of molecules per mol  

7.4/6.022 = 1.229 mols AgNO3 (Sig Figs would put this at 1.3)  

(I leave off the x10^23 because they both will divide out)  

Use your periodic table to find the molar weight of silver nitrate.  

107.868(Ag) + 14(N) + 3(16[O]) = 169.868g/mol AgNO3  

Now multiply your moles of AgNO3 with your molar weight of AgNO3  

1.229mol x 169.868g/mol = 208.767g AgNO3

A molecule has one carbon-carbon double bond and four monovalent atoms or groups. How many different cis-trans isomers exist for
Lena [83]

There can be two cases

Case 1:

When a molecule has one carbon-carbon double bond and four monovalent atoms or groups in which two atoms on same carbon are different, there will be 2 isomers, one cis and one trans.

Case 2:

When a molecule has one carbon-carbon double bond and four monovalent atoms or groups where both atoms attached to the same carbon are same, there will be no geometrical isomerism.

As based on priority, there will be only two orientations possible , in which same priority atoms are on the same side that is cis and if they are on the opposite side that is trans.

Which term refers to a universal fact sometimes based on mathematical equations?
V125BC [204]
<span>The answer is scientific law. This continuously relates in the same circumstances, and suggests that there is a fundamental association connecting its elements. Truthful and well-confirmed statements like "Mercury is liquid at STP" are measured too exact to be suitable as scientific laws. </span>

What is meant when it is stated that WATER can ""Ionize"" to a certain extent? What are the products that are formed when water
never [62]

Answer:

Ionization is defined as the process by which the atoms accept or donate electrons and form positively or negatively charged species, called ions.

The ionization of water is known as the self-ionization or autoionization of water. This process involves the deprotonation of a water molecule and protonation of another water molecule to give hydroxide ion and hydronium ion, which exist in the state of chemical equilibrium.

H₂O + H₂O ⇌ H₃O⁺ + OH⁻

The pH of pure water is 7, neutral.
