What types of star can explode in a supernova
horrorfan [7]
For a star to explode as a Type II supernova, it must be at several times more massive than the sun<span> (estimates run from eight to 15 solar masses). Like </span>the sun<span>, it will eventually run out of hydrogen and then helium fuel at its core. However, it will have enough mass and pressure to fuse carbon.

Why do different elements make different color flames when you burn them?
Dovator [93]
When you heat an atom, some of its electrons are "excited* to higher energy levels. When an electron drops from one level to a lower energy level, it emits a quantum of energy. ... The different mix of energy differences for each atom produces different colours. Each metal gives a characteristic flame emission spectrum.

Oxygen has an electronegativity of 3.5, and carbon has an electronegativity of 2.5. How is charge distributed on an oxygen atom
Aleksandr [31]

Answer:

The oxygen atom has a slightly negative charge.

Explanation:

3.5 - 2.5 = 1

For ionic bond electronegativity should be more than 1.6.

So, O and C do not have whole charge. Electronegativity of O more than C, so electrons slightly moved to the oxygen side.

Which sample would show stronger (intermolecular) attractive forces, the cold water or the hot water?
erik [133]

Answer:

Cold water

Explanation:

A simple way to solve this kind of problems is to keep in mind that:

<em>Solids have stronger intermolecular attractive forces than liquids, and liquids have stronger forces than gases.</em>

Cold water behaves more similarly to solids than hot water. Conversely, hot water behaves more similarly to gases than cold water. Thus, cold water has stronger intermolecular attractive forces than hot water.

Which of the following is not a conjugate acid-base pair? A) NH4+/NH3 B) H30-OH OC) H2SO3/HSO3 D) C2H302-/HC2H302
raketka [301]

Answer : The option (d) is not a conjugate acid-base pair.

Explanation :

According to the Bronsted Lowry concept, Bronsted Lowry-acid is a substance that donates one or more hydrogen ion in a reaction and Bronsted Lowry-base is a substance that accepts one or more hydrogen ion in a reaction.

Or we can say that, conjugate acid is proton donor and conjugate base is proton acceptor.

(a) The equilibrium reaction will be,

NH_4^++OH^-\rightleftharpoons NH_3+H_2O

In this reaction, NH_4^+/NH_3 are act as a conjugate acid-base.

(b) The equilibrium reaction will be,

H_3O^++OH^-\rightleftharpoons H_2O+H_2O

In this reaction, H_3O^+/OH^- are act as a conjugate acid-base.

(c) The equilibrium reaction will be,

H_2SO_3+OH^-\rightleftharpoons HSO_3^-+H_2O

In this reaction, H_2SO_3/HSO_3^- are act as a conjugate acid-base.

(d) The equilibrium reaction will be,

C_2H_3O_2^-+H_2O\rightleftharpoons HC_2H_3O_2+OH^-

In this reaction, C_2H_3O_2^-/HC_2H_3O_2 are act as a conjugate base-acid.

Hence, from this we conclude that, the option (d) is not a conjugate acid-base pair but it is a act as conjugate base-acid.
