Explain why you cannot just take away a proton to make a halogen negative.

Ilia_Sergeevich [38]

The force that holds protons and neutrons together is too strong to overcome.

<h3>Explanation</h3>

Consider the location of the particles in an atom.

Electrons are found outside the nucleus.
Protons and neutrons are found within the nucleus.

Protons carry positive charges and repel each other. The nucleus will break apart without the strong force that holds the protons and neutrons together. This force is much stronger than the attraction between the nucleus and the electrons. X-rays are energetic enough for removing electrons from an atom. However, you'll need a collider to remove protons from a stable nucleus. You could well have ionized the atom with all that energy.

Also, changing the number of protons per nucleus will convert the halogen atom to an atom of a different element. Rather than making the halogen negative, removing a proton will convert the halogen atom to the negative ion of a different element.

C=h/[M(T2-T1)] solve for T1

vodka [1.7K]

Explanation:

This is expressing as a subject of a formula of a specie.

This equation is used in solving for specific heat capacity of a material;

equation:

c = $\frac{h}{M(T2 - T1)}$

First cross multiply:

c[M(T2 - T1)] = h

Then multiply both sides by $\frac{1}{c }$ :

$\frac{1}{c }$ x c[M(T2 - T1)] = $\frac{1}{c }$ x h

M(T2 - T1) = $\frac{h}{c}$

Multiply both sides by $\frac{1}{M}$

$\frac{1}{M}$ x M(T2 - T1) = $\frac{1}{M} x \frac{h}{c}$

T2 - T1 = $\frac{h}{Mc}$

Now rearrange to produce;

T1 = T2 + $\frac{h}{Mc}$

2C_H. + 702 — 400, + 6H2O

astra-53 [7]

Balanced Eqn

By the Balanced eqn

60g ethane requires 7x32= 224g oxygen

here ethane is in excess.oxygen will be fully consumed

hence

300g oxygen will consume

⋅

300

224

80.36

ethane

leaving (270-80.36)= 189.64 g ethane.

By the Balanced eqn

60g ethane produces 4x44 g CO2

hence amount of CO2 produced =

⋅

80.36

235.72

and its no. of moles will be

235.72

=5.36 where 44 is the molar mass of Carbon dioxide
