Answer:

Option B. Sodium and potassium lose electrons and chlorine gains them

Explanation:

Sodium and Potassium are both group 1 element. They both react with chlorine by losing 1 electron each and the chlorine atom accept the electron.

Sodium chloride(NaCl) can be formed by the equation below:

Na —> Na+ + e-

Cl + e- —> Cl-

Combining both equation together we obtained the following:

Na + Cl + e- —> Na+ + Cl- + e-

Eliminating the e-, we have:

Na + Cl —> Na+Cl-

From the above illustration, we can see that sodium loses electron and chlorine accepts/gain the electron

This is also applicable to potassium chloride as shown below:

K —> K+ + e-

Cl + e- —> Cl-

Combining both equation together we obtained the following:

K + Cl + e- —> K+ + Cl- + e-

Eliminating the e-, we have:

K + Cl —> K+Cl-

we can see also that potassium loses electron and chlorine accepts/gain the electron

Therefore, the correct answer to the question is option B

When the fish-tank water has a pH of 8.0, the hydronium ion concentration is 1.0 × 10-8 mole per liter. What is the hydronium io
Oduvanchick [21]
You must know and use the formula for pH.


pH = - log [H3O+], where [H3O+] is the molar concentration of hydronium ion.


So, when pH is 8.0 => 8.0 = - log [H3O+] and you can use antilogarithm (the inverse function of logarithm) to find [H3O+], in this way:


[H3O+] = 10^-8 = 1 * 10 ^-8 M


When, pH = 7.0 =>

7.0 = - log [H3O+] => [H3O+] = 1 * 10^ -7 M


Answer: 1*10^-7 mole / liter

Lithium hydroxide reacts with hydrobromic acid(HBr) to produce lithium bromide and water. If you
sweet-ann [11.9K]

Answer:

3.00 moles of Lithium bromide will be produced

Explanation:

The reaction that takes place is:

  • LiOH + HBr → LiBr + H₂O

By looking at the reaction equation, we can see that<em> the reaction of 1 mol of lithium hydroxide (LiOH) produces 1 mol of lithium bromide (LiBr).</em> Thus, 3.00 moles of LiOH would conversely produce 3.00 moles of LiBr.

Serjik [45]

Answer: Esta tendencia es tan regular que el poder de combinación, o valencia, de un elemento se definió una vez como el número de átomos de hidrógeno unidos al elemento en su hidruro. El hidrógeno es el único elemento que forma compuestos en los que los electrones de valencia están en la capa n = 1.

What is the speed of light?can a object move in speed of light?​
timurjin [86]

Answer:

The speed of light is the speed at which light travels. No, an object cannot move at the speed of light.  

Explanation:

The speed of light is 186,000 miles per second. An object with mass cannot move at the speed of light since it would take an infinite amount of energy to achieve that velocity, since only massless particles can travel at the speed of light. Also, you would have to factor in air friction, meaning even if an object were to reach such high speeds, it would instantly disintegrate.
