C.

If a power line were broken then power would not reach the light. Which is possible.

If a wire to the light or to the box in your house was broken your light would not receive power, therefore not turn on. Again possible.

If the power plant does not produce enough electricity, although unlikely, that would cause you to not be able to turn on your light. Unlikely but it would be true is it happened.

Finally C is not likely, your wires in your house are most likely made of copper but too many conductors in the wire, not only wouldn’t happen, but would most likely not interrupt your light working.

The question asks what is NOT a possible cause. C is the only not possible.

How many valence electrons are there in Se atom?

Lena [83]

Answer:

4 valence electrons

Despite the fact that the word silicon has a ubiquitous affiliation with all things electronic, Si itself is not a good electrical conductor. It has 4 valence electrons, meaning that filling its outer shell it can form a very strong lattice with 4 neighboring Si atoms-with no un-bonded electrons remaining

Calculate the number of moles of magnesium, chlorine, and oxygen atoms in 5.90 moles of magnesium perchlorate, Mg(ClO4)2.

Lady bird [3.3K]

Answer:

5.90, 11.8, 47.2

Explanation:

Let’s remove the parentheses and write the formula as MgCl₂O₈.

We see that 1 mol Mg(ClO₄)₂ contains 1 mol Mg atoms, 2 mol Cl atoms, and 8 mol O atoms.

∴ $\text{Moles of Mg atoms} = \text{5.90 mol Mg(ClO}_{4})_{2} \times \frac{\text{1 mol Mg atoms}} {\text{1 mol Mg(ClO}_{4})_{2}} = \text{5.90 mol Mg atoms}$

$\text{Moles of Cl atoms} = \text{5.90 mol Mg(ClO}_{4})_{2} \times \frac{\text{2 mol Cl atoms}} {\text{1 mol Mg(ClO}_{4})_{2}} = \text{11.8 mol Cl atoms}$

$\text{Moles of O atoms} = \text{5.90 mol Mg(ClO}_{4})_{2} \times \frac{\text{8 mol O atoms}} {\text{1 mol Mg(ClO}_{4})_{2}} = \text{47.2 mol O atoms}$

∴ Mg, Cl, O = 5.90, 11.8, 47.2

Write the name for NaCl

neonofarm [45]

The name for NaCl is Sodium chloride

<h3>Salt and it's examples.</h3>

It is formed by the reaction of acid and base is a neutralisation reaction.

Examples of salt include:

Sodium Chloride or Common Salt (NaCl)

Sodium Hydroxide (NaOH)

Sodium Carbonate or Washing Soda (Na2CO3.10H2O)

Baking Soda or Sodium Bi-carbonate (NaHCO3)

Bleaching Powder or Calcium Hypochlorite.

Therefore another name for salt is common salt.
