Answer:

a. hydrofluoric acid  - Specialized spill kit is needed

b. special mercury  - Specialized spill kit is needed

c. special phosphoric acid  - General spill kit is Sufficient

d. acetone  - General spill kit is Sufficient

e. general methanol - General spill kit is Sufficient

Explanation:

a. hydrofluoric acid  -

It is a weak acid , and very corrosive therefore , it need Specialized spill kit

b. special mercury  -

At the room temperature , liquid mercury evaporates. But Small amount of mercury can cause harm so , Specialized spill kit is needed

c. special phosphoric acid  -

It is relatively compared to others is a week acid , therefore General spill kit is Sufficient

d. acetone  -

At the room temperature , acetone evaporates, therefore General spill kit is Sufficient

e. general methanol -

At the room temperature , methanol evaporates, therefore General spill kit is Sufficient

Please help me balance:<br>_NaNO3 + _PbO_ ➡️ Pb(NO3)2 + _Na2O
KengaRu [80]

Answer:

The balanced reaction is given by,

2NaN(O)3 + PbO ⇒ Pb(NO3)2 + Na2O

Explanation:

The reaction is as given.

Lets count the number of each elements in the reaction.

<em>In reactant side, number of sodium atoms are 1 , lead are 1, nitrogen are 1 and oxygen are 4.</em>

<em>in product side, number of sodium atoms are 2 , lead are 1 , nitrogen are 2 and oxygen are 7.</em>

<em>So we need to balance sodium and oxygen atoms in the reaction.</em>

<em>There is deficient of sodium and oxygen atoms on reactant side</em>.

Thus, multiply (NaNO3) by 2.

<em>Thus, sodium atoms become 2 , nitrogen 2 and oxygen 6. Total 7 oxygen atoms.</em>

Thus, the balanced reaction is,

2NaN(O)3 + PbO ⇒ Pb(NO3)2 + Na2O

Sodium is going in group 1, period 3. It contains A. One valence electron in its 3rd energy shell B three valence electron in it
topjm [15]

Answer:

The correct answer is option A, that is, one valence electron in its third energy shell and option C, that is, 11 electrons and 11 protons.

Explanation:

The outermost electrons and the ones that take part in the process of bonding are termed as valence electrons. The atomic number of sodium is 11, thus, it possesses 11 protons and the atoms are neutral so it suggests that sodium has 11 electrons. By electronic configuration, it can be seen that in sodium, two electrons are present in the first shell, 8 in the second, and only one electron in the third shell, that is, 2.8.1. The electron present in the third shell is the valence electron.
