c. remains the same
The atomic number will only increase if there is an increase in protons.
The average atomic mass (or amu) will increase if the number of neutrons increase.
If an element's mass is greater or less than the average atomic mass, it is known as an isotope.

Since the atomic number of an element consists of neutrons and also electrons, we can conclude that since the number of neutrons are increasing, the atomic number will also increase. That is called an isotope (when the number of neutrons differ)

Final answer:- b. Increases

How many protons, neutrons, and electrons does sodiums neutral atom have? Plz help.

rusak2 [61]

Answer:

So for your question, the Periodic Table tells us that sodium has an Atomic Number of 11, so there are 11 protons and 11 electrons. The Periodic Table tells us that sodium has an Atomic Mass of ≈23. So there are 23 - 11 = 12 neutrons.

Th actual yield of the reaction is 24.86 g

We'll begin by calculating the theoretical yield of the reaction.

2Na + Cl₂ → 2NaCl

Molar mass of Na = 23 g/mol

Mass of Na from the balanced equation = 2 × 23 = 46 g

Molar mass of NaCl = 23 + 35.5 = 58.5 g/mol

Mass of NaCl from the balanced = 2 × 58.5 = 117 g

From the balanced equation above,

46 g of Na reacted to produce 117 g of NaCl.

Therefore,

11.5 g of Na will react to produce = (11.5 × 117) / 46 = 29.25 g of NaCl.

Thus, the theoretical yield of NaCl is 29.25 g.

Finally, we shall determine the actual yield of NaCl.

Percentage yield = 85%

Theoretical yield = 29.25 g

Actual yield =?

Actual yield = Percent yield × Theoretical yield

Actual yield = 85% × 29.25

Actual yield = 0.85 × 29.25 g

Actual yield = 24.86 g

Which description is a characteristic of a base?

MA_775_DIABLO [31]

I am pretty sure it is B. If it turns litmus paper red it is acidic. The other 2 make no sense.
I might be wrong tho.
Hope that helped☺️

Suppose that 10.0 L of Carbon Dioxide gas are produced by this reaction, 4C3H5N3O9 -> 12 CO2 + 10H2O + 6N2 +O2, at a temperat

siniylev [52]

The mass of nitroglycerin : 34.52 g

<h3>Further explanation</h3>

Reaction

4C₃H₅N₃O₉ ⇒ 12 CO₂ + 10H₂O + 6N₂ +O₂

Volume = 10 L

Temperature = -5°C=268 °K

Pressure = 1 atm

mol of CO₂ (ideal gas) :

$\tt n=\dfrac{PV}{RT}\\\\n=\dfrac{1\times 10}{0.082\times 268}\\\\n=0.455$

mol ratio C₃H₅N₃O₉ : mol CO₂= 4 : 12, so mol C₃H₅N₃O₉ :

$\tt \dfrac{4}{12}\times 0.455=0.152$

mass C₃H₅N₃O₉ (MW=227,0865 g/mol):

$\tt 0.152\times 227.0865=\boxed{\bold{34.52~g}}$
