There is no gaseous product when NaNO3 reacts with 6M HCl.
We must note that gas evolution is one of the signs that a chemical reaction has taken place. Hence, we must consider the options and look out for an option in which reaction with HCl does not lead to a gaseous product. This is the option that does not lead to evolution of a gas.
Let us consider the reaction; NaNO3(s) + HCl(aq) ---> NaCl(s) + HNO3(aq), there is no gaseous product hence NaNO3 does not result in gas evolution upon addition of 6M HCl.
Missing parts;

(A) Al
(B) Zn
(C) K2CO3
(D) NaNO3

Answer:
[ HClO₃] = 1.93M
Explanation:
X % by mass, means that in 100 g of solution, we have X g of solute.
In this case, 14.1 g of HClO₃ are contained in 100 g of solution.
Density always referrs to solution. Let's calculate the volume of solution.
Solution density = Solution mass / Solution volume
1.1690 g/mL = 100 g / Solution volume
Solution volume = 100 g /1.1690 g/mL → 86.2 mL.
For molarity we must get moles of solute and volume of solution (L), because molarity is mol/L
Let's convert the mL of solution in L
86.2 mL . 1L / 1000mL = 0.0862 L
Now, let's determine the moles of solute. (Mass / Molar mass)
14.1 g / 84.45 g/mol = 0.167 moles
Molarity is mol/L → 0.167 moles / 0.0862 L = 1.93M
Answer:
Its in the Explanation
Explanation:
Here's what I got.
Aluminium-27 is an isotope of aluminium characterized by the fact that is has a mass number equal to
27
.
Now, an atom's mass number tells you the total number of protons and of neutrons that atom has in its nucleus. Since you're dealing with an isotope of aluminum, it follows that this atom must have the exact same number of protons in its nucleus.
The number of protons an atom has in its nucleus is given by the atomic number. A quick looks in the periodic table will show that aluminum has an atomic number equal to
13
.
This means that any atom that is an isotope of aluminum will have
13
protons in its nucleus.
Since you're dealing with a neutral atom, the number of electrons that surround the nucleus must be equal to the number of protons found in the nucleus.
Therefore, the aluminium-27 isotope will have
13
electrons surrounding its nucleus.
Finally, use the known mass number to determine how many neutrons you have

Answer:
Solid:- Particles vibrate in a rigid structure and do not move relative to their neighbors.
Liquid:- It takes the shape of its container but keeps a constant volume.
Gas:- Particles move rapidly and independently of each other.
Plasma:- It is the most common state of matter in the universe.
Explanation:
Solids are one of the three states of matter and, unlike liquids or gases, they have a definite shape that is not easy to change. Different solids have particular properties such as stretch, STRENGTH, or hardness that make them useful for different jobs.
A liquid is a nearly incompressible fluid that conforms to the shape of its container but retains a (nearly) constant volume independent of pressure
Gas is a state of matter that has no fixed shape and no fixed volume. Gases have lower density than other states of matter, such as solids and liquids. When more gas particles enter a container, there is less space for the particles to spread out, and they become compressed. The particles exert more force on the interior volume of the container.
A plasma is a gas that has been energized to the point that some of the electrons break free from, but travel with, their nucleus.
