2.14g of sodium sulfide react with excess hydrochloric acid to form sodium chloride and dihydrogen sulfide.
BALANCE IT TO AN EQUATION
Answer:
2.14 Na2S + 1.99 HCl ----> 3.20 NaCl + 0.935 H2S
Explanation:
The Balanced equation is
Na2S + 2HCl = 2NaCl + H2S
As we can see -
78.0452 g/mol of sodium sulfide reacts with 2 mole of HCl.
Mass of one mole of HCl = 36.458 g/mol
So, 78.0452 g/mol of sodium sulfide reacts with 2* 36.458 g/mol of HCL to produce 2* 58.44 g of NaCl and 34.1 g/mol of H2S
Thus,
2.14g of sodium sulfide will react with (2* 36.458/78.0452)* 2.14 of HCl
2.14g of sodium sulfide will react with 1.99 g of HCl
2.14 Na2S + 1.99 HCl ----> (2* 58.44/78.0452) *2.14 NaCl + (34.1/78.0452) * 2.14 H2S
2.14 Na2S + 1.99 HCl ----> 3.20 NaCl + 0.935 H2S

Answer:
[tex]p=13330kg*\frac{m}{2}[/tex]
Explanation:
Hello there!
In this case, since the momentum of any body is calculated by multiplying the mass and the velocity:
[tex]p=m*v[/tex]
We simply need to multiply the 215 kg of the motorcycle by the velocity it has, 62 m/s to obtain:
[tex]p=215kg*62m/s\\\\p=13330kg*\frac{m}{2}[/tex]

Describe the law of conservation of mass in your own words *DO IT IN YOUR OWN WORDS PLEASE*
Answer:
Chemical reactions and physical transformations do not create or destroy mass in an isolated system, according to the law of conservation of mass. The mass of the products in a chemical reaction must equal the mass of the reactants, according to the conservation of mass law. The law of conservation of mass can be used to solve for unknown masses, such as how much gas is consumed or produced during a reaction.
Helium only has two valence electrons and is a stable atom. How is this possible when atoms
need 8 valence electron to become stable?
Answer:
Explanation:
Helium (He) is similar in that it, too, only has room for two electrons in its only valence shell. Hydrogen and helium have only one electron shell. The first shell has only one s orbital and no p orbital, so it holds only two electrons. Therefore, these elements are most stable when they have two electrons.

write a paragraph to explain how the transformation of water from one state of matter to another is important for the water cycle
In order for us to have water to drink, it first needs to go through a process called the water cycle. And in that water cycle there’s a process called evaporation. Evaporation is the process by which water changes from a liquid to a gas. In order for it to rain we need clouds and clouds are made of water. The water is heated causing water molecules to convert into gas, that gas then goes through a process called condensation creating clouds. At some point those clouds will be full of water, and all that water will then cause the cloud to release the water molecules causing rain.
The water cycle shows the continuous movement of water within the Earth and atmosphere. It is a complex system that includes many different processes.
Liquid water evaporates into water vapor, condenses to form clouds, and precipitates back to earth in the form of rain and snow.There are four main parts to the water cycle:
Evaporation, Convection, Precipitation and Collection.
Evaporation is when the sun heats up water in rivers or lakes or the ocean and turns it into vapor or steam.
The water vapor or steam leaves the river, lake or ocean and goes into the air.

Explain ocean floor spreading and how this process is related to the mid-ocean ridge
Answer:
Seafloor spreading is a process that occurs at mid-ocean ridges, where new oceanic crust is formed through volcanic activity and then gradually moves away from the ridge.
Explanation:
Mid-ocean ridges and seafloor spreading can also influence sea levels. As oceanic crust moves away from the shallow mid-ocean ridges, it cools and sinks as it becomes more dense. ... Seafloor spreading proves that the ocean itself is a site of tectonic activity.

A chemist uses hot hydrogen gas to convert chromium(III) oxide to
pure chromium. How many grams of hydrogen are needed to
convert 76 grams of chromium(III) oxide, Cr203?
Answer: 3.024 g grams of hydrogen are needed to convert 76 grams of chromium(III) oxide, [tex]Cr_{2}O_{3}[/tex]
Explanation:
The reaction equation for given reaction is as follows.
[tex]Cr_{2}O_{3} + 3H_{2} \rightarrow 2Cr + 3H_{2}O[/tex]
Here, 1 mole of [tex]Cr_{2}O_{3}[/tex] reacts with 3 moles of [tex]H_{2}[/tex].
As mass of chromium (III) oxide is given as 76 g and molar mass of chromium (III) oxide [tex](Cr_{2}O_{3})[/tex] is 152 g/mol.
Number of moles is the mass of substance divided by its molar mass. So, moles of [tex]Cr_{2}O_{3}[/tex] is calculated as follows.
[tex]No. of moles = \frac{mass}{molar mass}\\= \frac{76 g}{152 g/mol}\\= 0.5 mol[/tex]
Now, moles of [tex]H_{2}[/tex].given by 0.5 mol of [tex]Cr_{2}O_{3}[/tex] is calculated as follows.
[tex]0.5 mol Cr_{2}O_{3} \times \frac{3 mol H_{2}}{1 mol Cr_{2}O_{3}}\\= 1.5 mol H_{2}[/tex]
As molar mass of [tex]H_{2}[/tex] is 2.016 g/mol. Therefore, mass of [tex]H_{2}[/tex] is calculated as follows.
[tex]No. of moles = \frac{mass}{molar mass}\\1.5 mol = \frac{mass}{2.016 g/mol}\\mass = 3.024 g[/tex]
Thus, we can conclude that 3.024 g grams of hydrogen are needed to convert 76 grams of chromium(III) oxide, [tex]Cr_{2}O_{3}[/tex].

A sample of krypton occupies 15.0 L at a pressure of 2.1 atm. Use Boyle's Law to find the pressure of the krypton when the volume is decreased to 4L.
Answer:
7.5 atm
Explanation:
Given that,
Initial volume, V₁ = 15 L
Pressure, P₁ = 2.1 atm
Final volume, V₂ = 4L
We need to find the final pressure. The mathematical relation between volume and pressure is given by :
[tex]\dfrac{V_1}{V_2}=\dfrac{P_2}{P_1}\\\\P_2=\dfrac{V_1P_1}{V_2}\\\\P_2=\dfrac{15\times 2}{4}\\\\P_2=7.5\ atm[/tex]
So, the final pressure is equal to 7.5 atm.
