The maximum mass of NH₃ that can be formed when 36.52 g of N₂ reacts with 10.62 g of H₂ is 44.35 g
Balanced equationN₂ + 3H₂ —> 2NH₃
Molar mass of N₂ = 14 × 2 = 28 g/mol
Mass of N₂ from the balanced equation = 1 × 28 = 28 g
Molar mass of H₂ = 2 × 1 = 2 g/mol
Mass of H₂ from the balanced equation = 3 × 2 = 6 g
Molar mass of NH₃ = 14 + (3×1) = 17 g/mol
Mass of NH₃ from the balanced equation = 2 × 17 = 34 g
SUMMARY
From the balanced equation above,
28 g of N₂ reacted with 6 g of H₂ to produce 34 g of NH₃
How to determine the limiting reactantFrom the balanced equation above,
28 g of N₂ reacted with 6 g of H₂
Therefore,
36.52 g of N₂ will react with = (36.52 × 6) / 28 = 7.83 g of H₂
From the above calculation, we can see that only 7.83 g out of 10.62 g of H₂ are required to react completely with 36.52 g of N₂.
Therefore, N₂ is the limiting reactant
How to determine the maximum mass of NH₃ producedFrom the balanced equation above,
28 g of N₂ reacted to produce 34 g of NH₃
Therefore,
36.52 g of N₂ will react to produce = (36.52 × 34) / 28 = 44.35 g of NH₃
Thus, the maximum mass of NH₃ obtained from the reaction is 44.35 g

How can objects all be the same size but have a different mass? *help quick*
Answer:
All objects can have the same size but have a different mass!
This is true, although it sounds fake. This is one example, there is a Neutron star, and Neutron stars are as big as a city, but they have a mass which is hundreds of times greater than our sun's mass. Because of them having so much mass, they are also having so much gravitational energy, which makes them also have gravity. They're so small, but have so much mass that they can do much. Even a drop of a neutron star can punch open the earth! It's true, so yes, it is possible for objects the SAME size to be having different masses according to that example.
But let's look on how they can have different mass.
They can have different masses becase of different densities. Put a iron ball inside water, and put an apple as close to the iron ball's side, what happens? The apple floats, becuase the apple's mass is less than the water, and the iron ball's mass is MORE than the water. So, because the iron ball is denser than the apple, that's why, it has more mass than the apple. The apple isn't much dense, it isn't as dense as water or the iron ball. But the iron ball is much more denser than the water. So because of the different material densities of the material, that's why it can have different masses.
Remember to Remember those 2 examples I gave you... (neutron star vs sun, iron ball vs apple on water)

A piece of metal weighing 0.035 kg was submerged in a graduated cylinder containing water. The water level rose from 2.0 mL to 9.0 mL. What is the density in g/mL of the metal
Taking into account the definition of density, the density of the metal is 5 [tex]\frac{g}{mL}[/tex].
What is densityDensity is defined as the property that matter, whether solid, liquid or gas, has to compress into a given space.
In other words, density is a quantity that allows us to measure the amount of mass in a certain volume of a substance.
Then, the expression for the calculation of density is the quotient between the mass of a body and the volume it occupies:
[tex]density=\frac{mass}{volume}[/tex]
From this expression it can be deduced that density is inversely proportional to volume: the smaller the volume occupied by a given mass, the higher the density.
This caseIn this case, the increase in the volume of water in the cylinder is due to the volume of the metal. This means that the volume of the metal can be calculated by taking into account the volume occupied by the water + the metal and the volume occupied by the water alone in the cylinder.
Then, you know that:
Mass= 0.035 kg= 35 g (being 1 kg=1000 g)Volume= Volumen water + the metal - Volume water= 9 mL - 2 mL= 7 mLReplacing in the definition of density:
[tex]density=\frac{35 g}{7 mL}[/tex]
Solving:
density= 5 [tex]\frac{g}{mL}[/tex]
In summary, the density of the metal is 5 [tex]\frac{g}{mL}[/tex].

The type of surface that warms up the slowest is .
Answer:
Answer might be Water...
A surface with a high reflectivity or low heat conductivity typically warms up at the slowest rate. Ice, snow, and some metals, like aluminium, are examples.
A smooth surface is one that doesn't have any ridges or other surface imperfections. It is smooth and devoid of any roughness, dents, or lumps. This kind of surface, which is highly reflective, is frequently seen in materials like glass, polished metal, or plastic. Rough texture: An uneven or irregular texture is indicative of a rough surface. It has lumps, ridges, or other abnormalities that microscopically obstruct the smoothness. Rough surfaces reduce the reflecting qualities of light by scattering it in many directions. Wood, concrete, or coarse fabrics are a few examples of rough surfaces.

Next, you will gradually apply heat to the sugar and observe the effects. Your goal is to identify the point at which sugar begins to melt. To get started, follow these steps. Then, answer the question that follows.
Pour 1 tablespoon of sugar into a cooking pan. Spread it out across the surface of the pan. Place the pan on a stove.
Because all stoves are different, you’ll need to identify your low, medium, and high heat settings before proceeding to step 3.
Use the method below to gradually heat the pan until you see the sugar begin to melt. Once the sugar melts, note how much time has elapsed and the final heat setting. If at any point the pan begins to smoke, immediately turn off the heat source and remove the pan from the heat. Heat the pan for these times and temperatures, stopping when the sugar begins to melt:
5 minutes on low heat
5 minutes on medium-low heat
5 minutes on medium heat
5 minutes on medium-high heat
5 minutes on high heat
When the sugar melts, turn off the stove and remove the pan from the heat. Do not touch the hot pan except by its handle. Use hot pads or oven mitts if the pan’s handle isn’t insulated. Let the pan sit off the heat on a heat-resistant surface until it cools.
Approximately how many minutes did it take for the sugar to melt? What was the final heat setting?
Repeat the process given in part D using salt instead of sugar. Did the salt melt? If so, approximately how many minutes did it take for the salt to melt?
When a high amount of heat is supplied, the sugar melts faster than when a low amount of heat is supplied.
What is melting?The term melting has to do with the breakdown of the bonds that hold the molecules of a substance together. Melting occurs when heat is applied continously to a body.
Now, the time taken for the sugar to melt depends on the amount of heat supplied. In other words, when a high amount of heat is supplied, the sugar melts faster than when a low amount of heat is supplied.

Gold is very malleable. That's what hitting gold with a hammer will do. It tends to shape the gold without destroying it into lots of pieces. A lot of yellow things have that property.

Find the final temperature when 10 grams of aluminum at 130 c mixes with 200 grams of water at 25 c. assume no water is lost as water vapor. specific heat values (c) for aluminum= 0.901 j/g c and water 4.18 j/g c
Answer:
About 26.12 C°
Explanation:
Following q = mc∆t, assuming q is the same
(10g)(130 - T)(0.901j/g*c) = (200.0g)(T - 25)(4.18j/g*c)
T = 26.12
At which temperature does water have particles with a greater average kinetic energy than water with a temperature of 30°C?
77°F
95°F
280K
300K
Answer:
95F
Explanation:
First we convert these temperatures into °C:
77°F = 25°C
95°F = 35°C
280K = 6.85°C
300K = 26.85°C
When temperature increases, water molecules have a greater average kinetic energy ans are more likely to collide with each other.
Out of the 4 temperatures, only 95°F (35°C) is of a higher temperature than 30°C. Hence 95°F is the answer.

Predict and write the formulas for the two products of the reaction of aluminum metal al(s) with the copper(ii) chloride.
Answer:
Cu (s) and AlCl₃ (s)
Explanation:
This reaction can be classified as a single-displacement reaction, aka. a single-replacement reaction. These reactions involve one element swapping out another element in a compound. In this reaction, aluminum is taking the place of copper (ii) in the copper (ii) chloride compound. Aluminum takes the place of copper (ii) specifically because aluminum is more likely form a cation than anion. Copper (ii) serves as a cation in the compound.
Al (s) + CuCl₂ (s) --> Cu (s) + AlCl₃ (s)
The final products are copper (ii) metal and aluminum chloride. The metal of copper (ii) is produced instead of the cation in order to maintain the neutral charge balance of the reaction. The chorine has a subscript of 3 because aluminum usually forms cations of a +3 charge while chlorines form anions with a -1 charge.
The balanced equation is:
2 Al (s) + 3 CuCl₂ (s) --> 3 Cu (s) + 2 AlCl₃ (s)
