A reaction of 17.0 g of ammonia with 26.6 g of chlorine gas
produces 3.50 g of nitrogen. What mass of ammonium chloride
is produced in the reaction?
Answer: if doing it on ck-12 the answer is 40.1
Explanation:
There are produced 40.1 grams of ammonium chloride (NH₄Cl) in the reaction between 17.0 g of ammonia (NH₃) and 26.6 g of chlorine gas (Cl₂).
The reaction between ammonia and chlorine gas is the following:
8NH₃ + 3Cl₂ → 6NH₄Cl + N₂
Initially, we have:
[tex]m_{NH_{3}}[/tex]: mass of ammonia = 17.0 g[tex]m_{Cl_{2}}[/tex]: mass of chlorine gas = 26.6 g[tex]m_{N_{2}}[/tex]: mass of nitrogen = 3.50 gAccording to the conservation of mass, matter cannot be created or destroyed, only can be transformed, so the mass of the reactants must be equal to the mass of the products.
The mass of ammonium chloride produced is:
[tex] m_{r} = m_{p} [/tex]
[tex] m_{NH_{3}} + m_{Cl_{2}} = m_{NH_{4}Cl} + m_{N_{2}} [/tex]
[tex] 17.0 g + 26.6 g = m_{NH_{4}Cl} + 3.50 g [/tex]
[tex] m_{NH_{4}Cl} = 17.0 g + 26.6 g - 3.50 g = 40.1 g [/tex]
Therefore, 40.1 grams of ammonium chloride are produced in the reaction.

what is the mass in grams of 0.250 mol of the common antacid calcium carbonate?
Answer:
Molar mass CaCO3 = 100 g/mol
Explanation:
So if we have 75 four or 5 g of the sample And there is 25.8 Percent calcium carbonate by mass. That's 25.8 g of calcium carbonate In 100 g of the sample. I'll do the most application at the end. Um And then if we know the grams of calcium carbonate, well, just reverse the conversion factor. Yeah, 100 g of the sample contains 25 0.8 grams of calcium carbonate. And when we do this, multiplication division, for part a 75.45 Times 25.8, divided by a 1000 Uh 23 significant figures is 1.9 five g of calcium carbonate. Mhm. And then for part B 18.8 times 100 Divided by 25.8 is 2. 3 significant figures 72 0.9 grams. Mhm of the sample. Yeah.

write a brief description explaining the term "luminous" to a classmate
Answer:
Plz mark as brainlist
luminous is relating to light as it is perceived by the eye, rather than in terms of its actual energy.
A brief description explaining the term "luminous" to generating or reflecting brilliant light, particularly at night: luminous attire. The bright glow of laptops illuminated the library.
What is luminous ?Luminous objects are things like the sun that produce or radiate light on their own. Others include a torch, an electric lamp, etc. Non-bright objects are those that don't emit any light of their own and can only be seen when light from a luminous source reflects off of them. Moon, a chair, a painting, etc. are a few examples.
Luminous objects are defined as those that produce their own light. Just the sun emits its own light; all other things only reflect light that is incident upon them.
The presence of luminous items produces the feeling of light. These things are visible because they independently emit light. As an illustration, consider the Sun, the stars, lightbulbs, torches, tube lights, candles, and so on.
Thus,the term "luminous" to generating or reflecting brilliant light, particularly at night: luminous attire. The bright glow of laptops illuminated the library.

20 ml of a solution of sucrose contains 850 mg of sucrose. What is the weight/volume percentage concentration of this solution in g/ml%
Explanation:
weight/volume percentage concentration = (mass in g ÷ volume) × 100
= (0.850 g ÷ 20 ml) × 100
= 4.25 g/ml %
∴ the weight/volume percentage concentration of the sucrose solution is 4.25 g/ml %.

Why the melting point of sodium chloride is higher than naphthalene
Answer:
This is because sodium chloride has electrostatic forces of attraction and thus this tends to hold the the sodium and chloride ions very strongly and thus responsible for the high melting point. Sodium chloride is very soluble in water than naphthalene.
Explanation:
This is because sodium chloride electrostatic forces of attraction ad thus this tend to hold the sodium and chlorine ions very strongly thus it is responsible for the high melting point.
What is the difference between variable and fixed costs?
Answer:
Variable costs are costs that change depending on the amount of the product you are providing. Fixed costs On the other hand are costs that are the same no matter how much of the product or service you are providing. Fixed costs are also called overhead or fixed operating costs.
