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:

According 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.

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.

in case you mean greenhouse gases they are increasing due to the result of human activities in relation to fossil fuels. the concentration of greenhouse gases also increases due to deforestation. the concentration increases as more is entering the atmosphere than it is being removed.

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.

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.

Answer:

The answer is D. Due to the rotation of earth being a cause is true.

Explanation:

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 %.
