Answer:

Ammonium chloride and slacked lime

Explanation:

We can generate ammonia gas in the research centre by slowly heating ammonium chloride (NH4Cl) and slaked lime [Ca(OH)2]. Ammonia gas is lighter than air, requiring its accumulation by the descending displacement of air.

Answer:

the correct answer is A

Explanation:

I took the test!

Answer:

A probably because its ionic

Answer:

Thomson's plum pudding model of the atom had negatively-charged electrons embedded within a positively-charged "soup." Rutherford's gold foil experiment showed that the atom is mostly empty space with a tiny, dense, positively-charged nucleus. Based on these results, Rutherford proposed the nuclear model of the atom.

Answer:

Alright, the first thing we have to do is to balance the chemical equation

2Na3N -----> 6Na + 1N2

We have 60g of Na3N, we convert them into moles by dividing the mass of the compound by the molar mass.

Molar mass of Na3N = (22.98 x 3) + (14) = 82.94g/mol

  60          =  0.72341451651 moles of Na3N

82.94

Now because we did the balanced equation, we know the mole to mole ratio of Na3N to N2 would be 2:1, so in order to get the moles of N2 you have to divide the moles of Na3N by 2

0.72341451651 moles/2 = 0.361707258 moles of N2

Now that we have the moles of N2, we just have to determine the mass of it in grams. In order to do that, just multiply the moles by the molar mass of N2 (28g/mol)

0.361707258 x 28 = 10.13g of N2

Therefore the decomposition of 60g of Na3N would result in 10.13g of N2 (nitrogen gas)

Answer:

Approximately [tex]41.2\; {\rm ^{\circ} C}[/tex].

Explanation:

Let [tex]t\; {\rm ^{\circ} C}[/tex] be the final temperature of the water and the iron.

Temperature of the water would be increase by [tex](t - 38.00)\; {\rm ^{\circ} C}[/tex].

Temperature of the iron would be reduced by [tex](100.0 - t)\; {\rm ^{\circ} C}[/tex].

Let [tex]c[/tex] denote the specific heat of each material. Let [tex]m[/tex] denote the mass of the material. For a temperature change of [tex]\Delta t[/tex], the energy change involved would be:

[tex]Q = c\, m \, \Delta t[/tex].

The energy that the water need to absorb would be:

[tex]\begin{aligned}& Q(\text{water, absorbed}) \\ =\; & c(\text{water}) \, m(\text{water})\, \Delta t (\text{water}) \\ =\; & 4.181\; {\rm J \cdot g^{-1} \cdot K^{-1}} \times 50\; {\rm g} \times (t - 38.00)\; {\rm ^{\circ} C} \\ =\; & (209.05\, t - 7943.9)\; {\rm J} \end{aligned}[/tex].

The energy that the iron would need to release would be:

[tex]\begin{aligned}& Q(\text{iron, released}) \\ =\; & c(\text{iron}) \, m(\text{iron})\, \Delta t (\text{iron}) \\ =\; & 0.45\; {\rm J \cdot g^{-1} \cdot K^{-1}} \times 25.0\; {\rm g} \times (100.0 - t)\; {\rm ^{\circ} C} \\ =\; & (1125 - 11.25 \, t)\; {\rm J} \end{aligned}[/tex].

Since this calorimeter is insulated, the energy that the iron had released would be equal to the energy that the water had absorbed:

[tex]Q(\text{water, absorbed}) = Q(\text{iron, released})[/tex].

[tex]209.05\, t - 7943.9 = 1125 - 11.25\, t[/tex].

[tex]t \approx 41.2[/tex].

Thus, the final temperature of the water and the iron would be approximately [tex]41.2\; {\rm ^{\circ} C}[/tex].

I think its a homogeneous mixture (pls correct me if im wrong)

Explanation:

It is a homogeneous mixture because its an alloy made of gold, silver, copper, and other metals that are melted together. A homogeneous mixture is composed of a uniform composition of particles.

There are two types of mixture, one is homogeneous mixture and other is heterogeneous mixture. Therefore, the term best describes 10-karat gold is homogeneous mixture.

When two or more compounds are combined but each ingredient retains its chemical identity, the result is referred to as a mixture. In other words, there is no chemical interaction between the parts of a combination. According to how consistent they are and how well the components' particle sizes match up, mixtures are categorized.

Because it is an alloy comprised of melted gold, silver, copper, and other metals, it is a homogenous combination. A homogeneous mixture has a consistent distribution of its constituent particles.

Therefore, the term best describes 10-karat gold is homogeneous mixture.

Using the Rydberg formula, the spectral line of H - atom is suitable for this purpose is Paschen, ∞ → 3.

1/λ = RH(1/nf^2 - 1/ni^2)

Given that;

λ = wavelength

RH = Rydberg constant

nf = final state

ni = initial state

Then;

1/λ =  1 × 10^7 m-1 (1/3^2 - 1/ ∞^2)

1/λ =  1 × 10^7 m-1 (1/3^2 )

λ = 900 nm
