How much sulfur (in tons), present in the original materials, would result in that quantity of S)2

1 answer:

3 0

Sulfur reacts with oxygen to produce sulfur dioxide. That is for every mole of sulfur reacted, one mole of sulfur dioxide also is produced. With the given mole of sulfur dioxide, the amount of sulfur in mass is determined by multiplying the number of moles to the molar mass of sulfur (32 g/mol).

Ammonia is produced commercially by the Haber reaction: N2(8)+ 3H2(8)

Shalnov [3]

This is an incomplete question, here is a complete question.

Ammonia is produced commercially by the Haber reaction:

$N_2(g)+3H_2(g)\rightarrow 2NH_3(g)+Heat$

The formation of ammonia is favored by

A) an increase in pressure

B) a decrease in pressure

C) removal of N₂(g)

D) removal of H₂(g)

Answer : The correct option is, (A) an increase in pressure.

Explanation :

Any change in the equilibrium is studied on the basis of Le-Chatelier's principle.

Le-Chatelier's principle states that if there is any change in the variables of the reaction, the equilibrium will shift in the direction to minimize the effect.

Increase the pressure :

If the pressure in the equilibrium is increased, the equilibrium will shift in the direction where fewer total molecules are shown in the balanced chemical equation.

In the given reaction, there are 4 molecules present on reactant side and 2 molecules on product side. That means, less molecules present on product side. Thus, the reaction will shift in right direction that is towards the product.

Removal the reactant molecule :

If any of reactant molecule in the equilibrium is removed, then the equilibrium will shift in left direction that is towards the reactant.

Hnece, the formation of ammonia is favored by an increase in pressure.

What would be the best method to separate this solid from the solution?

PolarNik [594]

The best way to separate out a precipitate is using vacuum filtration. Use water to rinse out the flask thoroughly and wash the precipitate, followed by a quick rinse with ethanol to help dry it. After a few minutes on the vacuum pump, the precipitate should be ready to scrape off.<span> Also, centrifugation can be an option for small amounts especially if you just need the filtrate. For reasonable amounts, a Millipore setup or Gooch type crucible works nicely for quantitative analysis.</span>

Combustion of hydrocarbons such as butane () produces carbon dioxide, a "greenhouse gas." Greenhouse gases in the Earth's atmosp

Dahasolnce [82]

Answer:

1. C₄H₁₀ + ¹³/₂O₂ → 4CO₂ + 5H₂O

2. V = 596L

Explanation:

Butane (C₄H₁₀) reacts with oxygen (O₂) to produce carbon dioxide (CO₂) and water (H₂O) thus:

C₄H₁₀ + O₂ → CO₂ + H₂O

1. The balanced chemical equation is:

C₄H₁₀ + ¹³/₂O₂ → 4CO₂ + 5H₂O

2. 0,360kg of butane are:

360g× $\frac{1mol}{58,12g}$ =<em>6,19moles of butane</em>

These moles of butane are:

6,19moles of butane× $\frac{4CO_2}{1molButane}$ = <em>24,8 moles CO₂</em>

Using V=nRT/P

Where:

n are moles (24,8 moles CO₂); R is gas constant (0,082atmL/molK); T is temperature, 20°C (293,15K); and P is pressure (1atm).

Volume (V) is:

Can I get some help please I’m lost :(

Molodets [167]

Answer:

C) 11 g

Explanation:

first look to graph , you have x and y

x is mass of Fe

and y is mass of product

if the reaction consumes 2 g of Fe , ( look to x axis , look to 2 )

and go up until the black line touch the line of number 2

and go left and you will see the point become in the middle between 10 and 12

** 12 (11) 10 ***

Good Luck

A temperature regime that experiences consistent high temperatures with little seasonality is the?

cupoosta [38]

A temperature regime that experiences consistent high temperatures with little seasonality is the <u>equatorial</u>.

<h3>What is temperature regime?</h3>

These systems have a significant impact on how soils are used and managed, especially when choosing plants that are adapted to the environment. There are 10 different soil temperature regimes: cryic, frigid, hyperthermic, isofrigid, isohyperthermic, isomesic, isothermic, mesic, pergelic, and thermic.

<h3>What is a mesic temperature regime?</h3>

Mesic. At a depth of 50 cm from the soil surface or at a dense, lithic, or paralytic contact, whichever is shallower, the difference between the mean summer and mean winter soil temperatures is greater than 6° C and the mean annual soil temperature is 8° C or higher but lower than 15° C.
