178.87 grams of sulphur dioxide is formed according to the equation given.
Explanation:
The balanced chemical reaction for the process is:
4 FeS2 + 11 O2 ⇒ 2Fe2O3(-) + 8 SO2
the reaction involving FeS and oxygen having balanced chemical equation as:
moles of oxygen given as 3.84
so when 11 moles of O2 reacts to form 8 moles SO2
3.84 moles of oxygen reacts to form x moles of SO2
= 
x = 
2.792 moles of sulphur dioxide will be formed
The mass can be calculated as number of moles x molar mass of 1 mole of SO2
= 2.792 x 64.066
= 178.87 grams of sulphur dioxide is formed.
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.

<h3><u>Answer</u>;</h3>
pH = 4.38
<h3><u>Explanation;</u></h3>
Consider that ;
[H3O+] = 10-pH mol/L
Therefore; the pH is the -log of the [hydronium ion].
pH = - log [H3O+]
Thus;
pH = - log (4.2 × 10^–5)
= 4.38
Answer:
1 is c 2 is b
Explanation:
because atomic number is the number of protons in a nucleus
2..because the number of protons plus number of neutrons is equal to mass number.
