Answer:
8 mol of hydrogen will react with 1 mol of sulfur.
Explanation:
We'll begin by writing the balanced equation for the reaction.
This is given below:
8H2 + S8 —> 8H2S
Now, let us carefully observe the mole ratio of the reactants.
This is illustrated:
The mole ratio of the reactants ( i.e H2 and S8) is 8 : 1
From the balanced equation above,
We can thus, concluded that:
8 moles of H2 will reacted with 1 mole of S8.
<h3>Answer:</h3>
Number of Protons = 6
Number of Electrons = 6
Number of Neutrons = 7
<h3>Explanation:</h3>
Number of Protons:
As the number of protons present in the nucleus are equal to the atomic number therefore, using periodic table one can easily find out the atomic number of C atom. Hence, C is present in group 14 and period 2 and having an atomic number of 6. Therefore, number of protons in C atom are 6.
Number of Electrons:
As shown in statement, C is not carrying any type of charge. It means this atom is neutral in nature. Which means, it is carrying the same number of electrons as the number of protons in order to give a neutral atom. Therefore, it contains 6 electrons.
Number of Neutrons:
Number of neutrons can be calculated using following formula,
No. of Neutrons = Atomic Mass - Number of Protons
As,
Atomic Mass = 13
So,
No. of Neutrons = 13 - 6
No. of Neutrons = 7
Answer:
Compound.
Explanation:
That would be compound as it consists of a number of elements bonded together. It is inorganic not organic.
Answer:
C. Ca.
Explanation:
The atom loses or gains electrons forming anion or cation to reach stability (fill the outermost shell of the electron levels).
When atom gains electrons forms anions with negative charge.
While, when atom loses electrons forms cations with positive charge.
A. O:
O atom has 8 electrons in its nucleus and gains 2 electrons to reach stability (10 electrons, configuration of Ne).
<em>So, it forms O²⁻.</em>
<em></em>
B. AI:
Al atom has 13 electrons in its nucleus and loses 3 electrons to reach stability (10 electrons, configuration of Ne).
<em>So, it forms Al³⁺.</em>
<em></em>
C. Ca:
Ca atom has 12 electrons in its nucleus and loses 2 electrons to reach stability (10 electrons, configuration of Ne).
<em>So, it forms Ca²⁺.</em>
<em></em>
D. Na:
Na atom has 11 electrons in its nucleus and loses 1 electron to reach stability (10 electrons, configuration of Ne).
<em>So, it forms Na⁺.</em>

A. Compound that has the highest solubility in pure water is caso4, ksp = 2. 4 x 10-5
More about CASO4:
The inorganic chemical with the formula CaSO4 and its associated hydrates are known as calcium sulphate (sometimes known as calcium sulphate). It serves as a desiccant in the form of -anhydrite (the anhydrous form).
Another hydrate is found naturally as the mineral gypsum, while one is more commonly known as plaster of Paris. It is employed widely in industries. Each form is a white solid that has a low water solubility. Water becomes permanently hard due to calcium sulphate.
CaSo4 is mostly used to produce plaster of Paris and stucco.
