Answer:

A few Scientists believe it is correct

Explanation:

A hypothesis is the first step in the scientific method.

It is a basis to start a scientific work, and a suggestion for unexplained theories and scientists put it forward on the basis of their some observations

So it first a scientist put a hypothesis forward and the work for it in details to prove his/her hypothesis.

That’s why few scientists believe it is correct as they work on it to give proof for it correct. But other scientist needs results.

A. In the complete reaction of 22.99 g of sodium

fenix001 [56]

Answer : 58.44 g

<h3>Further explanation</h3>

The reaction

$\tt Na+Cl\Rightarrow NaCl$

mole ratio :

Na : Cl : NaCl = 1 : 1 : 1

Molar mass of Na : 22,989769 g/mol = 22.99 g/mol

Molar mass of Cl : 35,453 g/mol= 35.45 g/mol

Molar mass of NaCl : 58,44 g/mol

Let's check the mol for reactant (Na and Cl) and product(NaCl)

mol of Na :

$\tt mol=\dfrac{22.99}{22.99}=1$

mol of Cl :

$\tt mol=\dfrac{35.45}{35.45}=1$

Then the reactants are completed reacting because it matches the mole ratio, which is 1: 1

so that the mole of the product can be determined from the mol Na or Cl, which is 1

mass of NaCl :

$\tt =\dfrac{mol~NaCl}{mol~Na}\times MW~NaCl\\\\=\dfrac{1}{1}\times 58.44\\\\=\boxed{\bold{58.44~g}}$

Coal can be converted to methane gas by a process called coal gasification. The equation for the reaction is the following: 2 C

zloy xaker [14]

Answer:

24 g of C are needed to produce 1mol of CH₄

Explanation:

The reaction is:

2C (s) + 2H2O (l) → CH4(g) + CO2 (g)

2 moles of carbon react with 2 moles of water in order to produce 1 mol of methane and 1 mol of carbon dioxide.

If we want to produce 1 mol of methane, we need 2 moles of C

Let's find out the mass → 2 mol . 12 g/1 mol = 24g
