Answer:

B. scientific theory

Explanation:

The scientific theory explains the phenomenon observed in the natural world. It is based upon the scientific method. To arrive at the scientific theory a hypothesis is formed, experiments are designed and conducted, resulted evaluated, analyzed and conclusions are reached. scientific theory are based upon experiments that are tested under controlled conditions.

how is substitution reaction in alkanes different from dehydrogenation reaction since both involve removing a hydrogen atom from
Ilia_Sergeevich [38]

Answer:

See Explanation

Explanation:

A substitution reaction means the replacement of one or more hydrogen atoms in an alkane by another atom or group. It does not introduce a double bond into the product. The product retains single bonds between the species present.

For instance;

CH4 + Cl2 -------> CH3Cl +HCl

is a substitution reaction

Dehydrogenation is the process of removing two hydrogen atoms from a saturated compound compound thereby yielding an unsaturated product.

E.g

C2H6 --------->C2H4 + H2

The key difference is that substitution reaction yields a saturated product while dehydrogenation yields an unsaturated product.

GOOD REWARD<br> I will report those who gives random answers.
Helen [10]

Answer:

3 mol AlCl₃.

Explanation:

Hello!

In this case, according to the specified reactants and products, it is possible to set up the following balanced chemical reaction:

Al(NO_3)_3+3NaCl\rightarrow 3NaNO_3+AlCl_3

Whereas we evidence the 1:3 mole ratio between aluminum nitrate and sodium chloride; thus, since different moles were reacting, we need to identify the limiting reactant by computing the moles of AlCl₃ produced by each reactant as follows:

n_{AlCl_3}^{by\ Al(NO_3)_3}=4molAl(NO_3)_3*\frac{1molAlCl_3}{1molAl(NO_3)_3} =4molAlCl_3\\\\n_{AlCl_3}^{by\ NaCl}=9molNaCl*\frac{1molAlCl_3}{3molNaCl} =3molAlCl_3

Thus, we infer that NaCl is the limiting reactant as it produces the fewest moles of AlCl₃; consequently the produced amount of this product is 3 mol.

Best regards!

Calculate the formula mass of Cuso4​
Mandarinka [93]
Answer: 159.61 g/mol

Copper has a molar mass of 63.546 g/mol

Sulfur has a molar mass of 32.065 g/mol

Oxygen has a molar mass of 16 g/mol, multiply by 4 and it is 16 x 4 = 64 g/mol

63.546 + 32.065 + 64 = 159.61 g/mol
