Answer:

The answer is <u>Vitamins and minerals</u>

Explanation:

Nutrient molecules maintain/build human cells and tissue, power chemical reactions, and combat disease.

Micro nutrients can be divided into four categories:

  • water-soluble vitamins
  • fat-soluble vitamins
  • macrominerals
  • trace minerals.

Vitamins are organic compound which an organism requires but cannot synthesize by itself in the amount required.

Vitamins are organic compounds made by plants and animals which can be broken down by heat, acid or air. Where as, minerals are inorganic, found in soil or water and cannot be broken down.

Calculate the theoretical yield of alum expected from 0.9875 g of aluminum foil. assume the aluminum is the limiting reactant.
skelet666 [1.2K]

Answer: 17.34 grams of alum will be produced if 0.9875 g of Aluminium foil was used.

Explanation: Reaction to form alum from Aluminium is given as:

2Al(s)+2KOH(aq.)+2H_2O(l)+4H_2SO_4(aq.)\rightarrow 2KAl(SO_4)_2(s).12H_2O(l)+3H_2(g)

We are given Aluminium to be the limiting reactant, so the formation of alum will be dependent on Aluminium because it limits the formation of product.

By stoichiometry,

2 moles of Al is producing 2 moles of Alum

Mass of 2 moles of Aluminium = (2 × 27)g/mol = 54 g/mol

Mass of 2 moles of alum = (2 × 474)g/mol = 948 g/mol

54 g/mol of aluminium will produce 948 g/mol of alum, so

\text{0.9875 grams of aluminium will produce}=\frac{948g/mol}{54g/mol}\times 0.9875g

Amount of Alum produced = 17.34 grams

Theoretical yield of alum = 17.34 grams.

How many HCl molecules and moles are there in 3.65 grams of
ipn [44]

Answer:

0.6022×10²³ molecules

Number of moles = 0.1 mol

Explanation:

Given data:

Mass of HCl = 3.65 g

Number of molecules = ?

Number of moles = ?

Solution:

Number of moles:

Number of moles = mass/molar mass

Number of moles = 3.65 g/36.45 g/mol

Number of moles = 0.1 mol

Number of molecules:

1 mole of any substance contain 6.022×10²³ molecules

0.1 mol ×  6.022×10²³ molecules/ 1 mol

0.6022×10²³ molecules

When a voltaic cell operates, ions move through the(1) anode (2) cathode (3) salt bridge (4) external circuit
forsale [732]
A voltaic cell operates such that the ions move from the negative electrode to the positive electrode.The negative electrode is the cathode while the positive electrode is the anode. This is in reverse to the cation-anion nomenclature. Hence, the answer to this problem is choice 2.
