(1) an effective collision between reacting particles

Explanation:

In order for a chemical reaction to occur, an effective collision between reacting particles must always be.

  • Based on the collision theory, for reactions to occur, there must be collisions between the reacting particles.
  • It implies that the rate of reaction depends on the number of collision per unit time as well as the fraction of this collision that is successful or effective.
  • For collisions to be effective, they must have adequate energy.

C.Convert the following using the molar mass of each:
Alik [6]

Answer:

1. 1.145 mole

2. 19.368g

3. 66.67 moles

4. 0.0056g

Explanation:

The following calculations gives the answers to the various questions asked above:

1. Molar mass of NaCl = 23 + 35.5 = 58.5g/mol

Mass of NaCl from the question = 67g

Number of mole NaCl =.?

Number of mole = Mass /Molar Mass

Number of mole NaCl = 67/58.5

Number of mole of NaCl = 1.145 mol

2. Number of mole of H2O = 1.076 mole

Molar Mass of H2O = (2x1) + 16 = 2 + 16 = 18g/mol

Mass of H2O =?

Mass = number of mole x molar Mass

Mass of H2O = 1.076 x 18

Mass of H2O = 19.368g

3. Molar mass of C6H12O6 = (12x6) + (12x1) + (16x6) = 72 + 12 + 96 = 180g/mol

Mass of C6H12O6 = 1.2x104g

Mole of C6H12O6 =.?

Number of mole = Mass /Molar Mass

Mole of C6H12O6 = 1.2x104/180

Mole of C6H12O6 = 66.67 moles

4. Molar mass of Br2 = 2 x 80 = 160g/mol

Mole of Br2 = 3.5x10^-5 moles

Mass of Br2 =?

Mass = number of mole x molar Mass

Mass of Br2 = 3.5x10^-5 x 160

Mass of Br2 = 5.6x10^-3 = 0.0056g

How are monosaccharides and polysaccharides structurally different? *NO PLAGIARISM PLS*
Mariana [72]

Explanation:

Monosaccharides are simple carbohydrates that cannot be further hydrolyzed to simpler carbohydrates. They contain between three and six carbon atoms per molecule.

Polysaccharides  are complex carbohydrates . They are condensation polymers derived from very long chains of monosaccharide units.

Structurally, polysaccharides are made up of repeating units of monosaccharides.
