Answer:

An F1 offspring could produce four types of gametes, RY, Ry, rY, and ry. The F2 generation supports the independent-assortment model and refutes the linkage model.

How many moles of ions are released when 0.27 mole of cobalt chloride is dissolved in water?

egoroff_w [7]

0.81 moles

Explanation:

cobalt chloride when dissolved in water dissociate into cobalt and chloride ions as shown;

CoCl₂ (s) → [Co²⁺](aq) + 2[Cl⁻] (aq)

The mole ratio between CoCl₂ and [Co²⁺] is 1 ; 1 while the mole ratio between CoCl₂ and [Cl⁻] is 1 : 2

Therefore; 0.27 moles of CoCl₂ will form;

(1 * 0.27) = 0.27 moles of [Co²⁺] ions

(2 * 0.27) = 0.54 moles of [Cl⁻] ions

Total moles of dissociated ions are;

0.27 + 0.54

= 0.81 moles

Using the following equation how many grams of pure oxygen do you need to comsume 635.2g of glucose: C6H12O6 + 6O2 → 6CO2 + 6H2O

aalyn [17]

Answer:

677.76 g of oxygen needed.

Explanation:

Given data:

Mass of glucose = 635.2 g

Mass of oxygen needed = ?

Solution:

Chemical equation:

C₆H₁₂O₆ + 6O₂ → 6CO₂ + 6H₂O + energy

Number of moles of glucose:

Number of moles = mass/ molar mass

Number of moles = 635.2 g / 180.156 g/mol

Number of moles = 3.53 mol

Now we will compare the moles of glucose with oxygen.

C₆H₁₂O₆ : O₂

1 : 6

3.53 : 6×3.53 = 21.18 mol

Mass of oxygen:

Mass = number of moles × molar mass

Mass = 21.18 g × 32 g/mol

Mass = 677.76 g

Give all possible, accurate, correct IUPAC names for the following compounds:

Viefleur [7K]

Answer:

A. 4-ethyl-hex-3,5-dien-2-ol.

B. 2-chloro-3-methyl-5-tert-butylphenol.

Explanation:

Hello there!

In this case, according to the given problems, it is possible to apply the IUPAC rules to obtain the following names:

A. 4-ethyl-hex-3,5-dien-2-ol because we have an ethyl radical at the fourth carbon and the beginning of the parent chain is on the Me (CH3) because it is closest to first OH.

B. 2-chloro-3-methyl-5-tert-butylphenol: because we start at the alcohol and have a chlorine atom on the second carbon, a methyl radical on the third carbon, a tert-butyl on the fifth carbon and the parent chain is benzene which is phenol as an alcohol.

Regards!

Which one of the following reactions IS NOT balanced? 1. 2 KNO3 + 10 K → 5 K2O + N2 2. 2 SO2 + O2 → 2 SO3 3. SF4 + 3 H2O → H2SO3

Delicious77 [7]

Answer:

2 KNO₃ + 10 K → 5 K₂O + N₂ (option 1)

Explanation:

1. 2 KNO₃ + 10 K → 5 K₂O + N₂

We have in reactant side:

2 K, 2N, 6O and 10 K. In conclussion, 12 K, 2N and 6 O

We have in product side.

10 K, 5O and 2 N

This equation is unbalanced

2. 2 SO₂ + O₂ → 2 SO₃

In reactant side we have 2 S and 6 O

In product side we have 2 S and 6 O

3. SF₄ + 3 H₂O → H₂SO₃ + 4 HF

In reactant side we have 1 S, 4F, 6 H and 3 O

In product side we have 1 S, 4F, 6 H and 3 O
