Answer:

The female are represented as XX, XX, XX.

The male are represented as XY, XY, XY

Explanation:

Th female sex chromosome is represented as XX.

The male sex chromosome is represented as XY.

From the question given above, there are three female and three male.

The female are represented as XX, XX, XX.

The male are represented as XY, XY, XY

Balance the following chemical equation
ratelena [41]

Answer:

Explanation:

4). Ca(NO₃)₂ + Na₂SO₄ → CaSO₄ + 2Na(NO₃)₂

  This question is incorrect.

  Since, the final product by reacting Na⁺⁺ and NO₃⁻⁻ is NaNO₃

  Correct equation will be,

  Ca(NO₃)₂ + Na₂SO₄ → CaSO₄ + 2NaNO₃

  This equation is in the balanced form.

5). Ni(NO₃)₂ + KI → NiI + 2K(NO₃)₂

  Correct equation will be,

  Ni(NO₃)₂ + KI → NiI₂ + 2KNO₃

  [Since final product by reacting Ni⁺⁺ and I⁻ is NiI₂]

  Balanced form of this equation will be,

  Ni(NO₃)₂ + 2KI → NiI₂ + 2KNO₃

6). Ni(NO₃)₂ + KOH → NiOH + K(NO₃)₂

   Correct form of the equation will be

   Ni(NO₃)₂ + KOH → Ni(OH)₂ + KNO₃

   [Since reaction of Ni⁺⁺ and OH⁻ gives Ni(OH)₂ and the reaction of K⁺ and NO₃⁻ gives KNO₃]

   Now balancing this equation,

   Ni(NO₃)₂ + KOH → Ni(OH)₂ + 2KNO₃

                              ↓

  Ni(NO₃)₂ + 2KOH → Ni(OH)₂ + 2KNO₃

Classify the reactions as endothermic or exothermic....PLEASE HELP ASAP
elena55 [62]

1) Endothermic reactions:

a) The reaction between ammonium nitrate and water absorbs heat from the surrounding environment.

There are two types of reaction: endothermic reaction (chemical reaction that absorbs more energy than it releases) and exothermic reaction (chemical reaction that releases more energy than it absorbs).

b) Ammonium chloride dissolved in a beaker of water makes the beaker cold.

Dissolving this salt absorbs heat from beaker.

c) Water separates on hydrogen and oxygen when an electric current is run through it.

Electrolysis of water is the decomposition reaction (heat is required), because from one molecule (water) two molecules (hydrogen and oxygen) are produced. Water is separated into two molecules.

2) Exothermic reactions:

a) Three drops of concetrated sulfuric acid added to 100 milliliters in a beaker makes the beaker hot.

Energy is released, beaker absorbs that heat.

b) Uranium atoms are split to produce nuclear energy.

Nuclear energy is released.

c) Methane and oxygen are combined to produce methanol and heat.

Balanced chemical reaction: 2CH₄ + O₂ → 2CH₃OH + heat.
