Chemistry
1 answer:
QveST [7]3 years ago
6 0
Camouflage, mimicry, and animals' body parts and coverings are physical adaptations. The way in which an animal behaves is an adaptation, too—a behavioral adaptation . Behaviors that animals are born knowing how to do are instincts . A lion preying upon a zebra and a bird building a nest are examples of instincts.

Calculate the heat change involved when 2.00 L of water is heated from 20.0/C to 99.7/C in
Pani-rosa [81]

Answer:

666,480 Joules or 669.48 kJ

Explanation:

We are given;

  • Volume of water as 2.0L or 2000 ml

but, density of water is 1 g/ml

  • Therefore, mass of water is 2000 g
  • Initial temperature as 20 °C
  • Final temperature as 99.7° C

Required to determine the heat change

We know that ;

Heat change = Mass × Temperature change × specific heat

In this case;

Specific heat of water is 4.2 J/g°C

Temperature change is 79.7 °C

Therefore;

Heat change = 2000 g × 79.7 °C × 4.2 J/g°C

                      = 669,480 Joules 0r 669.48 kJ

Thus, the heat change involved is 666,480 Joules or 669.48 kJ

How do you write out and balance calcium hydroxide reacts with hydrogen chloride to produce calcium chloride and water
Temka [501]

Answer:

 Ca(OH)₂ + 2HCl →  CaCl₂ +  2H₂O

Explanation:

Reactants;

     Calcium hydroxide = Ca(OH)₂

     Hydrogen chloride  = HCl

 Products;

       Calcium chloride  = CaCl₂

        Water  = H₂O

The reaction equation:

           Ca(OH)₂ + 2HCl →  CaCl₂ +  2H₂O

The reaction is a neutralization reaction where acids reacts with bases to produce salt and water only.
