Answer: Cross breeding

Explanation: Cross breeding can be defined as the method by which two plants can be crossed to produce the desired character and compensate the useless characters shown by the plants individually.

Suppose a plant produces pink flower but small slower and another plant produces white flower but big flower.

If we want big pink colored flower then, these two plants can be crossed among each other so to produce the desired characters and hide the useful characters.

Calculate the density in g/ml of 2.0 L of gasoline that weighs 1.32 kg
sveta [45]

Answer: 0.66 g/mL

Explanation: The formula for density is d= m/v where m=mass and v=volume.

The mass was given in the problem, m= 1.32kg

The volume was also given in the problem, v= 2.0L

d= m/v ---> d= 1.32kg/2.0L ---> d=0.66kg/L

The problem calls for the answer to be written in g/mL, so we must convert the units. 1 kg contains 1000g and 1 L contains 1000 mL.

1000g/1000mL = 1 so the units change but the 0.66 does not. Therefore, your answer is 0.66g/mL (Two significant figures because 2.0 only has 2 significant figures).

Determine if the following compounds are likely to have ionic or covalent bonds. a. Magnesium oxide (MgO) _______________ b. Str
nika2105 [10]

Answer:

The answer to your question is below

Explanation:

Ionic bond is a kind of bond in which a metal attaches to a nonmetal. Also we know that a molecule has ionic bonding if the electronegativity is higher than 1.7.

                    Kind of elements         Difference of electronegativity     Bond

a) MgO         Metal - Nonmetal                3.44 -  1.31 = 2.13                     Ionic

b) SrCl₂        Metal -Nonmetal                  3.16 - 0.95 = 2.21                    Ionic

c) O₃             Nonmetal- Nonmetal          3.44 - 3.44 = 0                      Covalent

d) CH₄O       Nonmetal-Nonmetal           3.44 - 2.55 = 0.89                Covalent

   Carbon, Hydrogen and oxygen are nonmetals

2) Silver coins can conduct electricity.
