A pair of elements will most likely form an ionic bond if one is a metal and one is a nonmetal. These types of ionic compounds are composed of monatomic cations and anions.
6. Why can't water be used to dissolve the
caffeine found in coffee and tea?
Alcohol is used to extract caffeine
Tea's chief component is cellulose, which is not soluble in water. Caffeine is water soluble, but so are tannins and gallic acid, which have been established during the heating process of tea leaves. The latter two components can be converted to insoluble in water calcium salts.
What is solubility?The maximum amount of a substance that will dissolve in a given amount of solvent at a given temperature is defined as solubility.
Solubility is a property of a specific solute-solvent combination, and the solubilities of different substances vary greatly.
It is one of the critical parameters for achieving the desired drug concentration in systemic circulation for the desired (anticipated) pharmacological response.
Caffeine is more soluble in nonpolar methylene chloride than in water, so it will migrate to the methylene chloride layer (known as the organic layer). Because the organic layer is denser than water, it will be at the bottom.
Thus, water can not be used to dissolve the caffeine found in coffee and tea.

Write the number of each atom in the chemical formulas for all of the possible combinations of positive and negative ions found on the cards. You can use the cards to figure out the formula by making as many copies of the cards as necessary to get them to line up exactly equally.
Example:
Na__Cl___
The chemical formula is NaCl, so you would place a 1 in the box for both Na and Cl.
A chemical formula is obtained from the number of atoms in a compound.
Chemical compounds are composed of atoms. The number atoms of each element in a compound determines the correct formula of the compound. Before I can write the chemical formula of any compound, I must first determine the number of each atom in the compound.
For instance, phosphorus trichloride contains one atom of phosphorus and three atoms of chlorine hence I would place a 1 in the box for P and 3 in the box for Cl.

Answer:
A.
Explanation:
Liquid particles are close enough but not too tightly packed like solids.
Solid particles are tightly packed so that they can't move.
Gas particles move randomly.
They constantly collide with each other. This type of motion is called Brownian Movement.

State the role of the light stage of photosynthesis to the Calvin cycle.
Answer:
In the light-independent reactions or Calvin cycle, the energized electrons from the light-dependent reactions provide the energy to form carbohydrates from carbon dioxide molecules. The light-independent reactions are sometimes called the Calvin cycle because of the cyclical nature of the process.

What term is used to describe the state at which a solute moves down its concentration gradient
through the plasma membrane and becomes evenly distributed in the cytosol?
Diffusion is used to describe the condition at which a solute moves down its concentration gradient through the plasma membrane and becomes uniformly distributed in the cytosol.
What is Diffusion?Diffusion is the type of net movement of particles from an area of higher concentration to an area of lower concentration. It is driven by the gradient in Gibbs free energy or chemical potential.
This occurs through the semi-permeable membrane like the plasma membrane. Diffusion of small molecules and macromolecules such as proteins in aqueous solutions plays an important role in microorganisms, plants and animals.
Few examples of Diffusion are:
Perfume is sprayed in one part of the room so that it can spread easily so that we can feel its smell everywhere. A drop of food coloring spread throughout the water in a glass, the whole glass will be colored.Thus, Diffusion is used to describe the condition at which a solute moves down its concentration gradient through the plasma membrane and becomes uniformly distributed in the cytosol.

Black fur (B) is dominant to white fur. Soft fur (S) is dominant to rough fur. What is probability that the
offspring will have white color and rough fur?
Answer:
A) 1/16
Explanation:
Because both white fur and rough fur are recessive traits, you need all genes shown to also be recessive. If a single trait is dominant, then it will be expressed instead of a recessive gene. Because there is only one square out of sixteen that is all lowercase, the chance of having both recessive traits (White fur and Rough fur) is 1/16.
