___________ is the scale used to describe how acidic or basic a solution is. This affects the enzymes within living systems.
nydimaria [60]

Answer:

pH scale

Explanation:

pH scale -

In the field of chemistry , the accurate and exact value of acidity or basicity in a particular solution is calculated with the help of a pH scale .

The scale has reading ranging from 1 to 14 ,

where ,

  • If the pH value less than 7 indicates the solution to be acidic in nature ,
  • If the pH value is exactly equal to 7 , the solution is neutral in nature ,

and ,

  • If the pH value more than 7 indicates the solution to be basic in nature ,

Hence , from the given statement of the question ,

The correct answer is pH scale .

Calculate the molar mass of cacl2
kirza4 [7]

Answer:

\boxed {\boxed {\sf 110.98 \ g/mol}}

Explanation:

The molar mass is the mass of a substance in grams per mole.

To find it, add the mass of each element in the compound. These masses can be found on the Periodic Table.

The compound given is:

CaCl_2

The compound has 1 Ca (calcium) and 2 Cl (chlorine).

 

Mass of Calcium

  • The molar mass of calcium is 40.08 g/mol
  • There is only one atom of Calcium in CaCl₂, so the number above is what we will use.

Mass of Chlorine

  • The molar mass of chlorine is 35.45 g/mol
  • There are two atoms of chlorine in CaCl₂, therefore we need to multiply the molar mass by 2.
  • 35.45 * 2= 70.9 g/mol

Molar Mass of CaCl₂

  • Now, to find the molar mass, add the molar mass of 1 calcium and 2 chlorine.
  • 40.08 g/mol + 70.9 g/mol =110.98 g/mol

The molar mass of CaCl₂ is <u>110.98 grams per mole. </u>

Answer: 2. with two symmetrical shells - mirror images of each other.

the term "crinoid" means: 6. phylum where starfish and sea urchins belong

4. lived inside their shells: 1. exoskeletons are made up of this material

7. multicellular organisms that often live in colonies:  8. individuality of coral is called

Explanation:

Crinoid is a term that can be used to describe the radial symmetry of animals that have oral (side of mouth) and aboral surfaces (opposite to the mouth). It is characterized by the mouth at the top surface and surrounded by the arms for feeding it. This is a characteristic feature of animals like star fish and sea urchins and echinoderm animals.

The exoskeleton is a protective shell which protect the animal from the external environment like water, sunlight and predation.

The multicellular organisms that live in the colonies they form coral reef and individually the are called the coral polyp.
