Answer:

here

Explanation:

FRICTION ADVANTAGES:

a) the soles of are shoes are designed in a way that they create friction and prevent us from slipping and falling.

b) We are capable of writing with a pen due to the friction between the pen and the paper.

FRICTION DISADVANTAGES:

b) Forest fires are caused due to the friction between the trees branches

Classify the compound below as an alkane, alkene, alkyne, alcohol, aldehyde, amine, and so forth
Gnoma [55]

<em>Answer:</em>

  • Organic compounds are those which are derivatives of hydrocarbons. They are classified into following functional groups.

<em>Alkane:  </em>

  • Alkane are simplest hydrocarbons.
  • They have general formula CnH2n+2. These hydrocarbons contain single bond.
  • For example ethane , H3C----CH3.

<em>Alkene:</em>

  • Alkene are most reactive.
  • They have general formula CnH2n.
  • These contain double bond in their structure.
  • For example , ethene, H2C=CH2

<em>Alkyne:</em>

  • These are less less reactive as compare to alkenes.
  • They have general formula CnH2n-2.
  • They contain triple bonds in their structure.
  • For example Acetylene HC≡CH

<em>Alcohol:</em>

Alcohol have functional group OH. They have general formual R---OH, R may be alkyl group.For example Ethanol H3CH2C---OH

<em>Amine:</em>

  • Amine contain NH2 F.G.
  • They have general formula R---NH2.
  • There are three types of amine like primary, secondary and tertiary amine.
  • For example H3CH2C---NH2

<em>Aldehyde:</em>

  • Aldehydes have CHO F.G .
  • They have general formula R--CHO.
  • For example H3CH2C---CHO

<em>Ketone:</em>

  • Ketones have R--CO--R functional group.
  • For example acetone H3C---CO---CH3

<em>Carboxylic acid:</em>

  • They functional group COOH.
  • Their general formula is R---COOH.
  • For example Acetic acid H3C---COOH

What is closest packing? What is the difference between hexagonal closest packing and cubic closest packing? What is the unit ce
Paladinen [302]

Answer:

In crystal structure close packing is define as space efficient arrangement of constituent particles to form a crystal lattice.

Explanation:

closest packing

In crystal structure close packing is define as space efficient arrangement of constituent particles to form a crystal lattice.

Difference between hexagonal closest packing and cubic closest packing

In cubic closest packing arrangement, each sphere is surrounded by 12 other spheres on the other hand in case of hexagonal close packing, layers of spheres are packed so that spheres in alternating layers overlie one another.

unit cell for each closest packing arrangement

The hexagonal closest packed arrangement has a coordination number of 12 and it consists of 6 atoms per unit cell. The face centered cubic lattice has a coordination number of 12 and it consists of 4 atoms per unit cell. In case of body centered cubic crystal the coordination number is 8 and it consists of 2 atoms per unit cell.

How many grams of water can be produced in the combination of
mel-nik [20]

If 14 grams of hydrogen reacted with 24.7 grams of oxygen 27.7875 grams of water will be formed.

Explanation:

2H2+O2----------->2H2O.

  • From the above equation, we can say that 4g of Hydrogen will react with 32 g of oxygen.
  • In this question, Hydrogen is in excess amount.
  • 32 g of Oxygen will react with = 4 g of H2.
  • Therefore 24.7g of Oxygen will react with =24.7x4/32= 3.0875 g H2.  
  • The remaining 10.9125g of H2 will be left unreacted.
  • Therefore the amount of water formed=(24.7+3.0875)=27.7875 g

Cerebrospinal fluid of the central nervous system and synovial fluid of joint capsules are both examples of _______.
murzikaleks [220]

Cerebrospinal fluid of the central nervous system and synovial fluid of joint capsules are both examples of <u>extracellular </u><u>fluid</u>

  • Extracellular fluid called cerebrospinal fluid is present throughout the CNS
  • It acts as a protective layer for CNS ftom injury and shock
  • Cerebrospinal fluid is clear, colorless fluid produced by the choroid plexus.
  • It surrounds the brain and spinal cord.

Synovial fluid is a viscous solution found in cavities of synovial joints. The principal role of synovial fluid is to reduce friction between articular cartilages of synovial joints during movement.

  • Synovial fluid is a small component of transcellular fluid component of extracellular fluid.
