The three components are:

  1. Minerals.
  2. Organic matter.
  3. Living organisms.

Explanation:

Soil is made up of three main components:

  1. Minerals that come from rocks below different layers of the soil.
  2. Organic matter(humus) which is the remains of plants and animals that increases the fertility of the soil and also increases the water holding capacity of soil.
  3. Living organisms that reside in the soil.

Result: The three main components of soil are minerals, organic matter, living organisms.

245 g water sample initially at at 32 oC absorbs 17 kcal of heat. What is the final temperature of water?
steposvetlana [31]

Answer:62.66°C or 235.66K

Explanation:Q=McpT, the energy was given in calories so you first convert to Joules by multiplying the value in calories by 4.184J.

17*4.184=71.128kJ.

71.128kJ=mcpT

71.128kJ=245*4.187*(T-Tm)

Tm is the final temperature of the mixture. The T is the temperature given which should be converted to Kelvin by adding 273...T=32+273=305K.

71128J=245*4.187*(305-Tm)

71128=312873.575-1025.815Tm

1025.815Tm=312873.575-71128

1025.815Tm=241745.58

Tm=241745.58/1025.815

Tm=235.66K

The electronic configuration of an element is given below.
Amiraneli [1.4K]

 The statement  which  is true  about  the reactivity  of  element  with          1S²2S²2P⁶3S¹   is

 it is reactive   because it has to lose one  electron  to have  a full  outermost  energy  level.

<u><em>Explanation</em></u>

  • <u><em> </em></u>Element  with     1S²2S²2P⁶3S¹  electron configuration  is    a sodium  metal.
  •    sodium  has  one  electron  in the outermost energy level.
  • for  sodium to have  a full  outermost  energy level (  8 electrons) it   loses  the  1  electron   in 3S¹ to  form   a positively  charged ion. (Na⁺)
