Answer:
2 and 1
Explanation:
since oxygen has four atom and water has one molecule of oxygen
since o2 is liberated then 2 will be the coefficient in front of water
Answer: Option (C) is the correct answer.
Explanation:
A force is defined as the strength applied on an object to displace it from its initial position.
This, force applied to move the object is known as work.
Mathematically, W = F × d
where W = work done
F = force
d = displacement or distance moved
Thus, we can conclude that the statement forces are defined by both strength and direction, is true about forces.
Answer:
C
Explanation:
The direction and strength affect the force

Explanation:
The particles that make up soil are categorized into three groups by size: sand, silt, and clay. Sand particles are the largest and clay particles the smallest. Although a soil could be all sand, all clay, or all silt, that's rare. Instead most soils are a combination of the three.
The relative percentages of sand, silt, and clay are what give soil its texture. A loamy texture soil, for example, has nearly equal parts of sand, silt, and clay.
SOIL HAS STRUCTURE
Soil structure is the arrangement of soil particles into small clumps, called "peds". Much like the ingredients in cake batter bind together to form a cake, soil particles (sand, silt, clay, and organic matter) bind together to form peds. Peds have various shapes depending on their “ingredients” and the conditions under which the peds formed: getting wet and drying out, freezing and thawing--even people walking on or farming the soil affects the shapes of peds.
Ped shapes roughly resemble balls, blocks, columns, and plates. Between the peds are spaces, or pores, in which air, water, and organisms move. The sizes of the pores and their shapes vary from soil structure to soil structure.

We can expect to find carbon in all living organisms and in all organiccompounds. So the correct options are A and C.
Carbon is an element found on the earth. It is an extremely abundant element with unique properties. Carbon is present in the environment in pure or almost pure forms.
Diamonds and graphite are some of the pure forms of carbon. Carbon also forms compounds with other elements for the formation of molecules.
These carbon-based molecules are the basic building blocks of all living organisms including humans, animals, plants microorganisms etc.
These also present many components of the environment. They are called organic molecules. Greenhousegases like carbon dioxide and methane are examples of carbon-based molecules.
They are also present in high percentages of fossilfuels. They are mainly made up of hydrocarbons which are molecules composed of hydrogen and carbon.
Therefore the correct options are A and C.
