Answer:
i) The reactants are sodium sulphate and barium chloride
ii) The products are barium sulphate and sodium chloride.
Explanation:
In chemistry, a chemical reaction occurs when one or more chemical substances usually referred to as REACTANTS undergoes some processes and is converted to one or more different substances known as PRODUCTS.
From the question:
Na2SO4 + BaCl2 ⟶ 2NaCl + BaSO4
The above balanced equation represents the chemical reaction between sodium sulphate and barium chloride. Both are the reactants because they where the substances that passed through a process ( this involves the breaking of bond that held them together).
The PRODUCTS are barium sulphate and sodium chloride because they are the substances that presented at the end of the chemical reaction.
Answer:
The two components are biotic and abiotic components
Explanation:
The two components essential for the functioning of the ecosystem are:
Biotic Components:
These are the organic components like plants, pathogens, animals, human beings and other living components in the ecosystem that affects other living organisms, influences them and helps in shaping the ecosystem.
they require desired amount of nutrition and energy and energy for proper everyday functioning.
They are further classified as Producers, decomposers and consumers out of which producers prepare their own food by photosynthesis where consumers fulfills their requirement from producers and decomposers depend s on both producers and consumers for chemical breakdown into simpler and reusable forms.
Abiotic Components:
These are the inorganic components of the ecosystem like humidity, temperature, etc.
These are the non living components of the ecosystem which includes physical and chemical constituents of the environment which influences the biotic components and the ecosystem's functioning.
The abiotic components influences certain behaviors in living organisms like reproduction, growth, etc.
These components are synthesized by the process of photosynthesis by utilizing sunlight to convert these into organic compounds by primary producers which are further are the consumption of secondary producers thus increasing the organic content.
One should never anchor in a narrow channel, until unless required very importantly. One should stay to the starboard side, and use a prolonged blast. The announcement must be done to alarm the nearby vessels, about your approach. The vessel should be kept at the outer limit of the starboard side.
Answer:
1. The number of turns on the secondary output is 18
2. The root mean square power delivered to the transformer is 48 Watts.
Explanation:
A transformer is an electronic device that can be used for increasing or decreasing the value of a given voltage. It consists of primary coils and secondary coil of a definte number of turns. When voltage flows in the primary coil, it induces voltage in the secondary coil. The two types are: step-up and step down transformers.
1. For a given transformer,
= 
where 
is the value of the induced voltage in the secondary coil, 
is he voltage in the primary coil, and 
is the number of turns of the secondary coil, 
is the number of turns in the primary coil.
From the question,
= 9.0 V, = 120 V, = 240, = ?
So that,
= 
= 
= 18
The number of turns on the secondary output is 18.
2. 
= 
× 
= 0.4 × 120
= 48 W
The rms power delivered to the transformer is 48 Watts.
