Answer:
In a steam engine into a reciprocating piston cylinder assembly a high pressure steam is been admitted.
Explanation:
Steam engine: High-pressure steam is been injected into a piston-cylinder assembly which is reciprocating in nature. some part of its thermal energy gets converted into movement of the piston to work,When the steam starts expanding to lower pressure.
Apparatus which is separate and a condenser at comparatively low temperature and pressure here steam is passed.The expanded steam can then be made to be free, or, for engine efficiency to be maximum, Rotary motion with a crank-crankshaft assembly similar to that used in automobiles gets transferred from that.
Remaining heat has been now used for warming water.
boiler fired with coal, oil, or natural gas by them the steam gets supplied.
. In many areas, more reliable and economical diesel-electric locomotives gets supplanted by the steam locomotives.
The steam engines today generally are regarded as a unique piece as they are not considered as above reasons are explained.
Nevertheless, the creation of the steam engine played a vital role in the Revolution carried out by the industries by creating a society which now is less dependent on the different windmills, the watermills and mostly the animal power.
Answer:
HCO₂
Explanation:
From the information given:
The mass of the elements are:
Carbon C = 26.7 g; Hydrogen H = 2.24 g Oxygen O = 71.1 g
To determine the empirical formula;
First thing is to find the numbers of moles of each atom.
For Carbon:
For Hydrogen:
For Oxygen:
Now; we use the smallest no of moles to divide the respective moles from above.
For carbon:
For Hydrogen:
For Oxygen:
Thus, the empirical formula is HCO₂
Answer:
Pollution, non native species being introduced, and other human activities
Explanation:
Human activities affect marine ecosystems as a result of pollution, overfishing, the introduction of invasive species,and acidification, which all impact on the marine food web and may lead to largely unknown consequences for the biodiversity and survival of marine life forms.
