The answer is A) Water has surface tension.
This is the correct answer because water allows animals and really light items to rest upon the top of the water.
Hope This Helps! If you could mark me as the brainiest answer, that would be amazing. I want others to read this answer and know it is accurate. If you need help with another question, just ask. :)
Answer:
The correct order of increasing vapor pressure: Z,Y,X
Explanation:
It is given that the normal boiling point order of three liquids is:
Normal Boiling point is defined as the temperature at which the vapor pressure becomes equal to the atmospheric pressure.
Vapor pressure is the pressure exerted by vapor on the surface of liquid.Hence it increases with tendency of vapor formation.
High boiling point implies that high energy is required to convert the liquid into vapor state and hence the vapor pressure reaches atmospheric pressure at higher temperatures.
Low boiling point implies that the liquid gets easily boiled at a low temperature and converts into vapor with ease and hence exert high vapor pressure.
Bottom line is vapor pressure decreases as boiling point increases at STP.
Hence the order of increasing vapor pressure is Z,Y,X
Answer:
I think the answer is 149.4
Nearly 33% of the Earth's land is covered in Arid climate. The word arid means dry. The two colors on the map represent warm and cold Arid climates. If land has an Arid climate it is usually a desert. Most deserts are found along the 30 degree latitude line (north and south of the equator). This is due to the pattern of cold water currents, which force dry air over the land. Other Arid climates exist in the center of continents or in the rain shadow of large mountain ranges. A rain shadow is land on a side of a mountain that is very dry because the mountain forces warm air higher into the sky, which cools it and it falls as rain, but only on one side of the mountain. Most Arid areas do not have regular seasons. For instance, the Sahara Desert is always hot and dry. However, some places do have changes in temperature depending on the latitude and the surrounding climates. So, since there are temperature differences, we can say there are 2 seasons, summer and winter. Hope this helps! ~ Autumn :)
Answer:
(a) When aqueous solution of hydrochloric and ammonia chemically react together then it results in the formation of ammonium chloride.
The reaction equation for this reaction is as follows.
Now, ioni equation for this reaction is as follows.
Cancelling the spectator ions, the net ionic reaction equation is as follows.
(b) When sodium hydroxide chemically reacts with ammonium chloride then it forms ammonia, water and sodium chloride as follows.
Now, the total ionic equation will be as follows.
Cancelling the spectator ions from the above equation. Then the net ionic equation will be as follows.
