Organic molecules always contain carbon. They need not always be produced by living organisms and do not necessarily dissolve in water. Moreover, they are not restricted by the composition or ratio of other elements.
The answer to this question pertains to organic molecules. Organic molecules are a type of molecules that always contain carbon. This is represented by option A. This is not restricted by the presence of certain elements or the ratio in which they exist such as hydrogen and oxygen (1:2:1 ratio as mentioned in option B). The notion that organic molecules are produced only by living organisms (option C) is not entirely accurate either. Although they are predominantly found in and produced by living organisms, they can also be synthesized in a laboratory setup. Option D states that organic molecules always dissolve in water, which is not the case, as many organic compounds are
hydrophobic, meaning they repel or fail to mix with water. Therefore, the most accurate statement is A: organic molecules always contain carbon.

Answer:
Autumn is one of the four basic seasons of the year in the temperate climate zone. It is characterized by moderate air temperatures with a decreasing daily average, and relatively high annual precipitation. The climate autumn is the period of the year in which the average daily air temperature ranges around 10° C.
Astronomical fall begins at the fall equinox and lasts until the winter solstice, which roughly means in the southern hemisphere between March 23 and June 22 (sometimes these dates are a day earlier or a day later, and in a leap year they may be additionally retracted one day). During astronomical autumn, the day time of the day is shorter than the night time, and moreover, with each successive day of the day it decreases and night increases.
mass of calcium oxide equals 89.23 g
molar mass of calcium oxide equals 56 G / Mole
the formula which is used as much of CaO equals molar mass of CaO
now put all of the Given values in this formula, we would get the moles of calcium oxide.
moles of CaO= 88.23g over 56g/mole which would get you 1.593 moles
B. 500
C. 50
D. 5
~Hello There!~
Considering that there are 100 cm in a meter, half of that would be 50.
Your answer is C. 50.
Hope This Helps You!
Good Luck :)
Have A Great Day ^_^

Sodium Na is a soft, low-density member of the alkali metal family. The element sodium is a very delicate silvery-white.
Sodium makes up 2.8 percent of the Earth's crust and is the most prevalent alkali metal and sixth most plentiful element on the planet.
A metal is a substance that has a shiny look when freshly processed, polished, or shattered, and conducts electricity and heat rather effectively. Typically, metals are malleable and ductile.
Ionic linkages mix metals with non-metals, whereas metallic connections happen between metal atoms. The metallic bonding joins metal atoms.
