Answer:
(b). All carbohydrates have the general formula ![C_{n}(H_{2}O)_{n}](https://tex.z-dn.net/?f=C_%7Bn%7D%28H_%7B2%7DO%29_%7Bn%7D)
Explanation:
Carbohydrates, more commonly known as sugars, are made up of carbon, oxygen, and hydrogen atoms. As mono-saccharide is known as the smallest unit of a carbohydrate . Two monosaccharides make up a disaccharide, and many monosaccharides make up a polysaccharide. Disaccharides and polysaccharides can be hydrolyzed back into the individual monosaccharide units.
As we know that the carbohydrate is always represented as
,
where n is any number between three and eight.
Hence, the option (b) is incorrect.
Answer:
0.010
Explanation:
Significant Figures Rules:
1. Anything that isn't a zero is a sig fig
2. If a decimal point comes after the ones digit, everything before the decimal is counted as sig fig (i.e 2000. would be 4 sig figs).
3. If we are dealing with small decimals, the zero before and after the decimal (i.e 0.002) is a placeholder and is not counted as sig figs.
4. Any zeros between 2 significant digits is considered in sig figs (i.e 2002 would be 4 sig figs)
5. Any zeros after a significant digit in a decimal (i.e 0.020) is considered a sig fig
0.0102 would be 3 sig figs. Rounding to the thousandths place of 0.010 would be 2 sig figs.
ummm I'm not sure but I hope you get help soon
Answer: -
Solubility of a substance depend on the balance of intermolecular forces between the solvent and solute, and the entropy change that accompanies this process.
Temperature and pressure also plays a role in solubility.
A solution having Group 1 cations like lithium, sodium, potassium etc are always soluble.
A solution having NH₄⁺ is soluble.
All salts with anion as nitrates, acetates, chlorates, and perchlorates are soluble in water.
