Store dehydrated powder in a dry place in tightly-sealed containers at 2-25 °C. Directions: Dissolve 16 g in 1 litre distilled water and sterilize by autoclaving at 121°C for 15 minutes. After cooling to 45-50°C mix 4.5 ml liquid broth with either 0.5 ml filter sterilized 5% L-Rhamnose solution (madeRead More →
Dodecane is a colorless liquid that has a boiling point of 421.3° F at 760 mm Hg and a melting point of 14.7° F. It is very soluble in ethyl ether, ethyl alcohol, carbon tetrachloride, and chloroform. Does decane mix with water? Decane is a component of gasoline (petrol) andRead More →
Carbon tetrachloride is a non polar covalent compound which consists of only molecules as a result due to lack of free ions it does not dissolve in water. Does CCl4 dissolve in H2O? Insoluble: CCl4 is nonpolar only has London dispersive and H2O is polar which all there London dispersive,Read More →
Sugar and ethanol are covalent compounds that are soluble in water, because they contain O-H groups that can H-bond to the water. Nonpolar compounds like hydrocarbons have weak intermolecular attractive forces. For example, hexane, C₆H₁₄, does not dissolve in water. Are ionic or covalent compounds more soluble in water? IonicRead More →
At acidic pH, phenylhydrazine occurs as the salt (BUA, 1995). In the atmosphere, phenylhydrazine would exist solely in the vapour phase (HSDB, 1998). How do you make phenyl hydrazine hydrochloride solution? Dissolve 15 g PMA in 500 mL distilled water, allow to stand one day, and filter before use throughRead More →
1. Add 100 mg of Gibberellic Acid 3 Quick-Dissolve™ (GoldBio Catalog # G-120) to a 250 mL beaker. 2. Add 100 ml of molecular biology grade water and stir until dissolved to make a final concentration of 1 mg/ml (1000 ppm). How do you apply gibberellic acid to plants? GibberellicRead More →
Methanol is a polar compound. It is soluble in water but insoluble in oil. Why is methanol more soluble in water? Because of the strength of the attraction of the OH group, first three alcohols (methanol, ethanol and propanol) are completely miscible. They dissolve in water in any amount. WhyRead More →
Because Tums contains calcium, swallowing them whole is like taking a calcium supplement, and calcium supplements have been linked to a higher risk of heart attack, especially in people with heart disease. You should not swallow Tums whole. How do you take Tums correctly? Take Tums exactly as directed. DoRead More →
Because the difference between the electronegativities of carbon and hydrogen is small (EN = 0.40), hydrocarbons are nonpolar. As a result, they do not dissolve in polar solvents such as water. Hydrocarbons are therefore described as immiscible (literally, “not mixable”) in water. Why are hydrocarbons insoluble in water? Explanation: “LikeRead More →
Take mirtazapine close to bedtime because it may cause sleepiness. You can cut or crush the immediate-release tablets. You cannot cut or crush the orally disintegrating tablets. Can you chew Remeron? Do not chew, break, or crush it. Do not take this medicine (mirtazapine orally disintegrating tablets) out of theRead More →
