Correct Answer: An acid can be defined as a molecule or other species which can donate a proton or accept an electron pair in reactions (OR) A substance with particular chemical properties including turning litmus red, neutralizing alkalis, and dissolving some metals; typically, a corrosive or sour-tasting liquid of this kind
Correct Answer: Ion
Explanation:
An atom that loses or gains electrons is called as ion. Gaining of electron is negative charge and is called as Anion and lossing of eectron is called Cation.
Correct Answer: Ionic
Correct Answer: Carbon dioxide
Explanation:
Carbon dioxide is present under pressure in soft drinks.
Correct Answer: Chlorine
Explanation:
Gammaxene, D.D.T. & Bleaching powder are important compounds of Chlorine.
Correct Answer: increase in water cement ratio
Explanation:
Strength of concrete increases with increase in water cement ratio as the strength of the cement is directly proportional to water cement ratio.
Correct Answer: Lipids
Correct Answer: Law of conservation of mass
Explanation:
Stoichiometry is a branch of chemistry deals with the calculations on reactants and products. It is based on the Law of conservation of mass where total mass of reactants is equal to total mass of products.
Correct Answer: FALSE
Explanation:
Alcohol is a drug.
Correct Answer: All of the above
Explanation:
A substance that dissociates into ions in solution and acquires the capacity to conduct electricity. Sodium, potassium, chloride, calcium, and phosphate are examples of electrolytes, informally known as lytes.
