Which of these solution has more solute than it can hold? Unsaturated solutions What are the two parts of solution? Parts of a Solution All solutions have two parts: the solute and the solvent. The solute is the substance that dissolves, and the solvent is the substance that dissolves the solute. Does KSP increase with […]

What is the most important chemical regulator of respiration? CO2 What are the major transport mechanism for carbon dioxide? Carbon dioxide can be transported through the blood via three methods. It is dissolved directly in the blood, bound to plasma proteins or hemoglobin, or converted into bicarbonate. The majority of carbon dioxide is transported as […]

What is the difference between mass and specific weight? The difference between mass and weight is that mass is the amount of matter in a material, while weight is a measure of how the force of gravity acts upon that mass. Mass is the measure of the amount of matter in a body. Weight usually […]

What is a pH of a solution? The pH of a solution is a measure of hydrogen ion concentration, which in turn is a measure of its acidity. Pure water dissociates slightly into equal concentrations of hydrogen and hydroxyl (OH−) ions. What are the three ways to measure pH? The pH value can be measured […]

What is the purpose of a fuse in a plug? How does a fuse work? The fuse in a plug is a safety device designed to protect the lead rather than the appliance. It is a deliberate weak link in a circuit which will ‘blow’ if an electrical appliance or extension lead draws too much […]

What are four things that affect the resistance of a wire? There are 4 different factors which affect resistance: The type of material of which the resistor is made. The length of the resistor. The thickness of the resistor. The temperature of the conductor. What is the best description for high electrical resistance? A high […]

What is an example of classical conditioning in your own life? Smartphone Tones and Vibes. You hear that tone and instinctively reach for your smartphone, only to realize it’s coming from someone else’s phone. The chime or tone is a neutral stimulus. Through classical conditioning, you’ve come to associate it with the positive feeling of […]

What are the safety precautions for hydrochloric acid? Wear a chemical-resistant apron, chemical-resistant gloves and chemical splash goggles at all times when handling HCl to protect your eyes and skin. Concentrated hydrochloric acid is toxic if inhaled, so avoid breathing it in and always handle it while under a fume hood. What are the risks […]
