what lab tools are pictured below and why should you always use them when working with heated glassware.

Explanation:

The top tool is a pair of forceps (or tongs) and the bottom is a wire gauze (or a beaker tongs? Wait, the bottom looks like a wire gauze or maybe a heat-resistant pad? Wait, no, the bottom image—wait, actually, when working with heated glassware, you use tongs (the top tool, which is a pair of forceps or beaker tongs) to handle heated glassware to avoid burns, and a wire gauze (or a heat-resistant mat) to place heated glassware on to protect the lab bench. Wait, the question is: identify the lab tools and why use them with heated glassware.

First, the top tool: it's a pair of tongs (beaker tongs or crucible tongs). The bottom tool: it's a wire gauze (or a heat-resistant pad, but wire gauze is used to support glassware and distribute heat). Wait, no, the bottom image—looking at the picture, the bottom one is a wire gauze (with a ceramic center) or maybe a beaker tongs? Wait, no, the top is a pair of tongs (used to hold heated glassware, like beakers or flasks, to prevent direct contact with hands, avoiding burns). The bottom: if it's a wire gauze, it's used to place heated glassware on to protect the lab surface and ensure even heating. But the question is "What lab tools are pictured below and why should you ALWAYS use them when working with heated glassware."

So the top tool is tongs (to grip and move heated glassware, preventing burns from touching hot glass). The bottom tool: if it's a wire gauze, it's used to support the glassware and distribute heat, or a heat-resistant mat. Wait, maybe the bottom is a wire gauze (used under glassware when heating with a flame, to prevent thermal shock, but when handling heated glassware, tongs are used to hold it, and a wire gauze or heat pad to place it on.

So the two tools: 1. Tongs (top) – use to hold heated glassware to avoid burns (hands don't touch hot glass). 2. Wire gauze (bottom) – use to place heated glassware on to protect the lab bench from heat and prevent the glass from cracking due to rapid temperature change (if placing on a cold surface).

Wait, the question is to identify the tools and why use them with heated glassware. So first, identify the tools: top is tongs (beaker tongs), bottom is wire gauze (or a heat-resistant pad). Then explain: Tongs are used to handle heated glassware to prevent direct contact with hands, avoiding burns. Wire gauze (or the bottom tool) is used to place heated glassware on to protect the lab surface and provide a stable, heat-distributing surface to prevent thermal shock (if the glass is placed on a cold surface, it could crack).

But maybe the bottom tool is a wire gauze, which is used when heating glassware with a flame (to support it), but when handling heated glassware, tongs are essential to move it, and a wire gauze to rest it on.

So the answer: The top tool is a pair of tongs (or beaker tongs), used to grasp and move heated glassware to avoid burns from direct contact. The bottom tool is a wire gauze (with a ceramic center), used to place heated glassware on to protect the lab bench from heat damage and to help distribute heat evenly, preventing thermal shock to the glass.

Answer:

The top tool is tongs (used to grip heated glassware, avoiding burns from direct contact with hot glass). The bottom tool is a wire gauze (used to support heated glassware, protecting the lab surface and preventing thermal shock by distributing heat or providing a heat-resistant surface to rest the glassware on).

Always use tongs to handle heated glassware (to prevent burns) and a wire gauze (or heat - resistant surface) to place it on (to protect the lab bench and the glassware from damage due to rapid temperature changes).
