你可以进行一个反应，用固态铁和氧气生成氧化铁，测量它生成的热，列成表格。
Geologist Gerard Bond noticed that some of the sediment grains were stained with iron oxide, evidence that they originated in locales where glaciers had overrun outcrops of red sandstone.地质学家杰拉德·邦德注意到，一些沉积物颗粒被氧化铁染色，这表明它们起源于冰川覆盖红砂岩露头的地方。
iron oxide, after all, is not toxic.毕竟氧化铁是无毒的。
iron oxide pigment is a color pigment whose basic substance is the oxide of iron, such as red oxide, yellow iron oxide, black iron oxide, and brown oxide.氧化铁颜料主要指基本物质为铁的氧化物的着色颜料，如氧化铁红、铁黑、铁黄、铁棕等。
You could run the reaction, take solid iron and gaseous oxygen, form iron oxide, measure the heat of formation of it, and tabulate it.你可以进行一个反应，用固态铁和氧气生成氧化铁，测量它生成的热，列成表格。
