Answer: The correct option is D: Is alloyed with carbon and chromium to make stainless steel.
Explanation: Because of its physical characteristics, iron is a material that tends to oxidize easily. With the chromium alloy stainless steel is created, which for its quality can be used in the manufacture of structural steels.
Answer:
Yuki was curious if \triangle ABC△ABCtriangle, A, B, C was congruent to \triangle FED△FEDtriangle, F, E, D, so she tried to map one triangle onto the other using transformations: Yuki concluded: "It's not possible to map \triangle ABC△ABCtriangle, A, B, C onto \triangle FED△FEDtriangle, F, E, D using a sequence of rigid transformations, so the triangles are not congruent." What error did Yuki make in her conclusion?

Explanation:
<u>Basalt</u>
<em> </em><em>Formation</em> -basalt is (mineral) a hard igneous rock of varied mineral content formed when lava reaches the Earth's surface near an active volcano
<em> </em><em>Texture</em>- is fine grained so the individual minerals are not visible
<em> </em><em>Colour</em>- basalt being dark
<u>Rhyolite</u>
<em> Formation</em> -Rhyolite is a very fine-grained to glassy extrusive igneous rock. Formed in continental plates have volcanic eruptions.
<em> Texture</em>- very small than grains and are difficult to observe without using a hand lens.
<em> </em><em>Colour</em>- light in colour whether pink or grey
<u>Andesite</u>
<em> </em><u><em> </em></u><em>Formation</em>- Andesite is a fine-grained igneous rock that forms when the magma is rises up onto the surface and crystallized quickly
<em> </em><em>Texture</em>- higher than basalt and lower than rhyolite
<em> </em><em>Colour</em><em> -</em>- color is pale due to silica content
I believe that the answer is C
