金属晶体：Cs 离子晶体：CsNO3，BaO 共价晶体：SiO2 分子晶体：N2，CO2。
百度试题 结果1 题目氧化钡在碳酸钡中的含量碳酸钡分解成CO2和BaO后,BaO在碳酸钡中的质量百分比是多少 相关知识点: 试题来源: 解析 CO3Ba=CO2+BaO 碳酸钡分子量197,氧化钡153 所以153/197=77.66%反馈 收藏
③ 硬度:SiC > BaO > CO2 因为SiC是原子晶体,微粒间以牢固的共价键相结合,强度较大,所以硬度较高。 BaO是离子晶体,微粒间的作用力是离子键,因此也有较高硬度。CO2是分子晶体,微粒间靠很弱的范德华力联结,所以硬度很低。反馈 收藏

Garnet-type Li6.5La3Zr1.5Ta0.5O12 (LLZO) is considered a promising solid electrolyte, but the surface degradation in air hinders its application for all-solid-state battery. Recent studies have mainly focused on the final products of the LLZO surface rea
故答案为:BaO与CO2反应生成BaCO3,覆盖在BaO表面; ②当CO2体积分数达到10%~20%时,氮氧化物吸收率依然较高,原因可能有:BaCO3在一定程度上也能吸收NOx, 故答案为:BaCO3在一定程度上也能吸收NOx; ③若柴油中硫含量较高,在稀燃过程中,BaO吸收氮氧化物的能力下降至很低水平,结合化学方程式解释原因:稀释过程中,柴油中...
