a目前常用的熔盐是一种三元无机盐类[8]:由53%KNO3、40%NaNO2和7%NaNO3熔化后形成的熔体混合物,属于危险类物品。熔盐与导热油相比,在相近的压力下可获得更高的使用温度(350~600℃),且有较好的热稳定性,其导热系数是其他有机热载体的两倍,而且温度在600℃以下时,几乎不产生蒸汽,这是熔盐得性能优于导热油得所在...
The ones that do are called ions. In general, the electric charge of an atom or a molecule can be determined by looking at the ratio between its protons and electrons.Answer and Explanation: In acid-base reactions that involve the ions ...
Amphoterism refers to the acid and base reactivity of a single substance. In the presence of an acid, the substance will act as a base, while in the presence of a base, it will assume the action of an acid. A famous example of an amphoteric substance...
aAt present the commonly used fused salt is one kind of three Yuan inorganic salts (8): After 53%KNO3, 40%NaNO2 and 7%NaNO3 melt the melt mixture which forms, belongs to the danger class goods.The fused salt and the heat conduction oil phase compared to, may obtain the higher application...
While the precise chemistry involved in the process remained obscure for nearly 100 years, it was later found to consist of several steps: a) 2 NaCl (salt) + H2SO4 (sulfuric acid) => Na2SO4 (saltcake, intermediate) + 2 HCl (hydrochloric acid gas, a file:///D|/pafko.com/www/...
The solubility rules predict the ability of an ionic compound or a salt in an aqueous solution. Answer and Explanation: Answer: Carbonates Based on solubility rules, carbonates are generally insoluble in water except carbonates formed by Group II metal cati...

Amino-acid replacement of the unique ion-selective motif of HvCNGC2-3, AQGL, with the canonical motif, GQGL, resulted in the abolition of the current. This study reports a unique two-ion-dependent activation characteristic of the barley CNGC, HvCNGC2-3. Keywords: cyclic nucleotide-gated ...
