X、Y、Z、W是元素周期表中原子序数依次增大的四种短周期元素，其相关信息如下表：

（1）W位于元素周期表第     周期第   族；Z和W的最简单的离子半径大小关系为                   

       （用离子符号表示）

（2）一种X形成的单质，是自然界硬度最大的物质，若熔化这种单质，所需克服的微粒间的作用力是        ；Y的电负性比Z       （填“大”或“小”）

（3）W的单质与NaOH溶液反应的离子方程式为                                 ， W在高温条件下可还原高熔点的金属氧化物制的金属单质，写出W还原Cr₂O₃反应的化学方程式：                                                            。

（4）煤燃烧产生的烟气中有Y的氧化物，会引起严重的环境问题，因此，常用XH₄催化还原以消除污染，已知：

XH₄(g)+2 YO₂(g)="=" Y₂(g)+ XO₂(g)+2H₂O (g) △H₁= -867kJ/mol

2 YO₂(g) Y₂O₄(g)  △H₂=-56.9kJ/mol

Public Key Infrastructure (PKI) service providers offer organizations fully integrated PKI-managed services designed to secure Intranet, Extranet, Virtual Private Network (VPN), and e-commerce applications. PKI solutions can enable a number of security services, including p authentication and non-repudiation of transactions.
eToken enables the users of PKI systems to generate and store (101) and digital certificates inside the token, creating a secure environment and allowing full portability and maximum ease of use. eToken Pro can also perform sensitive on-chip (102) operations, ensuring that users’ keys axe never exposed to the PC environment, eToken eliminates the need to store (103) and keys on a hard disk or browser file, or to transmit them across the Internet/Extranet; assuring peace-of-mind and confidence during online communications.
A digital signature is created using the private key of an individual to ensure the Validity of his request. This technology can be used to guarantee (104) of various transactions. The strength of either the authentication level or the digital signature relies on the level of protection offered to the private key. eToken Pro offers the maximum level of security, since it enables the use of the private key for signing and authenticating inside the eToken.
The most secure use of authentication involves enclosing at least one certificate with every signed message. The message (105) verifies the certificate using the CA’s public key. If the sender’s public key is legitimate, the recipient verifies the message’s signature. Digital signatures created with a private key are verified with the digital certificate containing the public key.
