The document discusses the bonding and properties of hydrogen halide molecules. It explains that hydrogen halides form polar covalent bonds due to the higher electronegativity of the halogen atoms. Intermolecular forces between hydrogen halide molecules include dispersion forces, dipole-dipole attractions, and strongest hydrogen bonding. Hydrogen fluoride is anomalous as it exhibits weaker intermolecular forces than other hydrogen halides despite having the most electronegative fluorine atom.

The Hydrogen Halides. Aim: To understand the bonding in hydrogen halide molecules and the intermolecular forces that exist between the molecules To explain and identify the trend in boiling points for Hydrogen halides. To understand the acidic nature of the hydrogen halides

Determination of enthalpy of ionisation of acetic acid

Mithil Fal Desai

The acetic acid is a weak acid as it does not completely dissociate in dilute aqueous solutions into hydrogen (H+) and acetate (CH3COO-) ions. When acetic acid is neutralized with a strong base (NaOH), heat is evolved during the neutralization that is used in the process of dissociating the acetic acid further that will facilitate the completion of neutralization. CH3COOH + NaOH = CH3COONa + H2O + heat The enthalpy change associated with the neutralization of acetic acid with a strong base is lower than that of the enthalpy of neutralization of a strong acid with a strong base. The difference in the enthalpy of neutralization of a strong acid (HCI) with a strong base (NaOH) and enthalpy of neutralization of weak acid (CH3COOH) with a strong base (NaOH) is the enthalpy of ionization of the weak acid (CH3COOH).

Securing your Kubernetes cluster_ a step-by-step guide to success !

KatiaHIMEUR1

Today, after several years of existence, an extremely active community and an ultra-dynamic ecosystem, Kubernetes has established itself as the de facto standard in container orchestration. Thanks to a wide range of managed services, it has never been so easy to set up a ready-to-use Kubernetes cluster. However, this ease of use means that the subject of security in Kubernetes is often left for later, or even neglected. This exposes companies to significant risks. In this talk, I'll show you step-by-step how to secure your Kubernetes cluster for greater peace of mind and reliability.

Neuro-symbolic is not enough, we need neuro-*semantic*

Frank van Harmelen

Neuro-symbolic (NeSy) AI is on the rise. However, simply machine learning on just any symbolic structure is not sufficient to really harvest the gains of NeSy. These will only be gained when the symbolic structures have an actual semantics. I give an operational definition of semantics as “predictable inference”. All of this illustrated with link prediction over knowledge graphs, but the argument is general.

Effective Application Security in Software Delivery lifecycle using Deployment Firewall and DBOM The modern software delivery process (or the CI/CD process) includes many tools, distributed teams, open-source code, and cloud platforms. Constant focus on speed to release software to market, along with the traditional slow and manual security checks has caused gaps in continuous security as an important piece in the software supply chain. Today organizations feel more susceptible to external and internal cyber threats due to the vast attack surface in their applications supply chain and the lack of end-to-end governance and risk management. The software team must secure its software delivery process to avoid vulnerability and security breaches. This needs to be achieved with existing tool chains and without extensive rework of the delivery processes. This talk will present strategies and techniques for providing visibility into the true risk of the existing vulnerabilities, preventing the introduction of security issues in the software, resolving vulnerabilities in production environments quickly, and capturing the deployment bill of materials (DBOM). Speakers: Bob Boule Robert Boule is a technology enthusiast with PASSION for technology and making things work along with a knack for helping others understand how things work. He comes with around 20 years of solution engineering experience in application security, software continuous delivery, and SaaS platforms. He is known for his dynamic presentations in CI/CD and application security integrated in software delivery lifecycle. Gopinath Rebala Gopinath Rebala is the CTO of OpsMx, where he has overall responsibility for the machine learning and data processing architectures for Secure Software Delivery. Gopi also has a strong connection with our customers, leading design and architecture for strategic implementations. Gopi is a frequent speaker and well-known leader in continuous delivery and integrating security into software delivery.
