G11 atomicstructures
This document provides an overview of topics related to atomic structure that will be covered over 4 hours including:
- Definitions of atomic number and mass number
- Properties of isotopes and radioisotopes
- How a mass spectrometer works and calculations involving relative atomic masses
- Different regions of the electromagnetic spectrum in terms of frequency, wavelength, and energy
- Continuous and line spectra and how they relate to energy level transitions in atoms
Linkedin Overview
This document provides an overview of LinkedIn and its products and services. It discusses LinkedIn's core profile and group features, as well as search, company and product pages, jobs, and mobile offerings. It also outlines LinkedIn's technologies including its core tech stack, distributed storage, search and indexing systems, databases, and open source contributions. Company culture is noted as valuing hack days, innovation, speed, and balancing hard work with play.
G11 s lequilibria
The document discusses the position of equilibrium in chemical reactions. It states that if a dynamic equilibrium is disturbed, the position of equilibrium will move to counteract the change according to Le Chatelier's principle. Specifically, it provides examples of how the equilibrium position would change if ammonia, hydrogen, or nitrogen were removed from the ammonia synthesis reaction, or if pressure or temperature were increased. It also notes that while catalysts speed up the rate of the reaction, they do not change the equilibrium position.
Sl kinetics
1. The document discusses collision theory and how various factors affect the rate of a chemical reaction. It defines rate of reaction and lists collision frequency, number of particles with energy greater than or equal to the activation energy, and proper collision geometry as factors that reaction rate depends on.
2. It explains Maxwell-Boltzmann distribution and how increasing temperature, concentration, pressure, decreasing particle size, or adding a catalyst can increase the rate of reaction by altering the distribution.
3. It defines a catalyst as a substance that speeds up a reaction by providing an alternative reaction pathway with a lower activation energy, but is unchanged at the end and recovered in the same amount.
Autobiografía k
The document discusses the concepts of "yo" (self) and "otro" (other) and how we define ourselves in relation to others. It explores how we perceive both ourselves and people different from us, and how this affects our interactions and relationships. Our understanding of others is shaped by our own biases and experiences just as others view us through their own unique perspectives.
Acids,bases
Acids and bases are classified as strong or weak. Acids react with metals, bases, and carbonates. Acids turn litmus paper red. Bases react with acids and ammonium salts. Strong bases are more reactive than weak bases. Neutral conditions with a pH of 6.3-6.8 provide an optimum environment for bacteria growth and organic matter decay.
G11 ia design
This document provides guidelines for designing a chemistry experiment to investigate the effect of changing one variable on another. It specifies that the experiment must:
1) Identify a research question involving an independent and dependent variable.
2) Describe the method for controlling and measuring these variables using bullet points and enough detail that another scientist could repeat it.
3) Target collecting data from 5 trials, with each trial repeated in triplicate, to minimize random errors. The method should also avoid issues that could prevent collecting relevant data.

Inside the world of passive talent - Research tips
The document discusses strategies for recruiting passive talent. It outlines 10 ways to successfully recruit passive candidates, including getting on the same page quickly with hiring managers, finding hidden talent beneath the radar, immersing yourself in a candidate's world, and keeping the door open with potential candidates for future opportunities. The strategies are based on LinkedIn research and consulting with successful recruiting customers.
Parnters Advisory Account
The Janney Partners Advisory Account provides ongoing professional investment advice and access to a wide range of securities and investment solutions. Clients work with their financial advisor to select an appropriate asset allocation and construct a portfolio consisting of stocks, bonds, funds, and other investments. Advisors then monitor the portfolio and make adjustments when needed to help clients achieve their financial goals. Rather than charging commissions per trade, the account uses a simplified annual fee structure based on assets.
Ovarian cancer
Ovarian cancer is the 10th most common cancer in women and the 5th most deadly. It often goes undetected until late stages due to vague symptoms that are frequently ignored. While 3 out of 4 women survive 1 year after diagnosis, early detection significantly improves prognosis - about half of women survive more than 5 years if caught early. Risk factors are unknown, but common symptoms include bloating, abdominal pain, and changes in menstrual cycles. Screening and treatment options were presented.
Stalking Awareness
This document discusses stalking awareness and provides information about stalking. It defines stalking and provides statistics about how common it is, particularly among younger people and women. The majority of stalking is done by someone known to the victim, often a current or former intimate partner. Stalking can have severe negative impacts on victims' mental health, safety, and employment. The document recommends actions for victims of stalking and provides resources for support.
