Act FAST when a stroke strikes! Learn about the importance and symptoms. A stroke is an attack occurring in the brain, and it's one of the leading causes of death and adult disability worldwide. Yet up to 80% of strokes can be prevented. In this video we explain what you should do in the event of a
The formulas of the salts represent ratio formulas. It describes the ratio of cations to anions. Here it is explained how to arrive at these ratios and how salt formulas can be established as a result. The naming is more of a minor matter here. Original: "Wolfgang Dukorn" Original: German. All tra
We explain how to recognize and treat a heat stroke. We also look into the risk groups and how to prevent it from happening. Summer is the time of heatwaves and a heat stroke is a serious medical emergency. Always remember to drink a lot of fluids! Click here to see more videos: https://alugha.com/
Ha two O! This is the spoken formula of water. What does this mean and how can it be applied to other molecules? This screencast is about the formula notation of molecules. It is not a question of why the molecules in question are built the way they are. Original: "Wolfgang Dukorn" Original: Germa
We can derive expressions and equations from sentences, and also we can derive formulae such as area and volumes, or quadratics. In this video, we're going to look at deriving formulae. You are usually given information in a diagram or sentences and asked to "show that". Ignore the "show that" as th
How are Lewis formulas (valence formulas) set up? The electron octet (duplet for hydrogen) and the total number of electrons must be observed! Original: "Wolfgang Dukorn" Original: German. All translations in this video have been done by the alugha AI.
Expressions, equations, formulae and identities are all slightly different types of algebraic notation. In this video we’re going to discover the differences. An expression is a collection of letters and numbers, with no equals sign. An equation is two expressions that equal each other, and so can b
Lewis formulas describe the connections of atoms within a molecule. This screencast describes how these formulas can be determined when different types of atoms are involved. Original: "Wolfgang Dukorn" Original: German. All translations in this video have been done by the alugha AI.
In this video we are going to look at how to change the subject of a formula, when the subject appears twice. We have already looked at how to change the subject in another video, so you may want to watch that first. We always use opposites: adding and subtracting, multiplying and dividing, squaring
