A 46 year old is brought in by EMS after a motor vehicle collision in which he was an unrestrained driver. Although he has no obvious injury to his head or neck, he complains of chest pain and appears very short of breath. His vital signs are: T 99.2 F, BP 85/57, HR 123, RR 36, SpO2 95% on non-rebreather. The CXR demostrates a tension pneumothorax. Required:
Which is the most appropriate next step in this men's care?

water is a polar molecule. a chemical bond is a force of attraction between atoms or ions. bonds form when atoms share or transfer valence electrons. atoms form chemical bonds to achieve a full outer energy level, which is the most stable arrangement of electrons. so, false

explanation:

in h2o molecule, two water molecules are bonded by a hydrogen bond but the bond between two h - o bonds within a water molecule are covalent. the greater the electronegativity difference, the more ionic the bond is. bonds that are partly ionic are called polar covalent bonds. nonpolar covalent bonds, with equal sharing of the bond electrons, arise when the electronegativities of the two atoms are equal.

frogs. the lower the ph the higher the acid content. frogs have the highest tolerance in this scenario.

enzyme active site and substrate specificity

enzymes bind with chemical reactants called substrates. there may be one or more substrates for each type of enzyme, depending on the particular chemical reaction. in some reactions, a single-reactant substrate is broken down into multiple products
