We combine the two equations, like we would any mathematical system of equations. After addition of the two equations, we get:
Mg + 2H⁺(aq) + 2e⁻ → Mg⁺²(aq) + H₂(g) + 2e⁻
Cancelling like terms from both sides
Mg + 2H⁺(aq) → Mg⁺²(aq) + H₂(g)
B. A bond between two atoms: it doesn't matter if it's positive or negative or neutral, if there is a bond between two atoms, it is covalent.
Answer:
D- Traits higher on the tree developed before traits lower on the tree.
Explanation:
The answer is D because the higher/stronger a trait is it will be developed before any lower traits.
The answer is B.) Energy directly from the sun to both producers and consumers.
Answer:
Water droplets form on plants, allowing the plants to soak up the water over time rather than all at once.
Explanation:
Cohesion and Adhesion are the properties of water which affect the living and non-living on earth.
Cohesion means water is attracted to water.
Adhesion means water is attracted to other living beings.
Water is very cohesive in that it "sticks" to itself. Cohesion is what allows a water droplet to form, for example. When water molecules surround one another, they settle toward a low energy state. For water molecules, they are most stable when they form a ball surrounded by other water molecules. As the molecules "pull" together, the surface tension acts like a casing for the group of water molecules. If it weren't for cohesion, water molecules would behave very differently and we would not expect to see water droplets.
Cohesive and adhesive properties of water impact living things in many ways:
Water droplets form on plants, allowing the plants to soak up the water over time rather than all at once.
Water striders (insects) glide across water surfaces owing to the cohesive property of water.
