Answer:
lithosphere
Explanation:
Earth's interior layers are ordered by density. The densest layer is the solid metal inner core, the mantle is of intermediate density, and the least dense layer is the lithosphere, particularly the continental lithosphere.
Exothermic is a chemical reaction in which heat is released. Lighting a candle is an example of an exothermic because the flame is the heat being released.
CH4 + 2O2 -> 2H2O + CO2
You need to add a 2 in front of the O2 and H2O in order to balance the equation.
Answer:
cylinder A has a higher density then cylinder B or more accurately the liquid in cylinder A is denser then the liquid in the second tube.
Explanation:
"Denser" simply means more matter is contained in the same space for example say you fill a tank with helium and another tank with water. Although they are the same size one will weigh much more because their is more particles or "stuff" inside the same area this can be because of a few things one it can be because the atoms or elements that compose the substance are heavier containing more electrons and protons in their orbit. or the molecular structure is more compact like a chicken wire fence has more wire in it then a barbed wire wire fence covering the same area because of the grid of wire in the middle.
Answer:
B. a substance that can accept a proton from an acid
Explanation:
Johannes Brønsted and Martin Lowry independently developed definitions of acids and bases based on compounds abilities to either donate or accept protons (H+ ions).
The acid is the donor of the hydrogen ions while the bass is the acceptor of the hydrogen ions.
Back to the options, the correct option is B. Which is a substance that can accept a proton from an acid. All other options are incorrect.
