This change in pressure is caused by changes in air density, and air density is related to temperature.
Maalox is the trade name for an antacid and antigas medication used for relief of heartburn, bloating, and acid indigestion in which
4 ml contains
= 320mg of aluminum hydroxide
= 320mg of magnesium hydroxide
= 32mg of simethicone
recommended doses = 4 times * 2 tea spoon = 8 tea spoon/ day
given = 1 tea spoon = 5 ml
8 tea spoon = 40 ml
hence,
amount of aluminum hydroxide = 320/4 * 40 = 3200mg = 3.2 g
amount of magnesium hydroxide = 320/4 * 40 = 3.2 g
amount of simethicone = 32/4 * 40 = 320 mg = 0.32g

Answer:
Energy is transferred from one object to another when a reaction takes place.
Explanation:
Energy comes in many forms and can be transferred from one object to another as heat, light, or motion, to name a few.
The answer could be It is a well known fact that energy can neither be created and nor be destroyed but can be transformed from one form to another.
Now talking about your example in a typical light bulb electrical energy is converted into light energy and heat energy. Now when the electric current flows through the conductor/filament in the light bulb,this would cause vibrations and the free ions are more likely to go to an higher energy level,and when the ions come back to their original state,the difference in the two energy levels is usually emitted as a photon,thus light energy is obtained and the heat energy is the energy dissipated as a result of flow of electricity through the conductor.
Anything that gets transformed into light energy or in better words ElectroMagnetic Energy would be a result of this.
Full question options;
(Fe, Pb, Mg, or Ca)
Answer:
Iron - Fe
Explanation:
We understand tht metals pretty much form bonds by losing their valence (outermost electrons). But this question specifically asks for metals that lose beyond their outermost electrons; next to outermost principal energy levels.
Pb, Mg, and Ca only lose their outermost electrons to form the following ions;
Pb2+, Mg2+, and Ca2+.
This is because their ions have achieved a stable octet configuration - the dreamland of atoms where they are satisfied and don't need to go into reactions again.
Iron on the other hand has the following electronic configurations;
Fe: [Ar]4s2 3d6
Fe2+: [Ar]4s0 3d6
Fe3+: [Ar]4s0 3d5
This means ion can lose both the ooutermost electrons (4s) and next to outermost principal energy levels (3d). So correct option is Iron.
Answer:
Explanation:
An electron in 4s is farther away from nucleus and it has higher energy when compared to electron from 1s.
