How are volcanic mountains formed?
astra-53 [7]

Answer:

Volcanic mountains form as lava oozes forth from cracks in the earth. The lava builds up around the area where the eruption occurred. Layers build upon layers and over a period of time, a volcanic mountain forms. There are several ways that volcanic mountains are formed. Shield volcanoes, which are very wide with a gentle slope, are formed by long periods of eruption with low-viscosity lava.

When 24g of magnesium metal is heated in air, 40g of magnesium oxide is produced. What mass of magnesium would be needed in orde
inysia [295]

Answer: 6.1 g

Explanation:

between Mg and MgO theres a 1;1 MOLE RATIO

here's the balanced equation

2Mg + O2 ==> 2MgO

24g of magnesium is approximately 1 mole of magnesium so it produces 40 g of mgo which is also 1 mole of mgo thus 10/40 =0.25 moles of MgO so 0.25 moles of magnesium would be needed  which is approximately 6.1 g

sergejj [24]

When you see a long dash joining two elements in the structural formula of a chemical molecule you can assume that the chemical bonds in the compound are simple bonds.

In the representation of chemical molecules long dashes are used to represent simple bonds since these bonds are longer than double and triple bonds, which are represented by = and ≡ respectively.

How does the composition of a mixture of hydrogen and oxygen differ from the composition of a compound containing hydrogen and o
IrinaK [193]
Chemical compounds have chemically bonded molecules so that they exhibit different properties (i.e. chemical) compared to the individual molecules comprising the compound. Mixtures are simply the combinations of different molecules and compounds that are not chemically bonded together, and can therefore be separated by physical means. Mixtures usually retain the properties of its components. 

The hydrogen and oxygen molecules in a mixture do not form strong bonds between each other. The molecules of both gases are only contained in the same space or volume and the individual molecules retain their chemical properties. 

A compound containing hydrogen and oxygen molecules exhibit different chemical (and even physical) properties compared to the individual molecules themselves.

Water for example, is a compound with 2 hydrogen atoms and 1 oxygen atom, chemically-bonded together. Hydrogen gas is highly flammable, water is not. Oxygen gas is an essential reagent for combustion (or burning) reactions, water is not. 
 
Thus, throwing a lighted match to a gaseous mixture of hydrogen (H_{2}) and oxygen (O_{2}) would create fire, or even an explosion (since hydrogen is flammable and oxygen feeds the reaction). Throwing a match to water vapor (H_{2}O) would not create fire.
