Answer:
It loses kinetic energy.
Explanation:
The definition of heat is molecules moving fast, so it cooling would mean they slow down.
Answer:
Molecular
C6H8 has the empirical formulae as <em>C3H4</em>
Both chloro and methyl groups axial
More stable
Higher concentration
Answer:
6. d, 7. a
Explanation:
6. Molarity is a number of moles solute in 1 L solution.
7. 1 L solution - 2.5 mol K2CO3
20 L - x mol K2CO3
x =20*2.5/1 = 50 mol K2CO3
Molar mass(KCO3) = M(K) + M(C) + 3M(O)= 39 +12 +3*16= 99 g/mol
99 g/mol *50 mol = 4950 g KCO3 Closest answer is A.
Actually KCO3 does not exist, in reality it should be K2CO3.
This is due to the different properties of the depth of the earth. The interior of the earth is made of heavier metals such as nickel and is hotter than the upper layers. The great pressure in these deep depths keep the elements from melting even at very high temperatures. The upper layers are made up of lighter elements such as iron and magnesium - and are less dense. These layers experience less pressure and temperatures than the deep interiors. Therefore their properties is a bit different. This also allows these layers to be semi-plastic than the soil core.
