Answer:
2. terms in science are derived from greek or latin worda
Explanation:
because it's helpful to create new words, for different diseases or discoveries from a "dead language" which won't be ever changing
Our planet's magnetic field is believed to be generated deep down in the Earth's core. The Coriolis force, resulting from the Earth's spin, also causes swirling whirlpools. This flow of liquid iron generates electric currents, which in turn produce magnetic fields.
Hope this helps!
Answer:
Explanation:
The volume and number of moles are constant, so we can use Gay-Lussac’s Law:
At constant volume and number of particles, the pressure exerted by a gas is directly proportional to its temperature.
Data:
p₁ = 0.500 atm; T₁ = 315 K
p₂ = 0.750 atm; T₂ = ?
Calculations:
Answer:
H2O> NH3>CH4
Explanation:
Now let us look at the issue of the approximate bond angles of each specie;
H2O- 104°
NH3 - 107°
CH4 - 109°
We can see that both species are based on a tetrahedron on the basis of electron pair geometry. How ever, we must also remember that lone pairs cause more repulsion around the central metal atom atom and distort the bond angles. Thus, in the presence of lone pairs, molecules depart from the expected shape predicted by valence shell electron pair repulsion theory. Hence, the repulsion of lone pairs in water (2 lone pairs) is greater than the repulsion in ammonia (1 lone pair) and repulsion in ammonia is greater than the repulsion in methane (no lone pair).
