Answer:
hyaluronic phosphoric acid
Answer:
same, different
Explanation:
Resonance structures have _same______ connectivity of atoms and __different_____ distribution of electrons.
Resonance structures are obtained in molecules where the atomic positions are the same but the electrons joining the atoms keep on delocalising. Usually, none of the resonating structures can fit the molecule or ion. This implies that the real structure is the hybrid of all the possible structures.
Acid rain makes waters acidic, and causes them to absorb the aluminum that makes its way from soil into lakes and streams. This combination makes waters toxic to crayfish, clams, fish, and other aquatic animals.
Answer:
Q = 27060 j
Explanation:
Given data:
Mass of sample = 120 g
Initial temperature = -10.0 °C
Final temperature = 100 °C
Heat added = ?
Solution:
Formula:
Q = m.c. ΔT
Q = amount of heat absorbed or released
m = mass of given substance
c = specific heat capacity of substance
ΔT = change in temperature
ΔT = T₂ - T₁
ΔT = 100- (-10)
ΔT = 110°C
Q = m.c. ΔT
Q = 120 g × 2.05 g/J.°C × 110°C
Q = 27060 j
Answer:
dissolved
Explanation:
The figure shows sodium chloride is in solution. It gets that way by being dissolved.
