Answer:
See below
Explanation:
ΔQ = m c T ΔQ = heat required(J) m = mass (g) T = C° temp change
c = heat capacity in J/g-C
Answer and Explanation:
Polar compounds are those that have an unequal sharing of electrons, causing one end to be more positively or negatively charged than the other end.
Ionic compounds are those that are made up of a positive ion and a negative ion. Clearly, we can see that if one ion is positive and the other is negative, then that would make one end of the compound more or less positively charged than the other end, which is exactly the definition of a polar compound.
That is why ionic compounds are always polar.
Bronsted base means proton or hydrogen ion acceptor.
The more negative the compound is the more is the chance of accepting hydrogen ion.
B, C and D are negatiave
While is A is neutral. SO it is the weakest
Answer - LEGEND
The legend of a map is also called the map key. It is the part included in a map to, as it were, unlock the map. The legend (or map key) gives explanation to what each symbol and color used in the map represents.
Answer:
Mass = 42 kg
Volume = 2 m^3
By using formula = Density = Mass/Volume
= 42/2
= 21/1
= 21
= 21 m^3
