Answer:
6. this is because atomic mass 11 - atomic number 5 is equal to 6 neutrons.
Answer:
46.85kJ
Explanation:
The specific latent heat of vaporization of water is =2.3 x 10⁶ J kg-1.
The specific heat capacity of water = 4.2×10³J/kgK
The latent heat of fusion of water= 3.36×10⁵ J/kg
The specific heat capacity of ice=2.108×10³ J/kgK
The heat of lost due to cooling of ice is calculated as follows by adding the heat lost during condensation of water vapor to the heat lost during cooling the water to freezing point plus the heat lost during freezing plus the heat lost during cooling the ice to -32.0°C
=MLv+MCΔT(water)+MLf+MCΔT(ice) where Lv=latent heat of vaporization of water , and Lf is the latent heat of fusion ice.
=(0.015kg×2.3 x 10⁶ J/kg)+(0.015kg×4.2×10³J/kgK×100K)+(0.015kg×3.36×10⁵ J/kg)+(0.015kg× 2.108×10³ J/kgK)×32K
=34500J+6300J+5040J+1011.84J
=46851.84J
=46.85kJ
Answer:
Explanation:
Hello there!
In this case, since the calculation of density is performed by dividing the mass over volume:
Which gives us a better understanding of the degree of compactness of the object; we can find the required density in grams per cubic centimeter by applying the following dimensional analysis in the aforementioned equation:
Regards!
the second statement is the correct one quarks are needed to balance charges in all subatomic particles such as neutrons, protons and electrons
Answer:
The reagents -
Explanation:
is an electron donating group which directs the electrophile to meta position reduction of nitro group with produces amine.
Acylation of amine with produces required product.
The complete reaction is as follows.
