Answer:
Q = 813.12 j
Explanation:
Given data:
Mass of lead = 21 g
Initial temperature = 25°C
Final temperature = 327.5°C
Amount of heat absorbed by lead = ?
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 = 327.5°C - 25°C
ΔT = 302.5°C
Specific heat capacity of lead = 0.128 j/g.°C
Q = m.c. ΔT
Q = 21 g. 0.128 j/g.°C.302.5°C
Q = 813.12 j
Since ALD is an x-linked recessive disease, women must have 2 affected x chromosomes in order to get the disease, which is unlikely because the disease is rare. Since men only have one x chromosome, they will have the disease if they inherit an affected x chromosome.
Answer:
The <em><u>Whale Shark</u></em> is the largest fish in the world. On the other hand, the largest mammal is the Blue Whale (not a fish). Hope this helps!
Answer:
Urbanization has environmental and economic advantages for humans, but also substantial disadvantages, including increased problems with physical and mental health/stress, a modified climate, water and energy management, and air pollution.
Hemoglobin is contained in red blood cells,which efficiently carries oxygen from the lungs to the tissues of the body. It also helps in the transportation of carbon dioxide and hydrogen ions back to the lungs.
