Answer:
Q = 1147.5 cal
Explanation:
Given data:
Energy absorbed = ?
Mass of water = 75 g
Initial temperature = 22.5°C
Final temperature = 37.8°C
Specific heat of water = 1 cal/g.°C
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 = 37.8°C - 22.5°C
ΔT = 15.3 °C
Q = m.c. ΔT
Q = 75 g . 1 cal/g.°C . 15.3 °C
Q = 1147.5 cal
Answer:
Both b/c a chemical formula tells you how many and a sketch formula shows how they are bonded together.
Molecular formulas show how many atoms of each element one molecule of a compound contains. Note: Ionic compounds are generally crystalline solids with high melting points. Other compounds, however, have very different properties.
Answer:the first column has one valance electron the second has 2 and so on.
The only exception is helium that has 2.
