M=7M(H₂O)
M=7*18.015 g/mol = 126.105 g/mol
Answer: [Kr] 5s24d10 is the element Cadmium, Cd. It has 48 electrons.
A substance undergoing thermal expansion will expand when heated, substances will mostly expand when heated but when their cold it will undergo contraction.
Answer:
See explanation
Explanation:
The most accurate method of determining the volume of an object, is the water displacement method. It has the peculiar advantage of working well with irregular solids.
There are often errors that prevent exact measurements of the volume of objects. This makes the water displacement method a preferred and easier method of determining the volume of an object.
Answer is: 9623.85 kJ of heat is <span>transferred from iron ingot.
</span>m(Fe) = 24.7 kg · 1000 g/kg = 24700 g; mass of iron ingot.
C = 0.4494 J/g°C; t<span>he specific heat of iron
</span>ΔT = 880°C - 13°C; temperature <span>difference.</span>
ΔT = 867°C.
Q = m·C·ΔT.
Q = 24700 g · 0.4494 J/g°C ·867°C.
Q = 9623856.06 J ÷ 1000J/kJ.
Q = 9623.85 kJ.
