A 175 g lump of molten lead at its melting point (327° C) is placed into 55.0 g of water at 20.0°C. The specific heat of
lead is 130J/kg°C and the Hf of lead is 20,400 J/kg. When
the lead has become solid but is still at the melting point, what
is the temperature of the water?

whitney would be experiencing fear or unintentional terror

d.   is 3

i hope that ! =)

im srry but ur wrong the answer is d a smooth rock, some red dirt, and an empty bird's nest.

it is given that trillions of microbes make up to 1% to 3% of the body mass.

let's take average of this percentage: 2%

consider the average mass of the human body as 70 kg.

then, trillions of microbes would have mass  

therefore, 100 trillion micro-organisms would weigh:

this is an approximate value and could change depending on the mass of the human body and percentage of the microbes present in it.

average mass per microorganism =
