From the equation q=mCΔT, set the q of copper = to q of water,
So --- mCΔT(copper)=mCΔT(water).
mass (Cu - copper) = 38g
mass (H2O - water) = 15g
C (H2O) = 4.184 J/g*C
ΔΤ (H2O) = 33-22 = 11*C
ΔΤ (Cu) = 33-80 = -47*C (the final temp is the same for both materials - thermal equilibrium)
C (Cu) = ?
So --- 38(-47)C[Cu]=15(4.184)(11)
--- C[Cu]=690.36/(-1786) = 0.3865 J/g*C, or 0.39 in 2 sig figs. (The negative goes away, because specific heats are usually positive)
Three examples of arthropods are, a crab, a centipede, and a spider. I know a crab is a arthropod because crabs have an external skeleton. Like armor, it protects the arthropods body. When arthropods are born the exoskeleton is soft but hardens quickly and it can be shed as the creature grows. Arthropods are invertebrates; which means that they do not have a backbone. I also know a centipede is a arthropod because they can have many jointed legs or limbs. Spiders have 8 legs, millipedes can have... Hundreds! I know a spiders are a arthropod because they have a segmented body. This means that they will have a body made up of more than one part. Spiders have two segments and flies have three segments.
Answer:
I think it is liquid's only.

Answer:
Formaldehyde is highly soluble in water.
Explanation:
Formaldehyde is the simplest of the aldehydes (R−CHO) it is an organic compound which occurs naturally with the formula H−CHO. . The IUPAC name of formaldehyde is methanal.
Formaldehyde at room temperature is a colorless gas and the liquid is invisible or like white-water. Formaldehyde has an irritating and very pungent like odour. Formaldehyde is very soluble in water.
Now according to Henry's constant law (3 × 10-5 kPa·m3/mol) Formaldehyde will be very unlikely to volatilize from water.and hence, Formaldehyde is considered to be highly soluble in water.
