Answer: C. Electrochemical cells involve oxidation-reduction reactions.
Explanation: Oxidation occurs at the anode, and reduction occurs at the cathode.
Answer: Anabolism
Explanation:
Chemical reactions that combine simple molecules and monomers to form complex structures are known as ANABOLISM.
Anabolic reactions which are also called biosynthesis reaction is a type of metabolic reaction in the body that forms larger molecules through combination of smaller molecules with the use of energy in the form of ATP molecules. Example if anabolic reactions in the body includes:
- formation of polysaccharide from monosaccharides,
- formation of triglycerides from fatty acids,
- formation of nucleic acids from nucleotides and many among others. I hope this helps, thanks.
The temperature would slowly decrease until the bowl's internal temperature matches the refrigerator's internal temperature.
I hope this is the answer you needed.
Answer:
it is because a number of factors, including sample surface cleanliness and temperature, can prevent chunks of alkali metals from exploding on contact with water. The team eliminated those variables and others by using a sodium-potassium alloy that remains liquid at room temperature and a droplet delivery system featuring a calibrated syringe.
The equation to be used to
calculate the heat absorbed when solid melts is the enthalpy of melting. It is
represented as H
= mCpT where H is the heat
released after phase change, m is the mass of the substance, Cp is the specific
heat capacity of the substance and T
is the change in temperature.
H
= mCpT
H
= (18g/1000g/kg)(4.184kJ/kg-K)(293-(-263))
H
= 41.87kJ
