Answer:
D) Heat flows from the copper cube to the iron cube.
Step-by-step explanation:
The reason comes from the second law of thermodynamics:
Heat energy will flow spontaneously from an area of high temperature to one of low temperature.
When you bring two objects of different temperature into contact, heat energy always moves from the hotter to the cooler object.
The copper cube is hotter than the iron, so heat flows from the copper cube to the iron cube.
here hope this helps
Answer: The order of increasing lattice energy is 
Explanation: Lattice energy is defined as the energy required to break the intermolecular force that is responsible for the formation of a lattice.
Melting point is defined as the temperature at which solid gets converted into liquid due to the weakening of the bonds in the solid form.
- Relation between lattice energy and Melting point:
The relationship between these two is direct.
More the melting point of a compound, more will be its lattice energy.
Order of increasing Lattice energy will be:
Answer:
the speed of the wave is 96.6
Explanation:
to find do frequency x wavelength
Decomposition reactions are a type of chemical reaction that involves breaking down a compound into smaller compounds or individual elements. These reactions often involve an input of energy in the form of heat, light, or electricity to break down the compounds.
Co2 will dissolve in water if water is saturated with Co2 first then it will absorb some of CO2 it appear as less is absorb that was actually the case . this would make it appear as present of CACO3 is in original sample is lower than it will be too low
