Answer:
Heat, Q = 45 J
Explanation:
We have,
Mass of aluminium is 5 g
The temperature is raised from 22°C to 32°C.
The specific heat of aluminium is 0.90 J/g°C.
It is required to find the heat are needed to raise the temperature.
The heat required to raise the temperature is given by :
So, 45 J of heat are needed to the temperature of 5.0 g of aluminum from 22°C to 32°C.
Answer:
if you check there penetrating power it is not equal so you have to consider that when talking about there electrophilic rxn in of furan.
Explanation:
they both travel at the speed of light 3.0 *10^8m/s, and their varying wavelengths
It’s either a or b for sure
Answer:
d. Metallic
c. S
Explanation:
A metallic bond is an interatomic bond in which valence electrons are constantly moving between atoms like a sea of electrons.
- The formation of this bond type is favored by a large atomic radius, low ionization energy, and a large number of electrons in the valence shell.
- The metallic bond is an attraction between the positive nuclei of all the closely packed atoms in the lattice and the electron cloud jointly formed by all the atoms losing their outermost shell electrons.
2. The bond type described in the second problem is an ionic bond. This results in the formation of crystal lattice with strong bonds.
- It occurs between metals and non-metals
- Since Nickel is a metal, sulfur is the only given non-metal that will make it form an ionic bond.
The correct answer is C because diffusion is the movement of molecules from an area of higher concentration to an area of lower concentration.
HOPE THIS HELPS!
