Answer: Albedo
Explanation:
((Earth's normal albedo is about 0.3.)))
At the end of the day, around 30 percent of approaching sunlight based radiation is reflected go into space and 70 percent is consumed.
It works best on metals and in things like metal spoons on a stove.
Answer:
The mass of reactants and products are equal hence the reaction obeys law of conservation of mass
Explanation:
The law of mass conservation states that for a closed system to all transfer of mass, the mass of system must remain constant over time. This means for a chemical reaction, the mass of reactants must equal the mass of products.
if 2.796g of Zn reacts with 2.414g of sulphur to produce 4.169g of ZnS ad 1.041g of unreacted sulphur, then it means that accorfing to the law of mass conservation, the mass of reactants (zinc and sulphur), must be equal to mass of products (zinc sulfide and unreacted sulphur)
Mass of reactants = 2.796g + 2.414g =5.21g
Mass of products = 4.169g + 1.041g=5.21g
Answer:
A, C and D
Explanation:
Lewis acid are compounds that accept a pair of non-bonding electron while Lewis base are compound that donate non-bonding electron pairs. Lewis acid in the options are NaHCO₃ because it has both acidic and basic properties ( ampholyte), (CH3CH2)2HC+ is deficient of electron and BBr3 because boron has an incomplete octet configuration and deficient of two electron
