Sodium and magnesium oxides are alkaline. Aluminium oxides are amphoteric (reacting both as a base or acid). Silicon, phosphorus, sulfur, and chlorine oxides are acidic. Some non-metal oxides, such as nitrous oxide (N2O) and carbon monoxide (CO), do not display any acid/base characteristics.
Answer:
Sunlight
Explanation:
Sunlight is always neccesary in photosynthesis
Answer:
V2 = 0.75 L
Explanation:
assumin ideal gas:
∴ T1 = 300K
∴ V1 = 0.500 L
∴ T2 = 450 K
⇒ V2 = ?
assuming P, n constant:
⇒ PV1 = RT1n
⇒ V1/T1 = Rn/P = K..........(1)
⇒ V2/T2 = RN/P = K..........(2)
(1) = (2):
⇒ V1/T1 = V2/T2
⇒ V2 = (V1/T1)T2
⇒ V2 = (0.500 L/300 K)(450 K)
⇒ V2 = 0.75 L
Answer:
These two numbers are fixed for an element. The mass number tells us the number the sum of nucleons of protons and neutrons in the nucleus of an atom. The atomic number also known as the proton number is the number of protons found in the nucleus of an atom. ... The atomic number uniquely identifies a chemical element.
Explanation:
Isomer is defined as compounds with the same formula but different arrangement of atoms in its molecule and they differ in their properties. The <span>representation that can be used to show differences between isomers is the use of structural formula. It shows the arrangement of each atoms. It cant be molecular formula and 3D drawing because it does not show the arrangement of the atoms.</span><span>
