Is oxidation number the same as ionic charge? The oxidation state of a pure element is always zero. The oxidation state for a pure ion is equivalent to its ionic charge. In general, hydrogen has an oxidation state of +1, while oxygen has an oxidation state of -2. The sum of the oxidation states for […]

What is the oxidation number of diatomic elements? All free, uncombined elements have an oxidation state of zero. This includes the seven diatomic elements (such as O2) and the other molecular elements (P4 and S8). Ozone (O3) also has an oxidation state of zero. Do diatomic molecules have oxidation numbers? A Li+1 (aq) free ion […]

How high or low a sound is depends on the frequency? How high or low a sound seems to a listener is its pitch. Pitch, in turn, depends on the frequency of sound waves. High-frequency sound waves produce high-pitched sounds, and low-frequency sound waves produce low-pitched sounds. Infrasound has wave frequencies too low for humans […]

What is the complementary strand of this sequence 5 Gattaca 3? For the sequence 5′-GATTACA-3′, the complementary DNA strand would be 3′-CTAATGT-5′. How do you do complementary base pairing? Chargaff’s rule, also known as the complementary base pairing rule, states that DNA base pairs are always adenine with thymine (A-T) and cytosine with guanine (C-G). […]

Which sentence describes a tropical rainforest? it is always wet. Tropical rainforests are rainforests that occur in areas of tropical rainforest climate, between 10 degrees north and south of the equator. In tropical rainforest there is no dry season, all months have an average precipitation of at least 60 mm. Which sentence describes a tropical […]

What increases the amount of light that bends as it passes through a lens? When a lens is created, there are two main factors in its design. The refractive index of the material, which is how much the material it’s made out of slows down the beam, and the angle of incidence. The greater the […]

What will be the image formed in a concave side of a spoon or mirror? On the other hand, the concave side of the spoon acts like a concave mirror. If the spoon is held at arm’s length, the object (you) is farther from the reflecting surface than the center of curvature. As a result, […]

What are carbon sinks and why are they important? Carbon sinks are natural or artificial deposits that absorb and store carbon from the atmosphere helping reduce the greenhouse effect. The main natural carbon sinks are plants, soil and the ocean. Why are carbon sinks so important? A carbon sink is anything that absorbs more carbon […]
