you have to show us the rest of it because we have no idea what your looking at. I'm sorry
The answer is Three
!!!!!!
We know that [OH⁻] * [H⁺] = 10⁻¹⁴
plugging the value of [H⁺]
[OH⁻] * 1.2 * 10⁻³ = 10⁻¹⁴
[OH⁻] = 10⁻¹⁴ * (10³/1.2)
[OH⁻] = 833.3 * 10⁻¹⁴
[OH⁻] = 8.33 * 10⁻¹²
I don't know if this will help but here are some chemical properties of acids and bases :
taste: sour (vinegar)
base: bitter (baking soda)
smell: frequently burns nose
base: usually no smell (except NH3)
texture: sticky
base: slippery
reactivity: frequently react with metals to form H2
base: react with many oils and fats
For a given peak intensity of radiation of a star that occurs at a wavelength of 2 nanometers, this is located at the spectral band of an X-ray. An X-ray's wavelength typically goes from 0.1 nano meters to 10 nano meters. Given that, the wavelength of the star fits perfectly into the range of an X-ray
