Answer:
H20
water (the chemical symbol, as used in non-specific contacts. 8 equals hydrogen equals oxygen and two elements in hydrogen therefore is known as H2O .
H202
hydrogen peroxide equals hydrogen peroxide is the chemical compound with formula h202. And it's your form, it is very pale blue liquid, slightly more vicious than water. It is used as an oxidizer, bleaching agent, and antiseptic .
Co=
carbon monoxide, carbon monoxide is colorless, odorless, and tasteless flammable gas that is slightly less dense than air. Formula equals Co
The answer is thank u for the points!
Answer:
Explanation:E=hc¯ν=hcλ [Where h = Planck's constant, c = velocity of electromagnetic radiation(light) and lambda = wavelength.] So, just substitute every needed value. =1.29077⋅10−18 Joules
It well be 9025 because it will dissolve in 0.8 hcl soluiton
The dark smooth areas on the surface of the moon is called Maria.
Maria is made up of solidified lava which is a result of volcanic activity on the moon.
When Galileo observed these smooth dark spots on the moon he called them 'mare' which is latin for 'sea'. And the plural form of mare is 'maria'. Unlike Galileo predictions, recent investigations confirm that maria are not oceans but solidified lava.
