Yes it is h20 is a strong base
Answer: On Earth, liquid water exists on the surface in the form of oceans, lakes and rivers. It also exists below ground as groundwater, in wells and aquifers. Water vapor is most visible as clouds and fog. The frozen part of Earth's hydrosphere is made of ice: glaciers, ice caps and icebergs.
Answer: Nitrogen
Explanation: materials with high amounts of carbon are considered brown materials so materials with high amounts of nitrogen are considered green
CO will diffuse faster than CO2 because its molar mass is smaller.
The rate of diffusion depends on molecular weight and the least mass will diffuse faster.
The nucleus of the atom is the heaviest part of the atom.
- The nucleus consists of neutrons and protons
- Both neutrons and protons have masses, but only protons have charges
- The nucleus contains all the positive charges of an atom
- The mass of an atom is the sum of the numbers of protons and neutrons in a nucleus
When the ratio of neutrons to protons is too high, the nucleus becomes unstable and Beta emission has to take place.
- In beta emission, an extra neutron gives rise to a proton and an electron
- The electron is ejected from the nucleus
