In some aquatic ecosystems, nitrate (no3–) is converted to nitrite (no2–), which then decomposes to nitrogen and water. as an example of this second reaction, consider the decomposition of ammonium nitrite: what would be the change in pressure in a sealed 10.0 l vessel due to the formation of n2 gas when the ammonium nitrite in 2.20 l of 1.10 m nh4no2 decomposes at 25.0°c?

Describe the particles of all three phases of matter in the root beer float. (how are the particles arranged and moving? )

An atomic nucleus is composed ofa)protons.b)protons and neutrons.c)protons and electrons.d)protons, neutrons, and electrons.

Imagine if during the cathode ray experiment, the size of the particles of the ray was the same as the size of the atom forming the cathode. which other model or scientific observation would have also been supported? 1. this would support dalton's postulates that proposed the atoms are indivisible because no small particles are involved. 2. this would support bohr's prediction about electrons moving in orbits having specific energy. 3. this would support bohr's prediction about electrons being randomly scattered around the nucleus in the atom. 4. this would support dalton's postulates that proposed that atoms combine in fixed whole number ratios to form compounds.
