Protons and neutrons are both inside the nuclei of the atom while the electrons are spinning around. they also make up the mass of the atom.
protons are positively charged while neutrons are neutral.
Protons and electrons are alike in the number while they are opposites in the charge because protons are positive while electrons are negative. Their quantity makes up the atomic number for an element.
Abundant hydrogen high temperature high pressure is that they need
When ignited, the gas mixture converts to water vapor and releases energy, which sustains the reaction: 241.8 kJ of energy (LHV) for every mole of H2 burned.” A mole of hydrogen weighs 2 grams. So, this is a LHV (lower heating value) of 120.9 kJ/gram of hydrogen when heat of vaporization is subtracted.
Answer:
Color, formation, gas, odor,
Explanation:
- change are a change in color
- formation of a precipitate
- formation of a gas
- odor change
- temperature change
ionic compound. The atom that lost the electron becomes a cation, and the atom that gains an electron becomes an anion. The cation and anion bond together because they have opposite charges to form an ionic compound. The question may be looking for just cation or anion, though.
