You just need the number of protons and number of neutrons as the mass of eelctrons is negligible
The interaction between the two atoms of H in H2 with the lower energy corresponds to a covalent bond between hydrogen's.
When the two atoms of H form a bond, they are overlapping the individual orbitals to form a new one. Every hydrogen has 1 electron which sits in a 1s orbital and then form one molecular orbital. The energy of H2 is lower than individual hydrogens because the electrostatic interaction between them.
Answer:i don't rlly get the question but this is what i found on the internet :/
Explanation:
When the temperature is increased, the position of equilibrium moves in the endothermic direction to reduce the temperature. ... This means that as the temperature is increased, the position of equilibrium moves to the left, and the yield of ammonia decreases.
Answer:
Constant pressure of gas must have a constant volume and a constant number of moles of gas. It's equation is the ideal gas law: pV=nRT
Explanation:
The gas state is the most excited state. It doesn't have a definite volume or shape which is why it can be compressed. Gas pressure is basically the result of all the gas particles moving around and colliding against each other and their container. The rate this happens at as well as its force determines the pressure. Since there are many, many of these gas particles in all quantities of gas, the fluctuation of this rate as well as its intesity is nearly constant.
Answer: B. Chemists are constantly learning more about what makes chemicals dangerous.
Explanation: The safety of chemicals still remains of utmost importance as chemist haven't relented in their strive and curiousness at knowing the compounds, mixtures and elements which makes chemicals dangerous in other to minimize or mitigate the risk of exposure to this chemicals during usage. Chemicals are things we cannot do without as they constitute a lot to the human race in terms of Energy and health. Due to this immense contribution, the safety of chemicals will remain of great priority to chemists.
