Answer:
Charge is caused by a flow of electrons, since electrons are around the nucleus they can be lost or gained by atoms. When an atom gets charged, it gains a charge, that is, it gains an electron. Since electrons are negatively charged, when an atom gains one, it also becomes negatively charged.
Answer:
The common oxide of nitrogen that has a positive ΔS°f is nitric oxide (NO)
Explanation:
Without reference to thermodynamic data, we have;
1) N₂ (g) + O₂ (g) ⇄ 2 NO (g)
1 unit of N₂ + 1 unit of O₂ (total of 2 units) gives 2 units of NO, (Increase of +0 disorder)
∴ΔS°f = +ve
2) 2NO + O₂ → 2NO₂
2 unit of NO + 1 unit of O₂ (total of 3 units) gives 2 units of NO₂, (Decrease of disorder)
∴ΔS°f = -ve
3) N₂ + 1/2 O₂ → N₂O
1 unit of N₂ + 1/2 unit of O₂ (total of 1+1/2 units) gives 2 units of NO₂, (Decrease of disorder)
∴ΔS°f = -ve
4) 4 NO₂ + O₂ → 2N₂O₅
4 unit of NO₂ + 1 unit of O₂ (total of 5 units) gives 2 units of N₂O₅, (Decrease of disorder)
∴ΔS°f = -ve
5) NO + NO₂ ⇄ N₂O₃
1 unit of NO + 1 unit of NO₂ (total of 2 units) gives 1 unit of N₂O₃, (Decrease of disorder)
∴ΔS°f = -ve
Therefore, the common oxide of nitrogen that has a positive ΔS°f without reference to thermodynamic data is nitric oxide NO.
Parents can influence adaptations to their offspring(s) by inherited traits. Inherited traits may include traits like running fast and/or hopping higher just because of their parents traits some offspring may end up having the same traits which can help them survive in their habitat environment.
Parents can also influence adaptations in their offspring(s) by learned activity from their parents. Learned traits from the parent(s) is an activity a parent teaches their offspring. For example, if their parent teaches their offspring how to hunt, it makes the offspring survive in their habitat environment.
Parents also can influence adaptations in their offspring(s) by instinctive traits. Instinctive traits are traits that are unlearned from the parent, the offspring learns from instinct. For instance, an instinctive trait can be social behaviors in pack animals. They don't need to learn they already have it in them genetically. And with instinctive traits they can adapt and survive.
