Answer:
the nucleus is the center part of an atom
Explanation:
Answer:
Ionic equation:
Na⁺(aq) + OH⁻(aq) + H⁺(aq) + Cl⁻(aq) → H₂O(l) + Na⁺(aq) + Cl⁻ (aq)
Explanation:
Chemical equation:
NaOH(aq) + HCl(aq) → H₂O(l) + NaCl (aq)
Balanced chemical equation:
NaOH(aq) + HCl(aq) → H₂O(l) + NaCl (aq)
Ionic equation:
Na⁺(aq) + OH⁻(aq) + H⁺(aq) + Cl⁻(aq) → H₂O(l) + Na⁺(aq) + Cl⁻ (aq)
Net ionic equation:
OH⁻(aq) + H⁺(aq) → H₂O(l)
The Cl⁻(aq) and Na⁺ (aq) are spectator ions that's why these are not written in net ionic equation. The water can not be splitted into ions because it is present in liquid form.
Spectator ions:
These ions are same in both side of chemical reaction. These ions are cancel out. Their presence can not effect the equilibrium of reaction that's why these ions are omitted in net ionic equation.
Effusion is the process of a gas being poured out through a hole diametrically smaller than the structural exit of the container.
A lighter gas effuses faster than a heavier gas.
Thus gas A has a lower density and effuses slower than Gas B.
The substance should be in liquid state.
First, it takes up space in the container, which leads to that it shouldn't be a solid, because solid doesn't change its shape easily.
Second, it has a fixed volume, it's difficult to compress the substance, therefore it shouldn't be gas too, as gas can be compressed easily.
Therefore we're left with liquid. And both of these given properties fits the property of liquid.
Answer:
An ionic bond is that in which an electron is trasferred to another atom. Atoms that are considered metals have a low electronegativity meaning they are less likely to gain any electrons. Atoms that are non-metals have a higher electronegativity and are more likey to gain electrons than lose electrons. When an electron is either lost or gained by another electron the atome becomes more stable. Atoms with a complete and balanced valence shell stay close together because of the Nucleus with its strong electromagnetic pull. The stronger the pull the more likely the atom will gain an electron. The weaker the pull the more likely it will lose an electron.
