Answer:

Sr(NO₃)₂(aq) + Na₂CO₃(aq) ⇒ SrCO₃(s) + 2 NaNO₃(aq)

Sr²⁺(aq) + 2 NO₃⁻(aq) + 2 Na⁺(aq) + CO₃²⁻(aq) ⇒ SrCO₃(s) + 2 Na⁺(aq) + 2 NO₃⁻(aq)

Sr²⁺(aq) + CO₃²⁻(aq) ⇒ SrCO₃(s)

Explanation:

Let's consider the molecular equation that occurs when aqueous solutions of strontium nitrate and sodium carbonate react. This is a double displacement reaction.

Sr(NO₃)₂(aq) + Na₂CO₃(aq) ⇒ SrCO₃(s) + 2 NaNO₃(aq)

The total ionic equation includes all the ions and the insoluble species.

Sr²⁺(aq) + 2 NO₃⁻(aq) + 2 Na⁺(aq) + CO₃²⁻(aq) ⇒ SrCO₃(s) + 2 Na⁺(aq) + 2 NO₃⁻(aq)

The net ionic equation includes only the ions that participate in the reaction and the molecular species.

Sr²⁺(aq) + CO₃²⁻(aq) ⇒ SrCO₃(s)

Which shows the lewis structure of water with the correct partial charges and nonbonding electrons?

Lina20 [59]

Your problem here is incomplete. Luckily, I found a similar problem with Lewis structures of choices to choose the answer from (shown in the attached picture). We know that the bond of water is H-O-H. According to octet rule, oxygen must have 8 electrons surrounding it. The two bonds with H accounts for 4. So, the other 4 occur as non-bonding electrons. The partial negative charge goes to oxygen because it is more electronegative than hydrogen. <em>Therefore, the answer is B.</em>

In the hydrogenation of double bonds, a catalyst is needed. in the last step, the reactants must escape from the surface into th

Viktor [21]

The step in which reactant escape from the surface into the gas phase is known as desorption

Desorption is a phenomenon whereby a substance is released from or through a surface. One substance is released from another either from the surface or through the surface. Desorption can occur when the system is in the state of sorption equilibrium between bulk (fluid) and adsorbing surface.( boundary separating two fluids)

Which factor explains why coal dust in an enclosed space is more explosive than coal dust blown outdoors into an open space ? A.

ZanzabumX [31]

The correct option is B.

Coal dust refers to the powered form of coal. Because of the high surface area of coal dust it is highly prone to dust explosion, which involves rapid combustion of fine particles that are suspended in the air; this usually occur in an enclosed place. Coal dust in an enclosed place is more explosive than coal dust that is blown outdoor in an open space because the coal dust in an enclosed place is more concentrated due to restricted space, thus it is more liable to explosion.
