The format of any single replacement reaction can be written as

XY + Z —> ZY + X

You have a lone ion and (typically) an ionic compound. The lone ion will switch with a part of the ionic compound.

For example:

NaBr + Li —> LiBr + Na

You can see that the Lithium and Sodium switch places.

It might help to just remove the coefficients from the equations to just look at the interaction of the species.

Hint: there are two in the list that you provided

Hope this helps

Answer:

- $SnO_2+2H_2-->Sn+2H_2O$

- $2Al+6HCl-->2AlCl_3+3H_2$

Explanation:

Hello,

Single displacement reactions happen when one compound reacts with a single element or molecule to yield one compound and a single element or molecule as well by exchanging the cation or the anion depending on the case, in such a way, the reactions that accomplish the definitions are:

- $SnO_2+2H_2-->Sn+2H_2O$

- $2Al+6HCl-->2AlCl_3+3H_2$

Best regards.

How do Nitrate levels vary between tap water bottled water distilled water and outdoor water?

Ganezh [65]

The key difference between tap water and distilled water is that tap water may contain impurities whereas distilled water does not contain impurities. Water covers more than 70% of the earth' surface. Thus, there is less than 1% of water left for direct human use.

Identify the spectator ions in the following molecular equation.

SOVA2 [1]

We can rewrite the equation KBr(aq) + AgNO3(aq) → AgBr(s) + KNO3(aq) into its net ionic equation into
K+ + Br- + Ag + + NO3- = AgBr + K + NO3-only aqueous solutions can dissociate. Spectator ions are present in both sides, hence these are K+ and NO3-. THe rules of assigning oxidation numbers is to identify the number of valence electrons of elements and may be arbitrary depending on the charge of the molecule.

What Size container do you need to hold 0.0459 mol of N2 gas at stp

Allushta [10]

Hello!

You need to calculate the volume of the container. To calculate the volume of this amount of N₂ gas we need to make the assumption that N₂ behaves like an ideal gas.

1 mole of an ideal gas under Standard Temperature and Pressure occupies 22,4 L so the calculations are as follows:

$0,0459 mol N_2* \frac{22,4 L}{1 mol N_2}= 1,028 L$

So, the volume of the container should be 1,028 L or more.

Have a nice day!
