Convert 32.56 km/hr into ft/hr
Gekata [30.6K]
Note that
1 m = 3.2808 ft

Therefore
1 km = 3280.8 ft
and
32.56 \,  \frac{km}{h} = (32.56 \,  \frac{km}{h})*(3280.8 \,  \frac{ft}{km}) =  1.0682 \, \times 10^{5} \, \frac{ft}{h}

Answer: 1.0682 x 10⁵ ft/hr

Answer : The formula unit of Sr & Cl is SrCl_2 and the formula unit of Al & S is Al_2S_3

Explanation :

Formula unit : it is defined as the lowest number ratio of ions of an elements in an ionic compound or covalent compound.

For the formula unit of Sr & Cl, two chloride ions(Cl^-) are needed to neutralize the one strontium ion(Sr^{2+}).

For the formula unit of Al & S, three sulfide ions(S^{2-}) are needed to neutralize the two aluminium ion(Al^{3+}).

The formula unit of SrCl_2 and Al_2S_3 are shown below.
