How many lone pairs are around the central atom in the Lewis formula for the

1 answer:

Butoxors [25]3 years ago

6 0

Answer:

Zero Lone Pairs

Explanation:

Hydrogen Sulfate is made from Sulfuric acid. It is an ion and contains a negative charge on one of its oxygen atoms. The central atom of this ion is sulfur atom.

The lewis structure of hydrogen sulfate is attached below. It can be seen from the structure that the sulfur is carrying no lone pair of electrons as that carried by oxygen atoms. The sulfur atom is making four single or multiple bonds with oxygen atoms. Also, the electron and molecular geometry around sulfur is Tetrahedral.

1) If calcium were to combine with the compound barium nitrate, which member of the barium nitrate would calcium replace?

snow_tiger [21]

Answer:

Calcium would displace barium.

Explanation:

Ba(NO₃)₂ + Ca --> Ca(NO₃)₂ + Ba

There are two types of compounds: molecular/covalent and ionic.

Molecular/covalent compounds are non-metal + non-metal.

Ionic compounds are metal + non-metal.

Looking at the periodic table, barium is a metal. Calcium is also a metal.

Checking a polyatomic ions chart would tell you NO₃⁻ is a non-metal because it has a negative charge.

Since there is no metal + metal compound, the calcium metal would displace barium. The compound remains ionic.

Radio waves travel at the speed of light which is 3.00 x 10^8. How many minutes does it take for a radio message to reach saturn

ryzh [129]

Answer:

43.89 min

Explanation:

Given that:-

The speed of light = $3.00\times 10^8\ m/s$

The distance = $7.9\times 10^8\ km$

The conversion of distance in km to distance into m is shown below as:-

1 km = 1000 m

So,

Distance = $7.9\times 10^8\times 1000\ m=7.9\times 10^{11}\ m$

The relation between speed distance and time is shown below as:-

$Speed=\frac{Distance}{Time}$

Thus,

$3.00\times 10^8=\frac{7.9\times 10^{11}}{Time}$

$300000000\times time=10^{11}\times \:7.9\ s$

Time = 2633.33 seconds

Also, 1 s = 1/60 min

So,

Time= $\frac{2633.33}{60}\ min=43.89\ min$
