Solid calcium oxide reacts with sulfur trioxide gas to produce solid calcium sulfate

antiseptic1488 [7]

<u>Answer:</u> The chemical equation for the given reaction is given below.

<u>Explanation:</u>

When solid calcium oxide reacts with sulfur trioxide gas to produce solid calcium sulfate, the chemical equation follows:

$CaO(s)+SO_3(g)\rightarrow CaSO_4(s)$

This is the reaction when a metal oxide reacts with non-metal oxide to produce a salt.

By Stoichiometry of the reaction:

1 mole of solid calcium oxide reacts with 1 mole of sulfur trioxide gas to produce 1 mole of solid calcium sulfate.

Estimate your de Broglie wavelength when you are running. (For this problem use h = 10^−34 in SI units and 1 lb is equivalent to

AlekseyPX

Answer:

A. your running speed 1.5 m/s

B. your mass 70 kg

C. your de Broglie wavelength $6.32x10^{-36}$ m

Explanation:

Hello there!

In this case, since the equation for the calculation of the Broglie wavelength is:

$\lambda =\frac{h}{m*v}$

We can assume a running speed of about 1.5 m/s and a mass of 70 kg, so the resulting Broglie wavelength is:

$\lambda =\frac{6.626x10^{-34}kg\frac{m}{s} }{70kg*1.5\frac{m}{s} }\\\\\lambda =6.32x10^-36m$

Best regards!
