18. Use the activity series to predict whether the following synthesis reaction will occur. Write the chemical equations for the

MAXImum [283]

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

<u>Explanation:</u>

Synthesis reaction is defined as a chemical reaction in which two small chemical substances combine together to form a single compound. The general equation for this chemical reaction follows:

$A+B\rightarrow AB$

For the reaction of calcium and oxygen combining together to form calcium oxide, the equation follows:

$2Ca(s)+O_2(g)\rightarrow 2CaO(s)$

By Stoichiometry,

2 moles of calcium element combines together with 1 mole of oxygen gas to produce 2 moles of calcium oxide.

Hence, the chemical equation for the reaction is given above.

A spectral line has a wavelength of 7.35 *10-7 m. What is the energy of this radiation?

antoniya [11.8K]

Answer:

2.7 x 10^-19 J

Explanation:

The formula needed for this problem is

E = hν

where E = energy, h = Planck's constant = 6.626x10^-34 and ν is the frequency

c = λν

where c = speed of light = 3x10^8, and λ = wavelength

3x10^8 = 7.35x10^-7 . ν

ν = 4.08 x 10^14 Hz

E = 6.626x10^-34 . 4.08x10^14 = 2.7 x 10^-19 J
