Answer:

Formula of magnesium oxide is MgO and formula of strontium oxide is SrO

Explanation:

Ca, Mg and Sr are same group bivalent metals.

Oxygen is a bivalent element

In general, formula of a compound made of a cation $M^{x+}$ and an anion $A^{y-}$ is $M_{y}A_{x}$ for $x\neq y$

When x = y, formula of the compound becomes MA

As both these metals and oxygen are bivalent therefore formula of magnesium oxide is MgO and formula of strontium oxide is SrO.

The four lines observed in the visible emission spectrum of hydrogen tell us that: a. We could observe more lines if we had a st

Aliun [14]

Answer:

c. Only certain energies are allowed for the electron in a hydrogen atom

Explanation:

Emission spectrum are produced when the excited electron in a atom release the energy in the form of photons to come to ground state. These photons are of different wavelengths depending on the excitation state of emitting electron or transition of electron. These electromagnetic radiation are observed through prism to produce the spectrum.

As the name indicates this spectrum is produced by emission of energy. Although the electron can be excited by different methods such as by heating but the key point is that electrons in hydrogen atom will emit the photons of same energy which they absorb and each electron can absorb only certain type of energy. So four lines were observed in the visible spectrum of hydrogen because only certain energies are observed for hydrogen atom.

A 32.8 g sample of gas occupies 22.414 L at STP. What is the molecular weight of this gas?

olasank [31]

Answer:

32.8g/mole

Explanation:

Given parameters:

Mass of sample of gas = 32.8g

Volume = 22.4L

Unknown:

Molecular weight = ?

Solution:

To solve this problem we must understand that at rtp;

1 mole of gas occupies a volume of 22.4L

Number of mole of the gas = 1 mole

Now;

Mass = number of moles x molecular weight

molecular weight = $\frac{mass}{molecular weight}$ = $\frac{32.8g}{1mole }$ = 32.8g/mole
