Mercury has a specific gravity of 13.6. how many milliliters of mercury have a mass of 0.35 kg
SashulF [63]

The formula for specific gravity is:

Specific gravity = \frac{\rho _{substance}}{\rho _{water}}

where \rho _{substance} is the density of the substance and \rho _{water} is the density of water.

The density of water, \rho _{water} = 1 g/mL

Substituting the values in above formula we get,

13.6 = \frac{\rho _{substance}}{1}

\rho _{substance} = 13.6 g/mL

The formula of density is:

density = \frac{mass}{volume}

The density of mercury is 13.6 g/mL

The mass of mercury is 0.35 kg = 0.35 kg \times 1000 \frac{g}{kg} = 350 g

Substituting the values in density formula:

13.6 g/mL = \frac{350 g}{volume}

volume = \frac{350 g}{13.6 g/mL} = 25.73 mL

Why does a salt compound give off light (or a colored flame) when burned? 4. did lithium chloride and sodium chloride give off s
Free_Kalibri [48]

3) Answer is: because elements have different emmision spectrum.

Emission spectrum of a chemical element is the spectrum of frequencies emitted due to an atom making a transition from a high energy state to a lower energy state. Each element's emission spectrum is unique.

4) Answer is: lithium chloride and sodium chloride do not have similar colors.

Lithium ion has red and sodium ion has yellow emission spectrum.

5) Answer is: because metals have valence electrons in different energy shells.

Each transition has a specific energy difference.

6) Answer is: salts of alkaline and earth alkaline metals.

For example barium chloride gives green light.

If an atom of the following element had a neutral charge, how many electrons would it have?
Yakvenalex [24]

Answer:

31

Explanation:

In order for an atom to have a neutral charge, it needs to have the same number of protons and electrons. You can see by the illustration that the atomic number is 31, so this element has 31 protons. Knowing that, we also know that it must have 31 electrons to be neutral.
