The mass of a solid substance is 21.1164 g. If the volume of

GuDViN [60]

Answer:

The density of the substance is 1.0611 $\frac{g}{cm^{3} }$

Explanation:

The density of a substance is a characteristic property that matter, whether solids, liquids or gases, has to be compressed in a given space, that is, it allows us to measure the amount of mass in a certain volume of a substance.

Density is expressed as follows:

$density=\frac{mass}{volume}$

In this case:

density: ?
mass: 21.1164 grams
volume: 19.9 cm³

Replacing:

$density=\frac{21.1164 grams}{19.9 cm^{3} }$

density= 1.0611 $\frac{g}{cm^{3} }$

The density of the substance is 1.0611 $\frac{g}{cm^{3} }$

How do the key results indicate

Lena [83]

The key results explain how you'll achieve a certain goal. They have to be quantitative, but always measurable in terms of their progress. This has to be considered when it comes to key results, because only results count for each milestone on the way to achieving the goal in question.

1. How many covalent bonds are expected to form from phosphorus in order to obey the octet rule?

Grace [21]

To satisfy the octet rule, there has to be eight electrons in phosphorus's outermost shell. Phosphorus has five electrons in its valence shell, fluorine has seven. This means that phosphorus would have to bond to three fluorine atoms in order to have eight electrons in its valence shell without breaking the octet rule in any one of the fluorine atoms.

What is the excess reactant for the following reaction given we have 3.4 moles of Ca(NO3)2 and 2.4 moles of Li3PO4? Reaction: 3C

Yuki888 [10]

Answer: The excess reactant for the given reaction is $Li_3PO_4$

Explanation:

Limiting reagent is defined as the reagent which is present in less amount and it limits the formation of products.

Excess reagent is defined as the reagent which is present in large amount.

For the given chemical reaction:

$3Ca(NO_3)_2+2Li_3PO_4\rightarrow 6LiNO_3+Ca_3(PO_4)_2$

We are given:

Moles of calcium nitrate = 3.4 mol

Moles of lithium phosphate = 2.4 mol

By stoichiometry of the reaction:

3 moles of calcium nitrate reacts with 2 moles of lithium phosphate

So, 3.4 moles of calcium nitrate will react with = $\frac{2}{3}\times 3.4=2.27mol$ of lithium phosphate

As, the given amount of lithium phosphate is more than the required amount. So, it is considered as an excess reagent.

Thus, calcium nitrate is considered as the limiting reagent because it limits the formation of products.

Hence, the excess reactant for the given reaction is $Li_3PO_4$
