Answer from: jacobhawkins112471

4.5 g/ml

Explanation:

Density is the ratio of the mass of the liquid to the volume of the liquid. The unit of mass, volume and density are g, ml and g/ml respectively.

Density is directly proportional to the mass of the substance and is inversely proportional to the volume.

Given,

Mass of the liquid = 585 g

Volume of the liquid = 130 ml

Density = $\frac{mass}{volume}$ = $\frac{585 g}{130 ml}$ = 4.5 g/ml

Answer from: 25cotahai

The density of the sample of liquid with a volume of 130 mL and mass 585 g is $\boxed{4.5\;{\text{g/mL}}}$

Further explanation:

The property is a unique feature of the substance that differentiates it from the other substances. It is classified into two types:

1. Intensive properties:

These are the properties that depend on the nature of the substance. These don't depend on the size of the system. Their values remain unaltered even if the system is further divided into a number of subsystems. Temperature, refractive index, concentration, pressure, and density are some of the examples of intensive properties.

2. Extensive properties:

These are the properties that depend on the amount of the substance. These are additive in nature when a single system is divided into many subsystems. Mass, energy, size, weight, and length are some of the examples of extensive properties.

Density is a characteristic property of the substance. It is defined as the mass per unit volume. It is generally represented by $\rho$ .

The formula to calculate the density of the liquid is,

${\mathbf{Density of liquid}}\left({\mathbf{\rho}}\right){\mathbf{=}}\frac{{{\mathbf{Mass of liquid}}\left({\mathbf{M}}\right)}}{{{\mathbf{Volume of liquid}}\left({\mathbf{V}}\right)}}$ …… (1)

The mass of liquid (M) is 585 g. The volume of liquid (V) is 130 mL.

Substitute 585 g for the mass of liquid and 130 mL for the volume of liquid in equation (1).

$\begin{gathered}{\text{Density of liquid}}\left(\rho\right)=\frac{{{\text{585 g}}}}{{{\text{130 mL}}}}\\=\boxed{4.5\;{\text{g/mL}}}\\\end{gathered}$

So the density of the liquid with a volume of 130 mL and mass 585 g is ${\mathbf{4}}{\mathbf{.5}}\;{\mathbf{g}}{\text{/}}{\mathbf{mL}}$ .

Answer from: Quest

answer: $2c_5h_5+1fe\rightarrow 1fe(c_5h_5)_2$

the reaction is type of combination reaction.

explanation:

$? c_5h_5+? fe\rightarrow ? fe(c_5h_5)_2$

on the product side, there are 2 molecules of $c_5h_5$ bonded to fe which means one atom of fe are combined two molecules of $c_5h_5$ . so, balanced chemical equation becomes :

$2c_5h_5+1fe\rightarrow 1fe(c_5h_5)_2$

this reaction follows the reaction type of combination reaction. a combination reaction is defined as chemical reaction in which reactants combines together to form a single product.

$a+b\rightarrow ab$

Answer from: Quest

the seeing the electronic configuration we can say that the element is fluorine.

fluorine is the most electronegative element in the periodic table.

but by only seeing the configuration we cannot say about its reactivity because we don't know if its configuration after excitation or by addition of electrons.

but if not then, it is the lightest halogen and exists as a highly toxic pale yellow diatomic gas at standard conditions. as the most electronegative element, it is extremely reactive: almost all other elements, including some noble gases, form compounds with fluorine.
