Chemistry is the scientific discipline involved with elements and compounds composed of atoms, molecules and ions: their composition, structure, properties, behavior and the changes they undergo during a reaction with other substances.

n the scope of its subject, chemistry occupies an intermediate position between physics and biology.[5] It is sometimes called the central science because it provides a foundation for understanding both basic and applied scientific disciplines at a fundamental level.[6] For example, chemistry explains aspects of plant chemistry (botany), the formation of igneous rocks (geology), how atmospheric ozone is formed and how environmental pollutants are degraded (ecology), the properties of the soil on the moon (cosmochemistry), how medications work (pharmacology), and how to collect DNA evidence at a crime scene (forensics).

Chemistry addresses topics such as how atoms and molecules interact via chemical bonds to form new chemical compounds. There are two types of chemical bonds: 1. Primary Chemical bonds e.g covalent bonds, in which atoms share one or more electron(s); ionic bonds, in which an atom donates one or more electrons to another atom to produce ions (cations and anions); Metallic bonds and 2. Secondary chemical bonds e.g. hydrogen bonds;Van der Waals force bonds, ion-ion interaction, ion-dipole interaction etc.

Answer:

The specific heat capacity of this material is approximately [tex]1.6\; \rm J\cdot g^{-1} \cdot {\left(^\circ C\right)}^{-1}[/tex].

(Assume that there is no energy loss. Assume that the specific heat capacity of water is [tex]4.182\; \rm J \cdot g^{-1} \cdot {\left(^\circ C\right)}^{-1}[/tex].)

Explanation:

Let [tex]c[/tex] denote the specific heat capacity of a material. Consider a sample of that material with mass [tex]m[/tex]. If the temperature of that objects changes by [tex]\Delta T[/tex], the corresponding energy change would be [tex]Q =c \cdot m \cdot \Delta T[/tex].

Start by finding the amount of energy that water has gained from the [tex]50\; \rm g[/tex] sample.

That [tex]500\; \rm g[/tex] of water would have gained:

[tex]\begin{aligned} & Q(\text{water}) \\ &= c(\text{water}) \cdot m(\text{water}) \cdot \Delta T (\text{water}) \\ &\approx 4.182\; \rm J \cdot g^{-1} \cdot \left(^\circ C\right)^{-1} \times 500\; \rm g \times 3\; \rm ^\circ C \\ &\approx 6.27\times 10^{3}\; \rm J \end{aligned}[/tex].

Assume that the [tex]50\; \rm g[/tex] sample and the [tex]500\; \rm g[/tex] of water were insulated from the surroundings. The energy that water gained would be exactly the same as the energy that the [tex]50\; \rm g\![/tex] sample had released through cooling.

In other words, the [tex]50\; \rm g[/tex] sample has released approximately [tex]6.27 \times 10^{3}\; \rm J[/tex] of energy as it is cooled from [tex]100\; \rm ^\circ C[/tex] to [tex]23\; \rm ^\circ C[/tex].

Rearrange the equation [tex]Q = c \cdot m \cdot \Delta T[/tex] to find an expression for specific heat capacity, [tex]c[/tex]:

[tex]\begin{aligned}c = \frac{Q}{m \cdot \Delta T}\end{aligned}[/tex].

Apply this expression to find the specific heat capacity of the sample:

[tex]\begin{aligned}c(\text{sample}) &= \frac{Q(\text{sample})}{m(\text{sample}) \cdot \Delta T(\text{sample})} \\ &\approx \frac{-6.27\times 10^{3}\; \rm J}{50\; \rm g \times \left(-77\; \rm ^\circ C\right)} \approx 1.6\; \rm J \cdot g^{-1} \cdot {\left(^\circ C\right)}^{-1}\end{aligned}[/tex].

The volume of 3.5g of hydrochloric acid that has a density of 1.49 g/mL is 2.35mL.

Density is a measure of the mass of matter contained by a unit volume. The density of a substance can be calculated by dividing the mass of the substance by its volume as follows:

Density = mass ÷ volume

According to this question, 3.5g of hydrochloric acid has a density of 1.49 g/mL. The volume contained in this mass of hydrochloric acid can be calculated as follows:

1.49g/mL = 3.5g ÷ V

V = 3.5 ÷ 1.49

V = 2.35mL

Therefore, the volume of 3.5g of hydrochloric acid that has a density of 1.49 g/mL is 2.35mL.

Explanation:

The temperature of the water and the chromium : 25.122 ° C  

The law of conservation of energy can be applied to heat changes, i.e. the heat received / absorbed is the same as the heat released  

Q in(gained) = Q out (lost)

Heat can be calculated using the formula:  

Q = mc∆T  

Q = heat, J  

m = mass, g  

c = specific heat, joules / g ° C  

∆T = temperature difference, ° C / K

Answer:

A

Explanation:

I believe the answer is A. An object is every color except the color we see, or the color that bounces off of said object. Therefore if a carpet is yellow, the carpet is every color but yellow. Yellow is the color that it rejects, bounces off of it, and the one we see.

To solve this we must be knowing each and every concept related to reflections. Therefore, a pair of jeans look blue because  it reflects blue light.

In physics, reflection usually described as a change in the orientation of a waveform at the interface of two distinct media, bouncing the waveform back onto the original medium.

The color we perceive is primarily determined by how things interact with lighting as well as finally reflect or transfer it to our eyes.

The force of attraction between these two ions at their equilibrium interionic separation is F = -1.10 x 10⁻⁸.

The force of attraction is when the atoms of two molecules attract one another.

To calculate the attraction (F), we will use Coulomb's Law:

F = k Q1Q2 / r2

where  

Q₁ and Q₂ are the fees on the ions,

r is that the distance between them, and

k = the Coulomb constant

Given the Q₁ = 2+

Q₂ = 1-

r₊ = 0.072 nm

r₋ = 0.133 nm

k = 8.988 × 10⁹ N· m²C⁻²

Q₁ = (+2) × 1.602 × 10⁻¹⁹ C

= +3.204 × 10⁻¹⁹ C

Q₂ = (-1) × 1.602 × 10⁻¹⁹ C

= -1.602 × 10⁻¹⁹ C

r = r₊ + r₋

0.072 nm + 0.133 nm = 0.205 nm

= 0.205 × 10⁻⁹ m

F = -1.10 x 10⁻⁸

c1 * v1 = c2 * v2

Where:

Information about the problem:

Applying the dissolution of concentrations formula and clearing the volume of the concentrated solution (v1) we get:
