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.

Answer:

C: 4

Explanation:

In every single covalent bond, each atom shares one electron. 1 + 1 = 2. A double bond is just two bonds so, 2 x 2 = 4.

Answer:

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.

A line that is drawn vertically down the earth but is not parallel to the prime Meridian.

Explanation:

A line that is drawn vertically down the earth but is NOT parallel to the Prime Meridian, best describes the meridian of longitude.

Prime Meridian is an imaginary line which divides the earth into eastern and western hemispheres

Meridian of longitude is an imaginary semicircle that runs from north to south direction and joins the two poles. All meridians are of the same length and meet at the poles.

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.

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

To prepare a solution of  hcl(aq) with a volume of 675.0 ml and a concentration of 1.00 m from a concentrated solution of 11.5 m we need a volume of: 58.69 ml

To solve this problem, the formula and the procedure that we have to use is:

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:

c1 * v1 = c2 * v2

v1 = (c2 * v2)/ c1

v1 = (1.00 m * 675.0 ml)/ 11.5 m

v1 = 58.69 ml

The charge of phosphate : 3-

Oxidation is an increase in oxidation number, while reduction is a reduction in oxidation number.

The formula for determining Oxidation Numbers in general:

1. Single element atomic oxidation number = 0.

Group IA (Li, Na, K, Rb, Cs, and Fr): +1

Group IIA (Be, Mg, Ca, Sr and Ba): +2

Group IIIA(Al, B) : +3

H in compound = +1, except metal hydride compounds (Hydrogen which binds to groups IA or IIA) oxidation number H = -1, for example, LiH, MgH₂, etc.

2. Oxidation number O in compound = -2, except OF2 = + 2 and in peroxide (Na₂O₂, BaO₂) = -1 and superoxide, for example KO₂ = -1/2.

3 The oxidation number in an uncharged compound = 0,

Total oxidation number in ion = ion charge, Example NO₃⁻ = -1

Compound AlPO₄ :

The oxidation number in an uncharged compound = 0

Since the charge of Al as group 3A (or group 13) is +3, while the AlPO₄ compound is a polyatomic compound (consisting of polyatomic ions PO₄ and Al), the PO₄ charge:

charge Al + charge PO₄ = 0

+ 3 + charge PO₄ = 0

charge PO₄ = -3

Answer:

V₂ = 545.79 mL

Explanation:

Given data:

Initial volume = 1000 mL

Initial pressure = 1 atm

Initial temperature = 273 K

Final temperature = 298 K

Final volume = ?

Final pressure = 2 atm

Formula:  

P₁V₁/T₁ = P₂V₂/T₂  

P₁ = Initial pressure

V₁ = Initial volume

T₁ = Initial temperature

P₂ = Final pressure

V₂ = Final volume

T₂ = Final temperature

Solution:

V₂ = P₁V₁ T₂/ T₁ P₂  

V₂ = 1 atm × 1000 mL × 298 K / 273 K × 2 atm

V₂ = 298000 atm .mL. K / 546 K.atm

V₂ = 545.79 mL

There is only one change when transcribing from a DNA sequence to a RNA sequence.  

Explanation:

The change when transcribing is that instead of thymine (T) in a DNA sequence, you have Uracil (U) in a RNA sequence. The rest will stay the same. So, DNA has ATCG, whereas RNA has UACG. There should be NO thymine (T) in your RNA sequence–– it should only include the four of the following: UACG.

Based on the law of multiple proportions, there are 0.55 grams of hydrogen.

Law of multiple proportions or Dalton's Law said that the ratios of the masses of the second element which combine with a fixed mass of the first element will be ratios of small whole numbers.

In one molecule of the ammonia, there are three hydrogen atoms and one nitrogen atom

In a molecule of ammonia (NH3), proportion of the masses of nitrogen and hydrogen is:

m(N) : m(H) = 14 : (3·1) = 14 : 3

Mass of nitrogen is 2.58 grams

2.58 g : m(H) = 14 : 3

m(H) = 0.55 g; mass of hydrogen needed to react with nitrogen

Balanced chemical reaction: N₂ + 3H₂ ⇄ 2NH₃
