is muriatic acid a compound or not?

Answers

Answer 1
Hydrochloric acid is a mixture. Although we use HCl as the formula for hydrochloric acid, HCl is, in fact, the formula of hydrogen chloride, which is a compound. Hydrogen chloride is a gas which readily reacts with water.

HCl + H2O ———-> H3O^+(aq) and Cl^-(aq)

Hydrochloric acid is a mixture of these ions

H2O and H3O^+(aq) and Cl^-(aq)

There are many different concentrations of hydrochloric acid - it must be a mixture.

What is the mass, in grams, of 0.450 moles of Sb?

Answers

Answer:

54.9 g

Explanation:

0.450 mol x 122g/mol

Relative and average atomic mass both describe properties of an element related to its different isotopes. Out of these two Relative atomic mas is more accurate. Therefore, 54.9 g is the mass in grams of 0.450 moles of Sb.

What is mass?

Mass defines the quantity of a substance. It is measured in gram or kilogram. Average mass is the mass of atoms of an element that are isotopes. It can be calculated by multiplying mass of a isotope to natural abundance of that isotope.

Average atomic mass = (mass of first isotope× percent abundance of first isotope)+(mass of second isotope× percent abundance of second isotope)

Mass of  Sb= number of moles of  Sb ×Molar mass of  Sb

=0.450 mol x 122g/mol

=54.9 g

Therefore, 54.9 g  is the mass in grams of 0.450 moles of Sb.

Calculate the heat that must be supplied to
a 532 , stainless steel vessel containing 375 g
of water to raise its temperature from 35 C
to the boiling point of water 100°C. Cs. =0.51 J/g. degrees C
Answer in units of J.

Answers

Q must be supplied = 119523.3~J

Further explanation  

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 = Q out  

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  

So from the question :

Q to the system(Q supplied) = Q water + Q steel vessel(Q gained)

[tex]\tt Q~supplied=m.c\Delta T(water)+m.c\Delta T(vessel)\\\\Q~supplied=375\times 4.18\times (100-35)+532\times 0.51(100-35)\\\\Q~supplied=101887.5+17635.8=119523.3~J[/tex]

Answers

Answer:

At the end of meiosis, there are four cells, each with 23 chromosomes, for a total of 92 chromosomes split between the four cells.

Explanation:

During meiosis, a diploid cell  (46 chromosomes) replicates its DNA (making 92 chromosomes) then undergoes two cell divisions to generate four haploid cells (23 chromosomes).

These haploid cells are the gametes which, during fertilization, fuse to become a zygote with 46 chromosomes.

Describe what will happen to the pressure of the gas as the plunger is pushed in.

Answers

Answer:

The pressure of gas will increase.

Explanation:

The question above is related to "Boyle's Law." According to this law, provided that the temperature and amount of gas are stable, the absolute pressure of gas is inversely proportional to its volume.

In this sense, if the plunger will be pushed in, the volume of the gas will definitely decrease due to lack of space while the pressure will increase because the molecules of the gas are colliding with each other. The greater the collision, the greater the pressure. This explains the answer above.

Gains energy by eating other living things

The statement 'gains energy by eating other living things' is a characteristic shared by both primary and secondary consumers (Option D).

Producers (e.g. algae and plants) are autotrophic organisms that generate their own food.

Primary consumers and secondary consumers are heterotrophs that need to eat other organisms to survive.

Primary consumers can be, for example, herbivores, whereas secondary consumers can be carnivores.

The bright red line from the emission spectrum of hydrogen has a wavelength of 657 nm. What is the energy, in joules, of a single photon of this light? 4.35 x 10–40 J 3.03 x 10–28 J 3.03 x 10–19 J 4.56 x 1014 J

Answers

Answer:

3.03 × 10^-19 J

Explanation:

The energy, E, of a photon of light can be calculated by using the formula:

E = hv

Where; E is energy in Joules,

h is Planck's constant {6.626×10^−34J}

v is frequency of light

For this question, the wavelength (λ) is given, not the frequency (v).

Hence, we use;

v= c/λ

Where v= frequency, c= speed of light (3×10^8m/s), λ= wavelength (657nm)

657nm = 657 × 10^-9m

v = 3×10^8/657 × 10^-9

v = 3/657 × 10^(8--9)

v = 0.00456 × 10^17

v = 4.56 × 10^14

Since frequency (v) = 4.56 × 10^14;

E = hv

E = 6.626×10^−34 × 4.56 × 10^14

E = 30.21 × 10^(-34+14)

E = 30.21 × 10^-20

E = 3.021 × 10^-19

Therefore, the energy of the photon of light is 3.02 × 10^-19 J

What mass does 4.41 moles of cobalt have? Help!!!!

Answers

Answer:

260 g

Explanation:

Data obtained from the question include:

Mole of cobalt (Co) = 4.41 moles

Mass of cobalt (Co) =...?

The mole of a substance is related to its mass according to the following equation:

Mole = mass / Molar mass.

With the above formula, we can obtain the mass of 4.41 moles of cobalt as follow:

Mole of cobalt (Co) = 4.41 moles

Molar mass of cobalt = 59 g/mol

Mass of cobalt (Co) =...?

Mole = mass /Molar

4.41 = mass / 59

Cross multiply

Mass of cobalt = 4.41 × 59

Mass of cobalt = 260 g

Therefore, the mass of 4.41 moles of cobalt is 260 g

Which of the following is used for chemical symbols today? a. drawings c. letters b. icons d. numbers

Answers

Answer:

Letters

Explanation:

For example, today we use the periodic table which is full of elements named with 1 or 2 letters. Like how Helium is He and Sodium is Na. Hope this helps!!!

Chemical symbols are used to identify an element and it is represented by one or two letters from their latin name. Thus option c is correct.

What is chemical symbol?

Chemical symbols are representations for elements and compounds. Each element in the periodic table have their own symbol which first letter or first two letters from their latin name.

For example, hydrogen has the symbol H, oxygen is O, N for nitrogen C for carbon, Na for sodium etc. The latin name of sodium is natrium, that's why it has the symbol Na.

The letters used in the chemical symbol must be capital. If two letters are there like in Na, Ar etc. the first letter be capital and second letter have to be in small case.

In a similar way compounds can be represented using chemical symbols with number of each atom given as subscripts of the elemental symbol as in CO₂, H₂O etc.

Van der Waals forces exist among all kinds of atoms and molecules. The origin of this  force stems from the instantaneous dipole-induced dipole interactions among adjacent polar atoms and molecules.

Among polar molecules, there are three components that contribute to the total  forces: the induction force, the orientation force and the dispersion force.

The  Van Der Waal forces that act between macroscopic bodies and surfaces in a solvent medium are relevant to the phenomena of protein adsorption.
