Answer:

hydrochloric acid

Explanation:

These anions usually have the ending “-ide.” As acids, these compounds are named starting with the prefix “hydro-,” then adding the first syllable of the anion, then the suffix “-ic.” For example, HCl, which is hydrogen and chlorine, is called hydrochloric acid. More complex acids have oxygen in the compound.

Just took the quiz

Answer:

151.1J

Explanation:

Given parameters:

Mass of iron  = 6.21g

Initial temperature of iron  = 25°C

Final temperature of iron  = 79.8°C

Unknown:

Amount of heat = ?

Solution:

The amount of heat require to cause this temperature can be determined using the expression below;

    H  = m c (T₂ - T₁)

H is the amount of heat

m is the mass

c is the specific heat capacity

T is the temperature

    Specific heat capacity of iron 0.444J/g°C

Insert the parameters and solve;

     H  = 6.21 x 0.444 x (79.8 - 25)

     H   = 151.1J

Answer:

Radiation ...........

[tex]\huge\boxed{Conduction}[/tex]

Conduction is the transfer of heat when two things come in contact with each other. The energy transfer is from hotter body to the colder body.

                                x---------------------------------------------x

There is a trick behind fire-walking. When the coal burns, after sometime there is a layer of ash on the surface of the coal which blocks the radiation. So the transfer of heat is not possible from radiation. Conduction is the only way possible. The person's feet and coal both are poor conductor of heat so if we walk quickly i.e. there is minimal time of contact with the coal, it will just feel a little warm. As the person start walking on the coal, It has to do it quickly, that way Person will feel its sole warming up but it is not that hot because of the layer of ash and poor conductance, after few steps the ash also sticks on to the sole of the person which makes kind of double layers of ash. So the only way for heat transfer is CONDUCTION.

Answer:  The temperature of a beaker of water is 318.2 K.

Explanation:

Multiplying the temperature in Celsius by tells us how many Fahrenheit degrees above the freezing .

Answer: The answer is biotic

Explanation:Mushrooms are biotic because they are living things. Abiotic means non living, so these are factors in the environment that influence a living thing's life and chance of survival

Answer: jdusjzj bacteria germs

Explanation:

Answer:

The water cycle or hydrologic is a continuous cycle where water evaporates, travels into the air and becomes part of a cloud, falls down to earth as precipitation, and then evaporates again. ... These areas are usually close to oceans or large bodies of water that allow more water to evaporate and form clouds.

Explanation:

Answer:

P = 34.1 L

Explanation:

Given data:

Number of moles = 10 mol

Volume occupy = 15 L

Temperature = 350°C

Pressure of gas = ?

Solution:

The given problem will be solve by using general gas equation,

PV = nRT

P= Pressure

V = volume

n = number of moles

R = general gas constant = 0.0821 atm.L/ mol.K  

T = temperature in kelvin

Now we will convert the temperature.

350+273 = 623 K

by putting values,

P×15 L = 10 mol ×0.0821 atm.L/ mol.K ×623 K

P = 511.48atm.L/15L

P = 34.1 L

1, 3, 1, 3

Explanation:

Ga - one on both sides

F - three on both sides

CN - three on both sides

K - three on both sides

But remember that CN was being multiplied by 3 on the right side already, meaning GA(CN)3 didn't mean a coefficient.

Answer:

Double re-placement

Answer:

Rutherfords

Explanation:

The model of the atom supported by Bohr's hydrogen experiment is the Rutherford's model of the atom.

Rutherford through his experiment on gold foil suggested the atomic model of the atom. The model posits that an atom has a small positively charged center(nucleus) where nearly all the mass is concentrated.

Answer:

  dissolved

Explanation:

The figure shows sodium chloride is in solution. It gets that way by being dissolved.

There are 20.8 moles of propanol

The mole is the number of particles(molecules, atoms, ions) contained in a substance  

1 mol = 6.02.10²³ particles

Can be formulated

N=n x No

N = number of particles

n = mol

No = Avogadro's = 6.02.10²³

1.2 x 10⁵ molecules of propanol

[tex]\tt \dfrac{1.25\times 10^{25}}{6.02\times 10^{23}}=20.8~moles[/tex]

It's called phototropism

Answer:

The answer is (Phototropism)

Answer:

It is the last one.

Explanation:

Water molecules are polar, they have cohesive properties, and water is less dense when it is solid than when it is a liquid, that is why ice floats in liquid water. However, water is a very good solvent, it can dissolve many solids, including sugar, salt, and other hydrophilic substances.

Explanation:

i think the answer is first and last

Answer:

D. Volume

Explanation:

Properties mentioned in the question;

colour = gray

Nonmetallic

Density = 3.8 g/mL

Volume = 48.3 mL

Of the mentioned, which is extensive ?

Extensive properties are those properties that are proportional to the amount of substance present.

The correct option is D. Volume. The other properties do not change with increasing or decreasing amount of the mineral

Answer:

0.36mol

Explanation:

Given parameters:

Volume of NaCl  = 0.4L

Molarity  = 0.9M

Unknown:

Number of moles  = ?

Solution:

To find the number of moles, the molarity of a solution is the amount of solute contained in a solution.

 Molarity  = [tex]\frac{number of moles}{volume}[/tex]  

 Number of moles = molarity x volume

 Insert the parameters and solve;

 Number of moles = 0.4 x 0.9  = 0.36mol
