Answer:

Mass = 197.78 g

Explanation:

Given data:

Number of moles = 5.8 mol

Mass of H₂S = ?

Solution:

Formula:

Mass = number of moles × molar mass

molar mass of H₂S = 34.1 g/mol

by putting values,

Mass = 5.8 mol × 34.1 g/mol

Mass = 197.78 g

Thus, 5.8 moles of H₂S have 197.78 g mass.

Answer:

We could make the surface tension to decrease by removing and causing a disruption to the intermolecular forces(hydrogen bonds).

Explanation:

To explain this answer, we will consider an experiment whereby a paper clip is made to rest at the top surface of water inside a container/beaker.

First of all, the intermolecular forces present in water are also known as hydrogen bonds.

It's relationship with surface tension is that when there is high surface tension in the water, this high tension will allow the paper clip to rest on top of the hydrogen bonds present at the top surface in between the water molecules.

However, the surface tension will decrease when we remove or cause a disruption to the intermolecular forces (hydrogen bonds).

Answer:

I think that the answer is B or a

Explanation:

Answer:

10.63 × 10^(-24) g

10.62 × 10^(-27) kg

64 daltons

Explanation:

Formula for sulfur (IV) oxide is; SO2

Now,

Atomic mass of Sulphur is 32 while atomic mass of oxygen is 16.

Thus;atomic mass of SO2 is;

32 + (16 × 2) = 64 amu

Now,

1 mole of a substance has 6.02 × 10^(24) molecules

Therefore mass of 1 molecule of SO2 will yield;

Mass(g) = 64/(6.02 × 10^(24)) = 10.63 × 10^(-24) g

Converting to kg, we have;

10.63 × 10^(-24) ÷ 1000 = 10.62 × 10^(-27) kg

Now, converting to Dalton, we know that;

1kg = 6.022 × 10^(26) amu

Thus; 10.62 × 10^(-27) kg will yield;

(10.62 × 10^(-27) × 6.022 × 10^(26))/1 ≈ 64 amu

Now, from conversion;

1 amu = 1 Dalton.

Thus, 64 amu = 64 daltons

Answer:

b for sure

Explanation:

The specific heat capacity of the metal : c = 2.59  J/g °C

Given

5 g sample

35 ml water = 35 g

Required

The specific heat capacity of the metal

Solution

Heat can be formulated :

Q = m.c.Δt

Q in = Q out

Q absorbed = Q released

Q water = Q metal

35 g x 4.184 J/g °C x (26.5-20)= 5 x c x (100-26.5)

951.86 J = 367.5 x c

c = 2.59  J/g °C

Answer:

4.2 × 10¹⁷ atoms of Se

Explanation:

Step 1: Convert the mass to grams

We will use the conversion factor 1 g = 10⁶ μg.

55 μg × 1 g/10⁶ μg = 5.5 × 10⁻⁵ g

Step 2: Calculate the moles corresponding to 5.5 × 10⁻⁵ g of Se

The molar mass of Se is 78.96 g/mol.

5.5 × 10⁻⁵ g × 1 mol/78.96 g = 7.0 × 10⁻⁷ mol

Step 3: Calculate the atoms in 7.0 × 10⁻⁷ moles of Se

We will use Avogadro's number: there are 6.02 × 10²³ atoms of Se in 1 mole of Se.

7.0 × 10⁻⁷ mol × 6.02 × 10²³ atom/1 mol = 4.2 × 10¹⁷ atom

Explanation:

Answer :Nonliving and living things can be made up of combined elements

Explanation:

Answer:

26.2g = Mass of water in the calorimeter

Explanation:

The heat absorbed for the water is equal to the heat released for the metal. Based on the equation:

Q = m*C*ΔT

Where Q is heat, m is the mass of the sample, C is specific heat of the material and ΔT is change in temperature

Replacing we can write:

[tex]m_{metal}*C_{metal}*dT_{metal}=m_{water}*C_{water}*dT_{water}[/tex]

13.9g * 0.449J/g°C * (54.2°C-15.6°C) = m(H₂O) * 4.184J/g°C * (15.6°C-13.4°C)

240.9J = m(H₂O) * 9.2J/g

Answer:

Steel is less malleable.

Explanation:

Steel is less malleable than the elements that make it because of the presence of carbon in it. Steel is an alloy of iron and carbon which is harder than iron because of the presence of carbon. Iron in its pure form is softer that able the atoms slip over one another. If carbon is added, they stop the iron atoms from sliding apart so easily. This makes the metal stronger and harder.

Answer:

How do ion charges differ for the fourth main group column and the transition metals? Do not have common charges. Transition metals tend to form positive ions, but the number of electrons that are lost varies. Describe how atoms with a large difference in electronegativity form ionic bonds.

Explanation: ?

Answer: true

Explanation:

B. A scientific theory and a societal law

Newton's law states that:

Newton could not explain:

Thus, correct option is B i.e. the difference between a scientific and societal law.

Answer:

Structural formula

Explanation:

Various type of formulae describe an organic compound. The empirical formula only shows the ratio of atoms of each element present. The molecular formula shows the exact number of atoms of each element present.

Lastly, the structural formula shows us the arrangement of these atoms in space. It shows us the number of atoms, nature and bond types in organic compounds​.

The structural formula enables us to picture what the real molecule must look like.

Answer:

net force

Explanation:

Answer:

Second option - The bond is very polar

Explanation:

Electronegativity of an basically refers to the degree at which an electron is able to attract electrons to itself.

There are different types of bonds between atoms, depending on the electronegativity of the atoms.

When there is a large difference in electronegativity, it pretty much means that one atom would draw electrons more than the other. When this happens, the bond is said to be polar because there is uneven distribution of the charges.

The second option is the correct answer in thus question.
