Answer:

110.22 g in 2.75 moles of calcium

Explanation:

to convert moles to grams

moles (g/mol)

2.75 mol Ca (40.08 (atomic weight) g Ca/1 mol Ca)= 110.22

Explanation:

The density of a substance can be found by using the formula

[tex]density = \frac{mass}{volume} \\ [/tex]

From the question

mass = 95g

volume = final volume of water - initial volume of water

volume = 63 - 30 = 33 mL

We have

[tex]density = \frac{95}{33} \\ = 2.87878787...[/tex]

We have the final answer as

The photo I attached should make more sense as an explanation.

When balancing equations, the first and most important step is to count the # of each type of element on each side.

In this problem there are 5: Ca, O, H, N, and S.

Once you do that you can begin balancing.

Here is the initial tally for the elements in this problem:

On the left.....

Ca - 1

N - 2

S - 1

O - 6

H - 10

On the right.....

Ca - 1

N - 1

S - 1

O - 5

H - 5

Looking at these values, we can see N, O, and H all need adjusting the right side. You should never start balancing with O or H unless they are the only elements that need adjusting. They usually balance out with the rest of your work or with water in the end.

So given all of that, you should start balancing with N on the right. Giving NH3 a coefficient of 2 will change the number of Nitrogen atoms on the right to 2. Be careful though! It will also change the number of Hydrogen atoms from 5 to 8 (because (2*3) =6 and 6+2 =8).

Let's tally our numbers again.

On the left..... (these should be unchanged)

Ca - 1

N - 2

S - 1

O - 6

H - 10

On the right.....

Ca - 1

N - 2

S - 1

O - 5

H - 8

Okay, now we see only O and H need adjusting on the right. Luckily there is H2O so we can do that without impacting the number of other atoms.

Give H2O a coefficient of 2 and count the number of atoms on the right again.

On the right.....

Ca - 1

N - 2

S - 1

O - 6 (because 4 from CaSO4 plus 2 from 2H2O = 6)

H - 10 (6 from NH3 plus 4 from 2H2O = 10)

Do these numbers match what you have on the the left side of the equation? Yes! It is balanced so you do not need to adjust anymore. Your coefficients in the answer will be 1-1-1-2-2.

Answer:

True

Explanation:

Answer:

A chemical formula is a way of presenting information about the chemical proportions of atoms that constitute a particular chemical compound or molecule, using chemical element symbols, numbers, and sometimes also other symbols, such as parentheses, dashes, brackets, commas and plus and minus signs. These are limited to a single typographic line of symbols, which may include subscripts and superscripts. A chemical formula is not a chemical name, and it contains no words. Although a chemical formula may imply certain simple chemical structures, it is not the same as a full chemical structural formula. Chemical formulae can fully specify the structure of only the simplest of molecules and chemical substances, and are generally more limited in power than are chemical names and structural formulae.

The outmost free electron which is present in the outer shell is called valency. The number of elements joining together to form the compound also depends on the valency.

Each electron has revolved around the nucleus and that path is considered as orbit. The orbit is as follows:-

The free electrons are usually lie in the outmost shell.

Hence according to the question, the correct option is S and P orbit.

Answer:

ceo que3

Explanation:

Answer

Calculating the mass number for an atom requires that we know the atomic number and the number of protons in the atom’s nucleus. The mass number then gives us the average weight of atoms of a given element. However, as long as the number of protons equals the number of neutrons, the values balance out and we always obtain a whole number for the mass number.

Answer:

Darmstadtium

Explanation:

An element with the electronic configuration 1s²2s²2p⁶3s²3p⁶4s²3d¹⁰4p⁶5s²4d¹⁰5p⁶6s²4f¹⁴5d¹⁰6p⁶7s²5f¹⁴6d⁸ has 110 electrons in its electron shells.

Since the element is a neutral atom, this number is also equal to its atomic number. Therefore, its atomic number is 110.

The element in the period table that has an atomic number of 110 is Darmstadtium, a d-block element, thus a transittion metal. It also belong to period 7 in the Periodic table of elements.

The element that has the electron configuration is Darmstadtium.

Since An element with the electronic configuration 1s²2s²2p⁶3s²3p⁶4s²3d¹⁰4p⁶5s²4d¹⁰5p⁶6s²4f¹⁴5d¹⁰6p⁶7s²5f¹⁴6d⁸ contains 110 electrons in its electron shells.

Also, the element should be a neutral atom, this number should also equal to its atomic number. Therefore, its atomic number is 110.

The element in the periodic table that has an atomic number of 110 is Darmstadtium, a d-block element, thus a transition metal.

Answer:

The force of attraction between oppositely charged particles is directly proportional to the product of the charges on the two objects (q1 and q2) and inversely proportional to the square of the distance between the objects (r2).

The strength of the bond between the ions of opposite charge in an ionic compound therefore depends on the charges on the ions and the distance between the centers of the ions when they pack to form a crystal.

An estimate of the strength of the bonds in an ionic compound can be obtained by measuring the lattice energy of the compound, which is the energy given off when oppositely charged ions in the gas phase come together to form a solid.

Explanation:

The lattice energies of ionic compounds are relatively large. The lattice energy of NaCl, for example, is 787.3 kJ/mol, which is only slightly less than the energy given off when natural gas burns.

The bond between ions of opposite charge is strongest when the ions are small.

The ionic bond should also become stronger as the charge on the ions becomes larger.

Explanation:

So, we have the formula [tex]q = mc\Delta t[/tex].

Since heat released by the metal is = to the heat absorbed by the water (because they eventually become the same temperature in solution), we can say

[tex]m_{water}C_{water}(T_{water}-T_f) = - m_{metal}C_{metal}(T_{metal} - T_f)[/tex]

Plugging in, we get:

[tex]59.2*4.184*(21- 34.9) = - 27*C_{metal}*(93 - 34.9)[/tex]

Answer:

A) In aldehydes, the carbon is always joined to at least one hydrogen atom.

Explanation:

Aldehydes and Ketones are organic compounds.

The main difference between them is that aldehydes have the carbon atom attached to at least one hydrogen atom.

In ketones, the carbon is attached to another carbon.

To reiterate, the striking difference between the two families is that in alkanals, a hydrogen atom is directly attached to the carbonyl group while in alkanones, no hydrogen atoms is attached to the carbonyl group but two bulky alkyl groups.
