Answer:

Mass = 96g

Explanation:

Molarity = number of moles/volume of solvent

According to the provided information, volume = 1.55L, Molarity = 1.55M

number of moles (n) = molarity × volume

n = 1.55 × 1.55

n = 2.4025

n = 2.40mol

For NaOH, molar mass = 23 + 16 + 1 = 40g/mol

mole = mass/molar mass

Mass = molar mass × mole

Mass = 40 × 2.40

Mass = 96g

Answer:

33

Explanation:

The atomic number of an element configuration 2,8, 8,2,13​ is 33.

The electron configuration is defined as the arrangement of electrons in atomic or molecular orbitals of an atom. The sum of electrons in different orbitals shown in the electron configuration represents the atomic number of the atom.

So, atomic number of the element configuration 2,8, 8,2,13​ is 33.

Explanation:

Mass of KCl= 19.57 g

Given

12.6 g of Oxygen

Required

mass of KCl

Solution

Reaction

2KClO3 ⇒ 2KCl + 3O2

mol O2 :

= mass : MW

= 12.6 : 32 g/mol

= 0.39375

From the equation, mol KCl :

= 2/3 x mol O2

= 2/3 x 0.39375

=0.2625

Mass KCl :

= mol x MW

= 0.2625 x 74,5513 g/mol

= 19.57 g

Answer: [tex]_{70}^{177}\textrm{Yb}\rightarrow _{71}^{177}\textrm{Lu}+_{-1}^{0}\textrm{e}[/tex]

Explanation:

Answer:

Deciliter = 0.1 L

Explanation:

The options are unit of volume. In order to determine which is greatest, all the options would be converted to liter.

Microliter = 1e-6 L

Mililiter = 0.001 L

Deciliter = 0.1 L

Centiliter = 0.01 L

Among all the options; Deciliter = 0.1 L is the greatest.

Given :

Number of He atoms, [tex]n = 3.4\times 10^{24}[/tex] atoms.

To Find :

How many grams are their in given number of He atoms.

Solution :

We know, molecular mass of He is 4 g. It means that their are [tex]6.022 \times 10^{23}[/tex] atoms in 4 g of He.

Let, number of gram He in [tex]3.4\times 10^{24}[/tex] atoms is x , so :

[tex]x = \dfrac{3.4\times 10^{24}}{6.022\times 10^{23}}\times 4\\\\x = $$22.58\ g[/tex]

Therefore, grams of He atoms is 22.58 g .

Answer:

The answer is 3) same mass more volume

Explanation:

Mass measures the amount of matter in a substance or an object.

Volume measures the amount of space that a substance or an object takes up.

The net ionic equation is applied mainly in neutralization reactions, double displacement reactions and redox reactions. Therefore,  the net ionic equation is Ag⁺(aq)+CO[tex]_3[/tex]²⁻(aq)  [tex]\rightarrow[/tex]Ag[tex]_2[/tex]CO[tex]_3[/tex](s).

The net ionic equation represents a chemical equation of a reaction that give an idea of species that are really participating in the reaction. We can write net ionic equations for those electrolyte which are strong in water.

The balanced net ionic equation is

2AgF(aq)+Na[tex]_2[/tex]CO[tex]_3[/tex](aq)[tex]\rightarrow[/tex]Ag[tex]_2[/tex]CO[tex]_3[/tex](s)+2NaF(aq)

Ag⁺(aq) +F⁻(aq) +Na⁺(aq) +CO[tex]_3[/tex]²⁻(aq) [tex]\rightarrow[/tex]Ag[tex]_2[/tex]CO[tex]_3[/tex](s)+Na⁺(aq) +F⁻(aq)

Ag⁺(aq)+CO[tex]_3[/tex]²⁻(aq)  [tex]\rightarrow[/tex]Ag[tex]_2[/tex]CO[tex]_3[/tex](s)

The net ionic equation cancels out ions that appear on both sides of the reaction arrow because they essentially don't participate in the reaction of interest.

Therefore,  the net ionic equation is Ag⁺(aq)+CO[tex]_3[/tex]²⁻(aq)  [tex]\rightarrow[/tex]Ag[tex]_2[/tex]CO[tex]_3[/tex](s).

Answer:

The amount in grams of CaO that will be produced is 2,302.67824 grams

Explanation:

The reaction between calcium and oxygen to produce calcium oxide (quicklime) can be presented as follows;

2Ca (s) + O₂ (g) → 2CaO (s)

From the above chemical equation, we have;

2 moles of calcium, Ca, react with 1 mole of oxygen gas, O₂, to produce 2 moles of CaO

With the assumption that there is an excess amount of Ca, we have;

The molar mass of O₂ = 32 g/mol

The number of moles, 'n', of O₂ in 657.0 grams of oxygen is therefore;

The number of moles of a substance =  Mass of substance/(Molar mass of substance)

∴ n = 657.0 g/(32 g/mol) = 20.53125 moles

The number of moles of O₂ in the 657.0 grams of oxygen present in the reaction, n = 20.53125 moles

1 mole of O₂ produces 2 moles of CaO, therefore, 20.53125 moles of oxygen will produce 2 × 20.53125 or 41.0625 moles of CaO

The molar mass of CaO = 56.0774 g/mol

Therefore, the mass of 41.0625 moles of CaO is given as follows;

Mass of substance = (The number of moles of a substance) × (Molar mass of substance)

The mass of CaO produced = 41.0625 moles × 56.0774 g/mol = 2,302.67824 g.

Answer: [tex]F(g)+e^-\rightarrow F^-(g)[/tex]

Explanation:

Electron gain enthalpy is defined as energy released on addition of electron to an isolated gaseous atom.  

The amount of energy released will be maximum when the tendency to attract electrons is maximum. As flourine has atomic number of 9 and has electronic configuration of 2,7. It can readily gain 1 electron to attain stable noble gas configuration and hence liberates maximum energy.

[tex]F(g)+e^-\rightarrow F^-(g)[/tex]

Answer:

For producing 0.55 mole of acetic acid, 0.55 mole of ethanol is required.

Explanation:

The balanced equation for this reaction is

CH3CH2OH + O2 --> CH3COOH + H2O

As we can see in this equation, the ration of number of moles of acetic acid to the number of moles of ethanal is equal to [tex]1 : 1[/tex]

Hence, in order to produce one mole of acetic acid, 1 mole of ethanol is required.

Thus, for producing 0.55 mole of acetic acid, 0.55 mole of ethanol is required.

its d because a beta particle has a negative charge

In the case when there is the  negatively charged beta particle so the number of nucleons decreased by one.

In terms of chemistry and physics, a nucleon could be treated as the proton or neutron also it considered as the component of the atomic nucleus. Here the no of nucleons in the nucleus should represent the atom mass number.

So based on this, we can conclude that In the case when there is the  negatively charged beta particle so the number of nucleons decreased by one.

Answer:

Explanation:

1 mol of any chemical is 6.02 * 10^23

x mol of any chemical is 6.31 * 10^24

You should look at this before you put it in  your calculator. You should think roughly 10.

Now you can set it up as a proportion

1/x = 6.02 * 10^23/6.31 * 10^24        Cross multiply

6.02 * 10^23 x = 1 * 6.31 * 10^24      Divide by 6.02 * 10^23

x = 6.31 * 10^24 / 6.02 * 10^23

x = 10.48 mols.

Answer:

becomes runoff and finds its way back to the ocean

Explanation:

Precipitation refers to rainfall that reaches the earth.

Most of the rainfall that reaches the earth becomes runoff and finds its way back to the ocean.

When the rain falls on earth, some evaporates, some enters into the ground while some runs off into rivers and streams. Almost all of the rain water flows into the oceans or other bodies of water.

Hence, most of the rainfall that reaches the earth becomes runoff and finds its way back to the ocean
