What is the name given to the process shown in the diagram

Explanation:

neutralization reaction can be defined as a chemical reaction in which an acid and base quantitatively react together to form a salt and water as products. In a neutralization reaction, there is a combination of H+ ions and OH– ions which form water.

In chemistry, neutralization or neutralisation is a chemical reaction in which acid and a base react quantitatively with each other. In a reaction in water, neutralization results in there being no excess of hydrogen or hydroxide ions present in the solution.

Answer:

A. How hot or cold the substance is.

Explanation:

If we know the temperature of the substance

we can know how hot or cold the substance is.

And as we know temperature is the degree of hotness or coldness of a body.

Answer:

T₂ = 800 K

Explanation:

Given that,

Initial temperature of the gas, T₁ = 127°C = 400 K

Initial volume, V₁ = 10 L

Final volume, V₂ = 20 L

We need to find the new temperature.

The volume of a gas is directly proportional to its Kelvin temperature.

Let T₂ is the new temperature. So,

[tex]\dfrac{V_1}{T_1}=\dfrac{V_2}{T_2}\\\\T_2=\dfrac{V_2T_1}{V_1}\\\\T_2=\dfrac{20\times 400}{10}\\\\T_2=800\ K[/tex]

So, the new temperature of the gas is 800 K.

Answer:

Nitrogen and chlorine have similar electronegativities, making individual N-Cl bond essentially non-polar. therefore its true

Explanation:

Answer:

ion-dipole interaction

Explanation:

Ethanol is a polar molecule due to the presence of the polar O-H group in the molecule. This means that the molecule has a dipole moment.

The positive end of the dipole lies on hydrogen while the negative end of the dipole lies on oxygen.

When KCl is dissolved in ethanol, K^+ ions can interact with the negative end of the dipole in ethanol by ion-dipole interaction.

Answer:

The answer I would go with is A formation of a new substance.

Explanation:

This is because physical change includes changes of state. Some could be changing from a liquid to gas or solid to gas. B is not even an answer that should be considered because it doesn't fit into the category. C and D represents some of the examples of the process of physical change. Like boiling, bubbling, melting, or freezing. So the best would be A.

first find the atomic weight of CH3 which would be

atomic weight: 12.011 (3×1.008) = 36.32 g/mol

then find the moles in the given mass

36.32 ÷ 45.7 = 0.794

I HOPE I'M NOT WRONG I HAVENT DONE CHEM IN SO LONG

Answer:

C. A one (1) is assumed when there is no coefficient

Explanation:

The following chemical equation is given in the attachment:

2H2 + O2 → 2H2O

In this reaction, Hydrogen (H2) and oxygen (O2) gases are the reactants and they combine to form H2O, which is the product. It is necessary that, in accordance to the law of conservation of matter, the same number of atoms of each elements on the reactant side equates that on the product side. When this happens, the equation is said to be BALANCED.

However, to balance an equation, COEFFICIENTS are used. In this equation above, coefficients 2 is used in front of both H2 and H2O but no coefficient is used in front of O2. This is because 1 mole of oxygen is on the reactant and product side respectively. However, one is assumed when no coefficient is written i.e. O2 means 1 mole of oxygen molecule.

Answer:

0.68 mol/L

Explanation:

M=m/l

m is moles and l is liters

Since they gave us the values in the correct units, all we have to do it plug it in

M=0.34 mol/0.5 liters

M=0.68

Answer:

Poisons are used less today than they were in the past because forensic scientists can easily detect many substances and toxins during an autopsy.

The main factor that influenced this change is advancements in forensic toxicology knowledge and technology.

good luck, i hope this helps :)

Explanation:

Today poisons are used less because forensic scientists now have much more equipment and have an easier time at identifying poisons like arsenic, which were not so easy to find in the past. The main factor influencing this change is the new technology and knowledge that was unavailable in the past.

Answer:

~0.14

Explanation:

There are roughly ~0.14 moles in 4.5g of Sulfur. 1 mol = 32.06 g of Sulfur, so we just find the ratio and then multiply.

Answer:

[tex]\boxed {\boxed {\sf About \ 0.14 \ mol \ S }}[/tex]

Explanation:

To convert from grams to moles we must use the molar mass. This can be found on the Periodic Table.

We can use this number as a ratio or fraction.

[tex]\frac{ 32.07 \ g \ S }{1 \ mol \ S }[/tex]

Multiply by the given number of grams: 4.5

[tex]4.5 \ g \ S *\frac{ 32.07 \ g \ S }{1 \ mol \ S }[/tex]

Flip the fraction so the grams of sulfur cancel.

[tex]4.5 \ g \ S *\frac{1 \ mol \ S }{32.07 \ g \ S}[/tex]

[tex]4.5 *\frac{1 \ mol \ S }{32.07 }[/tex]

[tex]\frac{4.5 \ mol \ S }{32.07 }[/tex]

[tex]0.140318054 \ mol \ S[/tex]

The original measurement of grams had 2 significant figures, so our answer must have the same. For the number we calculated, that is the hundredth place.

The 0 in the thousandth place tells us to leave the 4.

[tex]0.14 \ mol \ S[/tex]

There is about 0.14 moles of sulfur in 4.5 grams.

Explanation:

An oxyacid, oxoacid, or ternary acid is an acid that contains oxygen. Specifically, it is a compound that contains hydrogen, oxygen, and at least one other element, with at least one hydrogen atom bonded to oxygen that can dissociate to produce the H+ cation and the anion of the acid.

Answer:

oxyacid, oxoacid

Explanation:

An oxyacid, oxoacid, or ternary acid is an acid that contains oxygen. Specifically, it is a compound that contains hydrogen, oxygen, and at least one other element, with at least one hydrogen atom bonded to oxygen that can dissociate to produce the H+ cation and the anion of the acid.

Answer:

Be^2+

Explanation:

The atomic number indicates the number of protons so the element is Be (beryllium)

So now we know that a neutral atom contains four electrons but there are 2 so that means two electrons were taken away, making it positive. It would be a 2+ charge.
