c5h12 with one tertiary carbon

Answer:

30.1 g NaCl

Explanation:

Your first conversion is converting grams NaOH to moles of NaOH using its molar mass (39.997 g/mol). Then, use the mole ratio of 1 mol NaCl for every 1 mol NaOH to get to moles of NaCl. Then finally multiply by the molar mass of NaCl (58.44 g/mol) to get grams of NaCl.

20.6 g NaOH • (1 mol NaOH / 39.997 g NaOH) • (1 mol NaCl / 1 mol NaOH) • (58.44 g NaCl / 1 mol NaCl) = 30.1 g NaCl

Answer:

[tex]3.0molMg(OH)_2[/tex]

Explanation:

Hello there!

In this case, for these types of acid-base neutralizations, it is crucial to firstly set up the chemical reaction taking place between the acid and the base; in this case HCl and Mg(OH)2 respectively, whose products are obtained by switching around the anions and cations as shown below:

[tex]HCl(aq)+Mg(OH)_2(aq)\rightarrow MgCl_2(aq)+H_2O(l)[/tex]

Which must be balanced to accurately predict the mole ratio on the reactants side:

[tex]2HCl(aq)+Mg(OH)_2(aq)\rightarrow MgCl_2(aq)+2H_2O(l)[/tex]

Whereas we can see a 2:1 mole ratio of the acid to the base; thus, the moles of Mg(OH) required for the neutralization of 6.0 moles of HCl turn out to be:

[tex]6.0molHCl*\frac{1molMg(OH)_2}{2molHCl} \\\\=3.0molMg(OH)_2[/tex]

Answer:

1.022ppm is the unknown concentration of the metal

Explanation:

Based on Lambert-Beer law, the increasing in signal of a detector is directly proportional to its concentration.

The unknown concentration (X) produces a signal of 0.255

99mL * X + 1mL * 100ppm / 100mL produces a signal of 0.502

0.99X + 1ppm produce 0.502, thus, X is:

0.255 * (0.99X + 1 / 0.502) =

X = 0.503X + 0.508

0.497X = 0.508

X =

1.022ppm is the unknown concentration of the metal

Explain:- 22.4L Imol Page 10 Many gas law problems involve calculating the volume of a gas produced by the reaction of volumes of other gases. The problem solving strategy that we have used throughout your chemistry course is still the same. 10.

The volume would 9.23 moles of oxygen gas occupy at 825 mmHg and 45 C 22.4L.

According to the Ideal Gas Law, all gases contain the same number of molecules at the same temperature, pressure, and volume (but not the same mass).

When the temperature and pressure are close to the point of transforming into a liquid or solid, the Ideal Gas law does not apply.

There are four governing assumptions for a gas to be "ideal": The volume of the gas particles is insignificant. The gas particles are all the same size and have no intermolecular forces with one another. According to Newton's Laws of Motion, the gas particles move at random.

Given :

Volume = ?

Number of moles = 9.23 moles

Temperature = 318K

Pressure = 825 mmHg = 1.08 atm

By an ideal gas equation

PV = nRT

V = nRT/ P

= 9.23 × 0.0821 × 318 /  1.08

= 22.4L

Thus, The volume would 9.23 moles of oxygen gas occupy at 825 mmHg and 45 C is 22.4L.

Answer:

ΔH°r = -114.40 kJ

Explanation:

Let's consider the following balanced equation.

4 HCl(g) + O₂(g) ⇒ 2 H₂O(g) + 2 Cl₂(g)

We can calculate the standard enthalpy change of the reaction (ΔH°r) using the following expression.

ΔH°r = ∑np × ΔH°f(p) - ∑nr × ΔH°f(r)

where

ΔH°r = 2 mol × ΔH°f(H₂O(g)) + 2 mol × ΔH°f(Cl₂(g)) - 4 mol × ΔH°f(HCl(g)) - 1 mol × ΔH°f(O₂(g))

ΔH°r = 2 mol × (-241.82 kJ/mol) + 2 mol × 0 kJ/mol - 4 mol × (-92.31 kJ/mol) - 1 mol × 0 kJ/mol

ΔH°r = -114.40 kJ

Answer:

Basically, fragrances reach other person through sense of smell. So, the strength of the fragrances depends a lot on its evaporation, which is strongly related to the boiling point. Esters with higher molecular weight do not have a strong fragrance because it has a higher boiling point.

Explanation:

The symbols for three different cations with 14 protons are Si²⁺, Si⁴⁺, and Si³⁺. An element with 14 protons must be silicon, Si. Its electron configuration is [Ne] 3s²3p², so it could lose up to four valence electrons. The most likely cations are Si²⁺, Si⁴⁺, and Si³⁺ (or Si⁺)

Answer:

In materials science, an intrinsic property is independent of how much of a material is present and is independent of the form of the material, e.g., one large piece or a collection of small particles. Intrinsic properties are dependent mainly on the fundamental chemical composition and structure of the material.

Answer:

1.1 × 10² g

Explanation:

Step 1: Given data

Step 2: Calculate the moles of Mg(NO₃)₂ (solute)

Molarity is equal to the moles of solute (n) divided by the liters of solution.

C = n/V

n = C × V

n = 0.50 mol/L × 1.500 L = 0.75 mol

Step 3: Calculate the mass corresponding to 0.75 moles of Mg(NO₃)₂

The molar mass of Mg(NO₃)₂ is 148.3 g/mol.

0.75 mol × 148.3 g/mol = 1.1 × 10² g

Answer:

Answer Below Hope Its Correct.

Explanation:

A weather front is a transition zone between two different air masses at the Earth's surface. Each air mass has unique temperature and humidity characteristics. Often there is turbulence at a front, which is the borderline where two different air masses come together. The turbulence can cause clouds and storms.

Instead of causing clouds and storms, some fronts just cause a change in temperature. However, some storm fronts start Earth's largest storms. Tropical waves are fronts that develop in the tropical Atlantic Ocean off the coast of Africa. These fronts can develop into tropical storms or hurricanes if conditions allow.

Fronts move across the Earth's surface over multiple days. The direction of movement is often guided by high winds, such as Jet Streams.  Landforms like mountains can also change the path of a front.

There are four different types of weather fronts: cold fronts, warm fronts, stationary fronts, and occluded fronts.

Iron is changed into steel by blowing oxygen through the molten metal from the Blast Furnace. This oxidises the impurities in the molten metal. Carbon is a major impurity in Blast Furnace metal.

Answer:

A. The reaction proceeds in the forward and reverse directions at the same rate.

B. Both the forward and the reverse reactions are achievable.

D. There is no net change in concentrations of reactants and products.

Explanation:

Chemical equilibrium can be defined as the state of a reversible reaction in which the concentration (rate) of the forward reaction is equal to the concentration (rate) of the backward or reverse reaction. Thus, both the reactants and products of the chemical equation don't have the tendency to change with respect to time.

Hence, the options that are true of chemical equilibria include the following;

I. The reaction moves in both forward and reverse directions simultaneously i.e at the same rate.

II. The chemical equation can attain both forward and reverse reactions.

III. The concentrations of both reactants and products are the same i.e there's no net change.
