How many grams of glucose, C6H12O6, do you need to make a 50 mL solution that has a concentration of 2.0 M?
PLEASE HELP ASAP!!!!!!

Answer:

Manufacturer's label

Explanation:

In the United States of America, the agency which was established by US Congress and saddled with the responsibility of overseeing all aspects of pollution, environmental clean up, pesticide use, contamination, natural resources and hazardous waste spills is the Environmental Protection Agency (EPA). Also, EPA research solutions, policy development, and enforcement of regulations through the resource Conservation and Recovery Act.

The Environmental Protection Agency (EPA) is the governmental agency set up to ensure that various industries, factories and people comply with laws and regulations concerning the environment i.e it is an agency established to oversee and enforce environmental compliance by the people.

According to EPA, it's mandatory that companies that are into the production of toxic and potentially hazardous chemicals affix a label to the container of their products.

Hence, a manufacturer's label is a kind of label affixed to a chemical container by the manufacturers to display the chemical name, potential hazards, precautions, supplier information, and written and graphic hazard warnings for better understanding and proper use by the end users.

The manufacturers label is the one, which is affixed to a chemical container and displays the chemical name, precautions, potential hazards, supplier information, and graphic and written hazard warnings.  

• According to the Hazard Communication Standard or HCS, the labels refer to an appropriate group pf printed, written, or graphic informational elements concerning a hazardous chemical, which are affixed to, attached or printed to the immediate container of a hazardous chemical.  

• The HCS needs the chemical manufacturers to ensure that each container of hazardous chemicals leaving the workplace is tagged, labelled, or marked with the product identifier, hazard statement, signal word, precautionary statements, and pictograms. Such labels are termed as the manufacturer's label.  

Thus, it the manufacturer's label, which is affixed to a chemical container and displays the chemical name, precautions, potential hazards, supplier information, and graphic and written hazard warnings.

Answer:

False

Explanation:

chemically stable compounds are stable so they do not break down quickly.

Answer:

I think False

As

stable compounds are of lower energy and have a balanced charge. ... So, very loosely, a compound could be said to be stable when it is low in potential energy, has a neutral or spread out charge, and can be used in regular conditions.

THAT'S WHY THEY DO NOT BREAK DOWN EASILY

Well The Definiton of Ammonia is colourless, pungent gas composed of nitrogen and hydrogen. ... It is the simplest stable compound of these elements and serves as a starting material for the production of many commercially important nitrogen compounds.

Answer:

This illustrates Boyle's law, which states that a gas expands if the pressure decreases while all other variables are kept constant. When heating a marshmallow in a microwave, some moisture inside the marshmallow evaporates, adding gas to the bubbles. In addition, a warmer gas pushes outward with more force.

A. They will attract each other

b. They will repel each other

C. Nothing will happen to them

d. They will get heated up

The answer is they will attract each other

Explanation:

This is because the charge from the rubbing of ebonite and acetate to a wool is called triboeletric effect.

When ebonite is rubbed with a wool it will produce negative charge, the electrons around it will be negative but when acetate is rubbed with it, it will produce positive charge. This two will attract each other because unlike charges(negative and positive) attract each other.

Answer:

26 psi

Explanation:

Since the question is between pressure and temperature, you use Gay-Lussac's Law: (P1/T1)=(P2/T2) It's saying that the initial pressure divided by the initial temperature is equal to the final pressure divided by the final temperature.

1. Convert C to Kelvin by adding 273: 18+273=291 & 24+273=297

2. Input the numbers into the equation: (25 psi/291 K)=(P2/297 K)

3. Cross multiply 25 and 297: 25*297=7425.0000

4. Divide by 291: 7425/291=25.5155

5. Round to the correct number of sig figs (or however many the equation says to round to): 26 psi

Answer:

2.5

Explanation:

The given costs for the purchase and delivery of the cupcakes are;

The cost of 10 cupcakes and the delivery fee = $30

The cost of 25 cupcakes and the delivery fee = $67.50

Let 'c' represent the fixed cost of delivery of the cup cakes, and let 'x' represent the cost of each cup cake, we have;

30 = 10·x + c...(1)

67.50 = 25·x + c...(2)

Subtracting equation (1) from equation (2) gives;

67.50 - 30 = 37.50 = 25·x - 10·x + c - c = 15·x

∴ x = 37.50/15 = 2.5

The cost of each cupcake, x = 2.5

(∴ The delivery fee = 30 - 10 × 2.5 = 5)

The cost of each cupcake is 2.5.

Answer:1.59

Explanation: For every mol of Ca(OH)2 there are two moles of OH so the concentration of OH is .013 x2 =.026 M OH

pOH = - log [OH] so -log .026 = 1.59

pOH is the negative logarithm of hydroxide ion concentration. 1.59 is the pOH of a 0.013 M Ca(OH)₂ solution.

The term pOH is defined as the negative of the logarithm of the OH− ion concentration. It is represented by the formula  pOH = - log [OH−].

pOH is the activity of acidity or alkalinity of a solution by determining the concentration of OH− ions.

If the pOH value is less than 7, the solution is basic. If the pOH value is equal to 7, the solution is neutral. If the pOH value is more than 7, the solution is acidic.

For every mol of Ca(OH)₂ there are two moles of hydroxide therefore, the concentration of OH is 0.013 x 2 = 0.026 M OH

According to the formula of pOH

pOH = - log [OH]

-log .026 = 1.59

Thus, the pOH of a 0.013 M Ca(OH)₂ solution is 1.59.

Answer:

b. .28 M KCI

Explanation:

Use the dilution formula.

C₁V₁ = C₂V₂

C₂ = C₁V₁/V₂

C₂ = 1.6*0.175 / 1.0

C₂ = 0.28

The new concentration of the solution of KCl which is diluted to a new volume of 1.0 L is  0.28 M KCI.

Concentration is the abundance of substance or constituent divided by the volume of the mixture.

By the dilution formula

C₁V₁ = C₂V₂

C₂ = C₁V₁/V₂

The concentration is 1.6 M

The volume of KCl is 0.175

The new volume v2 is 1.0 l

Putting the values in the equation

C₂ = 1.6 × 0.175 / 1.0

C₂ = 0.28

Thus, the correct option is b. 0.28 M KCI.

The complete question is: Is the compound [tex]FeCl_{3}[/tex] ionic or covalent ?

Answer: Compound  [tex]FeCl_{3}[/tex] is an ionic in nature.

Explanation:

When a metal atom combines with a non-metal atom then transfer of electrons take place from metal towards the non-metal. As a result, an ionic bond is formed between the atom and compound formed is called an ionic compound.

For example, [tex]FeCl_{3}[/tex] compound contains Fe atom which is a metal and Cl atom which is a non-metal. Hence, electrons will be transferred from Fe atom to the Cl atom forming an ionic bond.

Hence, [tex]FeCl_{3}[/tex] is an ionic compound.

Thus, we can conclude that [tex]FeCl_{3}[/tex] is an ionic compound.

Answer:

[tex]\boxed {\boxed {\sf 0.0014 \ mol \ Cu}}[/tex]

Explanation:

We are asked to convert particles to moles.

1 mole of any substance contains the same number of particles (atoms, molecules, formula units). This is Avogadro's Number or 6.022*10²³.

In this problem, the particles are atoms of copper. So, 1 mole of copper contains 6.022*10²³ atoms of copper

Use Avogadro's Number to make a ratio.

[tex]\frac{ 1 \ mol \ Cu}{ 6.022*10^{23} \ atoms \ Cu}[/tex]

We are trying to convert 8.3*10²⁰ atoms of copper to moles, so we multiply that value by the ratio.

[tex]8.3*10^{20} \ atoms \ Cu*\frac{ 1 \ mol \ Cu}{ 6.022*10^{23} \ atoms \ Cu}[/tex]

The units of "atoms Cu" will cancel.

[tex]8.3*10^{20}\frac{ 1 \ mol \ Cu}{ 6.022*10^{23} }[/tex]

Condense the expression into 1 fraction.

[tex]\frac{8.3 *10^{20}}{ 6.022*10^{23} } \ mol \ Cu[/tex]

[tex]0.001378279641 \ mol \ Cu[/tex]

The original measurement of atoms has 2 significant figures, so our answer must have the same. For the number we calculated that is the ten-thousandths place.

The 7 in the hundredth thousandth place tells us to round the 3 up to a 4.

[tex]0.0014 \ mol \ Cu[/tex]

8.3*10²⁰ atoms of copper are equal to 0.0014 moles of copper.

Answer:

12 g/mol

Explanation:

From Avogadro's law;

V1/n1 = V2/n2

V1 =  5.0 dm^3

n1 = 15 g/26 g/mol = 0.6 moles

V2 = 1.0 dm^3

n2 = ?

V1n2 = V2n1

n2 = V2n1/V1

n2 = 1 * 0.6/5

n2 = 0.12 moles

Molar mass= mass of gas D/number of moles of gas D

Molar mass= 1.4 g/0.12 moles

Molar mass= 12 g/mol
