Answer:

797 mm hg = 1.04868 atm

Explanation:

1 atm = 760 mm hg

797 mm hg to atm is 1.0468 atm

Pressure is defined as the physical force exerted on an object. The force applied is perpendicular to the surface of objects per unit area.

There are many different types of units and prefixes that may be used in general practice to reflect pressure. Thus, it is ensured that all the measurements and their respective units are in the same framework when conducting pressure calculations.

Pascal is the SI unit of pressure, and is the basic pressure unit in the SI (the International System of Units) system.

Given,

Pressure = 797 atm

1 mm Hg = 0.00131579 atm

797 mm Hg = 0.00131579 × 797

= 1.04868 atm

Answer: 2

Explanation:

A combustion reaction must include O2 as a reactant.

An inorganic substance almost never includes carbon.

So, by process of elimination:

1. Carbon is a reactant = probably not

2. Has O2, no carbon = yes

3. O2 is not a reactant = no

4. Carbon is a reactant = probably not

An example of the combustion of an inorganic substance is:

2 Ca + O₂ ⇒ 2 CaO

We have 4 reactions and we want to determine which is an example of combustion of an inorganic substance.

A combustion reaction is a reaction in which a substance reacts with oxygen gas, releasing energy in the form of light and heat.

Organic substances always contain carbon while most inorganic substances do not contain carbon.

Let's consider the following reactions.

This is a combustion reaction but C₃H₈ is an organic substance.

This is an example of the combustion of an inorganic substance.

This is not a combustion reaction.

This is a combustion reaction but CH₃COOH is an organic substance.

Answer:

8.235 kg

Explanation:

Mass of the cylinder = 4.8 kg

The capacity (volume) of the cylinder = 50 liters

As 1 m^3 = 1000 liters

So, the volume of the cylinder, v= 0.05 m^3

The volume of filled nitrogen, v= 0.05 m^3

Pressure of filled nitrogen, p = 60 atm = 60\times 101325 Pa

Assuming that the nitrogen gas is at room temperature which is 25-degree centigrade,

So, the temperature of nitrogen gas, T=273+25= 298 K

By using the ideal gas equation, pv=nRT

Where n is the number of moles, R is the universal gas constant, R = 8.314 J/mol·K

Putting all the values in the ideal gas equation, we have

(60 x 101325)0.05 = n (8.314) x (298)

n= (60 x 101325 x 0.05)/(8.314 x 298)

n=122.69 moles

As the  molar mass of nitrogen is 28, so the total mass of the nitrogen in the cylinder, m= 122.69 x 28 = 3435.32 grams = 3.435 kg.

Hence, the new mass of the cylinder = 4.8+3.435=8.235 kg

same number of each kind of atom appears in the reactants and in the products

Answer:

38.3 miles

Explanation:

First, we convert 1.95 gallons to mililiters:

Then we calculate how many grams of octane are available for the reaction, using its density:

Now we convert octane grams into octane moles, using its molar mass:

Then we calculate how many kJ are produced from the combustion of  44.78 mol C₈H₁₈, if 2 moles produce 10900 kJ:

We calculate how many seconds is the car available to keep going, if it spends 115 kJ per second:

We convert seconds to hours:

Finally we calculate the distance:

width=10cm

length=2xwidth=2x10=20cm

height=width/2=10/2=5

V=w*l*h=10*20*5=1000cm^3

Answer:

1000cm^3

Explanation:

first collect what is known

width 10cm

length 2×width (2×10cm) =20cm

height width/2 (10cm/2) =5cm

now if we use the formula for finding volume of a cuboid that has length, width and height known;

V = l×w×h

= 20cm × 10cm × 5cm

= 1000cm^3

Answer:

1. The properties of matter include any traits that can be measured, such as an object's density, color, mass, volume, length, malleability, melting point, hardness, odor, temperature, and more.

2. A chemical property is a characteristic of a particular substance that can be observed in a chemical reaction.

3. Toxicity and acidity.

4. A chemical property describes the ability of a substance to undergo a specific chemical change. A chemical reaction is a process that occurs when one or more substances are changed into one or more new substances.

5. The five basic types of chemical reactions are combination, decomposition, single-replacement, double-replacement, and combustion. Analyzing the reactants and products of a given reaction will allow you to place it into one of these categories. Some reactions will fit into more than one category.

claim : Tissue engineering is good for the future and has a positive impact on the future because tissue engineering restores aged, damaged or lost tissues/organs with artificial tissues in a way past medicines or technology has not.

evidence: The infographic states, “This science field provides opportunities for helping many people replace dead or injured organs with new ones. In doing so, it will give them a healthier, more productive life. This field is just beginning, and it is sure to change the length and quality of life of many people in the future.“

reasoning: Many people can benefit from tissue engineering because they can have dead or injured organs replaced with new ones. Tissue engineering is just the beginning and is still being conducted and tested , but as technology gets more advanced and advanced, tissue engineering will improve peoples lives the way medicines and past technology has never done.

Answer:

760 uM

Explanation:

A biochemist carefully measures the molarity of magnesium ion in 47, mL of cell growth medium to be 97 uM. Unfortunately, a careless graduate student forgets to cover the container of growth medium and a substantial amount of the solvent evaporates. The volume of the cell growth medium falls to 6.0 mL. Calculate the new molarity of magnesium ion in the cell growth medium Be sure your answer has the correct number of significant digits.

The problem here is that the amount of magnesium ion remains the same irrespective of the volume.

Amount of magnesium in the growth medium = molarity x volume

    = 97 x [tex]10^{-6}[/tex] x 47 x [tex]10^{-3}[/tex] = 4.559 x [tex]10^{-6}[/tex]

Then, the volume reduced to 6.0 mL, the new molarity becomes;

molarity = mole/volume

       = 4.559 x [tex]10^{-6}[/tex]/6 x [tex]10^{-3}[/tex] = 7.598333 x [tex]10^{-4}[/tex] M = 759.83333 uM

To the correct number of significant digits = 760 uM
