A typical carbon monoxide detector will sound it's alarm if it detects 0.050 g of CO, HOw many molecules of carbon monoxide are
Colt1911 [192]

Answer:

1.07×10²¹ molecules are needed to sound the alarm

Explanation:

Let's convert the mass of CO to moles, to determine the amount of molecules.

0.05 g . 1 mol / 28 g = 1.78×10⁻³ moles

Now we can determine the number of molecules with the NA

1 mol has 6.02×10²³ molecules

1.78×10⁻³ moles may have (1.78×10⁻³ .  6.02×10²³) / 1 = 1.07×10²¹ molecules

Question 1 (2 points)
natulia [17]

Temperature is the average kinetic energy of gas molecules.

<h3>What is absolute zero?</h3>

The term absolute zero refers to the hypothetical point where the energy of molecules is zero. It is the point where all of their motion stops completely.

In a liquid, the movement of the molecules is more significant than in a solid. If you keep increasing the temperature of a liquid, it will boil and become a gas.

Matter contains energy which depends on the temperature of matter. To remove the energy of matter, you have to lowering its temperature.

The addition of energy to matter occurs when matter is heated. Hence, you add energy to matter by heating it.

The molecules at warm temperatures differ from the molecules at cool temperatures because the molecules at warmer temperatures move around more.

The air on a hot day compares to the air on a cool day in the sense that on a hot day, air molecules have more energy.

Temperature is depends on the kinetic energy of molecules. Hence, the best description of temperature is motion of molecules.

The temperature of a body is the average kinetic energy of its molecules.  When two things that are not touching have the same temperature their molecules move at the same average speed.

Since a liquid receives energy when it is heated, when the liquid is boiled beyond its boiling point, It will become a gas.

The difference between heat and temperature is that temperature measures the motion of molecules, and heat is the energy of that motion.

Rank the following alkenes in order of increasing stability of the double bond towards addition of HBr:
ASHA 777 [7]

Answer:

2,3-dimethyl-2-butene > 3-methyl-3-hexene > cis-3-hexene > 1-hexene

Explanation:

According to Saytzeff rule, the more highly substituted an alkene is, the more stable it is. Since this is so, 2,3-dimethyl-2-butene will be the most stable of all the alkenes listed because it is the most substituted alkene.

Let us also note that terminal alkenes are the least stable because the pi bonds of the alkenes are least stabilized by alkyl groups. This implies that 1-hexene is the least stable alkene among the listed alkenes.

On a cool, rainy day, the barometric pressure is 698 mmHg. Calculate the barometric pressure in centimeters of water (cmH2O). De
lesantik [10]

Answer:

Barometric pressure is 942.3 cm of column of water.

Explanation:

We can measure barometric pressure by measuring the height h of a column of fluid (this column of fluid exerts the same pressure as the column of air of which we are measuring pressure) using the following formula:

P = \rho*g*h\\

Where ρ is the density of the fluid used and g the acceleration of gravity.

Knowing that both the column of mercury (to match units, we know that 698 mmHg are the same as 69.8 cmHg) and the column of water are representing the same pressure, we can match expressions and find h for the column of water:

\rho_{Hg} *g*h_{Hg} =\rho_{Water} *g*h_{Water}\\ \\h_{Water}=\frac{rho_{Hg} *g*h_{Hg}}{\rho_{Water} *g} = \frac{13.5g/mL *9.8m/s^{2} *69.8cm}{1g/mL *9.8m/s^{2}}=942.3 cmH_{2}O

A 10.0-L rigid container holds 3.00 mol H2 gas at a pressure of 4.50 atm. What is the temperature of the gas?
prisoha [69]
We can approach this problem using the ideal gas law which is as follows:

PV = nRT

P = pressure
V = volume
n = number of moles
R = gas constant, 0.08206 Latm/Kmol
T = temperature

We are asked to solve for temperature and can rearrange the equation to solve for T:

PV = nRT
T = PV/nR

Now we simply plug in the data to solve for T:

T = (4.50 atm)(10.0 L)/(3.00 mol)(0.08206 Latm/Kmol)
T = 183 K

The temperature of the gas is 183 K.
