1 answer:
BARSIC [14]3 years ago
5 0

Answer:

D. none of the above

Explanation:

A. is wrong because pressure and volume have an inverse relationship. When one increases the other decreases, this is not an option.

B. is wrong because temperature and volume have a proportional relationship. One one goes up, the other goes up or vice versa.

C. is wrong because volume cannot increase the then decrease at the same time.

a solution of common salt and a sample of muddy water are placed separately in two breakers. which one is hetrogeneous and which
arsen [322]

Answer:

a solution of salt is homogeneous mixture

a sulution of muddy water is heterogeneous mixture

Explanation:

reason for salt and water as homogeneous mixture because water dissolves salt easily unlikely heterogeneous mixture in which water cannot dissolve mud in it

Calculate the average molar bond enthalpy of the carbon-hydrogen bond in a ch4 molecule.
balandron [24]
<span>The average molar bond enthalpy of the carbon-hydrogen bond in a CH4 molecule is 416 KJ/mol. (+716.7 + (4 x 218) - (- 74.6) ) / 4 = + 1663.3 / 4 = 416</span>

How many grams of KCl 03 are needed to produce 6.75 Liters of O2 gas measured at 1.3 atm pressure and 298 K?
Nina [5.8K]

11.48-gram of KCl0_3 are needed to produce 6.75 Liters of O_2  gas measured at 1.3 atm pressure and 298 K

<h3>What is an ideal gas equation?</h3>

The ideal gas law (PV = nRT) relates the macroscopic properties of ideal gases. An ideal gas is a gas in which the particles (a) do not attract or repel one another and (b) take up no space (have no volume).

First, calculate the moles of the gas using the gas law,

PV=nRT, where n is the moles and R is the gas constant. Then divide the given mass by the number of moles to get molar mass.

Given data:

P= 1.3 atm

V= 6.75 Liters

n=?

R= 0.082057338 \;L \;atm \;K^{-1}mol^{-1}

T=298 K

Putting value in the given equation:

\frac{PV}{RT}=n

n= \frac{1.3 \;atm\; X \;6.75 \;L}{0.082057338 \;L \;atm \;K^{-1}mol^{-1} X 298}

Moles = 0.3588 moles

Now,

Moles = \frac{mass}{molar \;mass}

0.3588 moles = \frac{mass}{32}

Mass= 11.48 gram

Hence, 11.48-gram of KCl0_3 are needed to produce 6.75 Liters of O_2 gas measured at 1.3 atm pressure and 298 K
