132.67 K is the temperature at which 55 grams of chlorine gas exert a pressure of 245 kPa at a volume of 3.4 liter.

Explanation:

Data given:

mass of chlorine gas  = 55 grams

atomic mass of chlorine gas = 71 grams/mole

pressure of chlorine gas = 245 kPa 0R 2.41 atm

volume of the chlorine gas = 3.4 litres

temperature of the chlorine gas = ?

R = 0.08201 Latm/moles K

n =?

Assuming that chlorine behaved like ideal gas, the formula used will be,

PV = nRT

number of moles = \frac{mass}{atomic mass of 1 mole}

number of moles= \frac{55}{71}

number of moles = 0.77

putting the values in ideal gas equation:

T = \frac{2.41 X 3.4}{0.08021 X 0.77}

T = 132.67 K

temperature is 132.67 K

A. Energy is transferred to different forms
Luden [163]

Answer:

A. Energy is transferred to different forms .

Explanation:

Hello!

In this case, we need to consider the law of conservation of mass and energy which states that mass and energy cannot be neither created nor destroyed, just modified; it means we can rule out B. and C. so far.

Moreover, since D. is actually true for combustion reactions because they are used to provide energy in industrial operations, this is not the concern here because a combustion reaction is not considered.

Therefore the correct option is A. Energy is transferred to different forms as the energy provided by Rose is transferred to the pendulum system .

Best regards!

Which of the following is altered by a catalyst?
Vika [28.1K]
<span>In chemistry, a catalyst can speed up the reaction (or make it initiate easier) by altering the activation energy, lowering it enough to allow the reactants to react more easily. Some negative catalysts or inhibitors can do the same by increasing the activation energy.
