Answer:

The correct answer is option C) "Handle your thermometer with care. When you remove it from your drawer be sure to hold both ends of the thermometer so that it does not slip out".

Explanation:

Handling a thermometer with care is part of the laboratory safety precautions that should be considered regarding to the reactivity of metals. Old thermometers are based on the element mercury, a shining metal that is the only element that is in liquid state on room temperature conditions. Mercury is very toxic, and is particularly dangerous because it vaporizes at room temperature and it could be inhaled.

The formula weight of potassium dichromate (k2cr2o7) is __________ amu.

Gre4nikov [31]

The given compound is $K_{2}Cr_{2}O_{7}$

Each formula unit of $K_{2}Cr_{2}O_{7}$ has 2 mol Potassium (K) atoms, 2 mol Chromium (Cr) atoms and 7 mol Oxygen (O) atoms.

Atomic weight of potassium is 39.0983 amu

Atomic weight of Chromium is 51.9961 amu

Atomic weight of Oxygen is 15.9994 amu.

Therefore the formula weight of $K_{2}Cr_{2}O_{7} =$

$2 * 39.0983 amu + 2 * 51.9961 amu + 7 * 15.9994 amu$

= 294.1846 amu

The volume of a gas is 1.15 L at STP. At what temperature would the volume of the gas increase to 1.56 L, if the pressure is dec

denis23 [38]

A gas occupies 1.15 L at standard pressure and temperature and 1.56 L at 317 K and 650 mmHg, assuming ideal behavior.

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

An ideal gas is a gas whose behavior can be explained through ideal gas laws. One of them is the combined gas law.

A gas occupies 1.15 L (V₁) at STP (T₁ = 273,15 K and P₁ = 760 mmHg). We can calculate the temperature (T₂) at which V₂ = 1.56 L and P₂ = 650 mmHg, using the combined gas law.

$\frac{P_1 \times V_1}{T_1} = \frac{P_2 \times V_2}{T_2}\\T_2 = \frac{P_2 \times V_2 \times T_1}{P_1 \times V_1} = \frac{650mmHg \times 1.56 L \times 273.15K}{760mmHg \times 1.15 L} = 317 K$

A gas occupies 1.15 L at standard pressure and temperature and 1.56 L at 317 K and 650 mmHg, assuming ideal behavior.
