Metals have a low electron affinity- a less likely chance to gain electrons because they want to give up their valence electrons rather than gain electrons, which require more energy than necessary.

The volume of a sample of gas measured at 27 °C is 10.0 dm . What is the temperature when the volume is reduced to 9.0 dm at the

Mars2501 [29]

Answer:

$T_2=24.3^{\circ} C$

Explanation:

Given that,

The volume of a sample of gas measured at 27 °C is 10.0 dm.

We need to find the temperature when the volume is reduced to 9.0 dm at the same pressure.

According Charles law,

$\dfrac{V_1}{T_1}=\dfrac{V_2}{T_2}$

Where, T₂ is new temperature

$T_2=\dfrac{V_2T_1}{V_1}\\\\T_2=\dfrac{9\times 27}{10}\\\\T_2=24.3^{\circ} C$

So, the new temperature is $24.3^{\circ} C$ .

How many inches is in 10 cm? Use dimensional analysis to show your work. Include the work in your answer.

Mumz [18]

Answer:

To get the answer divide 10cm by 2.54

Explanation:

$\frac{10}{2.54} \\ = 10 \div \frac{254}{100} \\ = 10 \times \frac{100}{254} \\ = \frac{1000}{254} = 3.937inches$

For the reaction PCl5(g) + heat PCl3(g) + Cl2(g), what will happen when the volume is increased?

Fiesta28 [93]

Answer: There will be a shift toward the products.

The effect of increasing volume will be similar to decreasing pressure, it will shift the equilibrium into the side with higher molecule count. In the reaction above, the product molecule count is 1 (one PCl5) while the product is 2 (one PCl3 + one Cl2). So, increasing volume will increase the rate of product formation.

What happens when you drop iodine on a leaf?

insens350 [35]

When you drop iodine on a leaf you may observe a colour change of orange/brown to a blue/black complex.

This is because in the leaf there are starch molecules that form a blue/black complex with the starch molecules.

hope that helps :)
