Answer:

Cl^-<NO3^-<H2O<F^-<CN^-

Explanation:

When we talk about base strength we are referring to how easily a chemical specie accepts protons.

The greater the ability of a specie to accept H^+, the greater its base strength.

The order of increasing base strengths of the species listed are shown in the answer above.

At 25°C, gas in a rigid cylinder with a movable piston has a volume of 145 mL and a pressure of 125 kPa. Then the gas is compres

natta225 [31]

Answer:

(4) 230 kPa

Explanation:

The temperature is constant, so the only variables are pressure and volume.

We can use Boyle’s Law.

$p_{1}V_{1} = p_{2}V_{2}$

Divide both sides of the equation by $V_{2}$ .

$p_{2} = p_{1} \times \frac{V_{1}}{ V_{2}}$

$p_{1} = \text{145 kPa}; V_{1} = \text{125 cm}^{3}}$

$p_{2} = ?; V_{2} = \text{80. cm}^{3}$

$p_{2} = \text{145 kPa} \times \frac{\text{125 cm}^{3}}{\text{80. cm}^{3}} = \textbf{230 kPa}$

A typical refrigerator is kept at 4˚C, and a soda can has a pressure of

ss7ja [257]

Answer: The new pressure will be 1.42 atm

Explanation:

To calculate the final pressure of the system, we use the equation given by Gay-Lussac Law. This law states that pressure of the gas is directly proportional to the temperature of the gas at constant pressure.

Mathematically,

$\frac{P_1}{T_1}=\frac{P_2}{T_2}$

where,

$P_1\text{ and }T_1$ are the initial pressure and temperature of the gas.

$P_2\text{ and }T_2$ are the final pressure and temperature of the gas.

We are given:

$P_1=1.18atm\\T_1=4^0C=(4+273)K=277K\\P_2=?\\T_2=60^0C=(60+273)K=333K$

Putting values in above equation, we get:

$\frac{1.18}{277}=\frac{P_2}{333}\\\\P_2=1.42$

Hence, the new pressure will be 1.42 atm

64g of sulfur dioxide (SO2) contains 32g of oxygen. Calculate how much sulfur it contains?

KengaRu [80]

Mass of SO2 = mass of sulfur+ mass of oxygen
⇒ 64 g= mass of sulfur+ 32 g
⇒ mass of sulfur= 64 g-32 g
⇒ mass of sulfur= 32 g.

There is 32 g of sulfur in 64 g of SO2~
