The pressure of the oxygen gas collected : 718 mmHg

<h3>Further explanation</h3>

Given

P tot = 748 mmHg

P water vapour = 30 mmHg

Required

P Oxygen

Solution

Dalton's law of partial pressures states that the total pressure of a mixture of gases is equal to the sum of the partial pressures of the component gases

Can be formulated:

P tot = P1 + P2 + P3 ....

The partial pressure is the pressure of each gas in a mixture

P tot = P H₂O + P Oxygen

P Oxygen = 748 mmHg - 30 mmHg

P Oxygen = 718 mmHg

Find the volume in milliliters occupied by 454 g of copper, which has a density of 8.92 g/mL.​
Alecsey [184]

Answer:

<h2>50.90 mL</h2>

Explanation:

The volume of a substance when given the density and mass can be found by using the formula

volume =  \frac{mass}{density} \\

From the question

mass = 454 g

density = 8.92 g/mL

We have

volume =  \frac{454}{8.92}  \\  = 50.8968

We have the final answer as

<h3>50.90 mL</h3>

Hope this helps you

Order of decreasing atomic radius largest to smallest
anastassius [24]
As you go from left to right and down to up on the periodic table, atomic radius decreases. This would make helium the smallest and francium the largest.

A 312 g sample of a metal is heated to 277.845 °C and plunged into 200 g of water at a temperature of 11.945 °C. The final tempe
tigry1 [53]

Answer:

The specific heat capacity of the metal is 1.307 J/g °C

Explanation:

<u>Step 1:</u> Data given

mass of the metal = 312 grams

initial temperature of the metal ( before plunged in the water) = 277.845 °C

initial temperature water = 11.945 °C

Final temperature of water (and aslo the metal) = 99.062 °C

Specific heat capacity of wayer = 4.184 J/g °C

<u>Step 2:</u>  Calculate the specifi heat capacity of the metal

Loss of Heat of the Metal = Gain of Heat by the Water

Qmetal = -Qwater

m(metal) * C(metal) * ΔT(metal) = - m(water) * C(water) * ΔT(water)

with mass of metal = 312 grams

with C(metal) = TO BE DETERMINED

with ΔT (metal) = 99.062 - 277.845 = -178.783 °C

with mass of water = 200 grams

with C(water) = 4.184 J/°C * g

with ΔT (water) = 99.062 - 11.945 = 87.117 °C

312 * C(metal) * -178.783  = - 200* 4.184 * 87.117

C(metal) = -72899.51 / 55780.296 = 1.307

The specific heat capacity of the metal is 1.307 J/g °C
