Answer:

$a=\frac{f}{d-e}-\frac{b}{c}$

Explanation:

Hello.

In this case, for the equation:

$(a+b/c)(d-e)=f$

For isolating a, we must first pass (d-e) to divide at the other side as it is initially multiplying:

$a+b/c=\frac{f}{(d-e)}$

Next, as b/c is adding, it passes to subtract at the other side in order to finally isolate a:

$a=\frac{f}{d-e}-\frac{b}{c}$

Best regards!

Allushta [10]

Answer:

Cl⁻, Na⁺, OH⁻

Explanation:

The titration is:

CuCl₂(aq) + 2 NaOH(aq) → Cu(OH)₂(s) + 2 NaCl(aq)

In solution, before the reaction, the ions are Cu²⁺ and Cl⁻. The addition of NaOH (Na⁺ + OH⁻) produce the precipitation of Cu²⁺ forming Cu(OH)₂(s). When you reach the equivalence point, there is no Cu²⁺ because precipitates completely. All OH⁻ ions reacts when are added but when Cu²⁺ is finished, excess OH⁻ ions still in solution helping to detect the equivalence point.

Thus, ions present after the equivalence point are:<em> Cl⁻, Na⁺</em> (Don't react, spectator ions), and <em>OH⁻</em>.

students used a balance and a graduated cylinder to collect the data shown in table 7. calculate the density of the sample. if t

Licemer1 [7]

Answer:

Percentage error = 1.88 %

Solution:

Data Given:

Mass of Sample = 20.46 g

Volume of Sample = 43.0 mL - 40.0 mL = 3.0 mL

Formula Used:

Density = Mass / Volume

Putting values,

Density = 20.46 g / 3.0 mL

Density = 6.82 g.mL⁻¹

Percentage Error:

Experimental Value = 6.82 g.mL⁻¹

Accepted Value = 6.95 g.mL⁻¹

= 6.82 g.mL⁻¹ / 6.95 g.mL⁻¹ × 100 = 98.12 %

Percentage Error = 100 % - 98.12 %

Percentage error = 1.88 %

A balloon vendor at a street fair is using a tank of helium to fill her balloons. The tank has a volume of 124.0 L and a pressur

amm1812

Answer:

She lost 50.88 moles

Explanation:

Step 1: Data given

The volume of the tank = 124.0 L

The initial pressure = 104.0 atm

The temperature = 24.0 °C = 297 K

The pressure drops to 94.0 atm

The temperature stays constant at 297 K

Step 2: Calculate the initial number of moles

p*V = n*R*T

n = (p*V)/(R*T)

⇒with p = the initial pressure = 104.0 atm

⇒with V = the initial volume = 124.0 L

⇒with n = the initial number of moles = TO BE DETERMINED

⇒with R = the gas constant = 0.08206 L*atm/mol*K

⇒ with T = the temperature= 297 K

n = (104.0*124.0)/(0.08206*297)

n = 529.14 moles

Step 3: Calculate final number of moles

p*V = n*R*T

n = (p*V)/(R*T)

⇒with p = the initial pressure = 94.0 atm

⇒with V = the initial volume = 124.0 L

⇒with n = the initial number of moles = TO BE DETERMINED

⇒with R = the gas constant = 0.08206 L*atm/mol*K

⇒ with T = the temperature= 297 K

n = (94.0*124.0)/(0.08206*297)

n = 478.26 moles

Step 4: Calculate the difference of moles

529.14 moles - 478.26 moles = 50.88 moles

She lost 50.88 moles
