A container of a mixture of 4 gases has a total pressure of 35.7 kPa. Gas A has a partial pressure of 7.8kPa. Gas B has a partia
Maurinko [17]

Answer:

partial pressure of gas D Pd = 15.5 kPa

Explanation:

As per the Dalton's law of partial pressure, in a mixture, pressure exerted by each gas when summed gives the total partial pressure exerted by mixture.

P(Total) = P1+P2+P3.....

Given P(Total) = 35.7 kPa

Partial pressure of gas A Pa = 7.8 kPa

Partial pressure of gas B Pb = 3.7 kPa

Partial pressure of gas C Pc =  8.7 kPa

There, Partial pressure of gas D Pd = P(Total) -(Pa+Pb+Pc)

Pd = 35.7-(7.8+3.7+8.7) = 35.7-20.2 kPa = 15.5 kPa

Therefore, partial pressure of gas D Pd = 15.5 kPa

Labels of many food products have expiration dates, at which point they are typically removed from the supermarket shelves. A pa
White raven [17]

Answer:

Explanation:

Since it first order, we use order rate equation

In ( \frac{A1}{A0}) = -kt where A1 is the final quality = 0.8 (80%), A0 is the initial quality = 1 ( 100%)

also, t half life = \frac{In2}{k} where k is rate constant

k = \frac{In 2}{45 days} = 0.0154

In ( \frac{0.8}{1}) = - 0.0154 t

-0.223 / -0.0154 = t

t = 14.49 approx 14.5 days from the date the yogurt was packaged

In a can of soda (335 grams of soda ) there are 33g of sugar. What is the mass percent of sugar in soda?
Contact [7]

Answer:

9.85% is the mass percent

Explanation:

Mass percent can be determined as mass of solute in 100 g of solution

The solution is soda

Sugar is the solute

(mass of solute / total mass of solution) . 100 =

(33 g / 335g) . 100 = 9.85%

A 25.0 g sample of metal at
AveGali [126]

The answer to this question is change in temperature will be 6.1 and specific specific heat capacity of metal will be 1698.36.

According to the formula of Calorimetry

Q = msΔT

where, Q = Quantity of heat absorbed (in joules)

M = Mass of water sample given (in kilogram)

S = specific heat capacity of metal

ΔT = Change in temperature

We have given,

Mass as 25 gram which is equal to 0.025 Kg.

Change in temperature as 6.1

Quantity of heat absorbed as 259 J

Applying to the formula of Calorimetry

Q = msΔT

259 = 0.025 × s × 6.1

s = 1698.36

So, specific heat capacity of metal came out to be 1698.36 and the change in temperature will be 6.1
