Marshall determines that a gas has a gage pressure of 276 kPa. What's the absolute pressure of this gas? A. 326 kPa
B. 156 kPa
C. 376 kPa
D. 176 kPa

Answers

Answer: The absolute pressure is 376 kPa.

Explanation :

The absolute pressure of a gas is defined as the sum of gauge pressure and the atmospheric pressure.

We know that the atmospheric pressure of a gas is 101.3 kPa.

So, Absolute pressure becomes 276 kPa + 101.3 kPa = 377.3 kPa

Approximately it can be written as, 376 kPa.

So, the correct option is (C) " 376 kPa ".

Hence, this is the required solution.

C.... 376 tbh just took the test and was right

What mass precipitate will form of 1.50 L of highly concentrated Pb(Clo3)2 is mixed with 0.300 L of 0.110 M NaI

Answers

Given:

1.50 L of highly concentrated Pb(Clo3)2

0.300 L of 0.110 M NaI

Required:

mass precipitate of highly concentrated Pb(Clo3)2

Solution:

M1V1 = M2V2

M1(1.50 L of highly concentrated Pb(Clo3)2) = (0.300 L)(0.110 M NaI)

M1 = 0.022M Pb(Clo3)2 = 0.022 mol/L Pb(Clo3)2

Molar mass of Pb(Clo3)2= 374.2 g/mol

Mass of Pb(Clo3)2 = (0.022 mol/L Pb(Clo3)2)( 1.50 L)( 374.2 g/mol) = 12.35g Pb(Clo3)2

Gases, fluids, and other solids in contact with a moving object will produce ____ due to friction.

Answers

Gases, fluids, and other solids in contact with a moving object will produce heat due to friction. The contact between molecules or atoms present in gases, fluids, and other solids creates energy and it may be in the form of heat.

The answer is: Heat flow

Given 16.2 grams of substance Y, if the substance absorbs 2722 joules of energy and the specific heat of the substance is 9.22 J/g·°C, what is the final temperature of the substance if the initial was 26 degrees Celsius?

Answers

Since the substance absorbs heat, it is expected that the temperature will rise. The formula for the internal energy of a substance is given by the equation:

ΔU = mCpΔT

where:

ΔU = internal energy
m = mass of substance
Cp = specific heat capacity of substance
ΔT = change in temperature

ΔU = 2722 Joules = 16.2 grams (9.22 J/g-°C) (Tf - 26°C)

This gives a final temperature of Tf = 44.22 °C

A solution that is a 4 on pH scale is a

Answers

a pH scale runs from 1 to 14 with 7 being neutral.

1-6 has base like properties
8-14 has avid line properties

since this solution has a pH scale of 4.... the solution is basic

A solution that is 4 on pH scale is an acid. A pH scale is used to measure whether a solution is an acid or a base. the pH scale is numbered between 0 to 14. 7 is the neutral point of this scale. Any solution having a pH of 7 is a neutral solution. Acidity of a solution increases as the reading in the scale decreases from seven towards zero. The basic nature of the solution increases as the pH level of the solution increases from 7 towards 14. The acidic nature of a solution having pH value of 3 is ten times more acidic than a solution having pH value of 4. The same thing is same while comparing basic solutions as well.
