Chemistry
1 answer:
Y_Kistochka [10]3 years ago
4 0

Answer :

(a) The 60 feet of water is equal to 179344.2 Pa.

(b) The 220 psi is equal to 31680lbf/ft^2

(c) The 120 torr is equal to 15998.6 Pa.

(d) The 1.0 atm to inches of glycerin  is equal to 323.07 inches.

(e) The 1050 mm Hg is equal to 376.95lbf/ft^2

Explanation :

(a) The conversion used from feet to pascal is:

1\text{ feet}=2989.07Pa

As we are given that 60 feet of water. Now we have to convert into Pa.

As, 1\text{ feet}=2989.07Pa

So, 60\text{ feet}=\frac{60\text{ feet}}{1\text{ feet}}\times 2989.07Pa=179344.2Pa

The 60 feet of water is equal to 179344.2 Pa.

(b) The conversion used from psi to lbf/ft^2 is:

1\text{ psi}=144lbf/ft^2

As we are given that 220 psi. Now we have to convert into lbf/ft^2.

As, 1\text{ psi}=144lbf/ft^2

So, 220\text{ psi}=\frac{220\text{ psi}}{1\text{ psi}}\times 144lbf/ft^2=31680lbf/ft^2

The 220 psi is equal to 31680lbf/ft^2

(c) The conversion used from torr to pascal is:

1\text{ torr}=133.322Pa

As we are given that 120 torr. Now we have to convert into Pa.

As, 1\text{ torr}=133.322Pa

So, 120\text{ torr}=\frac{120\text{ torr}}{1\text{ torr}}\times 133.322Pa=15998.6Pa

The 120 torr is equal to 15998.6 Pa.

(d) 1.0 atm to inches of glycerin

Formula used : P=\rho gh

where,

P = pressure of glycerin = 1.0 atm = 101325 Pa

g = acceleration due to gravity = 9.8m/s^2

\rho = density of glycerin = 1260kg/m^3

Now put all the given values in above formula, we get:

101325Pa=(1260kg/m^3)\times (9.8m/s^2)\times h

h=8.206\frac{Pa.m^2s^2}{kg}=8.206m=323.07\text{ inches}

Conversion used :

1Pa=\frac{kg}{ms^2}\\\\1m=39.37inches

The 1.0 atm to inches of glycerin  is equal to 323.07 inches.

(e) The conversion used from psi to lbf/ft^2 is:

1\text{ mmHg}=0.359lbf/ft^2

As we are given that 1050 mmHg. Now we have to convert into lbf/ft^2.

As, 1\text{ mmHg}=0.359lbf/ft^2

So, 1050\text{ mmHg}=\frac{1050\text{ mmHg}}{1\text{ mmHg}}\times 0.359lbf/ft^2=376.95lbf/ft^2

The 1050 mm Hg is equal to 376.95lbf/ft^2

While you were "sweating" your chemistry test, water vapor evaporates from your body, absorbing 50,000 J of energy. (assume no
TiliK225 [7]

Answer:

\boxed {\boxed {\sf B. \ 22 \ grams}}

Explanation:

We need to use the formula for heat of vaporization.

Q=H_{vap}*m

Identify the variables.

  • The heat absorbed by the evaporating water is the <u>latent heat of vaporization. </u>For water, that is 2260 Joules per gram.
  • Q is the energy, in this problem, 50,000 Joules.
  • m is the mass, which is unknown.

H_{vap}=2260 \ J/g\\Q=50,000 \ J \\

Substitute the values into the formula.

50,000 \ J=2260 \ J/g*m

We want to find the mass. We must isolate the variable, m.

m is being multiplied by 2260 J/g. The inverse operation of multiplication is division. Divide both sides by 2260 J/g.

\frac{50,000 \ J}{2260 \ J/g} =\frac{2260 \ J/g*m}{2260 \ J/g}

\frac{50,000 \ J}{2260 \ J/g} =m

Divide. Note that the Joules (J) will cancel each other out.

\frac{50,000 \ }{2260 \ g} =m

22.1238938 \ g =m

Round to the nearest whole number. The 1 in the tenth place tells us to leave the number as is.

22 \ g \approx m

The mass is about 22 grams, so choice B is correct.

What would the molecular formula be if lithium and sulfur reacted to form a neutral compound?
skad [1K]

Answer:

D, Li2S

Explanation:

This is because Lithium, which is in group IA of the periodic table, has a charge of +1. Sulfur will have a charge of -2 because it is in group 6A in the periodic table, which means to balance these out, there needs to be 2 lithium ions which would result in a charge of +2. With Lithium now having a charge of +2 due to having two atoms in the compound, and sulfur already having a charge of -2 as one atom, these two cancel out meaning the compound is neutral.

Why does the pressure inside a container of gas increase?
yan [13]
Pressure is a scientific parameter that allows us to determine the amount of force being exerted per unit area. The increase in the pressure inside a container containing a gas may be brought upon by the decrease in volume, increase in temperature, or merely by additional of more gas molecules.
