Answer:

4.61 atm

Explanation:

This question seeks to test our knowledge on conversion of millimeter of mercury (mmHg) to atmospheric pressure (atm).

The numeric relationship between mmHg and atm is given below

1 atm ⇒ 760 mmHg, hence

X atm ⇒ 3,506 mmHg (where X is the unknown)

If you cross multiply the above, you will have

X = $\frac{3,506 * 1}{760}$

X = 4.61 atm

Thus, 4.61 atm is the atmospheric pressure of the gas exerted on the cylinder

Converting between atmospheres and millimeters of mercury. One atm. equals 760.0 mm Hg, so there will be a multiplication or division based on the direction of the change. Solution: multiply the atm value by 760.0 mmHg / atm.
answer=
$3506 \div 760 = 4.6746 \: atm$

Balance the following equations. Do not include the states of matter.<br><br> (a) C + O2 → CO

krek1111 [17]

Answer:

C + O2 → CO2

Explanation:

C + O2 → CO ----------------- (1)

from equ (1) on reactant side, C has 1 mole, O has 2 moles

from equ (1) on product side, C has 1 mole, O has 1 mole

Thus, to balance the equation, O should have 2 moles

C + O2 → CO2

The percent of remaining parent isotope in a radioactive decay process is 40 percent. How many half-lives have elapsed since the

muminat

Answer: Between 1 and 2.

Explanation:

Half life is the amount of time taken by a radioactive material to decay to half of its original value.

$a=\frac{a_o}{2^n}$ ............(1)

where,

a = amount of reactant left after n-half lives = 40

$a_o$ = Initial amount of the reactant = 100

n = number of half lives

Putting in the values we get:

$40=\frac{100}{2^n}$

$2^n=2.5$

taking log on both sides

$nlog(2)=log(2.5)$

$n=1.32$

Thus half-lives that have elapsed is between 1 and 2

Insulin is a protein that is used by the body to regulate both carbohydrate and fat metabolism. A bottle contains 375 mL of insu

Kitty [74]

Mass = Density × Volume
= 30.0 mg / mL × 375 mL
= 11250 mg
= 11.25 g

∴ the total mass of insulin in the bottle is 11.25 g (11250 mg)

A gas occupies 547 L at 331K. Find its volume at 376K. You must show all of your work to receive credit. Also, name the gas law

zysi [14]

621.4L

Explanation:

Given parameters:

Initial volume = 547L

Initial temperature = 331K

Final temperature = 376K

Unknown:

Final volume = ?

Solution:

The appropriate gas law to use is the Charles's law.

The Charles's law shows the relationship between the volume and temperature of a gas under constant pressure.

The law states that "The volume of a fixed of a gas varies directly as its absolute temperature if the pressure is constant".

Mathematically;

$\frac{V_{1} }{T_{1} } = \frac{V_{2} }{T_{2} }$

V₁ is the initial volume

T₁ is the initial temperature

V₂ is the final volume

T₂ is the final temperature

Since the unknown is the final volume, we make it the subject of the expression;

V₂ = $\frac{V_{1} }{T_{1} } x T_{2} = \frac{547}{331 } x 376$

V₂ = 621.4L
