What are the functions of ammonia in the solvay process​
enot [183]
The ammonia gas is absorbed in the concentrated brine to produce aqueous sodium chloride and aqueous ammonia. This ammoniation process is exothermic, so energy is released as heat. The ammonia tower eventually needs to be cooled.

An extra-strength aspirin contains 0.500 g of aspirin. how many grains is this? (1grain=64.8mg)
Snowcat [4.5K]

By unit conversion, the aspirin contains 7.72 grains.

We need to know about unit conversion to solve this problem. The unit conversion can be used to convert a unit to another unit. It can be defined as

a = xb

where a is unit a, b is unit b and x is the constant of conversion.

From the question above, we know that

m = 0.5 gram

unit conversion

(1 grain = 64.8 mg)

Convert the unit conversion to 1 mg

1 grain = 64.8 mg

1/64.8 grain = 64.8/64.8 mg

1 mg = 1/64.8 grain

Convert the aspirin mass to grain

m = 0.500 g

m = 0.5 x 10³ mg

m = 0.5 x 10³ x 1/64.8 grain

m = 7.72 grain

You wash dishes for a chemistry laboratory to make extra money for laundry. You earn 12 dollars/hour, and each shift lasts 75 mi
nadezda [96]

Answer:

A)You must work 2 shifts to wash 10 loads of laundry

B)You can wash 15 loads pf laundry if you work for 3 shifts

C) each shift will pay for 3.75 loads of laundry if the cost per load rises to 16 quarters

Explanation:

Given:

amount  earned =   12 dollars/hour

Duration for one shift = 75 minutes

Amount needed for Laundry = 12 quarters/load.

A. How many shifts must you work if you wish to wash 10 loads of laundry

To wash 10 loads, you will be requiring

=> 10 \times 12 \text{quarters}

=> 120 quarters

1 quarter = 0.25 dollars---------------------------------(1)

120 quarters

= 120 \times 0.25 \text{ dollars}

= 30 dollars

You need 30 dollars for washing 10 loads

In one hour i,e 60 minutes you earn=  12 dollars

In one minute the amount earned will be

= \frac {12}{60}

= 0.2 dollar-------------------------------------------------------(2)

Now to earn 30 dollars you have to work for

=30 \times 0.2 minutes

= 150 minutes

Thus the number of shifts will be  

= \frac{150}{75}

= 2 shifts

B. How many loads of laundry can you wash if you work 3 shifts

We Know that 1 shift =  75 minutes

So 3 shifts = 75 \times 3 = 225 minutes

From (2),

In 1 minute = 0.2 dollars is earned

So in  225 minutes =  225 \ times 0.2 = 45 dollar is earned

45 dollar = 45 \times 4 = 180 quarters

You can wash 1 load with 12 quarters

With 180 quarters you can wash = \frac{180}{12} = 15 loads

C. How many loads of laundry will each shift pay for if the cost per load rises to 16 quarters

Cost per load = 16 quarters

From (1)

16 quarters = 0.25 \times 16  = 4 dollars per load

From (2) In 1 shift the amount earned will be

=> 75 \times 0.2

=15 dollars

With 4 dollars you can wash 1 load

So with 15 dollars = \frac{15}{4} = 3.75 loads

Marshall determines that a gas has a gauge pressure of 276 kpa what's the absolute pressure of the gas
omeli [17]
A gauge records the pressure over atmospheric pressure (0kpa on the gauge is actually the atmospheric pressure and a reading of 276kpa is 276kpa over atmospheric pressure). That means that means that to find absolute pressure you just add atmospheric pressure (around 1atm (101kpa)) to 286kpa to get 387kpa. I hope this helps.
