The engineering quadrangle is approximately 235 meters above sea level. If the temperature is 15 degrees Celsius, is that above, below, or equal to the standard temperature for this altitude?

The 15 ⁰C measured at this altitude is above the standard temperature for the altitude.

Explanation:

The standard temperature at sea level is 15 degrees Celsius. It decreases about 2 degrees C (or 3.5 degrees F) per 1,000 feet of altitude above sea level.

235 meters is equal to 771 feet.

Using the formula below, we can estimate temperature loss due to this change in altitude, that is 771 feet above sea level.

temperature loss  =  (3.5 x Change in altitude)/1000ft

temperature loss  =  (3.5 x 771ft)/1000ft = 2.7⁰F, (32 -2.7 = 29.3 ⁰F)

this is equivalent to 1.5⁰C temperature loss.

Thus, the standard temperature of the engineering quadrangle at 235 meters above sea level is 13.5 ⁰C.

Therefore, the 15 ⁰C measured at this altitude is above the standard temperature for the altitude.

  1.the balanced   chemical equation is as below

cu +   2 ag(no)₃ → cu(no₃)₂   +2 ag

2.the   much silver   produced   is   50.9 g

step 1: find the   moles of cu

moles =   mass÷   molar mass

  from periodic table the molar mass of cu = 63.5 g/mol

moles is therefore = 15.00 g÷ 63.5 g/mol = 0.236   moles

step 2: use the mole ratio to determine the   moles of ag

from equation above   cu: ag   is 1: 2

therefore the moles of ag   =0.236   moles   x 2/1 =0.472   moles

step 3: find the mass   of ag

mass = moles x molar mass

from periodic table   the molar mass of ag =107.87 g/mol

mass   = 0.472   moles x 107.87 g/mol = 50.9 g

3.   the   much   silver   collected worth is   1.797 oz

  convert   50.9 g   to oz

that is   1 gram = 0.0353 oz

          50.9 grams =?   oz

by cross multiplication

={(50.9 grams x 0.0353 oz) / 1   gram}   =1.797 oz

c. 7/3

step-by-step explanation:

a rational number is like pi- it is a repeating decimal.

a. is -1.8

b. 2.236068

c. 2.3333333333333333333

d.   is 3

i hope that ! =)
