Convert everything to one base unit (let's do ft/s in this case)
There are 660 ft in a furlong and 2 weeks or 1209600 seconds in a fortnight
Multiply 537,600furlong and 660 ft/furlong and divide by 1209600 to get 293.333ft/s

The race car is already in ft/s

There are 30.48 cm in 1 foot and 3600 seconds in 1 hour.  Multiply 9,000,000 by 1/30.48 and 1/3600 to get 82.02ft/s

THe peregrine falcon is the fastest

Complete Question

The complete question is shown on the first uploaded image

Answer:

The calculation and filling of the table based on the ratio indicated by the column is shown on the second uploaded image

1 This is True

2 This is False

3 This is False

4 This is  True

5 This is  True

Explanation:

Based on your calculations, indicate whether each statement is True (T) or False (F):

Considering the first statement

Looking at the question we can see that the first statement is TRUE this because  all the three experiment have different initial concentration (3.5,3.0 & 2.6)

Considering the second  statement

 Looking at table we can see that the second statement is FALSE  because  

the ratio value of [NO2]/ [N2O4] in all three experiment have different value  1.4 , 1.5 & 1.7 is not a constant value.

Considering the Third  statement

Looking at the table we can see that the third statement is FALSE this  is because the ratio value of 2[NO2]/ [N2O4] in all three experiment have different value 2.7, 3.0 & 3.3 is not a constant value.

Considering the Fourth  statement

Looking at table we can see that the fourth statement is TRUE this is because the ratio value of[NO2]^{2}/ [N2O4] in all three experiment have same value 3.9, 3.9 & 3.9 is a constant value.

Considering the Fifth  statement

Looking at table we can see that the fifth statement is TRUE this is because

each having different set of Equilibrium concentration

1. A helium-filled balloon had a volume of 8.50 L on the ground at 20.0°C and a
maw [93]

Answer:

133.74 L

Explanation:

First we <u>convert the given pressures and temperatures into atm and K</u>, respectively:

  • 750.0 Torr ⇒ 750/760 = 0.9868 atm
  • 20°C ⇒ 20+273.16 = 293.16 K
  • 40°C ⇒ 40+273.16 = 313.16 K

Then we<u> use the PV=nRT formula to calculate the number of moles of helium in the balloon</u>, using<em> the data of when it was on the ground</em>:

  • 0.9868 atm * 8.50 L = n * 0.082 atm·L·mol⁻¹·K⁻¹ * 293.16 K
  • n = 2.866 mol

Then, knowing the value of n, we <u>use PV=nRT once again, this time to calculate V</u> using <em>the data of when the balloon was high up:</em>

  • 0.550 atm * V = 2.866 mol * 0.082 atm·L·mol⁻¹·K⁻¹ * 313.16 K
  • V = 133.74 L

How would poisoning proton pumps impact anion uptake? see section 36.3 ( page 755) ?
boyakko [2]
The answer to this question would be: the anion uptake will be decreased

If proton pump function is decreased, that means the amount of proton that goes outside the cell will be decreased. It will cause the anion uptake decreased too because some anion needs to go inside cells by co transporting with the proton.

Is Ca-Ci a covalent or ionic bond and why?
taurus [48]

Ionic bond

Explanation:

Ca - Cl₂ is an ionic bond because it involves a true metal and a non-metal.

An ionic bond is an inter-atomic bond between two chemical species.

  • This bond forms between two atom with a large electronegative difference.
  • Often times, this corresponds to a metal and a non-metal.
  • The metal is the less electronegative specie and the non-metal is more electronegative
  • The metal such as Ca loses two electrons to become positively charge ion.
  • The non-metal gains the electrons. Here two atoms of Cl are turned to ions.
  • Electrostatic attraction between the metal and non-metal forms the ionic bonding.
