2.<span> It's important to know your blood type because it prevents the risk of you receiving an incompatible blood type at a time of need, such as during a blood transfusion or during surgery. If two different blood types are mixed, it may lead to a clumping of blood cells that can be potentially fatal.</span>

Review the table detailing the mass of Jupiter’s moons and their distance from the planet. Which of Jupiter’s moons has the grea
olga nikolaevna [1]

The correct answer is Lo.  

The gravitational force between the two components is directly equivalent to the product of their masses and is inversely proportional to the distance separated between them. The largest planet in the solar system is Jupiter. It comprises 75 moons, and out of these moons, the four Galilean moons are very big in mass. These are Lo, Europa, Ganymede, and Callisto.  

Of these Galilean moons, the Lo moon is very close to Jupiter. The Ganymede moon is the largest of all the Galilean moons, but it is situated very far from Jupiter in comparison to Lo. Thus, the force of attraction between the Lo and Jupiter is very high, it exhibits the greatest gravitational force with Jupiter.

What is the maximum number of hydrogen atoms that can be covalently bonded in a molecule containing two carbon atoms?
inessss [21]
Each carbon atom has 4 elections available for bonding. One of 2 of these are used for the C - C bond so there are 6 available to bond with hydrogen. So maximum number of hydrogen atoms = 6.

Olympic cyclist fill their tires with helium to make them lighter. Calculate the mass of air in an air filled tire and the mass
inn [45]

<u>Answer:</u> The mass difference between the two is 7.38 grams.

<u>Explanation:</u>

To calculate the number of moles, we use the equation given by ideal gas follows:

PV=nRT

where,

P = pressure = 125 psi = 8.50 atm    (Conversion factor:  1 atm = 14.7 psi)

V = Volume = 855 mL = 0.855 L    (Conversion factor:  1 L = 1000 mL)

T = Temperature = 25^oC=[25+273]K=298K

R = Gas constant = 0.0821\text{ L. atm }mol^{-1}K^{-1}

n = number of moles = ?

Putting values in above equation, we get:

8.50atm\times 0.855L=n\times 0.0821\text{ L atm }mol^{-1}K^{-1}\times 298K\\\\n=\frac{8.50\times 0.855}{0.0821\times 298}=0.297mol

To calculate the number of moles, we use the equation:

\text{Number of moles}=\frac{\text{Given mass}}{\text{Molar mass}}      .....(1)

  • <u>For air:</u>

Moles of air = 0.297 moles

Average molar mass of air = 28.8 g/mol

Putting values in equation 1, we get:

0.297mol=\frac{\text{Mass of air}}{28.8g/mol}\\\\\text{Mass of air}=(0.297mol\times 28.8g/mol)=8.56g

Mass of air, m_1 = 8.56 g

  • <u>For helium gas:</u>

Moles of helium = 0.297 moles

Molar mass of helium = 4 g/mol

Putting values in equation 1, we get:

0.297mol=\frac{\text{Mass of helium}}{4g/mol}\\\\\text{Mass of helium}=(0.297mol\times 4g/mol)=1.18g

Mass of helium, m_2 = 1.18 g

Calculating the mass difference between the two:

\Delta m=m_1-m_2

\Delta m=(8.56-1.18)g=7.38g

Hence, the mass difference between the two is 7.38 grams.

A sample of gas occupies a volume of 445 mL at a temperature of 274 K. At what temperature will this sample of gas occupy a volu
Ksenya-84 [330]
V1 = 445ml V2 = 499ml
T1 = 274 K T2 = ?

By Charles Law,
V1/T1 = V2/T2
445/274 = 499/T2
By solving we get,
T2 = 307.25 K
