Answer:

He had communist friends and family.

Explanation:

Hello,

In this case, it is widely known that Robert Oppenheimer (1904-1967) was a scientist who was part of the Manhattan Project formed to create the atomic bomb. At the Los Alamos laboratory he performed his scientific work in the light of researching and designing the bomb, that is why he is the soc-called father of such bomb. By 1954, the lifeguards he had were removed, he started being investigated as well as his future access to the classified information was revoked since it was dug up he had friends and family supporting and living based on the communism.  

Best regards.

Julius Robert Oppenheimer was an American hypothetical physicist and teacher of material science at the University of California, Berkeley. He was examined and denied future access to grouped data since he had loved ones who had a place with the Communist Party.

What is the formula of a compound if a sample of the compound contains 0.492 mol X, 0.197 mol Y, and 0.295 mol Z?
kozerog [31]

Answer:

X₅Y₂Z₃

Explanation:

The formula of a compound is determined as the whole number ratio between moles of each element present in the molecule.

The molecule is made from X, Y and Z. To fin the ratio we will divide the given moles in the moles of Y (0.197 moles), because is the element with the low number of moles.

X = 0.492 moles / 0.197 moles = 2.5

Y = 0.197 moles / 0.197 moles = 1

Z = 0.295 moles / 0.197 moles = 1.5

But, as the formula is given just with whole numbers, if we multiply each number twice:

X = 2.5*2 = 5

Y = 1*2 = 2

Z = 1.5*2 = 3

The formula is:

<h3>X₅Y₂Z₃</h3>

To identify a diatomic gas (X2), a researcher carried out the following experiment: She weighed an empty 4.6-L bulb, then filled
MakcuM [25]

Answer:

The diatomic gas is probably N2

Explanation:

Step 1: Data given

Volume of the bulb = 4.6 L

Pressure = 1.80 atm

Temperature = 27.0 °C = 300K

Mass of the gas = 9.5 grams

Step 2: Calculate the number of moles

PV=nRT

⇒with P = the pressure of the gas= 1.80 atm

⇒with V = the volume of the gas = 4.6 L

⇒with n = the number of moles gas = TO BE DETERMINED

⇒with R = the gas constant = 0.08206 L*atm/mol*K

⇒with T = the temperature = 300 K

n = (p*V)/(R*T)

n = (1.80 * 4.6) / (0.08206*300)

n = 0.336 moles

Step 3: Calculate molar mass

Molar mass = mass / moles

Molar mass = 9.5 grams / 0.336 moles

Molar mass = 28.3 g/mol

The diatomic gas is probably N2
