Here’s sort of an example/explanation related to that.
Let’s say I have a green sweater and a blue sweater. I can easily throw both inside of a pile and mix them around. But they’re still two different sweaters. Or I can make them a “compound” and use both colors to make one green and blue sweater.

Explain how you were able to use your knowledge of how different types of blood react with anti A, anti B, and anti Rh antibodie
dybincka [34]

Depending upon the clumping reaction with anti A , anti B and anti Rh antibodies the blood types are determined.

Explanation:

Agglutination (clumping) will occur when blood that contains the particular antigen is mixed with the particular antibody.

A+ have Agglutination with Anti-A ,Anti-Rh and No agglutination with Anti-B.

A- have Agglutination with Anti-A and No agglutination with Anti-B and Anti-Rh.

B+ have Agglutination with Anti-B Anti-Rh and No agglutination with Anti-A.

B- have Agglutination with Anti-B and No agglutination with Anti-B and Anti-Rh.

Rh+ have Agglutination with Anti-A and Anti-Rh and No agglutination with Anti-B.

Rh- have No Agglutination with Anti-A and Anti-B and Anti-Rh.

A 750-mL sample of hydrogen exerts a pressure of 822 torr at 325 K. What pressure does it exert if the temperature is raised to
Sunny_sXe [5.5K]

Answer:

1.20 × 10³ torr

Explanation:

Step 1: Given data

  • Initial pressure (P₁): 822 torr
  • Initial temperature (T₁): 325 K
  • Final pressure (P₂): ?
  • Final temperature (T₂): 475 K
  • Constant volume: 750 mL

Step 2: Calculate the final pressure of the gas

Considering the constant volume, if we assume the gas behaves ideally, we can calculate its final pressure using Gay-Lussac's law.

P₁/T₁ = P₂/T₂

P₂ = P₁ × T₂/T₁

P₂ = 822 torr × 475 K/325 K = 1.20 × 10³ torr
