Describe the De Borglie's hypothesis​
Advocard [28]

Answer:

The De Broglie hypothesis proposes that all matter exhibits wave-like properties and relates the observed wavelength of matter to its momentum. After Albert Einstein's photon theory became accepted, the question became whether this was true only for light or whether material objects also exhibited wave-like behavior.

How many moles of hydrogen are needed to produce 8 moles of methane CH4? C + H2-> CH4
Lapatulllka [165]

Answer:

20 mol H₂

General Formulas and Concepts:

<u>Chem</u>

  • Stoichiometry

Explanation:

<u>Step 1: Define</u>

RxN: C + H₂ → CH₄

8 moles CH₄

<u>Step 2: Balance RxN</u>

C + 2H₂ → CH₄

<u />

<u>Step 3: Stoichiometry</u>

8 \ mol \ CH_4(\frac{2 \ mol \ H_2}{1 \ mol \ CH_4} ) = 16 mol H₂

<u>Step 4: Check</u>

<em>We are given 1 sig fig. Follow sig fig rules.</em>

16 mol H₂ ≈ 20 mol H₂

A given mass of oxygen at room temperature occupies a volume of 500.0 ml at 1.50 atm pressure. what pressure must be applied to
givi [52]
Boyle's law gives the relationship between pressure of a gas and volume.
It states that the pressure of a gas is inversely proportional to volume of gas at a constant temperature.
PV = k
where P - pressure , V - volume and k - constant 
P1V1 = P2V2 
where parameters for the first instance are on the left side of the equation and parameters for the second instance are on the right side of the equation.
1.50 atm x 500.0 mL = P x 150.0 mL 
P = 5 atm
applied pressure should be 5 atm to compress the gas.

Histamines are an important chemical in the body . what is their purpose in the immune system
pentagon [3]

Answer:

Histamine is a protein produced by <u>mast cells</u> in the body. It plays a very important role in the immune system of the body. Histamine is released in the body when <u>affected by an allergen</u>, e.g, pollen or animal dander. The immune system of the body will respond to such allergen by <u>making more mucus in the nose by releasing histamine</u>. There will be sneezing, itching, coughing and runny nose in response. This is a <u>basic defense of the body's immune system</u> to not enter any particle inside the body.

How can you experimentally determine the solubility of a solute in water at a certain temperature?
Veronika [31]
The solubility of a given solute in a given solvent typically depends on temperature. Many salts show a large increase in solubility with temperature. ... A few, such as cerium(III) sulfate, become less soluble in water as temperature increases.
