Answer:

The increasing order of the ability to cause harm to living tissue:

Weapons  < Television tubes < Nuclear medicine < Cosmic radiation <Ground < Diagnostic X rays < Air (radon-222)

Explanation:

Here, the ability of the radiation to harm living tissue is measured in terms of millirem

Unit conversion:

1\ millirem = \frac{1}{1000}\  rem = 0.001\ rem\\\\or,\ 1\ rem = 1000\ millirem

The given radiation doses can be converted into units of millirems for comparison:

Weapons test fallout = 1 millirem

Cosmic radiation = 26 millirems

Air (radon-222) =  0.198 rems  = 198 millirems

Diagnostic X rays =  0.040 rems  = 40 millirems

Television tubes = 11 millirems

Nuclear medicine =  0.015 rems  = 15 millirem

Ground = 33 millirems

Since a greater dosage of radiation would lead to greater risk, the increasing order of their ability to cause harm to living tissue would be:

Weapons  < Television tubes < Nuclear medicine < Cosmic radiation <Ground < Diagnostic X rays < Air (radon-222)

Use the bond energy to calculate an approximate value of δh for the following reaction. Which is the more stable form of fno2?
professor190 [17]

The enthalpy of reaction or ∆H reaction is the difference between the bond energy of the reactants and the bond energy of the products.

<h3>What is ∆H reaction?</h3>

The term ∆H reaction refers to the heat that is evolved or absorbed in a chemical reaction. It is also known as the enthalpy of reaction.

The question is incoherent but I will try to answer as much as possible. Using the values of bond energy, ∆H reaction = Bond energy of reactants - bond energy of products. This will give us the enthalpy of reaction.

Write the formula of the conjugate base of the Brønsted-Lowry acic, HF​
alexdok [17]

Answer:

Furthermore, because hydrofluoric acid, HF, loses a proton, H+1, to generate its conjugate in the reaction that is shown above, this reactant can be classified as a Brønsted-Lowry acid, and, consequently, the fluoride ion, F–1, is the conjugate base of this acid.

Explanation:

How many grams of MgCl2 would be needed to make 5.3 liters of a 0.25 molar solution? Round your answer to the nearest 0.01,
GuDViN [60]

Answer: 126.1 grams of are needed to make 5.3 L of 0.25 M solution

Explanation:

Molarity of a solution is defined as the number of moles of solute dissolved per liter of the solution.

To calculate the mass of solute for given molarity, we use the equation:

\text{Molarity of the solution}=\frac{\text{given mass of solute}}{\text {Molar mass of solute}\times \text{Volume of solution in L}}

0.25M=\frac{x}{95.2g/mol\times 5.3L}

x=126.1g

Thus 126.1 grams of are needed to make 5.3 L of 0.25 M solution

solution:

Hydration is the addition of water; hydrogenation is the addition of hydrogen.  

desire rxn: _C4H6(g) + 2 H2(g)-----> C4H10(g)___dHhy = ??  

knowns:  

__________C4H6 + 11/2 O2 --------> 4CO2 + 3H2O______dHox = -2540.2 kJ/mole  

__________4CO2 + 5H2O -----------> C4H10 + 13/2 O2___-dHox = 2877.6 kJ/mole  

___________2(1/2 O2 + H2 -------------> H2O)___________2*dHox = 2(-285.8 kJ/mole)
