Americium-241 undergoes fission to produce three neutrons per fission event. if a neutron-absorbing material is mixed in with th

is sample so that the rate of neutron production drops down to 1.8 neutrons per fission event, which will be effective at achieving a critical mass? check all that apply. remove a deflective shield surrounding the sample. remove absorbent material mixed in with the sample. compress the sample of americium-241.

Critical mass can be achieved by compressing the sample of americium-241 and also removing the deflective shield surrounding the sample.

<h3>What is critical mass?</h3>

Critical mass of a nuclear reaction is the mass of nuclear fuel which is just sufficient for a nuclear fission reaction to proceed and be sustained.

In order to achieve critical mass, the density of the fuel is increased by compressing the sample of americium-241 and also remove the deflective shield surrounding the sample.

Draw the alcohol that is the product of the reduction of 3-methylpentanal.
natali 33 [55]

Answer: The product from the reduction reaction is

CH3-CH2-CH(CH3)-CH2-CH2OH

IUPAC name; 3- Methylpentan-1-ol

Explanation:

Since oxidation is simply the addition of oxygen to a compound and reduction is likewise the addition of hydrogen to a compound.

Therefore, hydrogen is added onto the carbon atom adjacent to oxygen in 3- methyl pentanal

CH3 CH2 CHCH3 CH2 CHO thereby -CHO( aldehyde functional group) are reduced to CH2OH ( Primary alcohol) which gives;

3-methylpenta-1-ol .

The structure of the product is:

CH3-CH2-CH(CH3)-CH2-CH2OH

Solve the following question
Andrew [12]

Answer:

140. J/g*K

Explanation:

To find the specific heat capacity, you need to use the following equation:

Q = mcΔT

In this equation,

-----> Q = energy/heat (J)

-----> m = mass (g)

-----> c = specific heat (J/mole*K)

-----> ΔT = change in temperature (K)

Before you can use the equation above, you need to (1) convert kg to grams, then (2) convert grams to moles (via molar mass), and then (3) convert Celsius to Kelvin. The final answer should have 3 significant figures.

1.11 kg C₄H₈O₂ x 1,000 = 1110 g

Molar Mass (C₄H₈O₂): 4(12.01 g/mol) + 8(1.008 g/mol) + 2(16.00 g/mol)

Molar Mass (C₄H₈O₂): 88.104 g/mol

1110 grams C₄H₈O₂                1 mole
------------------------------  x  -------------------------  =  12.6 moles C₄H₈O₂
                                           88.104 grams

34.5 °C + 273 = 307.5 K

52.3 °C + 273 = 325.3 K

Q = mcΔT                                                                   <----- Equation

3.14 x 10⁴ J = (12.6 moles)c(325.3 K - 307.5 K)         <----- Insert values

3.14 x 10⁴ J = (12.6 moles)c(17.8)                                <----- Subtract

3.14 x 10⁴ J = (224.28)c                                 <----- Multiply 12.6 and 17.8

140. = c                                                         <----- Divide both sides by 224.28

**this answer may be slightly off due to using different molar masses/Kelvin conversions**

Differentiate between acids and bases on the basis of their pH values. Give an example of each type. (ANSWER ASAP)
inessss [21]

Acid and bases both are the substances that cause corrosion. They can be differentiated on the basis of properties and pH.

If the pH is less than 7.0 the solution is acidic while if its value is greater than 7.0 it is the basis solution.

Examples:

Acid

Acetic acid has pH value 2.4

Sulphuric acid has pH value 0 for 1M solution

Base

pH of ammonia solution is 11
