<span>The wavelength (in nm) of radiation that has an energy content of 3.85 x10^3 kJ/mol is 5.16 </span>×<span> 10</span>⁻²³ nm.<span>
</span>
Below, how the answer was derived is attached;  note that C = speed of light, λ= wavelength, E= energy & h = Plank's Constant.

Suppose you need to prepare 136.9 mL of a 0.315 M aqueous solution of NaCl.
Varvara68 [4.7K]

Answer:

2.52 g NaCl

Explanation:

(Step 1)

To find the mass, you first need to find the moles NaCl. This value can be found using the molarity ratio:

Molarity = moles / volume (L)

After you convert mL to L, you can plug the given values into the equation and simplify to find moles.

136.9 mL / 1,000 = 0.1369 L

Molarity = moles / volume

0.315 M = moles / 0.1369 L

0.0431 = moles

(Step 2)

Now, you can use the molar mass to convert moles to grams.

Molar Mass (NaCl): 22.990 g/mol + 35.453 g/mol

Molar Mass (NaCl): 58.443 g/mol

0.0431 moles NaCl           58.443 g
------------------------------  x  -------------------  =  2.52 g NaCl
                                            1 mole

Which of the halide ions (f−, cl−, br−, and i−) is the most stable base? which is the least stable base?
Nezavi [6.7K]
You should take note that the question is about stability. A compound is stable if it does not easily react with other elements. Hence, its reactivity must be low. As you move down the group, reactivity decreases. So, the halide at the very bottom is the least reactive. It would then be logical that the most stable conjugate base is I⁻ and the least stable conjugate base is the most reactive which is F⁻.

Answer: here is a description of what they look like since I cannot see the diagram.

Mitochondria- wavy line

Ribosomes- little dots

Chromosome- X

Nucleus- Circle with bite taken out of it

Endoplasm- Bubble

Nuclear membrane- Outer layer/bubble

Golgi-wavy circle thing

Vacuole- Bigger circle (but not nucleus)

Cytoplasm- its the jelly on the inside

Cell wall- only in plant cells, looks like a box

Cell membrane- The outmost part of the animal cell, the barrier.

I sure hope this helps!!!

A 54-kg jogger is running at a rate of 3 m/s. What is the kinetic energy of the jogger
Phantasy [73]
Kinetic energy = 1/2mv²
where m = 54kg
and v =3m/s
k.e = 1/2×54×3×3
= 1/2×54×9
= 1/2×426
= 486÷2
= 243J
