How many molecules are in 9.8 grams of calcium

Answers

Hmm
One mole of calcium is usually equal to 40 grams so divide 9.8 by 40 which would be 4.0 molecules

certain solution has [OH-] = 4 x 10-3. Calculate the concentration of [H3O+] and the pH of the solution

Answers

Kw = 1 x 10⁻¹⁴

Kw = [ H₃O⁺] [ OH⁻]

1 x 10⁻¹⁴ = [ H₃O⁺] * 4 x 10⁻³

[H₃O⁺] = 1 x 10⁻¹⁴ / 4 x 10⁻³

[H₃O⁺] = 2.5 x 10⁻¹² M

The step that usually comes last in solving numeric problems is to ___

Answers

Answer:

The step that usually comes last in solving numeric problem is to evaluate.

Explanation:

First step is Analyze .

Second is Calculating .

Third is Evaluate .

Analyze : To solve a word problem, you must first determine where you are starting from and where you are going . Then you decide whether you know the answer or you don't know it . After that you make plan for getting from unknown to known.

Calculation : After analyzing , you need to do calculation . For some problem you need to convert one unit into other or may you need to rearrange an equation. Calculation is the easiest part.

Evaluation : After calculation , you need to evaluate whether the answer is reasonable or not? Does it make sense?Did you choose the right equation ?

It helps to round off the numbers and make an estimate of the answer.

the answer is evaluate. The 3 steps are, analyze, calculate, evaluate.

Atomic emission spectra are produced when the light emitted by an element passes through a prism. Which of the following statements is true regarding these spectra?A. All elements produce the same atomic spectra.
B. Elements produce continuous spectra.
C. Elements produce spectra with only a few distinct lines.

Answers

Option C: elements produce spectra with only few distinct lines.

The spectra are not continuos and are different for every element. This permits to identify elements.

Final answer:

Atomic emission spectra are unique to each element and consist of distinct lines representing different energy levels.

Explanation:

The correct statement regarding atomic emission spectra is option C: Elements produce spectra with only a few distinct lines.

The spectra produced by different elements are unique to each element, meaning that they have distinct patterns of lines.
These lines represent the different energy levels that electrons can occupy within the atom.
The specific pattern of lines in an atomic emission spectrum can be used to identify the element present in a sample of unknown composition.

The process that ice on mount Everest goes through when heated from 10 degree f to 305 kelvin.

Answers

water melts at 32 F and boils at 212 F
if we change these values into Kelvin then
melting point of water is 273.15 K and boiling point is 373.15 kelvin..
for melting it is necessary for ice to get warm so it attains heat 10 F to 32 F...
then ice melts but during this temperature remains constant..
the energy required for melting is 333 kJ/Kg K
then water is warmed at 305 Kelvin.... :)
