Answer:

Approximately two elements may combine to form compounds, but there may be cases where more than two elements combine to form compounds.

Explanation:

In chemistry, the term compound is defined as a substance formed by the union of at least two elements. There are cases where more than two elements come together to form a compound, but we can say that approximately two elements are used for compound formation. An example of compound is shown in the chemical formulas H2O and FeS represent the compounds water and ferrous sulfide.

uppose you are titrating an acid of unknown concentration with a standardized base. At the beginning of the titration, you read
sweet-ann [11.9K]

Answer:

V_{base}=18.00mL

Explanation:

Hello,

In this case, since you have both the final and initial volume for the titration procedure, clearly, the used volume is computed by the subtraction between them, since it accounts for the employed volume of the base, it turns out:

V_{base}=20.03mL-2.03mL\\\\V_{base}=18.00mL

Best regards.

A certain shade of blue has a frequency of 7.17 × 1014 hz. what is the energy of exactly one photon of this light?
-Dominant- [34]
Answer is: the energy of exactly one photon of this light is 4.75·10⁻¹⁹ J.
Photon energy equation: E = h·ν.
E - energy of one photon.
ν- frequency.
h - Planck's constant.
ν = 7.17·10¹⁴ Hz.
h = 6.63·10⁻³⁴ J·s.
E = 6.63·10⁻³⁴ J·s · 7.17·10¹⁴ Hz.
E = 4.75·10⁻¹⁹ J.
