What causes some atoms of the same element to have different atomic masses?

Chemistry
1 answer:
Vladimir79 [104]3 years ago
4 0

Answer: Some atoms of the same elements that have different atomic masses are called isotopes

Explanation:

so the atoms are the same element but different in mass. Since the isotopes have the same number of protons and electrons the isotopes have much the same chemical behavior. Since the isotopes have different numbers of neutrons the nuclear behavior differs.

Draw the structures of the aldol addition and condensation products of 3‑methylbutanal
Leona [35]

Aldol condensation involves  two aldehydes or two ketones or an aldehyde and a ketone. The product of the reaction is shown in the image attached.

<h3>What is Aldol condensation?</h3>

Aldol condensation is a reaction that involves two aldehydes or two ketones or an aldehyde and a ketone. This reaction occurs at the carbonyl group as one of the carbonyl compounds is in the enolate form.

The product of the reaction is shown in the image attached. This gives the mechanism for the Aldol condensation of the compound 3‑methylbutanal.

Calculate the thermometer in an air-conditioned room reads 20.0°C what is the temperature of the room In degrees Fahrenheit and
maks197457 [2]

Answer:

A. 68°F

B. 293K

Explanation:

The temperature (celsius) = 20.0°C

A. Conversion of the temperature in celsius to fahrenheit.

This is illustrated below:

°F = 9C/5 + 32

C = 20°C

°F = 9C/5 + 32

°F = 9x20/5 + 32

°F = 36 + 32

°F = 68°F

B. Temperature (Kelvin) = temperature (celsius) + 273

Temperature (celsius) = 20°C

Temperature (Kelvin) = 20°C + 273

Temperature (Kelvin) = 293K

The pOH of a solution is 6.0. Which statement is correct?
I am Lyosha [343]

Answer : Option D) The pH of the solution is 8.0.

Explanation : pOH of a solution is a measure of hydroxide ion (OH^{-}) concentration in a particular solution. It gives the measure of alkalinity of a solution. Normally, aqueous solutions at 25°C have pOH which is less than 7 are usually alkaline, when pOH is found to be greater than 7 then they are acidic and when pOH will be equal to 7 then it is neutral.

pH + pOH = 14, this relationship is used to find pH of any unknown solution with given pOH value,

Here, we known pOH is 6.0, so we get,

pH = 14 - 6 = 8.0;

Hence, the pH will be 8.0.
