Answer:

Explanation:

Every A will be paired with a T, and every C with a G and vice versa (T to A, and G to C)

So the first letters in the sequence are ATGGG. So the pair will be TACCC.

Why do all atoms of an element have the same atomic number, although they may have different mass numbers?. What do we call atom
3241004551 [841]
The isotopes of an element differ in the number or neutrons whereas the number of protons or electrons of a neutral atom stays the same. The molar mass of the element is based on the percent abundances of different isotopes and the individual molar mass of each isotope.

If you are given only the mass number of neutrons, how do we find an atomic number?
77julia77 [94]

Mass number is the sum of protons and neutrons.

Atomic number is the total number of protons present.

Mass number = protons + neutrons

Atomic number = protons present.

From the above equations we can conclude that,

Atomic number= Mass number- neutrons.

Thus we can find out the atomic number by subtracting the number of neutrons from the mass number.

Which of the following samples will have the lowest pressure if they are all at the same temperature and in identical containers
snow_lady [41]

Answer:

c. 15 g Kr

Explanation:

The amount of a gas (Moles) is directely proportional to its pressure. That means the higher amount of moles, the highest pressure and vice versa.

Using molar mass of the compounds (Ne=20.2g/mol, Ar = 39.9g/mol, Kr = 83.8g/mol, CO₂ = 44 g/mol and F₂ = 38.0g/mol), moles of 15.0g of each gas are:

Ne = 15g ₓ (1mol / 20.2g) = <em>0.74 moles of Ne</em>

Ar = 15g ₓ (1mol / 39.9g) = <em>0.38 moles of Ar</em>

Kr = 15g ₓ (1mol / 83.8g) = <em>0.18 moles of Kr</em>

CO₂ = 15g ₓ (1mol / 44g) = <em>0.34 moles of CO₂</em>

F₂ = 15g ₓ (1mol / 38g) = <em>0.39 moles of F₂</em>

<h3>As 15g of Kr contains the less quantity of moles, this sample will con have the lowest pressure</h3>
