Answer:

14.44

Explanation:

Answer:

14.44

Explanation:

If you take a pencil and do the math on paper you will get 14.44 :)

Answer:X-64 is closer to the atomic mass of 64.32 amu. The one on the periodic table is the isotope most common in nature.

Explanation:

The average atomic mass of an  element can be calculated from the percentage abundance and atomic masses of its isotopes. The atomic mass of the element is 64.32 amu which is near to the mass of X-64. Thus the percentage abundance of X-64 will be greater.

Isotopes are atoms of same atomic number and different mass numbers. There many elements which are having both stable and unstable isotopes. The unstable isotopes may undergo radioactive decay and forms a new stable isotope.

Let the fraction of abundance of X-64 be x and the that of X-65 is 1-x. Since total is 100%. Now,

64 (x) + 65 (1-x) = 64.32

x = 0.68.

Thus percentage abundance of X-64 is 68 % and that of X-65 is 100 - 68 = 32 %.

Therefore, the percentage abundance of the element X with isotopes X-64 is having greater abundance.

Explanation:

Answer:

Hard parts of the organism must dissolve

Answer:

3.10×10¯⁵ ft³.

Explanation:

The following data were obtained from the question:

Density (D) of lead = 11.4 g/cm³

Mass (m) of lead = 10 g

Volume (V) of lead =.?

Density (D) = mass (m) / Volume (V)

D = m/V

11.4 = 10 / V

Cross multiply

11.4 × V = 10

Divide both side by 11.4

V = 10 / 11.4

V = 0.877 cm³

Finally, we shall convert 0.877 cm³ to ft³. This can be obtained as follow:

1 cm³ = 3.531×10¯⁵ ft³

Therefore,

0.877 cm³ = 0.877 cm³ × 3.531×10¯⁵ ft³ /1 cm³

0.877 cm³ = 3.10×10¯⁵ ft³

Thus, 0.877 cm³ is equivalent to 3.10×10¯⁵ ft³.

Therefore, the volume of the lead in ft³ is 3.10×10¯⁵ ft³.

Dust storms and desertification

Explanation:

Answer:

27g N2

Explanation:

The elements with standard temperature ,pressure, are the diatomic molecules like hydrogen, nitrogen, chlorine and oxygen.

Two atoms are chemically linked in order to create diatomic molecules. They make up a homonuclear diatomic molecule if the two atoms are the same, such in the oxygen molecule (O2), for example in the case. If the atoms are different.

Diatomic molecules are two-atom-only molecules, which can contain the same or different chemical components. A diatomic molecule is a structure made up of two atoms that were already connected together. Examples include carbon monoxide, oxygen, nitrogen, and hydrogen (H2) (CO).

Thus, hydrogen, oxygen, nitrogen are the element exists as a diatomic molecule at STP.

answer

The beach ball will go the farthest because it's the lightest.

The tennis ball will go second farthest because it is the second lightest.

The baseball will go the third farthest because it is th third lightest'

The bowling ball will go the least far because it is the last farthest  

From the given data chart, the way the mass of each ball affects its motion is that;

The highest mass will have the slowest motion while the least mass will have the fastest motion.

We are given;

Mass of baseball = 400 g

Mass of bowling ball = 900 g

Mass of beach ball = 10 g

Mass of tennis ball = 60 g

Now, according to Newton's first law of motion, the greater the mass of an object, the greater the inertia. This means that objects of higher mass would travel at slower motion than objects of lower mass because objects of higher mass would possess greater inertia.

Thus, looking at the masses of the objects given, the highest mass is 900g which is the mass of the bowling ball. Thus, it will be the slowest.

Next is baseball with 400g which is the third fastest motion.

Next is tennis ball with 60 g which is the second fastest motion

Next is beach ball with 10 g which is the fastest motion.

Answer:

D) Covalent Bonds

Explanation:

Quizlet says so

Among the given options the intramolecular force is covalent bonding. Covalent bond is formed between two nonmetals by sharing of electrons. All other given forces are intermolecular.

A covalent bond is formed between two non-metals through sharing of valence electrons between atoms. For example carbon and oxygen are non metals forming the covalent compound CO.

The number of shared pair of electron depends on the valence of each atoms. For example in HCl, both atoms shares one electron to each other.

In a covalent compound, if the difference in electronegativity between two atoms is significant, the shared pair of electrons attracts towards the highly electronegative atom and resulting charge separation make them polar compounds.
