What is the mass of 600.00 mL sample of seawater with a density of 1.025 g/mL?
kvasek [131]

Answer:

<h2>The answer is 615 g</h2>

Explanation:

The mass of a substance when given the density and volume can be found by using the formula

<h3>mass = Density × volume</h3>

From the question

volume of seawater = 600 mL

density = 1.025 g/mL

The mass is

mass = 600 × 1.025

We have the final answer as

<h3>615 g</h3>

Hope this helps you

The electron configuration filling patterns of some elements in group 6b(6) and group 1b(11) reflect the ______ of half-filled a
Fudgin [204]

The electron configuration filling patterns of some elements in group 6b(6) and group 1b(11) reflect the increasing stability of half-filled and completely filled sublevels.

<h2>What is electronic configuration?</h2>

The distribution of electrons in an element's atomic orbitals is described by the element's electron configuration. Atomic subshells that contain electrons are placed in a series, and the number of electrons that each one of them holds is indicated in superscript for all atomic electron configurations. For instance, sodium's electron configuration is 1s22s22p63s1.

Almost all of the elements write their electronic configurations in the same style. When the energies of two subshells differ, an electron from the lower energy subshell occasionally goes to the higher energy subshell.

This is due to two factors:

Symmetrical distribution: As is well known, stability is a result of symmetry. Because of the symmetrical distribution of electrons, orbitals where the sub-shell is exactly half-full or totally filled are more stable.

Energy exchange: The electrons in degenerate orbitals have a parallel spin and are prone to shifting positions. The energy released during this process is simply referred to as exchange energy. The greatest number of exchanges occurs when the orbitals are half- or fully-filled. Its stability is therefore at its highest.

Why do cells carry out cellular respiration
vitfil [10]
<span>Plants and animals carry out cellular respiration, but only plants conduct photosynthesis. Cellular respiration is the process in which a cell uses oxygen to convert glucose, a simple sugar, into the energy-carrying molecule, adenosine triphosphate (ATP).

hope this helps :)</span>
