Answer:

Saturn. Saturn is the sixth planet from the Sun and the second-largest in the Solar System, after Jupiter. It is a gas giant with an average radius of about nine times that of Earth. It only has one-eighth the average density of Earth; however, with its larger volume, Saturn is over 95 times more massive.

What makes gabbro a rock and not a mineral

lozanna [386]

Gabbro is usually made up of such as pyroxene, plagioclase, amphibole and olivine which makes it an intrusive igneous rock. It is not considered as a mineral since it is composed of an aggregate of minerals or non-minerals and does not have one specific chemical composition.

. Explain the differences between a sponge and a sourdough starter. How are each of these items used

d1i1m1o1n [39]

Answer:

Less time is required when using the sponge method than with the sourdough method, and although the sponge method provides hints of the depth of flavor and texture that result from the sourdough method, these characteristics are not as pronounced as they are when using the sourdough method.

The atomic masses of the two stable isotopes of copper 63Cu29 (69.17 percent) and 65Cu29 (30.83 percent)â are 62.929599 and 64.9

FromTheMoon [43]

Answer:

Average atomic mass of copper is 63.545642 amu

Explanation:

100 atoms of copper contains 69.17 number of $Cu_{29}^{63}$ atoms and 30.83 number of $Cu_{29}^{65}$ atoms.

Therefore average atomic mass of copper is given by-

$\frac{(69.17\times atomic mass of Cu_{29}^{63})+(30.83\times atomic mass of Cu_{29}^{65})}{100}$

= $\frac{(69.17\times 62.929599 amu)+(30.83\times 64.927793 amu)}{100}$

=63.545642 amu

At a certain temperature, a saturated solution of lead chromate (PbCrO4) has 4.33 x 10-6 g dissolved in 100 mL of water, a conce

sweet [91]

This question is providing us with the concentration of a lead (II) chromate solution at its saturation point and asks for its solubility product. Thus, after the corresponding calculation, the result turns out to be 1.80x10⁻¹⁴.

<h3>Solubility products</h3>

In chemistry, solubility tells us how much solid is dissolved in a solvent before exhibiting a precipitate (undissolved solid). This can be calculated with the concept of solubility product based on the equilibrium the solid creates with its ions, which for this case looks like;

$PbCrO_4(s)\rightleftharpoons Pb^{2+}(aq)+CrO_4^{2-}(aq)$

Whose equilibrium expression is:

$Ksp=[Pb^{2+}][CrO_4^{2-}]$

Hence, since the solid and the ions are all in 1:1:1 mole ratios, we set the concentration of the ions equal to that of solid at equilibrium (saturation), in order to obtain the Ksp:

$Ksp=(1.34x10^{-7})(1.34x10^{-7})\\\\Ksp=1.80x10^{-14}$
