Answer:

Y= 98, 0% , Z = 94,7 %

Explanation:

We use simple 3 rules to find the percentage of purity, using mass data:

Sample Y =

85g----100%

83,30g----X = (83,30gx 100%)/ 85g= 98, 0%

Sample Z =

95g----100%

90g----X = (90gx 100%)/ 95g= 94, 7%

Answer:

98.0, 94.7

Explanation:

From the image, the percentage remaining (PR) can be mathematically computed as:

PR = final mass/initial mass x 100%

PR for sample Y = final mass of Y/initial mass Y x 100%

= 83.30/85.00 x 100% = 98.0% (to the nearest tenth of a percent)

PR for sample Z = final mass of Z/initial mass of Z x 100%

= 90.00/95.00 x 100% = 94.7% (to the nearest tenth of a percent)

<em>Hence, the percentage remaining of sample Y is 98.0 percent and that of sample Z is 94.7% </em>

Why are the layers in the rock important?​
Viktor [21]

Answer:

Explanation:

 Why are layers of rocks related to each other?

Layering, or bedding, is the most obvious feature of sedimentary rocks. ... This Law of Superposition is fundamental to the interpretation of Earth history, because at any one location it indicates the relative ages of rock layers and the fossils in them. Layered rocks form when particles settle from water or air.

What do ferromagnesian (mafic) minerals have in common? List three examples of mafic minerals?
saveliy_v [14]

Ferromagnesian minerals are minerals that have iron or magnesium in their structure. The greater specific gravity is between 3.2 and 3.6. Some examples are pyroxene, biotite, garnet, and olvine.

Most mafic minerals are dark in color, and common rock-forming mafic minerals include olivine, pyroxene, amphibole, and biotite. Common mafic rocks include basalt, diabase and gabbro. Mafic rocks often also contain calcium-rich varieties of plagioclase feldspar.
