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>

Nataliya [291]

Answer:

sun/ visible light

moon/ invisible light

Explanation:

The Sun is the dominant source for visible-light waves our eyes receive. The outer-most layer of the Sun's atmosphere, the corona, can be seen in visible light. But it is so faint it cannot not be seen except during a total solar eclipse because the bright photosphere overwhelms it.The moon shines because its surface reflects light from the sun. And despite the fact that it sometimes seems to shine very brightly, the moon reflects only between 3 and 12 percent of the sunlight that hits it.
