Answer:
Azurite and Magnesite react with hydrochloric acid.
Explanation:
These 2 rocks contain the carbonate mineral calcite dolomite. Carbonate minerals are unstable in contact with hydrochloric acid. When acid begins to effervesce (fizz) on a specimen, a reaction takes place and bubbles of carbon dioxide evolve, thus indicating the presence of minerals like calcite dolomite.
Hope my answer is correct and helpful :)
Answer:
- <u>The hours are the independent variable.</u>
- <u>The wages/wk earned are ( $11/hr )x( hrs worked )
. This is the dependent variable ( depends on hours worked )
.</u>
- <u>The domain is 0 to 30
</u>
- <u>The range is 0 to 330
</u>
Explanation:
<em>The hours are the independent variable and should be plotted on the x-axis
.</em>
<em>The wages/wk earned are ( $11/hr )x( hrs worked )
. This is the dependent variable ( depends on hours worked ) and should be plotted on the y-axis
</em>
<em>---------------
</em>
<em>Let +W+ = wages/wk earned
</em>
<em></em>
<em>Let +h+ = hours/wk worked
</em>
<em>The equation is:
</em>
<em>+W+=+11h+
</em>
<em>The domain is 0 to 30
</em>
<em>( no hrs worked to 30 hrs worked )
</em>
<em>The range is 0 to 330
</em>
<em>( no wages eared to +11%2A30+=+330+ earned )</em>
The shoulder (pectoral) and pelvic girdles are both structures for limb articulation. The shoulder girdles are to the upper limbs as the pelvic girdle is to the lower limbs. Shoulder girdles connect the upper arms with the axial skeleton and consist of the clavicle and scapula.
The pelvic girdles consist of the hip bones, the sacrum and the coccyx and are located between the abdomen and the thighs.
