Answer:
Part 1: W = 116 Y = 163
Part 2: Since 232 is the mailing point of 2 kg then you would divide 232 by 2 to get the melting point for 1 kg, the same with Y.
Acids tend to have a pH of below 7 (which is neutral).
The only option that makes the pH statement above true is A, 6.
So the answer is with no doubt, A. 6
Answer:
Heat or electricity in the atmasphere
Explanation:
D. A broken piece of quartzite will break through, not around, quartz sand grains.
Quartzite and quartz sandstone have the <em>same chemical formula</em> (SiO_2)
Quartzite is a <em>metamorphic rock</em>. Heat and pressure have compressed the sand into a strong network of interlocking quartz grains.
Quartzite is so tough that it breaks through the sand grains rather than around them as in sandstone.
