The base gram of the compound is 16.042
To find the new amount of grams, you need to multiply the amount of moles by the the base grams
16.042*.25=4.01
So one fourth of the compound is 4.01 grams of Carbon tetrahydride.

3. 5. and i think thats it
Answer:
1640 kJ are involved in the reaction
Explanation:
In the reaction:
B₂H₆(g) + 6Cl₂(g) → 2 BCl₃(g) + 6HCl(g)
<em>1 mol of B₂H₆(g) with 6 moles of Cl₂(g) produce 1396 kJ of energy.</em>
<em />
Now if 32.5g of B₂H₆(g) react with excess Cl₂(g), moles involved in reaction are:

If 1 mol produce 1396kJ of energy, 1.175 moles produce:

Thus, <em>1640 kJ are involved in the reaction</em>
The Mohs scale is for natural minerals<span>. For manufactured products other measures of hardness are better. ... There are ten </span>minerals<span> in Mohs scale, talc, gypsum, calcite, fluorite, apatite, orthoclase, quartz, topaz, corundum, and for last and</span>hardest<span>, diamond.
