First, write out a complete balanced reaction for the combustion of ethane, ethane + O2 -> CO2 + H20. Then, divide the grams of ethane by its Molar Mass and multiply by 32, the molar mass of O2.
The answer is B. The s orbital holds a maximum of 2 electrons, where the p orbital holds a maximum of 6 electrons.
Answer:
A
Explanation:
Two specialized cells called 'guard cells' make up each stoma (stoma is singular for stomata). Plants have many stomata up to 400 per mm2 on their leaf surfaces and they are usually on the lower surface to minimize water loss.
*** Remember ***<u /> Dehydration synthesis is when two molecules are joined together, by removing a water molecule. Also a key thing to remember is that <em>dehydration</em><u /> can be remembered as "losing water".
During dehydration synthesis, a <u> water </u><u /> molecule is produced.
I hope this helps! :D
<span>b) a positive metal ion and a negative nonmetal ion.
</span>Because generally ions of non-metal elements (such as the halogens) are negatively charged while ions of metal elements (such as the alkali earth metals) are positively charged. The differences in their changes causes strong electrostatic attraction (an ionic bond).
