Rosa is breathing normally and eats a peanut butter sandwich for lunch. Peanut butter contains a lot of protein, and bread is mo

stly starch. Rosa plans to go for a run later this afternoon.
What does she need from the food she ate and the air she breathes so that she can go on her run? How do Rosa’s body systems work together to get the molecules she needs into her cells? How do her cells use these molecules to make energy for her body to run?

sweet-ann [11.9K]
An aldehyde is an organic compound containing a terminal carbonyl group (C = O). This functional group, consisting of a carbon atom bound to a hydrogen atom and an oxygen atom via double bond (the general formula: CHO) is called the aldehyde group. In a reaction of the addition of alcohol to the carbonyl group, it forms hemiacetals. 
On the picture attached it is shown the reaction of alcohol addition to the carbonyl group with the major organic product <span>formed in the reaction.</span>

How many moles are in 715.11 grams of Ca(C2H302)2?
nikdorinn [45]

Answer:

4.52 mol

Explanation:

We do grams/Molar Mass to find the number of moles. The grams are given but the molar mass, you have to add all masses of the elements up by refering to a periodic table, and you should get that the compound has a mass of 158.168. Do 715.11 dived by that and you get the answer above.

Thallium consists of 29.5%TI-203 and 70.5%TI-205. What is the relative atomic mass of thallium
Galina-37 [17]
To determine the relative atomic mass of thallium, we multiply the molar mass of the isotopes to their corresponding relative abundance. The molecular percentages should sum up to 1. In this case, we multiply 203 by 0.295 and 205 by 0.705 and add the answers of the two. The final atomic mass is 204.41 g/mol.

Does the excess reactant get used up completely in a reaction??
Alex787 [66]

Answer:

In a chemical reaction, reactants that are not used up when the reaction is finished are called excess reagents. The reagent that is completely used up or reacted is called the limiting reagent, because its quantity limits the amount of products formed.
