Answer:
B one mole of carbon is lighter than one mole of magnesium
Answer:
Atoms consist of a nucleus made of protons and neutrons orbited by electrons.
Isotopes are atoms that have same number of protons but they differ in the number of neutrons and in atomic mass.
A piece of paper is thin, slighlty smooth, can be white and smells woody. 500 g of butter has a density of 0.911 g/ml and has a volume thus of 548.85 ml. Butter has a color yellow and smells fatty. A glass of milk has a white color, sour smell and taste and the milk occupies the volume of glass. Candle is waxy, can be long or short, can have colors of different varieties and is cylindrical.
Answer:The functional groups in an organic compound can frequently be deduced from its infrared absorption spectrum. A compound, C5H10O2, exhibits strong, broad absorption across the 2500-3200 cm^1 region and an intense absorption at 1715 cm'^-1. Relative absorption intensity: (s)=strong, (m)-medium, (w) weak. What functional class(cs) docs the compound belong to List only classes for which evidence is given here. Attach no significance to evidence not cited explicitly. Do not over-interpret exact absorption band positions. None of your inferences should depend on small differences like 10 to 20 cm^1. The functional class(es) of thla compound is(are) alkane (List only if no other functional class applies.) alkene terminal alkyne internal alkyne arene alcohol ether amine aldehyde or ketone carboxylic acid ester nitr
<u>Answer:</u>
<em>The number of moles of HCl actually present is 0.000988</em>
<u>Explanation:</u>
<em>The balanced chemical equation of the given reaction is </em>
Here one mole of HCl reacts with one mole of NaOH to form one mole of NaCl and one mole of water. Here the molarity of HCl is given as 0.026M.
<em>molarity of NaOH is 0.032M
</em>
molarity is the number of moles per unit volume of solution.
we have to calculate the number of moles in 36 mL of HCl.
<em>38 mL=36/1000=0.038L
</em>
<em>the number of moles in 38 mL of HCl is given by
</em>
<em>no of moles =
</em>
