Answer:
The 150 g Al will reach a higher temperature.
Explanation:
- The amount of heat added to a substance (Q) can be calculated from the relation:
<em>Q = m.c.ΔT.</em>
where, Q is the amount of heat added,
m is the mass of the substance,
c is the specific heat of the substance,
ΔT is the temperature difference (final T - initial T).
Since, Q and c is constant, ΔT will depend only on the mass of the substance (m).
∵ ΔT is inversely proportional to the mass of the substance.
<em>∴ The piece with the lowest mass (150.0 g) will reach a higher temperature than that of a higher mass (250.0 g).</em>
<em>So, the right choice is: The 150 g Al will reach a higher temperature.</em>
The $ -(Br) at that instant is calculated as follows
BrO3 + 5Br ---> 3Br2 + 3 H2o
by use of reacting ratio BrO3 to Br2 which is 1:3
therefore $ of Br = 3 x (1.5 x10^-2)= 4.5 x10^-2

Answer:
A. Carboxyl group
Explanation:
The carboxyl group is an organic functional group in chemistry that consists of a carbon atom double-bonded to an oxygen atom and singly linked to a hydroxyl group. Another way to think about it is as a carbonyl group (C=O) with an attached hydroxyl group (O-H).
The answer is D. This is because liquids take up the shape of the container they are in, so it is never definite. Where as solids stay the same shape.
