Answer:An endothermic reaction
Explanation: In an endothermic reaction, it takes more energy to break the bonds of the reactants than is released when the bonds in the products are formed. In an endothermic reaction, the temperature goes down.
Answer:
The independent variable is the type of material
The dependent variable is the thermal energy transferred by that material
Explanation:
The type of material is independent of the heat flowing through it. While the thermal energy transferred is surely dependent on the material through which it transfers.
S²⁻ cannot be reduced further.
<u>Explanation:</u>
S²⁻ cannot be reduced further
In the periodic table, Sulphur has the atomic number of 16.
So, the arrangement of electrons in the orbits would be 2, 8, 6
The outermost orbit has 6 electrons.
It can gain two more electrons to complete its outermost orbit and the valency of the sulphur then becomes 2-
Therefore, in S²⁻ the valence electrons are complete in the outermost orbit and cannot gain more electrons. Therefore, it cannot get reduced further.
Answer:
The median is also the number that is halfway into the set. To find the median, the data should be arranged in order from least to greatest. If there is an even number of items in the data set, then the median is found by taking the mean (average) of the two middlemost numbers.

Answer ( assuming that your brother is doing 4,000 grams and not 4 grams ) :
around 8 pound's
Explanation:
1 gram = around 0.002 gram's
4,000 x 0.002 = 8
8 pound's :-)
