Explanation:
The statement in the question above gives the statement of the law of conservation of matter. The law of conservation of matter states that matter can neither be created nor destroyed but can be converted from one form to another.
This particular law is talking about the indestructible nature of matter. Whatever form of matter we have presently was as a result of the fact that it was converted to from one initial form. It is this fundamental law that guides the operation of a wide number of scientific operations. Things like reaction between substances to form entirely or partially new substances are guided by these fundamental laws of nature
Answer:
ΔT = 76.5 °C
Explanation:
Given data:
Amount of water = 100.0 g
Energy needed = 32000 J
Change in temperature = ?
Solution,
Formula:
Q = m.c. ΔT
Q = amount of heat absorbed or released
m = mass of given substance
c = specific heat capacity of substance
ΔT = change in temperature
Now we will put the values in formula.
Q = m.c. ΔT
ΔT = Q / m.c
ΔT = 32000 j/ 100.0 g × 4.184 j/g. °C
ΔT = 32000 j / 418.4 j /°C
ΔT = 76.5 °C

What is a compound?
- A compound is a substance that is made up of atoms from different elements.
- The formula of a compound shows the elements making up the compound.
- Additionally, the formula of compound shows the number atoms of each element making up the compound.
In this case;
We are given the Formula KBr
- This is the formula of the compound potassium bromide.
- From the formula, we can tell that the compound is made up of potassium and bromine atoms.
- The formula also shows the number of atoms of each element, that is, 1 potassium atom and 1 bromide atom.
