I think the answer is it turnes into a gas. Hope it helps! :) Asnwer is density.
Answer:
Explanation:
A1. Chemical indicator, any substance that gives a visible sign, usually by a colour change, of the presence or absence of a threshold concentration of a chemical species, such as an acid or an alkali in a solution. An example is the substance called methyl yellow, which imparts a yellow colour to an alkaline solution.
A2. The reaction of an acid with a base is called a neutralization reaction. The products of this reaction are a salt and water. ... For example, the reaction of hydrochloric acid, HCl, with sodium hydroxide, NaOH, solutions produces a solution of sodium chloride, NaCl, and some additional water molecules
A3. Methyl orange has the property to color alkaline and neutral water yellow. If the water becomes acidic, it turns red immediately.
Answer:
20.11 g.
Explanation:
What is given?
c (specific heat of iron) = 0.450 J/g °C.
Q (heat energy) = 179.85 J.
ΔT (change of temperature) = |31.42 °C - 51.29 °C| = 19.87 °C.
What do we need? Mass of iron (m)
Step-by-step solution:
Let's see the formula of specific heat:
Where c is specific heat, Q is heat energy, m is mass and ΔT is the change of temperature.
We just have to solve for 'm' to find the mass of iron and replace the given data that we have, like this:
The mass of the iron would be 20.11 g.
I think the answer is solvent but i'm not very sure.
