A mixture contains 20% iron ions by mass. What mass of iron chloride (FeCl) would
omeli [17]

Mass of iron chloride (FeCl₂) : 22.68 g

<h3>Further explanation</h3>

Proust stated the Comparative Law that compounds are formed from elements with the same Mass Comparison so that the compound has a fixed composition of elements

In the same compound, although from different sources and formed by different processes, it will still have the same composition/comparison

With this law, we can calculate how many grams an element is needed to make a compound with a certain mass, as desired

<h3 />

\tt mass~Fe=\dfrac{Ar~Fe}{MW~FeCl_2}\times mass~FeCl_2

The iron ions in 50 g mixture :

\tt 20\%\times 50~g=10~g

\tt 10=\dfrac{56}{127}\times mass~FeCl_2\\\\mass~FeCl_2=22.68~g

Hi:)) how to do 5? I’m not sure if it’s hydrogen carbonate or carbonate
zysi [14]

Answer:

copper(ll) carbonate

Explanation:

Since the product is a salt which is copper(II) carbonate, water and carbon dioxide, this reaction is an acid + metal carbonate reaction.

Looking at the salt, Cu²⁺ has to be part of the reactants.

Hence, the missing compound there has to be copper(ll) carbonate, CuCO₃.

The balanced chemical equation would be:

CuCO₃ + 2HNO₃➙ Cu(NO₃)₂ +H₂O +CO₂

P.s. You left out CO₂ as a product in Q2 ;)

Just a recap of the main reactions you would've learnt:

1) Acid + base/ alkali ➙ salt + water

2) Acid + metal ➙ salt + hydrogen gas

3) Acid + metal carbonate ➙ salt + H₂O + CO₂

Which statement is true if the hrxn of a reaction is positive
Sonja [21]

Answer : The reaction is endothermic in nature.

Explanation : A system of reactants which absorbs heat from the surroundings in an endothermic reaction has a positive ΔH reaction value, as the enthalpy of the products is higher than the enthalpy of the reactants of the system.

As the enthalpies of these reactions are greater than zero, they are called as endothermic reactions. Which absorbs the heat during the chemical reactions.
