Compare an electrically neutral atom of hydrogen and an isotope of hydrogen.

1 answer:

7 0

In comparison, a neutral hydrogen and an isotope of hydrogen have same chemical properties because o having the same number of protons and electrons, However, they have different number of neutrons which gives them their mass number. The difference in mass number gives the two isotope their mass related properties. For instance, a hydrogen isotope with an extra neutron will be much heavier than the neutral hydrogen.

Give the expression for the solubility product constant for baf2.

svetoff [14.1K]

Solubility product constant (Ksp) is applied to the saturated ionic solutions which are in equilibrium with its solid form. The solid is partially dissociated into its ions.

For the BaF, the dissociation as follows;
BaF₂(s) ⇄ Ba²⁺(aq) + 2F⁻(aq)

Hence,
Ksp = [Ba²⁺(aq)] [F⁻(aq)]²

2Fe + 3Cl2 → 2FeCl3 which of the following options gives the correct reactant ratio?

Mademuasel [1]

Answer: The reactant ratio in the given chemical equation will be: $Fe:Cl_2=2:3$

Explanation:

Mole ratio is defined as the ratio of the amount of moles of two substances that are participating in a chemical reaction.

In the given chemical equation:

$2Fe+3Cl_2\rightarrow 2FeCl_3$

The reactants are Fe and $Cl_2$ and the product is $FeCl_3$

The mole ratio is basically the stoichiometric ratio of the chemical compounds taking part in a chemical reaction.

The mole ratio of reactants is stoichiometric ratio of Fe and $Cl_2$ , which is:

$Fe:Cl_2=2:3$

Hence, the reactant ratio in the given chemical equation will be: $Fe:Cl_2=2:3$

A student is performing an experiment to study thermodynamics. The student mixes citric acid and sodium bicarbonate in a calorim

seraphim [82]

Explanation :

In thermodynamics, a system is region or part of space which is being studied and observed while the surrounding is the region or space around the system which interacts with the system.

Here in the experiment ,system which is observed is reaction or changes when citric acid and sodium bicarbonate are mixed together. And the mixing is carried out in the calorimeter which serves as a surrounding around the system.

The reason behind the using the calorimeter is measure the energy change occurring during the reaction.
