Ugo [173]3 years ago
5 0

Answer :

Double replacement reaction : It is a type of reaction in which a positive cation and a negative anion of the reactants react to give a new compound as  a product.

AB+CD\rightarrow AD+CB

In this, A and C are the cations and B and D are the anions.

When one mole of potassium hydroxide react with the one mole of zinc chloride to give one mole of zinc hydroxide and 2 moles of potassium chloride.

The balanced chemical reaction is,

KOH+ZnCl_2\rightarrow Zn(OH)_2+2KCl

1. Is a hurricane or a tornado deadlier on average?
Vilka [71]

Stoms or tornadoes cause about ten times more damage a year, on average, as hurricanes. Storms often cause more complete destruction than hurricanes because of their large size, long-term duration, and their varied potential for damage to property.

Storms can be very severe storms, hurricanes often last a long time, cover most of the earth and cause great damage. The wind from the strongest calves is stronger than the one from the strongest storms.

Which of the following is the correct equation for the reaction below?
fenix001 [56]

Answer:

Option C.

2 Mg (s) + O₂(g) →  2MgO (s)

Explanation:

Two moles of magnesium solid react with one mol of oxygen gas to

form two moles of magnesium-oxide solid

2 Mg (s) + O₂(g) →  2MgO (s)

That's the reaction for the magnessium oxide's formation.

Be careful cause we do not say molecules, they are moles.

The stoichiometry indicates the number of moles that react and the moles which are produced.

It is a redox reaction, because the magnessium is oxidized and the oxygen is reduced. Both elements, changed the oxidation states.

23491pa undergoes beta decay. what is the mass number of the resulting element?
qaws [65]
Answer is: mass number is 234.
Beta decay is radioactive decay<span> in which a </span>beta ray<span> and a </span>neutrino<span> are emitted from an </span><span>atomic nucleus.
</span>There are two types of beta decay: beta minus<span> and </span>beta plus. <span> In beta minus </span><span>decay, neutron is converted to a proton and an </span>electron<span> and an </span>electron antineutrino and in beta plus <span>decay, a proton is converted to a neutron and </span>positron<span> and an </span>electron neutrino, so mass number does not change.
