Answer:
H2SO4+CU(OH)2 = CUSO4+2H2O
The general neutralization reaction between an acid and a base takes the form: acid + base → salt + water.
If you have some acid HA neutralizing some base BOH, the salt would be an ionic compound composed of the conjugate acid of BOH (i.e., B⁺) and the conjugate base of HA (i.e., A⁻).
Applied here, H2SO4 and Cu(OH)2 would react to form a salt CuSO4 (the Cu²⁺ ions coming from the copper(II) hydroxide and the SO4²⁻ ions coming from the sulfuric acid) and H2O.
Thus, the products of this neutralization reaction would be copper(II) sulfate (CuSO₄) and water (H₂O).
The balanced equation for this reaction would accordingly be:
H₂SO₄ + Cu(OH)₂ → CuSO₄ + 2H₂O.

Answer:
Calcium hydroxide + Carbon dioxide → Calcium carbonate + Water
(b) Zinc + Silver nitrate → Zinc nitrate + Silver
(c) Aluminium + Copper chloride → Aluminium chloride + Copper
(d) Barium chloride + Potassium sulphate → Barium sulphate + Potassium chlorid

Identify the daughter isotope in this nuclear reaction: Superscript 222 subscript 88 upper R a right arrow superscript 218 subscript 86 R n plus superscript 4 subscript 2 upper H e. Which is the daughter isotope? Superscript 218 subscript 86 R n. Superscript 4 subscript 2 upper H e. Superscript 222 subscript 88 upper R a.
The daughter isotope which is present in the given radioactive decay is ²¹⁸₈₆R.
What is daughter isotope?A daughter isotope is the isotope that remains following the radioactive decay of an original isotope.
In the question parent nuclei is given that ²²²₈₈R, and given chemical equation is:
²²²₈₈R → ²¹⁸₈₆R + ⁴₂He
In the above equation ²¹⁸₈₆R is the daughter nuclei and ⁴₂He is the emitted particle or rays.
Hence ²¹⁸₈₆R is the daughter isotope.

.What is the KE of a baseball that has a mass of 100 kg and is traveling at 5 m/s?
Answer:
1250joules
Explanation:
The kinetic energy is energy in motion and it's formula is
KE =1/2MV^2
M represent mass which is 100Kg.
V represent velocity which is 5m/s
Therefore, KE = 1/2×100×5× 5
= 50 × 25
KE= 1250joules

Answer:
Explanation:
1. New substances such as carbondioxide and water is formed.
2. There is evolution of gas bubbles. Gases are released.
3. There is either the absorption of energy or release of energy in form of light and energy.
4. The reaction is irreversible i.e it cannot be reversed, it is permanent once the reaction take place.
5. There is a change in both odor and smell.
A chemical change is a change where new substances are formed due to changes in the properties.

What is used up in and stops a chemical reaction?
Answer:What is used up in and stops a chemical reaction? (a) percent yield (b) limiting reactant (c) theoretical yield (d) excess reactant
The correct option is (b)
Explanation:
A chemical reaction is a chemical combination,rearrangement or disintegration of chemical substance(s) (called reactants) to form new chemical substance(s) (called products).
A limiting reactant is the reactant that is totally used up during the course of a reaction. When this reactant is used up, it limits the amount of products formed and eventually stops the chemical reaction.
Explanation:
The limiting reagent is the reactant that is used up completely. This stops the reaction and no further products are made. ... This method is most useful when there are only two reactants. The limiting reagent can also be derived by comparing the amount of products that can be formed from each reactant.

What is the number of copper atom in one naira coin which weight is 7.3g a sum of the material is 86%
Answer:
5.9x10²² atoms of Cu are in one naira coin
Explanation:
To solve this question we need to find the mass of Copper. Then, using its molar mass (Cu = 63.546g/mol) we must find the moles of Cu and its atoms using Avogadro's number:
Mass Cu:
7.3g * 86% = 6.278g is the mass of Cu.
Moles Cu:
6.278g * (1mol / 63.546g) = 0.099moles Cu
Atoms Cu:
0.099moles Cu * (6.022x10²³atoms / 1mol) =
