Answer:
H2SO4 (aq) + 2LiOH (aq) --> Li2SO4 (aq) + 2H20 (l)
Answer:
Solution 1 has a higher pH at the equivalence point because CH3CO2H has the stronger conjugate base.
Explanation:
Since according to the chemical reaction shown below, if the conjugated base is stroboscopic, the product of the reaction would be an OH- so that its pH is higher:
CH3COO- + H2O = CH3COOH+ OH-
Answer:
- <em><u>Option A. </u></em><u><em>2KClO₃ → 2KCl + 3O₂</em></u>
Explanation:
There are five basic general types of chemical reactions:
- Synthesis or combination reaction
- Single replacement reactions
- Double replacement reactions
The given reactions are:
- <u>2KClO₃ → 2KCl + 3O₂</u>
Which is, indeed, a decomposition reaction because the reactant, KClO₃, is a single substance that undergoes a reaction in which it yields two new substances, known as products: KCl and O₂.
- <u>4Na + O₂ → 2Na₂O</u> is a synthesis or combination reaction because two reactants, Na and O₂, combine for the formation of one single new product, Na₂O.
- <u>ZnS + 3 O₂ → 2ZnO + 2SO₂ </u>is a single replacement reaction because oxygen is replacing Zn and S in ZnS to form ZnO and plus SO₂.
- <u>2NaBr + CaF₂ → 2NaF + CaBr₂ </u>is a double replacement reaction because two ions (Br⁻ from NaBr and F⁻ from CaF₂) are exchanging places with other two ions (Na⁺ from NaBr and Ca²⁺ from CaF₂) two form two new ionic compounds (NaF and CaBr₂).
Answer:
In my perspective I think its D because Electrical energy is converted to light and heat
Answer:
This is because their atoms have the same number of electrons in the highest occupied energy level. Li lithium and K potassium both belong to first group (alkali metals) and thus have similar chemical properties.
