Answer:
2NaCN + CaCO3 --> Na2CO3 + Ca(CN)2
Explanation:
Knowing the names gets us: NaCN + CaCO3 --> Na2CO3 + Ca(CN)2
Balance: there are two sodiums and cyanides on the product side so add a 2 to the reactant side.
Liquid!
Liquid matter is made of more loosely packed particles.
Answer:
c.The atoms in the solid would be vibrating in position.
Explanation:
The properties of solid, liquid and gas which makes them different ares the intermolecular interactions between particles and the thermal energy.
Solids molecules are fixed in their position and may show vibrations.
Liquid molecules can move slowly as they have inter-molecular forces in between solid and gas,
Gas molecules can move vigorously here and there due very weak inter-molecular interactions and high thermal energy.
Thus the answer would be the atoms in the solid would be vibrating in position.
Answer:
The voltage delivered by a primary battery is unrelated to its size.
The negative ion in aqueous sodium hydroxide, NaOH(aq) is hydroxide ion, OH-.
<h3>What is a neutralization reaction?</h3>
A neutralization reaction is a reaction between an acid and a base to form salt and water only.
The reaction between vinegar and NaOH is a neutralization reaction which produces a salt and water only.
NaOH is composed of a positive sodium ion, Na+ and a negative hydroxide ion, OH-
Therefore, the negative ion in the NaOH(aq) used in this titration is hydroxide ion, OH-.
