Answer 1

<b>I don't know exactly what you want on some of these. I will answer some but not all of these to get you started. For those I don't answer, please repost and tell me what you don't understand about it/them.</b>

NaCl [Symbol] Na + Cl2
Type of reaction: synthesis
<b> No. Synthesis is the reverse; i.e., Na + Cl2 ==> 2NaCl. </b>


KOH + HNO3 [Symbol] HOH + KNO3
Type of reaction: double replacement
<b>OK</b>


Ca + S [Symbol] CaS
Type of reaction: synthesis
<b>OK</b>

BaBr2 + Cl2 [Symbol] BaCl2 + Br2
Type of reaction:
<b>single replacement</b>

Cs2 + H2O [Symbol] CsOH + H2
Type of reaction:
<b>I don't know what Cs2 is.</b>

Na2CO [Symbol] Na2O + CO2
Type of reaction:
<b>I think you meant Na2CO3. That would be decomposition</b>

Cu + I [Symbol] CuI
Type of reaction: synthesis
<b>Yes, if you wrote the equation right. Should be 2Cu + I2 ==> 2CuI</b>

HCl + Mg(OH)2 [Symbol] MgCl + H2O
Type of reaction:
<b> 2HCl + Mg(OH)2 ==> MgCl2 + 2H2O. Isn't this the same as the HNO3 + KOH? </b>

Fe + F2 [Symbol] FeF2
Type of reaction:
<b> This is the same type as Ca + S isn't it.</b>


Ni + NaCl [Symbol] NiCl + Na
Type of reaction: single replacement
<b>Yes, the type is correct BUT that reaction will not occur</b>
