Answer:Its c
Explanation:
Let us use a double displacement reaction of Lead (II) Nitrate and Potassium Chromate to produce Lead (II) Chromate and Potassium Nitrate to practice balancing an equation.
We begin with the base equation provided in the question.Pb(NO3)2(aq)+K2CrO4(aq)→PbCrO4(s)+KNO3(aq)
Looking at the the atom inventory ReactantsPb=1NO3=2
K=2CrO4=1
Products
Pb=1
NO3=1
K=1
CrO4=1
We can see that the
Kand NO3
are imbalanced.
If we add a coefficient of 2 in front of the
KNO3
this will balance the equation.
Pb(NO3)2(aq)+K2CrO4(aq)→PbCrO4(s)+2KNO3(aq)
Answer:
yes they are
Explanation:
if you are heating up glass i believe not, unless you want to break the glass. Making glass go from high to low or low to high tempuatures quickly will cause it to break. How ever metal will be stronger as long as you dont bend it.
