Test Your Hypothesis by Doing an Experiment
Your experiment tests whether your prediction is accurate and thus your hypothesis is supported or not. It is important for your experiment to be a fair test.
Answer:
79'420J
Explanation:
We know mass 250g and
∆T=98°C -22°C
=76°C
The specific heat capacity for water is 4,18Zj/g°C
THEREFORE
∆H=250g•14,8j/g°C •76°C
=79'420J
<em>if u mix them ammonia will react with H2o2 to give N2 </em>
<em>since N2 is highly stable a lot of energy will be released in the reaction. </em>
<em>Hence the reaction will be explosive </em>
Answer:
a. BaCl2 is ionic compound.
b. CH4 is covalent compound.
b. MnO2 is ionic compound.
e. H2S is covalent compound.
c. H3AsO4 is ionic compound.
f. CH3OH is covalent compound.
Explanation:
BaCl2, MnO2 and H3AsO4 are ionic compounds due to the presence of ionic bond between the atoms while on the other hand, CH4, H2S and CH3OH are covalent compounds due to the presence of covalent bond between their atoms. In covalent bonds, sharing of electrons occur whereas in ionic bonds, complete transfer of electrons occur from one atom to another atom.
