Answer:
true im pretttyyy sure
Explanation:
bcuz the stronger the intermolecular forces the higher the boiling point :3
Answer:
A. It is exothermic
Explanation:
Combustion is a chemical reaction in which a substance combines with oxygen present in air to produce carbon (iv) oxide and water as well release heat and light energy.Combustion is an exothermic process.
An exothermic reaction releases energy in the form of heat to the surroundings. The energy required to break bonds in the reactants is less than the energy required to form new bonds in the products in an exothermic reaction.
From the given options;
A. It is exothermic is determinable since the reaction is a combustion reaction
B. The bond making energy is more than 600 kJ is not certain because the mass of the wood being burnt is not given. Also, wood is not composed of a specific element that would be taking part in the reaction, rather it is composed of various substances.
C. It is endothermic. is wrong because combustion of wood is exothermic.
D. The bond breaking energy is more than 600 kJ is not certain because the mass of the wood being burnt is not given. Also, wood is not composed of a specific element that would be taking part in the reaction, rather is composed of many substances.
Answer:
Hey weirdo what's up?
So you got a question huh?
Lemme answer
As said the correct reading is 3.0grams
And the option A has 3.01 and 2.99 which are very mush precise and accurate to 3.0 gram don't you think?
So the answer is
Option ii the result of students A is both precise and accurate
Loye ya
Peace out
Answer:
Ag(I)C2H3O2 ....................
Silver only has a single valence value (+1) so you really don't need to put the (I) in the chemical formula.
