Mass = number of moles x molar mass
carbon dioxide: CO2
mass = 0.25 x (12 + 16 + 16)
mass = 0.25 x 44
mass = 11g
Answer:
A !!
Explanation:
because the equator is basically all the weather , so it cant be d , c , or b because in the artic is not hot and the desert cant be cold . so the answer is A
1) Chemical equation.
2) Types of reaction.
In the reaction above, we can see that two different compounds get together to form a new compound. <em>This is called a synthesis or a combination.</em>
Decomposition: A compound is broken down into simpler compounds.
Combustion: A compound containing Carbon and Hydrogen combines with oxygen.
Double replacement: Positive and negative ions in two compounds switch places.
Answer:
See explanation
Explanation:
In this case, we have to know where we have to do. We have to remove a "Br" and put a methyl group and for this, we need to use a Gilman reaction. (See figure 1). We have to start with <u>bromomethane</u> that reacts with Li to form <u>methyllithium</u>. Then we have to do the reaction with Copper to obtain the Gilman reagent <u>dimethylcopper</u>. Finally, we have to do the reaction with the halide <u>1-bromocyclohexene</u> to form <u>1-methylcyclohexene</u>.
See figure 1
I hope it helps!
