The source of heat energy would be the electrical energy
By this i mean that the electric kettle converts the electrical energy from the outlet into heat energy
Answer:
58.32
Explanation:
The mass number is one mole and for Mg it is 24.306 for O it is 15.999 and for H it is 1.008. because O and H have 2, you multiply them by 2 and add all the numbers and it equals 58.32

Hello,
The question above requires us to classify certain properties which may either fall into physical or chemical properties of that matter.
Physical properties are properties which are of intrinsic value and has no influence on the chemical nature of the substance while chemical properties are those that influence the chemical nature of the substance.
Physical properties can be measured or calculated while chemical properties of a substance is very difficult to measure.
a). Silver has a shiny luster is an example of "physical property" because the shiny nature of silver has no chemical importance.
b). Silver metal has a density of 10.49 g/cm³ is also a "physical property" because density is a physical property of a material.
Density is ratio between mass and volume which are both physical properties since they can be measured.
c). Silver metal and Chlorine gas produce Silver chloride (AgCl) is a "chemical property" since it involves combining of two elements and they both lose their original chemical identity after the reaction.
d). Silver metal has a melting point of 1235°C is a "physical property"
e). Silver metal conducts electricity is a "chemical property" since conduction of electricity are done by the availability of mobile electrons in its electron cloud.
f) silver metal gives no reaction to acid is also an example of "chemical property"
Answer:
See explanation below
Explanation:
In this case, we are having a reaction between an anion and alkyl halide. The carbon 1 of the anion will act as nucleophile and will attack the electrophile, which is 5 carbon chain with the bromine in the third carbon.
Now, the nucleophyle is an alkyne of 3 carbon. According to the description, it should be:
CH₃ - C ≡ C⁻
And the alkyl halide is:
CH₃ - CH₂ CH(Br) - CH₂ - CH₃
And the final product after the reaction would be the following:
CH₃ - C ≡ C - CH - (CH₂CH₃)₂
However, in the attached picture you can see this better and the mechanism of reaction.
Hope this helps
