Answer: C) C6H12O6

Explanation: The molar mass is the mass of a given substance (chemical element or chemical compound (in grams.) divided by its amount of substance (in mole). To determine which of the given options is the molecular formula of glucose, we need to calculate the molar mass of each one of them, and compare them with the given value (180.18 grams per mole):

molar mass of the elements:

C=12

H=1

O=16

A) mCHO=12+1+16=29 g/mol

B) mC3H4O3=12*3+1*4+16*3=88g/mol

C) mC6H12O6=12*6+1*12+16*6=180g/mol

D) mC12H24O12=12*12+1*24+16*12=360g/mol

As we can see, the correct answer is option C.

Answer:

Remain the same.

Explanation:

The reaction of the temperature of the content of the container will remain the same because no heat energy is transfer from the container to the external environment due to insulating material of the container. Insulators are poor conductor of heat and electricity so the container is unable to absorb the heat energy produced during a chemical reaction and all energy of the product remain the same.

lesantik [10]

Answer:

Explanation:

The conclusions from Thomoson's claims would be invalid if his experiment could not be replicated.

<em>One of the attributes of a valid experiment in science is replication. That is, an experiment must be repeatable with similar outcomes under similar conditions as the original experiment when independently performed by another scientist. Once an experiment cannot be replicated, the outcomes of such an experiment become invalid in science.</em>

Hence, <u>Thomoson's conclusion would be invalid if his experiment could not be replicated. </u>
