Frosted glass and wax paper are ___

Heating glucose, a monosaccharide sugar, in the presence of excess oxygen produces carbon dioxide gas and water vapor. Balance t

lozanna [386]

Answer:

The balance reaction is C6H12O6+6O2=6CO2+6H2O

Explanation:

The reaction mentioned above is the reaction of cellular respiration.In this reaction glucose molecule reacts with oxygen to generate carbon dioxide,water and energy in form of ATP.

In the left side there are 6 carbon atoms,12 hydrogen atoms and 18 oxygen atoms and the same number of carbon,hydrogen and oxygen is present in the right side of the reaction mentioned above.Thus the reaction can be balanced.

Andrew [12]

Answer:

Option C= Cobalt is not used in medicine

This statement is incorrect.

Explanation:

Pyrite is an ore of gold and is used in jewelry making (correct statement)

Pyrite:

1. pyrite is yellow brass mineral.

2. its chemical composition is FeS2.

3. it is also called ore of gold

4. it is used in jewelry.

Talc:

Talc is used in paper making, plastics, and paint (correct statement)

1. it is phyllosilicate mineral in the form of sheets.

2. its chemical formula is Mg3Si4O10 (OH)2.

3. it is very important constituent of roofing material.

4. it is used in many industries like paper making, paints, electrical cables, food etc.

Quartz:

Quartz is used to make glass (correct statement)

1. its chemical formula is SiO2.

2. its large amount is used in manufacturing of ceramic and glass.

3. The second most abundant mineral found in the earth crust is also quartz.

Cobalt:

Cobalt is not used in medicine (incorrect statement)

1. Cobalt is widely used in medical field.

2. it is used in the detection of metastasis and tumor.

3. it is used in the replacement of knee and hip as a prosthetic alloys.

Minerals are very important in our daily life. They are widely used in construction material for example in the construction of buildings and roads and also in medical field.

Examples:

1. Copper is used in the electronic and electrical field.

2. Zinc is used in rust resistant metals, skin care creams. rubber paints etc.

Amphetamine was developed initially as a substitute for a closely-related chemical derived from the Chinese herb ma huang. That chemical is Ephedrine.

<h3>What is Ephedrine?</h3>

Ephedrine is a stimulant medication that can be considered an amine chemical compound and substituted amphetamine.

Ephedrine is used in sports to stimulate the central nervous system (C_NS) and as energy supplier.

Ep_hedrine use is prohibited and chronic usage of this substance may have problems the health.

For the decomposition of calcium carbonate, consider the following thermodynamic data (Due to variations in thermodynamic values

In-s [12.5K]

Answer : The temperature in kelvins is, $T>1108.695K$

Explanation : Given,

$\Delta H$ = 178.5 KJ/mole = 178500 J/mole

$\Delta S$ = 161.0 J/mole.K

Gibbs–Helmholtz equation is :

$\Delta G=\Delta H-T\Delta S$

As per question the reaction is spontaneous that means the value of $\Delta G$ is negative or we can say that the value of $\Delta G$ is less than zero.
