Answer:

1) The correct answer is option C.

2) the correct answer is option C.

Explanation:

1) Molecular formula of glucose = $C_6H_{12}O_6$

Number of carbon atoms in single molecule = 6

Number of carbon atoms in 3 molecule of glucose :

$\frac{6}{1}\times 3=18 atoms$ of carbon

There are 18 carbon atoms in the 3 molecules of glucose.

2) Homogeneous mixture is the mixture in which components are evenly distributed throughout the mixture. The shape and size of the particles are identical in the mixture.

Heterogeneous mixture is the mixtures in which component are unevenly distributed throughout the mixture. The shape and size of the particles are not identical in the mixture.

Air is the mixture of gases with 78% of nitrogen gas, 21% of oxygen gas and remaining 1 % are other gases. Air is a homogeneous mixture of different gases.

Where as water, oxygen , alcohol are pure substances.

Which statements describe the six elements found in all living things? Check all that apply.

vovangra [49]

Answer:

Carbon is the basis of all living things

Nitrogen is found in certain foods

Oxygen and hydrogen combine with each other to form water

Carbon, oxygen, hydrogen, nitrogen, phosphorus and sulfur are found in organic compounds

Explanation:

We are all made up of mainly three elements, Carbon, Hydrogen, and Oxygen. These three elements are found in every living organism on our planet, and along with a few trace elements, they make up all the nutrients we take in and use to build our bodies and survive.

Nitrogen is primarily found in meats, and this is because nitrogen is a key element in amino acids (which are used to build proteins), however we cannot directly assimilate nitrogen from the air, so we have to assimilate it through amino acids already synthesized in plants, or in proteins found in meat.

The chemical formula for water is H₂O. Seeing the chemical formula, it is obvious that hydrogen and oxygen are the only elements in the water molecule.

In our bodies, we use phosphorus to form our skeleton and help maintain it, sulfur and nitrogen can be found in some amino acids, and carbon, hydrogen and oxygen can be found in carbohydrates, lipids and proteins.

Which of the following shows the conservation of mass during cellular respiration? 3 CO2 3 H2O energy → 3 C6H12O6 3 O2 6 CO2 6 H

Thepotemich [5.8K]

The reaction that has been, following the law of conservation of mass has been $\rm C_6H_1_2O_6\;+\;6\;O_2\;\rightarrow\;6\;CO_2\;+\;6\;H_2O\;+\;Energy$ .

The law of conservation has been given in the chemical reaction that there has been no loss or gain of the mass and energy.

The law of conservation has been evident when there has been an equal number of atoms of each element on the product and the reactant side.

<h3 /><h3>Conservation of mass in Cellular respiration</h3>

The following reactions have been identified as:

$\rm 3\;CO_2\;+\;3\;H_2O\;+\;Energy\;\rightarrow\;3\;C_6H_1_2O_6$

Carbon atoms

Reactant = 3

Product = 18

Oxygen atoms

Reactant = 9

Product = 18

Hydrogen atoms

Reactant = 6

Product = 36

The number of atoms is not equal on the product and reactant side, thus not follows the law of conservation of mass.

$\rm 3\;O_2\;+\;6\;CO_2\;+\;6\;H_2O\;+\;Energy\;\rightarrow\;C_6H_1_2O_6\;+\;6\;O_2$

Carbon atoms

Reactant = 6

Product = 6

Oxygen atoms

Reactant = 24

Product = 18

Hydrogen atoms

Reactant = 12

Product = 12

The number of atoms is not equal on the product and reactant side, thus not follows the law of conservation of mass.

$\rm C_6H_1_2O_6\;+\;6\;O_2\;\rightarrow\;6\;CO_2\;+\;6\;H_2O\;+\;Energy$

Carbon atoms

Reactant = 6

Product = 6

Oxygen atoms

Reactant = 18

Product = 18

Hydrogen atoms

Reactant = 12

Product = 12

The number of atoms is equal on the product and reactant side, thus follows the law of conservation of mass.

$\rm 6\;H_2O\;+\;C_6H_1_2O_6\;\rightarrow\;6\;O_2\;+\;Energy$

Carbon atoms

Reactant = 6

Product = 0

Oxygen atoms

Reactant = 12

Product = 12

Hydrogen atoms

Reactant = 24

Product = 0

The number of atoms is not equal on the product and reactant side, thus not follows the law of conservation of mass.

Thus, the reaction that has been following the law of conservation of mass has been $\rm C_6H_1_2O_6\;+\;6\;O_2\;\rightarrow\;6\;CO_2\;+\;6\;H_2O\;+\;Energy$ .

A loaded coal wagon with a total mass of 20 000 kg is pushed by a force of 300 000 N. What was the wagon’s acceleration?

AlexFokin [52]

Answer:

Explanation:

The acceleration of an object given it's mass and the force acting on it can be found by using the formula

$a = \frac{f}{m} \\$
