if a car collides with a barrier and hit with a hundred 50 Newtons of force how much force does the barrier put in the car?​

Answers

Answer 1

Answer: 50 Newtons

Explanation:

Due to newtons third law of motion for every action there is an equal and opposite reaction or in this case the equal and opposite amount of force applied so the same 50 N is applied on the car by the barrier

"pure water does not conduct electricity. But some tap water probably can. Which best explains this?" a . Tap water is H20 b . Pure water is H20 c . Some tap water has minerals, such as iron in it.

Answers

Explanation:

"pure water does not conduct electricity. But some tap water probably can."

The reason why pure water does not conduct electricity is due to the absence of mineral and metal containing salts. Pure water is made up of only Hydrogen and oxygen atom as represented by the formula; H2O

Tap water on the other hand are most likely able to conduct electricity due to the presence of these ions. They may arise from impurities or during treatment processes.

The correct options are;

b . Pure water is H2O

c . Some tap water has minerals, such as iron in it.

An alpha particle is composed of He2+ ions?
true or false​

Answers

Answer: The given statement is False.

Explanation:

Alpha particle is a helium nuclei.

Alpha particles are produced when a larger nuclei decays into smaller nuclei in radioactive decay. Alpha particles have mass number and atomic number as 4 and 2 respectively.

General representation of alpha decay :

[tex]^A_Z\textrm{X}\rightarrow ^{A-4}_{Z-2}\textrm{Y}+^4_2\textrm{He}[/tex]

Thus the given statement that alpha particle is composed of [tex]He^{2+}[/tex] ions is False.

The statement of [tex]\rm He^2^+[/tex] ions has formed the alpha particles is true.

Alpha particles are particles that have been similar to the He-4, with the presence of two protons and two neutrons. The alpha particles have the absence of electrons and have been formed during the alpha decay.

[tex]\rm He^2^+[/tex] has been the ion of He with the positive charge indicating the loss of 2 electrons. Thus, in [tex]\rm He^2^+[/tex], there has been 2 protons, 2 neutrons, and 0 electrons.

The atomic configuration of [tex]\rm He^2^+[/tex]has been similar to the alpha particles. Thus, the statement stating, "the alpha particles to be composed of [tex]\rm He^2^+[/tex]ions " is True.

if 13 moles of Fe react, what is the mass of FeS produced?​

Answers

Answer:

1144 g of FeS

Explanation:

We'll begin by writing the balanced equation for the reaction. This is illustrated below:

Fe + S —> FeS

From the balanced equation above,

1 mole of Fe reacted to produce 1 mole of FeS.

Therefore, 13 moles of Fe will also react to produce 13 moles of FeS.

Finally, we shall determine mass of 13 moles of FeS. This can be obtained as follow:

Mole of FeS = 13 moles

Molar mass of FeS = 56 + 32

= 88 g/mol

Mass of FeS =?

Mass = mole × molar mass

Mass of FeS = 13 × 88

Mass of FeS = 1144 g

Therefore, 1144 g of FeS were obtained from the reaction.

Mr Singh is cooking using wo pans of oiling water. Both pans are made of steel, but one pan has a much thicker base than the other pan. Explain how energy is transferred through the metal pans. Write about particles in your answer.

Answers

Answer:

See explanation

Explanation:

When either pan is heated, energy is transferred via conduction. Conduction is the process by which heat is transferred through a material, the average position of the particles remaining the same.

When the pans are heated, the particles in each pan vibrate faster and transfer this energy rapidly to neighboring particles.

The pan with a thicker base has more particles in it than the pan with lighter weight base. Note that, The rate of heat transfer is inversely proportional to the thickness of the material in question. Hence, the thicker the base, the more the number of particles present and the longer the time it takes for the food to cook.

12.0 g NaHSO4 (MM: 120.1 g/mol) is dissolved in water to make a 2.00 L solution. What is the molarity of the resulting NaHSO4 solution?

Answers

Answer:

0.05 M

Explanation:

First we convert 12 g of NaHSO₄ into moles, using the given molar mass:

12 g NaHSO₄ ÷ 120.1 g/mol = 0.10 mol NaHSO₄

We can now calculate the molarity of the resulting solution, using the calculated number of moles and the given volume:

Molarity = moles / litersMolarity = 0.10 mol / 2.00 L = 0.05 M

Answer:

The molarity of the resulting NaHSO₄ solution is 0.05 [tex]\frac{moles}{liter}[/tex]

Explanation:

Molarity or Molar Concentration is the number of moles of solute that are dissolved in a certain volume.

The molarity of a solution is calculated by dividing the moles of the solute by the volume of the solution:

[tex]Molarity=\frac{moles of solute}{volume}[/tex]

Molarity is expressed in units [tex]\frac{moles}{liter}[/tex].

Molar mass is the amount of mass that a substance contains in one mole. Being the molar mass of the compound NaHSO₄ equal to 120.1 g/mole, then the number of moles that 12 grams contain is calculated by:

[tex]12 g*\frac{1 mole}{120.1 g} = 0.1 moles[/tex]

And being 2 L the volume of the solution, then replacing in the definition of molarity you get:

[tex]Molarity=\frac{0.1 moles}{2 L}[/tex]

Molarity= 0.05 [tex]\frac{moles}{liter}[/tex]

The molarity of the resulting NaHSO₄ solution is 0.05 [tex]\frac{moles}{liter}[/tex]

Calculate the concentration of a 220 g solution of calcium chloride (CaCl2) that has a volume of 11 L

Answers

Answer: The concentration of the solution is 0.18 M

Explanation:

Molarity of a solution is defined as the number of moles of solute dissolved per liter of the solution.

[tex]Molarity=\frac{n}{V_s}[/tex]

where,

n = moles of solute

[tex]V_s[/tex] = volume of solution in L

moles of [tex]CaCl_2[/tex] = [tex]\frac{\text {given mass}}{\text {Molar mass}}=\frac{220g}{111g/mol}=1.98mol[/tex]

Now put all the given values in the formula of molality, we get

[tex]Molarity=\frac{1.98mol}{11L}=0.18M[/tex]

Therefore, the concentration of the solution is 0.18 M

What does what does c6h12o6+6o2→6co2+6h2o+energy equal to?

Answers

Answer: c6h12o6+6o2→6co2+6h2o= C6H12O6 + 6O2 -> 6CO2 + 6H2O Yields 2755 kJ/mole of glucose. The reverse of this reaction – combing carbon dioxide and water to make sugar is known as photosynthesis. Photosynthesis is the process responsible for storing all the energy we extract from fossil fuels, crops, and all of our food. We will also see that it is part of a globally important cycle affected by our consumption of fossil fuels. Photosynthesis How is photosynthesis able to run the reaction above in the reverse direction? Somehow it must come up with 2755 kJ of energy to make each mole of glucose. Where does that energy come from? The short answer: photons of sunlight. The long answer: When the pigment chlorophyll inside the chloroplasts of a photosynthetic organism (phytoplankton, trees, other plants) absorbs sunlight, it becomes energetically ‘excited’ and grabs the hydrogen atoms away from a water molecule, leaving the oxygen atoms to escape as O2 gas. This is called ‘splitting water.’ The hydrogen atoms are then split into their component protons and electrons. The electrons are used to reduce carbon dioxide, in a series of many steps requiring more absorption of sunlight by chlorophyll, to glucose. When carbon dioxide receives those electrons, the extra negative charge attracts protons from elsewhere, creating hydrogen atoms attached to the carbon atom. This process is called reduction. When those reduced carbon dioxide molecules are combined together in a larger molecule, the result is glucose. This ‘combing together’ of small molecules requires an input of energy, which is provided by the ATP molecules made by the protons diffusing through the membrane of the chloroplast. The ATP molecule is simply a molecule that biology uses to store energy for later use. In this case, the mechanical energy created by the protons diffusing across the membrane turns a sort of molecular turbine that smashes together its precursors.

A mixture of helium, nitrogen and oxygen has a total pressure of 781 mmHg. The partial pressure of helium is 331 mmHg, and the partial pressure of nitrogen is 222 mmHg. What is the partial pressure (in mmHg) of oxygen in the mixture?

Answers

Answer:

Partial pressure of O₂ =  228 mmHg

Explanation:

The mixture is made of three gases, He, N₂ and O₂.

Total pressure of it, is 781 mmHg.

There is a law from gases, that indicates the sum of partial pressures of each gas in a mixture will be the total pressure of the system. In conclussion:

Partial pressure of He + Partial pressure of N₂ + Partial pressure of O₂ = Total pressure.

331 mmHg + 222 mmHg + Partial pressure of O₂ = 781 mmHg.

Partial pressure of O₂ = 781 mmHg - 331 mmHg - 222 mmHg

Partial pressure of O₂ =  228 mmHg
