Many repeating, simple subunits are joined together. What is the most likely
O a halogen
O a polymer
O a monomer
an amino acid

Answers

Answer:

O a polymer

Explanation:

When many repeating simple subunits are joined together, this results into a polymer.

The simplest unit or smallest unit of any substance is called a monomer. When many units of a monomer joins together, a polymer results.

For proteins, the monomeric unit is amino-acid. When they combine they form longer chain molecules called proteins. For carbohydrates, the monomeric unit is called glucose. When they are combined they give us a wide range of carbohydrate molecules.

If a sample of 2 moles of nitric oxide gas was reacted with excess oxygen, how many moles of nitrogen dioxide would be produced?

Answers

Answer:

If a sample of 2 moles of nitric oxide gas was reacted with excess oxygen, 2 moles of nitrogen dioxide would be produced.

Explanation:

The balanced reaction is:

2 NO + O₂ → 2 NO₂

By stoichiometry of the reaction (that is, the relationship between the amount of reagents and products in a chemical reaction), the following amounts of each compound participate in the reaction:

NO: 2 molesO₂: 1 moleNO₂: 2 moles

The limiting reagent is one that is consumed first in its entirety, determining the amount of product in the reaction. When the limiting reagent is finished, the chemical reaction will stop.

The limiting reagent is one that is consumed first in its entirety, determining the amount of product in the reaction. When the limiting reagent is finished, the chemical reaction will stop. By reaction stoichiometry, if a sample of 2 moles of nitric oxide gas was reacted with excess oxygen, 2 moles of nitrogen dioxide would be produced.

Excess reagents are reactants that do not completely vanish after the reaction is complete. Moles of nitrogen dioxide produced is 2 moles.

What is limiting and excess reagents?

In a chemical reaction when the reactant is left and is not completely consumed after the formation of the product is called excess reagents.

The reactants or the reagents that get consumed first in the reaction and limit the product formation is called limiting reagent.

The balanced chemical reaction can be shown as,

[tex]\rm 2NO + O_{2} \rightarrow 2NO_{2}[/tex]

The stoichiometry coefficient gives the moles of the reactant and the products as,

Moles of nitric oxide = 2 molesMoles of oxygen = 1 moleMoles of nitrogen dioxide = 2 moles

According to the reaction if the 2 moles of nitric oxide reacts with an excess of the oxygen gas then 2 moles of [tex]\rm NO_{2}[/tex] is produced.

Therefore, moles of nitrogen dioxide produced is 2 moles.

An astronomer is studying two stars that are the same distance from the earth. Star X appears brighter than Star Y. Which statement best explains this observation

Answers

Explanation:

The brightness of star depends upon two factors

1. Luminosity

2. Distance from the earth.

Luminosity is the amount of energy emitted by the star in unit, greater the luminosity greater will be the brightness. However, Stars that are closer to Earth, but fainter, could appear brighter than far more luminous ones that are far away.

Therefore, star can either be closer to earth or more luminous than star Y or both.

A) 0.0°C
B) 40°C
C) 80°C
D) 101.3°C

Answers

The water will boil at C) 80°C

Further explanation

Given

Vapour pressure of water = 47 kPa

Required

Boiling point of water

Solution

We can use the Clausius-Clapeyron equation :

[tex]\tt ln(\dfrac{P_1}{P_2})=\dfrac{-\Delta H_{vap}}{R}(\dfrac{1}{T_1}-\dfrac{1}{T_2})[/tex]

Vapour pressure of water at boiling point 100°C=101.325 kPa

ΔH vap for water at 100°C=40657 J/mol

R = 8.314 J/mol K

T₁=boiling point of water at 101.325 kPa = 100+273=373 K

Input given values :

[tex]\tt ln\dfrac{101.325}{47}=\dfrac{-40657}{8.314}(\dfrac{1}{373}-\dfrac{1}{T_2})\\\\0.7682=4890.1852(\dfrac{1}{373}-\dfrac{1}{T_2})\\\\0.0001571=(\dfrac{1}{373}-\dfrac{1}{T_2})\\\\\dfrac{1}{T_2}=0.00283\rightarrow T_2=353~K=80^oC[/tex]

How much heat is released when the temperature of 60g water decreases from 75 Celsius to 27 Celsius?


Answers

Answer:

The heat released when the temperature of 60 g of water decreases from 75 degrees Celsius to 27 degrees Celsius is -12,049.92 J.

Explanation:

Calorimetry is the measurement and calculation of the amounts of heat exchanged by a body or a system.

Sensible heat is the amount of heat that a body absorbs or releases without any changes in its physical state or phase change. Sensible heat is measured by the expression:

Q = c * m * ΔT

Where Q is the heat exchanged by a body of mass m, constituted by a substance of specific heat c and where ΔT is the variation in temperature.

In this case:

Q= ?c= 4.184 [tex]\frac{J}{g*C}[/tex]m= 60 gΔT= Tfinal - Tinitial= 27 C - 75 C= - 48 C

Replacing:

Q= 4.184 [tex]\frac{J}{g*C}[/tex] *60 g* (-48 C)

Q= -12,049.92 J

The heat released when the temperature of 60 g of water decreases from 75 degrees Celsius to 27 degrees Celsius is -12,049.92 J.

A student uses a magnet to move a 0.0 25 KG metal ball the magnet exerts a force of five in which causes the body to begin moving what is the acceleration of the ball when it begins to move

Answers

Answer:

The acceleration of the ball when it begins to move is 200 m/s²

Explanation:

The given parameters are;

The mass of the metal ball, m = 0.025 kg

The force exerted by the magnet on the ball, F = 5 N

From Newton's second law, F = m × a

Where;

a = The acceleration of the ball

Therefore, by substitution, we have;

5 = 0.025 × a

a = 5/0.025 = 200 m/s²

The acceleration of the ball when it begins to move = 200 m/s²

The type of bonding which  can be described as a "cooperation" is covalent bonding as there is sharing of electrons.

What is covalent bonding?

Covalent bonding is defined as a type of bonding which is formed by the mutual sharing of electrons to form electron pairs between the two atoms.These electron pairs are called as bonding pairs or shared pair of electrons.

Due to the sharing of valence electrons , the atoms are able to achieve a stable electronic configuration . Covalent bonding involves many types of interactions like σ bonding,π bonding ,metal-to-metal bonding ,etc.

Sigma bonds are the strongest covalent bonds while the pi bonds are weaker covalent bonds .Covalent bonds are affected by electronegativities of the atoms present in the molecules.Compounds having covalent bonds have lower melting points as compared to those with ionic bonds.

B. Cl₂ + NaBr → NaCl + Br₂

Explanation:

The single replacement chemical equation that is unbalanced is Cl₂ + NaBr → NaCl + Br₂.

A look at the equation and you will discover that the chlorine on the reactant side is not balanced with the one on the product side. The chlorine at the reactant side has 2 atoms of chlorine but just 1 atom of chlorine in the product side. Therefore, it is unbalanced.   Also, you will discover that the bromine on the reactant side is not balanced with the one at the product side. The bromine on the reactant side has 1 atom of bromine while at the product side, it has 2 atoms. Therefore, it is unbalanced.

For a chemical equation to be balanced, the number of atoms and molecules at the reactant side must be equal to the number of atoms and molecules at the product side.  A single replacement reaction takes place whenever there is a replacement of one element by another element in a compound during a chemical reaction.
