Answer:

The mass defect of a deuterium nucleus is 0.001848 amu.

Explanation:

The deuterium is:

[tex]^{A}_{Z}X \rightarrow ^{2}_{1}H [/tex]  

The mass defect can be calculated by using the following equation:

[tex]\Delta m = [Zm_{p} + (A - Z)m_{n}] - m_{a}[/tex]

Where:

Z: is the number of protons = 1

A: is the mass number = 2      

[tex]m_{p}[/tex]: is the proton's mass = 1.00728 amu  

[tex]m_{n}[/tex]: is the neutron's mass = 1.00867 amu

[tex]m_{a}[/tex]: is the mass of deuterium = 2.01410178 amu

Then, the mass defect is:

[tex]\Delta m = [1.00728 amu + (2- 1)1.00867 amu] - 2.01410178 amu = 0.001848 amu[/tex]

Therefore, the mass defect of a deuterium nucleus is 0.001848 amu.

To see which reaction will happen we need to see the reactivity series of metals which shows the order of reactivity of metals, which displaces which. So option c is the correct option

Displacement reaction is a reaction in which one atom replaces other atom from a molecule on the basis of reactivity strength. It is done by following reactivity series which states the increase order of reactivity of metals.

So in C option Li is a more reactive metal than Zn so Li can displace Zn from the Zinc carbonate Whereas in other option Platinum, Copper, Manganese are less reactive than Iron in Ferric chloride, Potassium in Potassium nitrate and calcium in  Calcium oxide according to reactivity series. So In only option c, reaction will go in forward direction.

Answer:

ΔH 263 < ΔH 273

Explanation:

From the given information

According to Kirchoff law:

[tex]\Delta H_2 = \Delta \ H_1 + \Delta \ (c_p) ( \Delta T)[/tex]

[tex]\Delta H_2 = \Delta \ H_1 + (76-37) \times ( 273 - 263)[/tex]

[tex]\Delta H_2 = \Delta \ H_1 + (39) \times (10)[/tex]

[tex]\Delta H_2 = \Delta \ H_1 + 390[/tex]

Thus, [tex]\Delta H_2[/tex] at 273 is greater than [tex]\Delta \ H_1[/tex] at 263

∴

ΔH 263 < ΔH 273

When two equal forces act in opposite directions the result is that the forces are balanced and there is no motion. The process of moving or changing position. When one force is stronger than the other the result is motion.

An force results when one force is stronger than other forces and the motion of an object is affected is unbalanced force.

A force is an influence in physics that can change the motion of an object. A force can cause a mass object to change its velocity, or accelerate.

The forces are balanced if the people on each side of the rope pull with equal strength but in opposite directions.

As a result, there is no movement. Forces that are in balance can cancel each other out. The object does not move when there is a balanced force.

Forces out of balance, If one force is stronger than the others and their effects do not cancel out, the forces are unbalanced. Unbalanced forces alter motion, speed, and/or direction. A greater force results in a greater change in motion.

Thus, the answer is unbalanced force.

Answer:

H+ (aq)  +    ClO- (aq)  --->   HClO(aq)  

Explanation:

The net ionic reaction equation is a chemical equation that explicitly shows only the particular ions that undergo a chemical change in the course of a given reaction.

In this particular reaction, the molecular reaction equation is shown as follows;

HNO3(aq) + NaOCl(aq) -----------> NaNO3(aq) + HOCl(aq)

Answer:

53.31g of FeCl3

Explanation:

The equation of the reaction is given as;

2Fe(s)  + 3Cl2(g) --> 2FeCl3(s)

From the stochiometry of the reaction;

2 mol   :    3 mol       :   2 mol

112g     :      213g      :     324.4g

Converting the masses given to moles;

Number of moles of Fe = mass / molar mass = 22.5 / 56 = 0.4018

Number of moles of Cl2 = mass / molar mass = 35 /  71 = 0.4930

In this reaction, the limiting reactant is Cl2

213 g of Cl2 produces 324.4g of FeCl3,

35g of Cl2 would produce xg of FeCl3

213 = 324.4

35 = x

x = (35 * 324.4) / 213 = 53.31g

Answer:

I'd say the most reasonable answer is perspective.

Explanation:

"Point of view" is about who is telling and sharing the details in what you are writing or reading. I'm not 100% sure because the word "perspective" doesn't seem like the right word to use, but it's better than the other two in my opinion.

Answer : The fraction represents the amount of an original sample of this element remaining after 6 days is [tex]\frac{1}{8}[/tex] .

Explanation :

Half-life = 2 days

Time = 6 days

Formula used:

[tex]N=N_o\times (\frac{1}{2})^{(\frac{t}{t_{1/2}})}[/tex]

where,

N = final amount

[tex]N_o[/tex] = initial amount

t = time

[tex]t_{1/2}[/tex] = half-life

Now putting all the given values in the above formula, we get:

[tex]N=N_o\times (\frac{1}{2})^{(\frac{6}{2})}[/tex]

[tex]\frac{N}{N_o}=(\frac{1}{2})^{(\frac{6}{2})}[/tex]

[tex]\frac{N}{N_o}=(\frac{1}{2})^3[/tex]

[tex]\frac{N}{N_o}=\frac{1}{8}[/tex]

Therefore, the fraction represents the amount of an original sample of this element remaining after 6 days is [tex]\frac{1}{8}[/tex] .

Enzyme lactase catalyzes the hydrolysis of the glycosidic bond of lactose to form galactose and glucose.

Lactase can be described as an enzyme produced by many organisms. Lactase is located in the small intestine of humans and other mammals. It is essential to accomplish the digestion of milk and it breaks down lactose that gives milk its sweetness.

A person with a deficiency of lactase, and who consume dairy products, may experience the symptoms of lactose intolerance. Lactase is a part of the β-galactosidase family of enzymes and is a glycoside hydrolase involved in the hydrolysis of lactose into constituent galactose and glucose monomers.

The β-glycosidic bond in D-lactose in metabolism is hydrolyzed to form D-galactose and D-glucose, which can be absorbed into the bloodstream. The optimum temperature of the human lactase is about 37 degrees Celcius and the optimum pH of the human lactase is equal to 6.
