What is the y-intercept of the function f(x) = -x+ ?
2 름

Answers

Answer 1
The y intercept will be +2
Answer 2

The points on the y-intercepts are (0,y) whereas the point on the x-intercept are (x,0). Here the y-intercept of the function f(x) = -x + 2 is 2.

What is y-intercept?

When the line touches the y-axis, we can say that these are y-intercepts. The y-intercept can be found out when x = 0. This represents the point at which the graph crosses through the y-axis. The y-intercept can also be referred as y-value.

In order to find the intercepts of any function, we must find the coordinates of the point where the function intersects the x and y axis. This can also be done by equating the independent or dependent variable value as 0 and then finding out the other value.

Here the given function is:

f(x) = -x + 2

When we put x = 0, then

f(x) = -0 + 2 = 2

Thus the y-intercept is 2.

The equilibrium constant (K) for the reaction
2HCI(g) = H2(g) + Cl2(g)
is 4.17 x 10-34 at 25°C. What is the equilibrium constant for the reverse reaction at the same
temperature?
H2(g) + Cl2(g) = 2HCl(g)

Answers

Answer: The equilibrium constant for the reverse reaction at the same temperature is [tex]2.40 \times 10^{33}[/tex].

Explanation:

The given reaction equation is as follows.

[tex]2HCl(g) \rightleftharpoons H_{2}(g) + Cl_{2}(g)[/tex] ... (1)

It's equilibrium constant (K) value is [tex]4.17 \times 10^{-34}[/tex].

Also, another reaction equation is as follows.

[tex]H_{2}(g) + Cl_{2}(g) \rightleftharpoons 2HCl(g)[/tex]

This is the reverse of equation (1). Hence, its equilibrium value is calculated as follows.

[tex]K' = \frac{1}{K}\\= \frac{1}{4.17 \times 10^{-34}}\\= 2.40 \times 10^{33}[/tex]

Thus, we can conclude that the equilibrium constant for the reverse reaction at the same temperature is [tex]2.40 \times 10^{33}[/tex].

2 moléculas de clorato de potasio (KClO3) forman 2 moléculas de cloruro de potasio (KCl) y 3 moléculas de oxígeno (O2

Answers

The complete question is as follows: 2 molecules of potassium chlorate (KClO3) form 2 molecules of potassium chloride (KCl) and 3 molecules of oxygen (O2). Write a balanced equation for this reaction?

Answer: The balanced chemical equation is [tex]2KClO_{3} \rightarrow 2KCl + 3O_{2}[/tex].

Explanation:

A balanced equation is defined as the equation which contains same number of atoms on both reactant and product side when a chemical reaction occurs.

Hence, when 2 molecules of potassium chlorate [tex](KClO_{3})[/tex] form 2 molecules of potassium chloride (KCl) and 3 molecules of oxygen [tex](O_{2})[/tex] then its balanced equation will be as follows.

[tex]2KClO_{3} \rightarrow 2KCl + 3O_{2}[/tex]

Here, number of atoms on the reactant side as as follows.

K = 2Cl = 2O = 6

Number of atoms on the product side are as follows.

K = 2Cl = 2O = 6

Since, the number of atoms on reactant side are equal to the number of atoms on product side. So, this reaction equation is balanced.

Thus, we can conclude that the balanced chemical equation is [tex]2KClO_{3} \rightarrow 2KCl + 3O_{2}[/tex].

Answer:

5.1 moles of P2O3 are required

Explanation:

Based on the reaction, 1 mole of diphosphorus trioxide, P2O3, reacts with 3 moles of water to produce 2 moles of phosphorous acid, H3PO3. That means the conversion factor is: 1mol P2O3 = 2mol H3PO3.

The moles of P2O3 required to produce 10.2mol H3PO3 are:

10.2mol H3PO3 * (1mol P2O3 / 2mol H3PO3) =

5.1 moles of P2O3 are required

PCl5 decomposes into PCl3 and Cl2 according to the equation above. A pure sample of Pcl5 is placed in a rigid, evacuated 1.00 L container. The initial pressure of the PCl5 is 1.00 atm. The temperature is held constant until the PCl5 reaches equilibrium with its decomposition products. The figures below show the initial and equilibrium conditions of the system.

As the reaction progresses toward equilibrium, the rate of the forward reaction

A) increases until it becomes the same as the reverse reaction rate at equilibrium

B) stays constant before and after equilibrium is reached

C) decreases to become a constant nonzero rate at equilibrium

D) decreases to become zero at equilibrium

Explanation:

At equilibrium, both forward and backward reactions take place with constant speed.

The reaction will never cease.

Due to this reason chemical equilibrium is called dynamic in nature.

At equilibrium:

the rate of forward reaction = rate of backward reaction

As the reaction progresses toward equilibrium, the rate of the forward reaction decreases to become a constant nonzero rate at equilibrium.

Answer is option C).

When a system is in a state of chemical equilibrium, neither the reactant concentration nor the product concentration changes over time, nor does the system exhibit any further changes in its attributes. Here the correct option is C.

The system reaches a condition of chemical equilibrium when the rate of the forward reaction equals the rate of the reverse reaction. The system is considered to be in a state of dynamic equilibrium when the concentrations of the reactants and products do not change further as a result of the equal rates of the forward and reverse processes.

Equilibrium is impacted by a number of variables, including temperature, pressure, and the system's concentration. Here at equilibrium the rate of the forward reaction decreases to become a constant nonzero rate at equilibrium.

Thus the correct option is C.

other due to
A proton attraction
B neutron attraction
C sharing of electrons
D opposite charges
<

Answers

Answer:

The correct option is option C

Explanation:

Loss or gain of electron(s) occurs in a type of attraction known as electrovalent or ionic attraction. In this type, there is transfer (or loss) of electron(s) from a metal atom to become positively charged while a nonmetal accepts (or gains) this electron to become negatively charged.

When this does not happen, two metal atoms can become attached by sharing the same electrons through a form of attraction known as covalent bonding. Here, the two atoms share electrons (known as shared pair) together to achieve there octet configuration on the outermost shell.

How many particles are in 13.5 grams of Beryllium ?

Recall that 1 mole of a substance contains 6.02 x 10^23 atoms.

Number of moles in 13.5 grams of Beryllium = mass/molar mass

Calculate the percentage of water of crystallisation in MgSO⁴ 7H²O

Answers

Answer:

Formula of EPSOM salt = MgSO4.7H2O

molecular mass of MgSO4.7H2O = atomic mass of Mg + atomic mass of S + 4 × atomic mass of O + 7 { 2 × atomic mass of H + atomic mass of O }

= 24 + 32 + 4× 16 + 7{ 2 × 1 + 16 } g/mol

= (24 + 32 + 64+ 126 ) g/mol

= 246 g/mol

molecular mass of total water = 7 × ( 2× atomic mass of H + atomic mass of O )

= 7 × 18 = 126 g/mol

now ,

% mass of H2O in EPSOM salt = {total molar mass of H2O/molar mass of Epsom salts }× 100

A solution of ammonia NH3(aq) is at equilibrium. How would the equilibrium

According to Le-chtelier's principle:

If there is any change in the variables of the reaction, then the equilibrium will shift in that direction of equilibrium to minimize the effect.

If we add more amount of [tex]NH_4^+[/tex] to the solution, more of the products will be present. But according to Le-chtelier's principle, to minimize this effect, the equilibrium will shift in the backward direction that in the direction of [tex]NH_3[/tex]
