Answer:

CO2; succinyl-SCoA

Explanation:

Citric acid cycle, also called Krebs cycle is the second stage of aerobic cellular respiration, which occurs in the mitochondrion. The kreb's cycle is made up of 7 distinct steps, with each involving series of enzymatic reactions.

According to this question, step 3 and 4 of the citric acid cycle involves an oxidation and decarboxylation reaction to produce 2 molecules of carbon dioxide (CO2) and a 4-carbon compound called succinyl group. A coenzyme A binds to the succinyl group to form succinyl-SCoA.

Answer: 4.48 or 4.47

We are given:

M1 = 3 Molar        V1 = 80 mL

M2 = x Molar        V2 = 100 mL

Finding the molarity:

We know that:

M₁V₁ = M₂V₂

where V can be in any units

(3)(80) = (x)(100)

x = 240/100                                          [dividing both sides by 100]

x = 2.4 Molar

17 × ( 2 × 16 ) = 17 × 32 = 544 grams

[tex]p_2=2.655kPa[/tex]

Explanation:

Hello there!

In this case, according to the Dalton's law, which states that the total pressure is equal the sum of the pressures of the gases in the mixture, we write the following for this system:

[tex]P_T=p_1+p_2[/tex]

Thus, we solve for the partial pressure of the gas #2 as shown below:

[tex]p_2=P_T-p_1\\\\p_2=5kPa-2.345kPa\\\\p_2=2.655kPa[/tex]

Explanation:

Pb(NO3)2 + 2NaI 2NaNO3 + PbI2

To see the coefficients of NaI in the given reaction we need to balance the reaction first. The coefficient for Nal once the equation is balanced is 2. the correct option is option B.

Balanced equation is the one where the number of atoms of each species is same on reactant and product side. In balanced equation mass can neither be created nor be destroyed.

The unbalanced equation is

[tex]\rm Pb(NO_{3})_{2}+ Nal\rightarrow NaNO_{3} + PbI_{2}[/tex]

The atoms of Pb on reactant and product side is 1 so Pb is balanced.

The atoms of N is 2 on reactant and 1 on product side so balance it as

[tex]\rm Pb(NO_{3})_{2}+ Nal\rightarrow 2 NaNO_{3} + PbI_{2}[/tex]

The atoms of O is 6 on reactant and 6 on product side so it is balanced

The atoms of I is 1 on reactant and 2 on product side so balance it as

[tex]\rm Pb(NO_{3})_{2}+2 Nal\rightarrow 2NaNO_{3} + PbI_{2}[/tex]

The atoms of Na on reactant and product side is 2 so Na is balanced.

Now all the elements are balanced

Therefore, the coefficient for Nal once the equation is balanced is 2. the correct option is option B.

Answer:

4

Explanation:

so first write the balance equation

Ca+2H2O---->Ca(OH)2 + H2

then use molar ratio of H2O and Ca

which is 2:1 so if there are 2 moles of ca there will be 4 moles as you times it by 2. like this

Ca:H2O

1:2

2:4

Answer:

600 mL

Explanation:

molarity 1 * volume 1 = molarity 2 * volume 2. So this means 12 * 250 = 3000 and divide that by 5 to get 600 mL.

Explanation:

Mathematically, Ohm's law is given by :

V = IR

Where

V is voltage

I is current

R is resistance

The electric power of an electrical appliance is given by:

P = VI

Wattage = VI

Resistance, [tex]R=\dfrac{V}{I}[/tex]

Current, [tex]I=\dfrac{V}{R}[/tex]

Hence, this is the required solution.

Answer:

C)12.09 Ampere

Explanation:

V= IR

Where I= current of the system

R= resistance= 0.67 ohm

V= potential difference=8.1 volts

Substitute the values

8.1= I× 0.67

I= 8.1/0.67

=12.09 Ampere

Answer:

Because Sulphuric acid(H2SO4) is one of the substance which have a very high vigourous reaction if mix with chemicals thats why we take the same sulphuric acid but having lighter effects known to be as Dil.Sulphuric And so it is generally use for precaution while during experimentations Thats why we use it.

Explanation:

A blue light is shined on objects X and Y. Object X appears to be blue, and object Y appears to be black when Object X reflects blue light, and object Y absorbs blue light. Hence option B is correct.

Visible light spectrum is nothing but the range of wavelength of radiation from 4000 angstrom to 7000 angstrom(Violet to Red). light is a energy packet. Every Photon having different wavelength travels with same velocity c (velocity of light). When we focus numbers of colors from visible spectrum to a point, that point appears as a white light. hence white light is composed of numbers of Colors in it.

When we pass white light through a prism, as white light enters in the prism all the colors having different wavelength travels with different velocity in the prism due to that there is separation of colors from the white light. Therefore we get different colors of white light in the prism this phenomenon is know as dispersion of light.

Light can be reflected, absorbed, transmitted diffracted and scattered etc.

α + β + ν = 1 where α, β, ν are coefficient of absorption, reflection and transmission.

When any object appears to be black it means that radiation has been absorbed by that body, it has high absorption coefficient. and when a body appears to be colored, it means that object has reflected the particular color, it having high reflection coefficient.

Hence option B is correct.

Explanation:

Answer:

132.53 J/kg.°C

Explanation:

Applying,

Q = cm(t₂-t₁)................ Equation 1

Where Q = amount of heat, c = specific heat capacity of platinum metal, m = mass of platinum metal, t₁ = initial temperature, t₂ = Final temperature.

Make c the subeject of the equation

c = Q/m(t₂-t₁).............. Equation 2

From the question,

Given: Q = 5.7 J. m = 18.7 g = 0.0187 kg, t₁ = 21.2°C, t₂ = 23.5°C

Substitute these values into equation 2

c = 5.7/[0.0187×(23.5-21.2)]

c = 5.7/0.04301

c = 132.53 J/kg.°C

Answer:

"500 Joule/sec" is the right answer.

Explanation:

The given values are:

Force,

F = 1000 N

Velocity,

s = 10 m

Time,

t = 20 s

Now,

The power will be:

=  [tex]\frac{Force\times Velocity}{Time}[/tex]

On putting the values, we get

=  [tex]\frac{1000\times 10}{20}[/tex]

=  [tex]\frac{10000}{20}[/tex]

=  [tex]500 \ Joule/sec[/tex]

Answer:

48 °C

Explanation:

q = 90J

m = 15 g

C = 0.126 J/gºC

q = mct

90 = (15)(0.126)t

t = 47.62 °C = 48 °C

Answer:

Explanation:

Formula

E = m * c * Δt

Δt is what you seek.

Givens

E = 90 joules

m = 15 grams

c   = 0.126

Solution

90 = 15 * 0.126 * Δt         Divide by 15

90/15 = 15/15 * 0.126 * Δt

6 = 0.126 * Δt                  Divide by 0.126

6/0.126 = Δt

47.619 = Δt

Δt = 48 oC
