if hydrochloride tablets and eno combine what will the reaction​

Answer:

184.62 ml

Explanation:

Let [tex]p_1, v_1,[/tex] and [tex]T_1[/tex] be the initial and [tex]p_2, v_2,[/tex] and [tex]T_2[/tex] be the final pressure, volume, and temperature of the gas respectively.

Given that the pressure remains constant, so

[tex]p_1=p_2[/tex] ...(i)

[tex]v_1[/tex] = 200 ml

[tex]T_1= 26 ^{\circ}C = 273+26 =299[/tex] K

[tex]T_2= 3 ^{\circ}C = 273+3 =276[/tex] K

From the ideal gas equation, pv=mRT

Where p is the pressure, v is the volume, T is the temperature in Kelvin, m is the mass of air in kg, R is the specific gas constant.

For the initial condition,

[tex]p_1v_1=mRT_1 \\\\mR= \frac{p_1v_1}{T_1}\cdots(ii)[/tex]

For the final condition,

[tex]p_2v_2=mRT_2 \\\\mR= \frac{p_2v_2}{T_2}\cdots(iii)[/tex]

Equating equation (i), and (ii)

[tex]\frac{p_1v_1}{T_1}=\frac{p_2v_2}{T_2}[/tex]

[tex]\frac{v_1}{T_1}=\frac{v_2}{T_2}[/tex]  [from equation (i)]

[tex]v_2=\frac{T_2}{T_1} \times v_1[/tex]

Putting all the given values, we have

[tex]v_2=\frac{276}{299} \times 200 = 184.62 \; ml[/tex]

Hence, the volume of the gas at 3 degrees Celsius is 184.62 ml.

Answer:

The appropriate speed will be "20 m/s".

Explanation:

The given values are:

Wavelength,

λ = 5.0 M

Frequency,

f = 4 Hz

Now,

The speed of the wave will be:

⇒ [tex]V=f\times \lambda[/tex]

On putting the values, we get

⇒     [tex]=4\times 5.0[/tex]

⇒     [tex]=20 \ m/s[/tex]

Answer:

C

Explanation:

The kinetic energy of a body is the energy due to the motion of a body. It is mathematically given as;

 Kinetic energy  = [tex]\frac{1}{2}[/tex] m v²

m is the mass of the body

v is the velocity

 Now, let us find the K.E from the given choices;

Option C will have the greatest kinetic energy;

         mass  = 0.14kg , v  = 40m/s

 Kinetic energy  = [tex]\frac{1}{2}[/tex] x 0.14 x 40²   = 112J

Answer:

Empirical formula is C₅H₁₂O

Molecular formula = C₅H₁₂O

Explanation:

Given data:

Percentage of hydrogen =13.75%

Percentage of carbon = 68.11%

Percentage of oxygen = 18.15%

Empirical formula = ?

Solution:

Number of gram atoms of H = 13.75 / 1.01 = 13.6

Number of gram atoms of O = 18.15 / 16 = 1.13

Number of gram atoms of C = 68.11 / 12 = 5.68

Atomic ratio:

            C                      :      H               :         O

           5.68/1.13           :     13.6/1.13     :       1.13/1.13

            5                      :        12          :        1

C : H : O = 5 : 12 : 1

Empirical formula is C₅H₁₂O.

Molecular formula:

Molecular formula = n (empirical formula)

n = molar mass of compound / empirical formula mass

Empirical formula mass :

5×12 + 12×1.01 + 16×1 = 88.12 g/mol

n = 88.17/ 88.12

n = 1

Molecular formula = n (empirical formula)

Molecular formula = 1 (C₅H₁₂O)

Molecular formula = C₅H₁₂O

Answer:

sun shine

Explanation:

Sunlight reaches Earth's atmosphere and is scattered in all directions by all the gases and particles in the air. Blue light is scattered more than the other colors because it travels as shorter, smaller waves. This is why we see a blue sky most of the time

Answer:

Sunlight

Explanation:

Sunlight reaches Earth's atmosphere and is scattered in all directions by all the gases and particles in the air. Blue light is scattered more than the other colors because it travels as shorter, smaller waves. This is why we see a blue sky most of the time. Blue light is scattered in all directions by the tiny molecules of air in Earth's atmosphere. Blue is scattered more than other colors because it travels as shorter, smaller waves. This is why we see a blue sky most of the time. ... Also, the surface of Earth has reflected and scattered the light.

as I guess it is last statement

Answer:

Mass = 1080.26 g

Explanation:

Given data:

Number of moles of LaPO₄ = 4.56mol

Mass in gram = ?

Solution:

Formula:

Number of moles = mass/molar mass

Molar mass of LaPO₄ = 236.9 g/mol

by putting values,

4.56 mol = mass/ 236.9 g/mol

Mass = 4.56 mol  × 236.9 g/mol

Mass = 1080.26 g

class???????????? and which chapter?????????

Answer:

This question is incomplete

Explanation:

This question is incomplete because of the absence of the drawing  referred to in the question.

However, each option refers to a particular respiratory system and with the organs and the tissues mentioned here one can eventually identify which option is correct when the drawing is available.

A) The system described here is the cardiovascular system (or the circulatory system). This system involves the heart, blood vessels and the blood (which are what help in the transport of the materials mentioned in the question).

B) The system described here is the digestive system. This system involves the gastrointestinal tract and organs (that assist in the production/secretion or storage of chemicals that breakdown food into smaller pieces) such as the mouth, esophagus, stomach, small intestine, large intestine, rectum and the anus.

C) The system described here is the skeletal system. This system involves all the bones and joint in the body (the skeleton) which also helps in protecting organs in the body.

D) The system described here is the Endocrine system. This system involves several internal glands (such as the thyroid gland and the adrenal glands) in the body.

NOTE: Identify which organ and/or tissue is present in the diagram and use that to select the appropriate option from the description of each of the options provided above.

hope it helps <3

Answer:

1. Molecular equation

BaCl2(aq) + 2AgNO3(aq) –> 2AgCl(s) + Ba(NO3)2 (aq)

2. Complete Ionic equation

Ba²⁺(aq) + 2Cl¯(aq) + 2Ag⁺(aq) + 2NO3¯ (aq) —> 2AgCl(s) + Ba²⁺(aq) + 2NO3¯(aq)

3. Net ionic equation

Cl¯(aq) + Ag⁺(aq) —> AgCl(s)

Explanation:

Answer:

The symbol for magnesium chloride is MgCl2 and silver nitrate is Ag(NO3)2 so the equation will be :

MgCl2 + Ag(NO3)2 → AgCl2 + Mg(NO3)2

Answer:

Mass = 0.287 g

Explanation:

Given data:

Number of moles of MgCl₂ = 0.001 mol

Mass of precipitate formed (AgCl) = ?

Solution:

Chemical equation:

MgCl₂(aq) + 2AgNO₃(aq)    →       Mg(NO₃)₂(aq) + 2AgCl (s)

now we will compare the moles of MgCl₂ and AgCl.

            MgCl₂           :            AgCl

                1                :             2

           0.001             :       2/1×0.001 = 0.002

Mass of AgCl:

Mass = number of moles × molar mass

Mass = 0.002 mol × 143.4 g/mol

Mass = 0.287 g

Answer:

Mass of MgF₂ formed = 40.5 g

Explanation:

Given data:

Mass of NaF = 55 g

Mass of MgF₂ formed =  ?

Solution:

Chemical equation:

2NaF  +  Mg      →     MgF₂ + 2Na

Number of moles of NaF:

Number of moles = mass/molar mass

Number of moles = 55 g / 41.98 g/mol

Number of moles = 1.3 mol

now we will compare the moles of sodium fluoride with magnesium fluoride.

                     NaF       :          MgF₂

                       2          :             1

                     1.3          :        1/2×1.3 =  0.65 mol

Mass of magnesium fluoride:

Mass = number of moles × molar mass

Mass = 0.65 mol × 62.3 g/mol

Mass = 40.5 g
