what volume of 1.75 m hcl in liters is needed to react completely (with nothing left over) with 0.750 l of 0.100 m na2co3 ?
Evgesh-ka [11]

The balance chemical equation is :

2HCL + Na2CO3 -----> 2NaCl + H2O + CO2

According to Question,

Given,

Molarity of HCL = 1.75 m

Sodium Carbonate (Na2CO3) = 0.100 m

For finding out the molarity,

c = n solute / Vsolution  => n = c.Vsolution

nCO^2-3 = 0.100 mol L^-1 . 0.750 L = 0.0750 moles of CO^2-3

0.0750 moles of CO^2-3 . 2 moles H3O^+ / 1 mole CO^2-3

= 0.150 moles of  H3O^+

As we have already know the molarity of HCL , we easily calculate what volumes by many moles.

c = nsolute / Vsolution => Vsolution = nsolute / c

VH3O^+ = 0.150 moles / 1.75 mol L^-1 =  0.0857 L

What would be the wavelength of light that has a frequency of 3 X<br> 10-4 Hz in a vacuum?
ziro4ka [17]

Answer:

\lambda=10^{12}\ m

Explanation:

Given that,

The frequency of the light, f=3\times 10^{-4}\ Hz

We need to find the wavelength of the light.

The relation between frequency, wavelength and the speed of light is given by :

c=f\lambda\\\\\lambda=\dfrac{c}{f}\\\\\lambda=\dfrac{3\times 10^8}{3\times 10^{-4}}\\\\\lambda=10^{12}\ m

So, the wavelength of the light is 10^{12}\ m.

Calculate the density of sulfuric acid if 35.4 ml of the acid has a mass of 65.14 grams. (Please show how you got this answer)
vesna_86 [32]

Answer:

d = 1.85 g/cm³

Explanation:

Given data:

Volume of sulfuric acid = 35.4 mL

Mass of sulfuric acid = 65.14 g

Density of sulfuric acid = ?

Solution:

1 ml = 1cm³

Formula:

d = m/v

d = 65.14 g / 35.2 cm³

d = 1.85 g/cm³
