Answer:

In both cases, let the tire contact with the curb ease some of the pressure, apply the parking brake and then place the transmission into Park. If you have a manual transmission, place the transmission in first gear when parking facing downhill and reverse when parking facing uphill.

A sheet of aluminum foil has a total area of 1.000 m2 and a mass of 3.636 g. What is the thickness of the sheet in millimeters?

olga2289 [7]

Answer:

$t=1.34\times 10^{-3}\ mm$

Explanation:

Given that,

Area of sheet of Aluminium foil is 1 m²

Mass of the sheet = 3.636 g

The density of Aluminium, $d=2.699\ g/cm^3$

We need to find the thickness of the sheet in millimeters.

The density of an object is given in terms of its mass and volume as follows :

$d=\dfrac{m}{V}$

V = volume, V = A×t, t = thickness of the sheet

So,

$d=\dfrac{m}{A\times t}\\\\t=\dfrac{m}{Ad}\\\\t=\dfrac{3.636\ g}{10000\ cm^2\times 2.699\ g/cm^3}\\\\t=0.000134\ cm$

Since, 1 cm = 10 mm

So,

t = 0.00134 mm

$t=1.34\times 10^{-3}\ mm$

if it takes 54 mL of 0.1 NaOH to neutralize 125 mL of an HCL solution, what is the concentration of HCL?

alexira [117]

Answer:

0.0432 M

Explanation:

We are given;

Volume of NaOH as 54 mL

Molarity of NaOH as 0.1 M

Volume of HCl as 125 mL

We are required to determine the concentration of HCl

Step 1; We write a balanced equation for the reaction between NaOH and HCl

The balanced equation is given by;

NaOH(aq) + HCl(aq) → NaCl(aq) + H₂O(l)

Step 2: Determine the number of moles of NaOH

Moles = Volume × molarity

Therefore;

Moles of NaOH = 0.054 L × 0.1 M

= 0.0054 Moles

Step 3: We use the mole ratio to determine the moles of HCl

From the equation;

1 mole of NaOH reacts with 1 mole of HCl

Therefore;

Moles of NaOH = Moles of HCl

Thus; moles of HCl = 0.0054 moles

Step 4: Determine the concentration of HCl

We know that;

Molarity = Moles ÷ Volume

Therefore;

Molarity of HCl = 0.0054 moles ÷ 0.125 L

= 0.0432 M

Therefore, the concentration of HCl is 0.0432 M
