He realized he needs to have the upper body and lower body held in place and needed the buckle as far down beside the person's hip so it could hold the body properly

Explanation: ''I realized both the upper and lower body must be held securely in place with one strap across the chest and one across the hips,'' Mr. Bohlin once said. ''The belt also needed an immovable anchorage point for the buckle as far down beside the occupant's hip, so it could hold the body properly during a collision.

What volume of benzene (C6H6, d= 0.88 g/mL, molar mass = 78.11 g/mol) is required to produce 1.5 x 103 kJ of heat according to t

Anton [14]

Answer:

We need 42.4 mL of benzene to produce 1.5 *10³ kJ of heat

Explanation:

Step 1: Data given

Density of benzene = 0.88 g/mL

Molar mass of benzene = 78.11 g/mol

Heat produced = 1.5 * 10³ kJ

Step 2: The balanced equation

2 C6H6(l) + 15 O2(g) → 12 CO2(g) + 6 H2O(g) ΔH°rxn = -6278 kJ

Step 3: Calculate moles of benzen

1.5 * 10³ kJ * (2 mol C6H6 / 6278 kJ) = 0.478 mol C6H6

Step 4: Calculate mass of benzene

Mass benzene : moles benzene * molar mass benzene

Mass benzene= 0.478 * 78.11 g

Mass of benzene = 37.34 grams

Step 5: Calculate volume of benzene

Volume benzene = mass / density

Volume benzene = 37.34 grams / 0.88g/mL

Volume benzene = 42.4 mL

We need 42.4 mL of benzene to produce 1.5 *10³ kJ of heat

10. A rectangle box measures 6.00 in. in length, 7.00 in. in width, and 8.00 in. in height. What is the volume of the box in lit

erastova [34]

A rectangle box measures 6.00 in. in length, 7.00 in. in width, and 8.00 in. in height. The volume of the rectangular box is 5.506 L

Given,

1 inch = 2.54 cm

Length = 6.00 inches = 6.00 x 2.54 cm = 15.24 cm

Width = 7.00 inches = 7.00 x 2.54 cm = 17.78 cm

Height = 8.00 inches = 8.00 x 2.54 cm = 20.32 cm

Now,

Volume of rectangular box = Length x Width x Height

= 15.24 cm x 17.78 cm x 20.32 cm

= 5506.05 cm3

= 5506.05 mL (\small \because 1 cm3 = 1 mL)

= 5.506 L (\small \because 1000 mL = 1 L)

Hence, the volume of rectangular box is 5.506 L.
