Answer:

The force then channels down through the walls to the floor. The force of the walls pushing down on the floor is exactly balanced by an equal force when the floor pushes up on the wall. ... The main, structural walls are called load-bearing walls and they're usually built from solid brick or stone.

Toluene, C7H8, is used in the manufacture of explosives such as TNT (trinitrotoluene). A 1.500 g sample of liquid toluene was pl

dusya [7]

Answer:

There were 63.67 kJ liberated

If 1 mol of toluene was burned, there would be liberated 3906 kJ / mole

Explanation:

Step 1: Data given

Mass of the toluene sample = 1.500 grams

The temperature of the calorimeter rose from 25.000 °C to 26.413 °C

Write the balanced chemical equation for the reaction in the calorimeter.

C7H8(l) + 9O2(g) ⇒ 7CO2(g) + 4H2O(l)

Step 2: Calculate Q of the calorimeter

Q = C * Δt

Q = 45.06 kJ/ °C * ( 26.413 - 25)

Q = 63.67 kJ

Step 3: Calculate moles of toluene

Moles toluene = mass toluene / molar mass toluene

Moles toluene = 1.500 grams /92.14 g/mol

Moles toluene = 0.0163 moles

Step 4: Calculate energy per mole

energy per mole = 63.67 kJ / 0.0163 moles = 3906 kJ / mole

MULTIPLE CHOICE QUESTION

schepotkina [342]

Answer:

(a) The slope of distance-time graph gives the speed of the objects.

As the slope of object (B) is the greatest among all, thus B has the largest speed and hence it is the fastest among all the objects.

(b) : As the curve of the objects do not intersect with each other even once, hence they cannot be at the same point on the road at the same time.

∴ 1 small line =

=0.57 km

Position of C at the instant B passes A is 8 km

(d) ; Position of B at the instant it passes C is 2nd small line above 4 km i.e. 4+2×0.57=5.14 km

∴ Distance traveled by B =5.14−0=5.14 kmV
