Answer:

In these lessons, students become familiar with the four key periods of growth and human development: infancy (birth to 2 years old), early childhood (3 to 8 years old), middle childhood (9 to 11 years old), and adolescence (12 to 18 years old).

Put this in scientific notation. 10 m to centimeters and 37.5 g/mL to kg/L
noname [10]

1m = 100cm

so 10m = 100*10 = 1000cm or in scientific notation 1.00x10^3 cm

1g = 1/1000kg

1mL = 1/1000L

so 1g/mL = (1/1000)/(1/1000)kg/L

=1kg/L

37.5g/mL = 37.5kg/L or 3.75*10^1 kg/L

A schoolbus accelerates to 65 mph and enters the freeway. It travels
Inessa [10]

Answer:

Distance cover by school bus = 149.5 miles

Explanation:

Given:

Velocity of school bus = 65 mph

Time taken by school bus = 2.3 hours

Find:

Distance cover by school bus

Computation:

Distance cover = Velocity x Time taken

Distance cover by school bus = Velocity of school bus x Time taken by school bus

Distance cover by school bus = 65 x 2.3

Distance cover by school bus = 149.5 miles

The standard molar heat of fusion of ice is 6020 j/mol. calculate q, w, and ∆e for melting 1.00 mol of ice at 0◦c and 1.00 atm p
zysi [14]

Answer :    q = 6020 J, w = -6020 J, Δe = 0

Solution : Given,

Molar heat of fusion of ice = 6020 J/mole

Number of moles = 1 mole

Pressure = 1 atm

Molar heat of fusion : It is defined as the amount of energy required to melt 1 mole of a substance at its melting point. There is no temperature change.

The relation between heat and molar heat of fusion is,

q=\Delta H_{fusion}(\frac{Mass}{\text{ Molar mass}})  (in terms of mass)

or, q=\Delta H_{fusion}\times Moles     (in terms of moles)

Now we have to calculate the value of q.

q=6020J/mole\times 1Mole=6020J

When temperature is constant then the system behaves isothermally and Δe is a temperature dependent variable.

So, the value of \Delta e=0

Now we have to calculate the value of w.

Formula used :    \Delta e=q+w

where, q is heat required, w is work done and \Delta e is internal energy.

Now put all the given values in above formula, we get

0=6020J+w

w = -6020 J

Therefore, q = 6020 J, w = -6020 J, Δe = 0
