Answer:

6.32 × 10⁻³

3.2560008× 10⁷

5.630× 10⁰

9.5002× 10¹

Explanation:

Scientific notation is the way to express the large value in short form.

The number in scientific notation have two parts.

The digits (decimal point will place after first digit)

× 10 ( the power which put the decimal point where it should be)

For example:

0.00632

In scientific notation =  6.32 × 10⁻³

32,560,008

In scientific notation  = 3.2560008× 10⁷

5.630

In scientific notation  = 5.630× 10⁰

95.002

In scientific notation  = 9.5002× 10¹

A certain sample of a liquid has a mass of 42 grams and a volume of 35 centimeters3. What is the density of the liquid?
BabaBlast [244]

Answer:

            1.2 g.cm⁻³

Solution:

Data Given:

                             Mass  =  42 g

                             Volume  =  35 cm³

Formula Used:

                             Density  =  Mass ÷ Volume

Putting values,

                             Density  =  42 g ÷ 35 cm³

                             Density  =  1.2 g.cm⁻³

lys-0071 [83]

Answer:

Alkanes

Explanation:

The description of the first molecule corresponds to a cycloalkane. In the cycloalkanes for each carbon atom there are 2 hydrogen atoms (CnH2n = C5H10).

The second molecule corresponds to an open chain alkane, where for every carbon atom there is double plus 2 hydrogen atoms (CnH (2n + 2) = C5H12)

What is the energy needed to raise 2.004g of water from 89.0°C to 139.0°C?
gulaghasi [49]

Answer:

The answer to your question is E = 419.435 J

Explanation:

Data

Mass = m = 2.004 g

Temperature 1 = T1 = 89°C

Temperature 2 = T2 = 139°C

Specific heat  of water = Cp = 4.186 J/g°C

Energy = E = ?

Formula

E = mCp(T2 - T1)

Substitution

E = (2.004)(4.186)(139 - 89)

Simplification and result

E = 8.3887(50)

E = 419.435 J
