Chemistry
1 answer:
shepuryov [24]3 years ago
8 0

Answer:

The mass of solid with density 14.2 g/cm3 and volume 350 cm3 is 4.97 Kg.

Explanation:

Formula for density is given below :

density = \frac{mass}{volume}

volume = 350 cm^{3}

density = 14.2 g/cm^{3}

Insert the values in the formula

14.2 = \frac{mass}{350}

on cross multiplication :

mass = density\times volume

mass = 14.2\times 350

mass = 4970 g

1 g = 0.001 Kg

mass =4970\times 0.001 Kg

mass = 4.97 Kg

Note : Check the units of volume and density carefully

2. Suppose that 21.37 mL of NaOH is needed to titrate 10.00 mL of 0.1450 M H2SO4 solution.
AysviL [449]

Answer:

0.1357 M

Explanation:

(a) The balanced reaction is shown below as:

2NaOH+H_2SO_4\rightarrow Na_2SO_4+2H_2O

(b) Moles of H_2SO_4 can be calculated as:

Molarity=\frac{Moles\ of\ solute}{Volume\ of\ the\ solution}

Or,

Moles =Molarity \times {Volume\ of\ the\ solution}

Given :

For H_2SO_4 :

Molarity = 0.1450 M

Volume = 10.00 mL

The conversion of mL to L is shown below:

1 mL = 10⁻³ L

Thus, volume = 10×10⁻³ L

Thus, moles of H_2SO_4 :

Moles=0.1450 \times {10\times 10^{-3}}\ moles

Moles of H_2SO_4  = 0.00145 moles

From the reaction,

1 mole of H_2SO_4 react with 2 moles of NaOH

0.00145 mole of H_2SO_4 react with 2*0.00145 mole of NaOH

Moles of NaOH = 0.0029 moles

Volume = 21.37 mL = 21.37×10⁻³ L

Molarity = Moles / Volume = 0.0029 /  21.37×10⁻³  M = 0.1357 M

As concentrated energy is used to do _____ , it becomes spread out.
nekit [7.7K]
As concentrated energy is used to do WORK, it becomes spread out.
The universe is made up of constant supply of energy. Energy is use to do work; the usefulness of energy is been degraded as it is been used to carry out work. For instance, the energy in petrol is used to run motor vehicles, the process result in the conversion of the chemical energy in the petrol to heat energy. The heat energy that is produced can not be easily gathered and used again, thus, the usefulness of that heat energy has been degraded.

The idea that light can act like packets led to what new field on science?
Elenna [48]

Light acting as 'packets' of exact amounts of energy (a particle-like quality) called quanta led to the development of quantum mechanics. Light also has wave qualities (wavelength, frequency, amplitude) which is referred to as particle-wave duality.
