Describe how a homogeneous moisture differs from a heterogeneous mixture

Chemistry
1 answer:
Shalnov [3]3 years ago
3 0

Answer:

Explanation:

Mixture: is combination of one or more substances mix together.

• The properties of the mixture are not same and contains the properties of all those component present in it.

• it is a combination of one or more Pure substances and can be separated by simple physical methods.

• it have varying boiling and melting point

Homogeneous Mixture: are those which are not distinguish by naked eye but can be separated into its components by physical means.

The components of a homogeneous mixture are in the same phase oar in dissolved form so it look like one component.

Examples are:

• Salt water is mixture of water and NaCl and can be separated by physical mean.

• Air: mixture of gases

Heterogeneous mixture: are those which can be distinguishing by naked eye and can be separated into its components by physical means.

The component of heterogeneous mixture not fully mixed are different in color or different in phases or not soluble. So one can easily see the difference in the component of the mixture

Examples is

• mixture of salt and sand

• mixture of water and sand

What is the weight of a 90kg man standing on the moon, where gmoon = 1.64 m/s2?
Doss [256]

Answer:

The weigth of a 90kg man standing on the moon is <u><em>147.6 N (option C)</em></u>

Explanation:

Weight is called the action exerted by the force of gravity on the body.

The mass (amount of matter that a body contains) of an object will always be the same, regardless of where it is located. Instead, the weight of the object will vary according to the force of gravity acting on it.

The formula that allows you to calculate the weight of any body is:

W = m*g

where:

  • W = weight measured in N.
  • m = mass measured in kg.
  • g = acceleration of gravity measured in m/s². The acceleration of gravity g is the same for all objects that fall due to gravitational attraction, whatever their size or composition. For example, as an approximate value on Earth, g = 9.8 m/s².

In this case,  the mass m has a value of 90 kg and the gravity g has a value of 1.64 m/s², which is the value of the acceleration of gravity of the moon. Then:

W=90 kg* 1.64 m/s²

<u><em>W= 147.6 N</em></u>

Finally, <u><em>the weigth of a 90kg man standing on the moon is 147.6 N (option C)</em></u>

Determine the percentage composition of Ptl2
Hitman42 [59]

Answer:

Percent Composition

1. Find the molar mass of all the elements in the compound in grams per mole.

2. Find the molecular mass of the entire compound.

3. Divide the component's molar mass by the entire molecular mass.

4. You will now have a number between 0 and 1. Multiply it by 100% to get percent composition.

When coal or oil are burned, some part of it is completely combusted, forming co2; another part is partially combusted, forming
Arturiano [62]
These are main components of Industrial Smog. Smog is air pollutant. Main sources of Smog are 1) Coal, 2) Transportation Emission, 3) Natural Causes. Those areas are mainly effected which are located in Industrial Zones and those which has high traffic density. Cities like Delhi, Beijing, London, Maxico City, Log Angeles, Tehran e.t.c are reported to be highly effected by smog. Among these polutants, CO₂ is the main source of Global Warming, CO has adverse effects on human health as it has 200 times more potency to bind with Hemoglobin compared to Oxygen, SO₂ when present in air reacts with water producing acid rain e.t.c.

Draw a diagram using H+ signs and OH- symbols of a solution that is acidic. Hint: Use the
Dimas [21]

More positive ions shows acidic whereas more negative ions indicates basic solution.

<h3>Which charge show acidic solution?</h3>

That side which has more positive charges is considered as acidic solution while on the other hand, that region where negative charges are present in large number as compared to positive charges is considered as basic or alkaline solution.

So we can conclude that more positive ions shows acidic whereas more negative ions indicates basic solution.
