Physical change of a substance include the phase change of the substance. Melting is an example of physical change where, a solid melts to form its liquid.

What is a physical change?

The change in state or phase of a substance is called physical change such as, melting, boiling, crystallization etc. Whereas, the change that involves bond making or bond breaking is called a chemical change.

Nuclear decay is an example of chemical change a heavy unstable atom breaks into two stable nuclei by emitting certain radiation. Forming or breaking of chemical bonds are chemical changes.

Melting of a substances is its change from solid to liquid state. At this temperature, the solid state and liquid state of a substance comes in equilibrium.

This process does not involve any bond making or breaking hence, it is a physical change. Therefore, D is correct.

Explanation:

An analogy can be defined as a cognitive process which typically involves comparing things having similar characteristics or features for the purpose of explanation or clarification. An observation can be defined as a process which typically involves carefully monitoring something for the purpose of understanding and clarity. An inference can be defined as a cognitive process which involves reaching a conclusion or forming an opinion based on sets of evidence or reasoning.

1. Mary discovered that the cell membrane of a bacteria acts like a fence because it keeps some things in and other things out: this is an analogy because there's a comparison between the cell of a bacteria and a fence.

2. Mary walked into her room where her little son was playing, found a broken window, and thought immediately that her son had broken it: this is an inference because she immediately thought her son broke it.

3. Mary noticed that her counter top was warm to the touch: this is an observation which was based on an evidence of touch.

4. Mary noticed that the side walk was wet and thought that it may have been that the sprinklers had been on recently: this is an inference because it was based on her thoughts.

5. Mary counted and recorded 20 heart beats in 10 seconds: this is an observation because she actually counted her heart beats.

Natural process in which certain gases in the atmosphere keep heat near earth and prevent it from radiating into to space

Answers

The answer is Greenhouse effect

Hope this help

The greenhouse effect is a process in which gases in the atmosphere keep heat near earth and prevent it from radiating into space.

What is the greenhouse effect?

Greenhouse effect can be described as the process by which radiations from the sun are absorbed by greenhouse gases and do not travel back into space. This prevents the surface of the earth from freezing.

The sun heats up the earth’s atmosphere during the day and the earth cools down at night by radiating heat back into the atmosphere. The heat is absorbed by the greenhouse gases and makes the surface of the earth warmer, which makes the survival of living beings on earth possible.

But because of the increased levels of greenhouse gases, the temperature of the earth has considerably increased. The major contributors to greenhouse gases are automobiles, deforestation,  factories, etc. which increases the amount of these gases in the atmosphere.

The greenhouse gases do not allow radiation or heat to escape from the earth and increasing the surface temperature of the earth and leading to global warming.

1. When electrical energy is used what type of energy is also produced and considered to be waste energy? Thermal energy Mechanical energy Nuclear energy Radiant energy​

Answers

Answer:

Energia solar: é proveniente de uma fonte inesgotável: o Sol. Os painéis solares possuem células fotoelétricas que transformam a energia proveniente dos raios solares em energia elétrica. Tem a vantagem de não produzir danos ao meio ambiente.

Energia nuclear: energia térmica transformada em energia elétrica, é produzida nas usinas nucleares por meio de processos físico-químicos.

Energia eólica (ar em movimento): ela já foi utilizada para produzir energia mecânica nos moinhos. Atualmente é usada com o auxílio de turbinas, para produzir energia elétrica. É atraente por não causar danos ambientais e ter custo de produção baixo em relação a outras fontes alternativas de energia.

A energia elétrica também pode se transformar em outros tipos de energia ao chegar às residências ou em indústrias. Exemplos:

Energia térmica: quando vamos passar roupas, a energia elétrica é transformada em energia térmica através do ferro de passar.

Energia sonora e energia luminosa: recebemos iluminação em casa pela transformação da energia elétrica que, ao passar por uma lâmpada, torna-se incandescente, e o televisor nos permite receber a energia sonora.

Energia mecânica: usada nas indústrias automobilísticas para trabalhos pesados.

What is the chemical formula for the limiting reactant in the reaction shown? Write the balanced chemical equation for the reaction, using lowest whole-number coefficients.

Answers

1. What is the chemical formula for the limiting reactant in the reaction shown?

Answer: NO

2. Write the balanced chemical equation for the reaction, using lowest whole-number coefficients.

Answer: 2NO + 2H2 —-> 2H2O + N2

Taking into account the definition of limiting reagent and balanced reaction, you get:

NO is the limiting reagent.The balanced reaction is 2 NO +  2 H₂ → 2 H₂O + 1 N₂What is the chemical formula for the limiting reactant in the reaction shown?

The limiting reagent is one that is consumed first in its entirety, determining the amount of product in the reaction. When the limiting reagent is finished, the chemical reaction will stop.

The reagent in excess will be the one that is not completely exhausted during the reaction, that is, they are those that are partially consumed, "excess" amount of that reagent. This is because the amount of product obtained from the reaction will always depend on the amount of limiting reagent in the reaction.

In this case, you can see that you have two reactants: NO and H₂. Having 4 moles of NO and 5 moles of H₂, you can see that no moles of NO are present in the products, but there is 1 mole of H₂.

This indicates that NO is the limiting reagent, since it is completely consumed, while there is 1 mole of H₂ in excess.

In summary, NO is the limiting reagent.

Write the balanced chemical equation for the reaction, using lowest whole-number coefficients.

Taking into account that the reagents are in stoichiometric proportions when the reagents are combined with each other without any of them,  you can observe that the chemical equation is:

4 NO +  4 H₂ → 4 H₂O + 2 N₂

Dividing by 2 to get the lowest whole-number coefficients, the balanced chemical reaction is:

2 NO +  2 H₂ → 2 H₂O + 1 N₂

The density of zinc is 7.13 g/mL. What would be the volume of a 300.0 g sample of this metal?

Answers

Answer:

The answer is 42.08 mL

Explanation:

The volume of a substance when given the density and mass can be found by using the formula

[tex]volume = \frac{mass}{density} \\[/tex]

From the question

mass of metal = 300 g

density = 7.13 g/mL

We have

[tex]volume = \frac{300}{7.13} \\ = 42.07573632...[/tex]

We have the final answer as

42.08 mL

How many joules are contained in a snack cake that is labeled "230 Calories"?
(Hint: 1 Calorie - 1,000 calories, 1 cal - 4.184 J)
O A 9.62 X 102 J
B
9.62 X 1053
C. 54.9 J
5.49 X 10 to the power of 4

Answers

Answer:

9.62 × 10² J

Explanation:

In this problem, we need to convert 230 calories to joules. For this, we must know the conversion from calories to joules.

1 Calorie = 4.184 Joules

To find Joules in 230 calories, multiply 4.184 by 23. So,

230 Calorie = (230 × 4.184) Joules

= 962.32 Joules

or

230 Calories = 9.62 × 10² J

So, the correct option is (A).

Answer:

Explanation:

According to the laws of reflection, the speed of light is slowed down by denser media, hence the statement is false.

What is reflection?

Reflection of light is defined as a property of light ray that when it strikes a smooth surface it bounces back .Objects can be seen due to this property of light.Reflection is produced by all types of waves namely sound waves, light waves, electromagnetic waves.

Reflection of light is governed by laws of reflection which are also called as Snell's laws. According to laws of reflection, angle of incidence and angle of reflection are equal.The incident ray , reflected ray and normal all lie on the same side of the plane.Light travels in a straight line before, after and during the process of reflection.There are 3 types of reflection which are diffuse reflection,specular reflection and glossy reflection.
