Answer:

Physical property

Explanation:

There are two types of properties that can occur in a reaction viz: physical nd chemical. Physical property are those ones have do not change the chemical identity of the substance involved as opposed to chemical properties in which the chemical composition of the substances are changed.

Physical properties include signs such as change of phase i.e. solid to gas, melting and boiling points, colour etc.

Answer:

A.

Explanation:

Warmer temperatures can also lead to a chain reaction of other changes around the world. That's because increasing air temperature also affects the oceans, weather patterns, snow and ice, and plants and animals. The warmer it gets, the more severe the impacts on people and the environment will be.

The reactants are A: Carbon Dioxide and water

Answer:

3 and 6 (weight change and nothing changes)

Explanation:

Hi there!

A chemical change is a change when matter changes into a new substance and has a new chemical property.

The signs that a chemical change is taking place are:

1. change in color

2. change in smell

3. change in energy (for example, there is a change in temperature (thermal energy))

4. a gas is formed (fizzing/bubbling/foaming are signs of this!)

5. formation of a solid (a precipitate)

A physical change is any change to the size, shape, or state of a substance. The substance still has the same chemical property.

these are your eight options:

1. tarnished is formed (a sign of a chemical change; a change in color)

2. gas is produced (a sign of a chemical change)

3. weight change (NOT a sign of a chemical change. Even though the weight changed, the substance still has the same chemical composition and therefore, there wasn't any change to its chemical identity)

4. Temperature change (a sign of a chemical change; a change in energy)

5. color change (a sign of a chemical change)

6. nothing changes (NOT a sign of a chemical change. If nothing happens, the substance is still the same as it was originally and there was no change to its chemical identity.)

7. forms a precipitate (a sign of a chemical change)

8. energy is released (a sign of a chemical change)

therefore the two options that are NOT a sign of a chemical change are 3 and 6 (weight change and nothing changes)

Hope this helps! :)

Answer:

An ionic bond is a chemical bond that results from electrostatic attraction between positive and negative ions.

Explanation:

It occurs between a metal and a non-metal, and the electronegativity will always be greater than 1.7 (which are both expedient ways of identifying this type of reaction). I hope this helps!

Answer:

The correct answer is - 1/4 0f 6 gram or 1.5 gram to be exact.

Explanation:

Given:

Half-life of sulfate-12 = 18 years

number of half-lives - 2

initial amount - 6 grams.

Solution:

The Half-life of an element or substance is the required time to decay the half amount of the initial amount of the element.

Remaining amount = initial amount * (1/2)^n

here n = number of half lives

then,

Remaining amount = 6* (1/2)^2

= 6/4

= 1.5 g.

Thus, the correct answer is = 1.5 g or 1/4 of 6 gram.

Option B. 4.25×10¯¹⁹ J

Explanation:

From the question given above, the following data were obtained:

Frequency (f) = 6.42×10¹⁴ Hz

Energy (E) =?

Energy and frequency are related by the following equation:

Energy (E) = Planck's constant (h) × frequency (f)

E = hf

With the above formula, we can obtain the energy of the photon as follow:

Frequency (f) = 6.42×10¹⁴ Hz

Planck's constant (h) = 6.63×10¯³⁴ Js

Energy (E) =?

E = hf

E = 6.63×10¯³⁴ × 6.42×10¹⁴

E = 4.25×10¯¹⁹ J

Thus, the energy of the photon is 4.25×10¯¹⁹ J

Answer:

B. 4.25 x 10-19J is correct via a p e x

Answer:

I personally think it would be all of the above

Answer:

See Explanation

Explanation:

1) Let us recall that;

Mass number = number of protons + number of neutrons

Where;

Number of protons = ?

Number of neutrons =20

Mass number =39

Number of protons = mass number - number of neutrons

Mass of protons =39 - 20= 19 protons

2) Atomic number = 13

Number of neutrons =14

Then the mass number =13 +14 =27

The symbol of the element is 27X13

The number of protons= the number of electrons =13

The atomic number is the same as the proton number =13

Explanation:

Zn (s) + 2HCl (ac) ---> ZnCl2 (ac) + H2 (g)

El zinc se oxida y el hidrógeno se reduce. HCl es el agente oxidante mientras que Zn es el agente reductor.

2Na (s) + H2SO4 (ac) ----> Na2SO4 (ac) + H2 (g)

El Na se oxida y el hidrógeno se reduce. El ácido sulfúrico es el agente oxidante, mientras que el sodio metálico es el agente reductor de tge.

Ca (OH) 2 (ac) + H2CO3 (ac) ------> CaCO3 (s) + 2H2O (l)

Esta no es una reacción redox ya que no hay cambios en el número de oxidación de izquierda a derecha.

C6H12O6+6O2=6Co2+6H2o

The balanced chemical equation for the reaction of glucose (C₆H₁₂O₆) with oxygen gas to produce carbon dioxide gas and water vapor is C₆H₁₂O₆  + 6O₂ → 6CO₂ + 6H₂O

The balanced chemical equation is the equation in which the number of atoms on the left hand side that is reactant side is equal to the number of atoms on the right hand side that is product side in an equation.

The balanced chemical equation is:

C₆H₁₂O₆  + 6O₂ → 6CO₂ + 6H₂O

Thus, from the above conclusion we can say that The balanced chemical equation for the reaction of glucose (C₆H₁₂O₆) with oxygen gas to produce carbon dioxide gas and water vapor is C₆H₁₂O₆  + 6O₂ → 6CO₂ + 6H₂O
