Substance X has a specific heat capacity that is twice as large as Substance Y. If both samples ended up at the same change in temperature from the same amount of energy added, what is the relationship between the masses of the two samples? Explain.

Answers

Answer:

Substance X has a smaller mass

Explanation:

The relationship between the mass of the two samples is that the mass of X is smaller compared to the mass of Y.

 The specific heat capacity is given as:

         C  = [tex]\frac{H}{m x change in temperature}[/tex]

We can see that the higher the specific heat capacity the lesser the mass or simply put, the specific heat capacity of a body is inversely related to its mass.

If the amount of heat is constant i.e the same and the specific heat capacity of X is twice that of Y, then substance X has a smaller mass

The best solution to deforestation is to curb the felling of trees by enforcing a series of rules and laws to govern it. Deforestation in the current scenario may have reduced; however, it would be too early to assume. The money-churner nature of forest resources can be tempting enough for deforestation to continue.

Given that nitrogen forms
three bonds with hydrogen to
make NH3, how many hydrogen
atoms do you think will bond
with an atom of phosphorous?

Answers

Answer:

Three

Explanation:

Nitrogen and phosphorus are on the same group in the periodic table. Elements in the same group have similar chemical properties. This is because of the number of valence electrons that they share among each other.

 The valence electrons are the outermost shell electrons found within an atom.

Nitrogen and phosphorus can both be found on the fifth group on the periodic table.

Their oxidation state is:

either 5 or 8-5  = 3

Since phosphorus bonds with 3 hydrogen atoms, nitrogen will also do the same.

What is the empirical formula for C10h22

Answers


The empirical formula is
C5H11


Explanation:
We have decane, the alkane with a chemical formula of
C10H22
.
The empirical formula of a substance has the smallest ratio between the elements its composed of.
Here, we got the carbon to hydrogen ratio as
10:22
. So, we need to find the greatest common factor between the two numbers.

10=2*5

22=2*11

As you can see here, the greatest common factor between the two numbers is
2
, and so we divide both numbers by
2
.
10/2=5

22/2=11


And so, the new formula becomes

C5H11

DESCRIBE the five types of chemical reactions
(Synthesis, Decomposition, Single displacement, Double displacement, Combustion)

Answers

Syntesis- is a reaction that occur when two different atoms interact to form a different compound.
Decomposition- is a reaction in which compound breaks down into two or more simple substances.
Single displacement- is a reaction in which one element is substituted for another element in a compound
Double displacement- is a reaction in which the reactant ions exchange places to form new products.
Combustion- is a reaction in which the substance reacts with oxygen from the air, simply said combustion is when something’s burininv.

The study of chemicals is called chemistry.

When two elements react together to form a new compound is called a reaction.

When two-element join together to form a new compound is called synthesis.

[tex]C + O_2 --> Co_2[/tex]

The breakdown of a compound into two different elements is called decomposition.

[tex]H_20 ----> H_2 + O_2[/tex]

The substitute of one element in the compound is called single displacement.

[tex]Fe + H_2So_4---> FeSo_4+ H_2[/tex]

The substitute of two-element in the compound is called double displacement.

[tex]BaCl + H_2So_4 + ---> BaSo_4 + HCl[/tex]

The burning of the element in the presence of oxygen is called a combustion reaction.

[tex]C + O_2 ---> CO_2[/tex]

Hence, the answer is mentioned above.

A gas has a volume of 250.0 liters at 17.0 °C and 3.00 atm of pressure. what volume must the gas be increased for the gas to be at STP conditions?

Answers

Answer:

0.706 L (Liters)

Explanation:

P1V1 = P2 V2 3 atm 250.0 mL = 1 atm X

T1 T2 290 K 273 K

706 mL = X

The increased volume will be "706 L".

According to the question,

Pressure,

Initial, [tex]P_1 = 3 \ atm[/tex]Final, [tex]P_2 = 1 \ atm[/tex]

Temperature,

Initial, [tex]T_1 = 17^{\circ} C[/tex] or, [tex]290 \ K[/tex]Final, [tex]T_2 = 273 \ K[/tex]

Volume,

Initial, [tex]V_1 = 250 \ L[/tex]Final, [tex]V_2 = \ ?[/tex]

By using the Boyl's and Charl's combination law, we get

→ [tex]\frac{P_1 V_1}{T_1} = \frac{P_2 V_2}{T_2}[/tex]

or,

→ [tex]V_2 = \frac{P_1 V_1 T_2}{T_1 P_2}[/tex]

By putting the values, we get

→      [tex]= \frac{3\times 250\times 273}{290\times 1}[/tex]

→      [tex]= 706 \ L[/tex]

Thus the aforementioned answer is right.

Pseudoscience is a body of knowledge that is not based on the scientific method but on some unverifiable/unprovable claims.

Predictions about the future can only be valid if it is based on the scientific method, not just about the position of the planet. The scientific method involves observation, hypothesis formulation, testing of the hypothesis through repeatable experiments, and arriving at conclusion.

What is the temperature change that 725 g of aluminum will undergo when 2.35 x 104
J of thermal energy are added to it?

Answers

Answer:

36°C

Explanation:

Given parameters:

Mass of aluminum = 725g

Quantity of heat  = 2.35 x 10⁴J

Unknown:

Temperature change  = ?

Solution:

To solve this problem, we simply use the expression below:

  The quantity of energy is given as:

          Q  = m C Δt

Q is the quantity of energy

m is the mass

C is the specific heat capacity of aluminum  = 0.9J/g°C

Δt is the change in temperature

  The unknown is Δt;

             Δt  = [tex]\frac{Q}{mc}[/tex]    = [tex]\frac{2.35 x 10^{4} }{725 x 0.9}[/tex]    = 36°C

What colors are absorbed Best Buy the plant gizmo

Answers

Answer:

Yellow and Green

Explanation:

It is not blue the graph shows is isnt blue so the colors that absorbed the worse were green and yellow

Blue and red are the colors that plants can absorb the most. The pigments used for photosynthetic processes, such as chlorophyll in plant cells' chloroplasts, are what absorb particular visible-spectrum light wavelengths.

The energy of specific light wavelengths is absorbed by special pigments in chloroplasts of plant cells, resulting in a chemical chain reaction that is known as the light-dependent process of photosynthesis. The best visible light wavelengths for photosynthesis are in the blue (425–450 nm) and red (600–700 nm) ranges.

Chlorophylls do not absorb light at green and yellow wavelengths, as shown by the extremely low level of light absorption between 500 and 600 nm.
