Answer:

98 g/mol

Explanation:

La masa molar de un compuesto es la cantidad de materia (medida como masa) que hay en 1 mol de dicho compuesto. Por lo tanto, puede calcularse como sigue:

masa molar = masa/número moles

Tenemos los siguientes datos del compuesto Y:

masa Y = 196 g

número de moles de Y = 2 mol

Entonces, podemos calcular la masa molar de Y de la siguiente manera:

masa molar Y = (masa Y)/(número de moles de Y) = 196 g/2 mol = 98 g/mol

Answer: Positive tropism, negative tropism

Explanation:

Stimulus can be define as external and internal agent which generate a response in an organism. If the growth and action is towards the stimulus it is called as positive tropism. If the growth and action is away from the stimulus it is called as negative tropism. Example, the growth of the stem towards the sunlight is called positive tropism whereas the growth of the root away from the sunlight is called negative tropism. Here, sunlight is the stimulus.

Answer:

CH2

Explanation:

The empirical formula is the simplest formula of a chemical compound. It shows the ratio in which constituent atoms are combined in the compound.

To obtain the empirical formula, we divide the given mass of each element by the relative atomic mass of that element.

C- 36.0 g/12.0 g         H- 6.0g/1.0g

C- 3                             H-6

Divide through by the lowest ratio;

C-3/3                              H- 6/3

C-1                                  H-2

Hence the empirical formula of the compound is

CH2

Answer:

26.56g

Explanation:

The half life of an isotope decay is the time transcurred when the initial amount of the isotope decays to the half of its amount.

For the problem, when 1 half life transcur, the sample has a mass of:

425g / 2 = 212.5g

When 2 half lives transcur:

212.5g / 2 = 106.25g

3 half lives:

106.25/2 = 53.13g

And the amount that is found after 4 half lives is:

53.13/2 =

Answer:

50.63 cm³

Explanation:

Using Charles law equation as follows:

V1/T1 = V2/T2

Where;

V1 = initial volume (cm³)

V2 = final volume (cm³)

T1 = initial temperature (K)

T2 = final temperature (K)

According to the question, V1 = 45.0 cm³, V2 = ?, T1 = 280 K, T2 = 315 K

Using; V1/T1 = V2/T2

45/280 = V2/315

Cross multiply

45 × 315 = 280 × V2

14175 = 280V2

V2 = 14175 ÷ 280

V2 = 50.625

V2 = 50.63 cm³

Answer:

3 moles of CaO

Explanation:

The chemical balanced equation is;

2Ca + O₂ → 2CaO

The ratio of calcium(Ca) to Calcium Oxide(Cao) in this equation is 2:2.

Now, when 3 moles of calcium react with oxygen, Cao produced will be;

3 moles of O₂ × 2 moles of CaO/2 moles of Cao = 3 moles of CaO

Answer:

No.

Explanation:

Photosynthesis is the light dependent process which must occur for the plant to live. This process also requires water and carbon dioxide. If photosynthesis does not occur, the plant will die.

If plants do not receive enough water from the water cycle, photosynthesis can be affected, and in severe cases, it may not take place at all.

Photosynthesis requires water as one of its essential inputs, as it is used in the process of creating glucose and oxygen from carbon dioxide and light energy. Therefore, if plants do not receive enough water from the water cycle, photosynthesis can be impacted, and in severe cases, it may not take place at all.

Water is not only a raw material in photosynthesis, but it is also necessary for the regulation of plant cells' internal pressure, which is essential for maintaining their shape and structure. Without enough water, the cells' internal pressure decreases, causing them to shrink and lose their rigidity. This process is known as wilting.

Hence, water is essential for plant growth and photosynthesis, and if plants do not receive enough water from the water cycle, it can lead to wilting, stunted growth, and a reduction in photosynthesis.

Answer:

Barium

Explanation:

The specific heat of a material is a property defined as the amount of energy required to increase the temperature of 1g of this material in 1°C = 1K

Explanation:

In its stable molecular form, oxygen exists as two atoms and is written O2. to distinguish it from an atom of oxygen O, or ozone, a molecule of three oxygen atoms, O3. Even though each of these is all oxygen, combining atoms of the same element may give very different properties to the molecule.

The daughter element is produced from the beta decay of ¹⁴⁵₅₆Ba is ¹⁴⁵₅₇La.

A beta particle is emitted from the nucleus of an atom during radioactive decay. The electron, however, occupies regions outside the nucleus of an atom.

Beta particle has no mass and minus charge on itself.

Radioactive decay equation for the Barium is shown as follow:

¹⁴⁵₅₆Ba → ¹⁴⁵₅₇La + °₋₁β

The daughter element which is produced from the from reaction is Lanthanum.

Hence, ¹⁴⁵₅₇La is the daughter element.

Answer:

The pressure of the gas at 323 degrees Celsius is 2 atm.

Explanation:

Gay-Lussac's law indicates that, as long as the volume of the container containing the gas is constant, as the temperature increases, the gas molecules move faster. Then the number of collisions with the walls increases, that is, the pressure increases. That is, the pressure of the gas is directly proportional to its temperature.

In short, when there is a constant volume, as the temperature increases, the pressure of the gas increases. And when the temperature is decreased, the pressure of the gas decreases.

Gay-Lussac's law can be expressed mathematically as follows:

[tex]\frac{P}{T} =k[/tex]

Where P = pressure, T = temperature, K = Constant

Having two different states, an initial state 1 and a final state 2, it is satisfied:

[tex]\frac{P1}{T1} =\frac{P2}{T2}[/tex]

In this case:

Replacing:

[tex]\frac{1 atm}{298 K} =\frac{P2}{596 K}[/tex]

Solving:

[tex]P2=\frac{1 atm}{298 K}*596 K[/tex]

P2= 2 atm

The pressure of the gas at 323 degrees Celsius is 2 atm.
