Answer:

Si.

Explicación:

Sí, la aplicación de medidas de seguridad depende de las características de su entorno porque el entorno nos brinda para elegir las medidas de seguridad. Existen diferentes instrumentos utilizados para la seguridad de diferentes entornos. Algunas medidas de seguridad se aplican en un entorno mientras que el otro se aplica a otro entorno. Por ejemplo, el vallado es una medida de seguridad que se puede aplicar en el terreno pero no en el agua o cualquier zona fangosa, por lo que podemos decir que las características físicas deciden qué medida de seguridad se debe instalar en el entorno.

Answer:

3.75 moles

Explanation:

The chemical equation is 2CH₃OH + 3O₂ -> 2CO₂ + 4H₂O

2 moles of CH₃OH are burned by 3 moles of O₂

For 2.5 moles of CH₃OH are burned by x moles of O₂

Let's solve for x :

2*x=2.5*3 => 2*x=7.5 => x=3.75 moles of O₂ are needed to burn 2.5 moles of CH₃OH

This is a Charles' Law problem: V1/T1 = V2/T2. As the temperature of a fixed mass of gas decreases at a constant pressure, the volume of the gas should also decrease proportionally. Here, we are given the new volume of the gas after cooling, and we want to determine to what temperature the gas was cooled.

To use Charles' Law, the temperature must be in Kelvin (x °C = x + 273.15 K). We want to solve Charles' Law for T2, which we can obtain by rearranging the equation into T2 = V2T1/V1. Given V1 = 130 L, T1 = 250 °C (523.15 K), and V2 = 85 L:

T2 = (85 L)(523.15 K)/(130 L) = 342 K or 68.9 °C. If sig figs are to be considered, since all the values in the question are given to two sig figs, the answer to two sig figs would be either 340 K or 69 °C.  

Gases show great uniformity in their behaviour irrespective of their nature. The concept Charles's law is used here to determine the new temperature of the gas. The new temperature of the gas is 341.96 K.

At constant pressure, the volume of a given mass of gas is directly proportional to the temperature on Kelvin scale. The absolute scale of temperature is introduced by the scientist Charles. The temperature at which gases supposed to have zero volume is called the absolute temperature.

Mathematically the Charles's law can be expressed as:

V = constant × T

V / T = constant

For two different gases, the equation is:

V₁ / T₁ = V₂ / T₂

T₂ = V₂T₁ / V₁

85 × 523 / 130 = 341.96 K

Thus the new temperature of the gas is 341.96 K.

The elements that will form covalent bonds are Silicon (Si) and nitrogen (N), option C.

A covalent bond is formed between two atoms by the mutual sharing of one or more pairs of electrons. The two atomic nuclei attract these electrons at the same time. When the difference in electro-negativities of two atoms is too small for electron transfer to form ions, a covalent bond forms.

Hydrogen (H₂) is a molecule with a single covalent bond as well as Halogens like Fluorine (F), Chlorine (Cl), Silicon (Si) and nitrogen (N).

Plates on Earth are moving quickly. Yet, friction causes them to travel more slowly. So, the correct options are B and C.

Tectonic plates are enormous fragments of the upper mantle and crust of the Earth. They are composed of both continental and oceanic crust. Earthquakes occur around mid-ocean ridges and the large faults which mark the edges of the plates.

The Earth's plates are shifting swiftly. Nevertheless, friction slows their movement. Gravity causes the floating plates to rise and fall. On occasion, the movement of tectonic plates results in earthquakes.

When compared to the Earth's mantle, the plates behave like solid, unyielding shells. The lithosphere is the name given to this thick outer layer.

Thus, the correct options are B and C.

Answer:

Acceleration

Explanation:

Acceleration doesn't change one moment to the next, and therefore, doesn't count as a force.

The answer option which is not a force is: C. Acceleration.

A force can be defined as a push or pull of an object or physical body, which typically results in a change of motion (acceleration), especially due to the interaction of the object with another.

In Science, the three (3) most common examples of a force include the following:

In conclusion, acceleration is not an example of a force but a change in the rate of velocity of an object with respect to time.

Answer:

A bladder is like a balloon, because it holds urine, just like a balloon holds air. The urethra's function is to excrete urine from the human body.

Explanation:

A bladder and a balloon are similar, because it is the bladder which clasp urine, whereas a balloon clench air. The role of urethra is to eliminate urine from our human body.

The hollow organ which is in triangle shape and found in the lower abdomen just like a balloon is defined as the bladder. The urinary bladder is also known as a temporary reservoir of urine. Urine is reserved in the urinary bladder till it is removed out through the urethra.

As a result of the contraction of the wall of the urinary bladder, urine is eliminated from the body from time to time. The urine contains waste and extra fluid left over the body which has to be eliminated.

The bladder resembles the water balloon in that it holds urine in the similar way as the water balloon clench water. The water balloon pops when the amount of water exceeds than it can hold.

Thus the function of bladder and water balloon are found to be same.
