El agua de una alberca requiere de 35.8 gramos de desinfectante (NaClO), por cada 1000 L de agua para mantenerse limpia. El día de hoy el cuidador de la alberca no fue a trabajar y dejó al velador encargado de la adición de desinfectante al agua, pero al velador se le olvidó la cantidad y le agregó 65 g.

Answers

Answer 1

Answer:

816L adicionales para mantener la concentración

Explanation:

Cuánta agua debe adicionar el cuidador para que se mantenga la concentración del desinfectante?

El desinfectante, NaClO, idealmente debe estar en una concentración de:

35.8g / 1000L = 0.0358g/L

Como el velador agregó 65g de desinfectante, la cantidad de agua necesaria es:

65g * (1L / 0.0358g) = 1816L de agua son necesarios

Asumiendo que el velador agregó 1000L, el cuidador debe agregar:

1816L - 1000L =

816L adicionales para mantener la concentración

Given:

Initial speed (u): 30 m/s

Final speed (v): 0 m/s (rest)

Time elapsed (t): 3.0 s

Asked:

Acceleration (a)

Solution:

We will use the following expression.

a = (v-u)/t = (0 m/s - 30 m/s)/3.0 s = -10 m/s²

Final Answer:

a = -10 m/s²

2.

Given:

Initial speed (u): 50 km/h

Final speed (v): 60 km/h

Time elapsed (t): 20 s

Asked:

(a) Acceleration (a)

(b) Distance traveled (s)

Solution:

(a) First, we will convert the time to hours.

20 s × 1 h/3600 s = 0.0056 h

Then, we will use the following expression.

a = (v-u)/t = (60 km/h - 50 km/h)/0.0056 h = 1.8 × 10³ km/h²

(b) We will use the following expression.

s = u × t + 1/2 × a × t²

s = 50 km/h × 0.0056 h + 1/2 × 1.8 × 10³ km/h² × (0.0056 h)² = 0.31 km

Final Answer:

a = 1.8 × 10³ km/h²

s = 0.31 km

The following questions refer to the below molecules: (A) CO2 (B) H2O (C) CH4 (D) C2H4 (E) PH3 The molecule that has trigonal pyramidal geometry

Answers

Answer:

The given molecules are:

(A) CO2 (B) H2O (C) CH4 (D) C2H4 (E) PH3

Which one has trigonal pyramidal geometry?

Explanation:

According to VSEPR (valence shell electron pair repulsion) theory, a molecule with a central atom having hybridization sp3 and with one lone pair of electrons has trigonal pyramidal geometry.

Among the given molecules,

CO2 has central atom carbon with sp hybridization without lone pairs.

So, it is a linear molecule.

H2O, the central atom is oxygen with sp3 hybridization and oxygen has two lone pairs. So, its geometry is V-shape or bent.

CH4 has central atom carbon with sp3 hybridization and no pairs.

So, its geometry is tetrahedral.

C2H4 ethene has carbon atoms as the central atoms with sp2 hybridization and carbon has no lone pairs.

So, its geometry is trigonal planar.

Answer:

PH3 has central atom P with sp3 hybridization.

P has one lone pair on it.

Hence, the geometry of PH3 is trigonal pyramidal.

Compare the following in the three states of matter
a) inter particle space
b)inter particle force of attraction
c)particle motion

Answers

Explanation:

Anything that occupies space and has mass is called matter.

(a) Inter particle space

Solids - Atoms of a solid substance are closely packed with each other due to which there is very less or no inter particle space.Liquids - Atoms of a liquid are little loosely packed due to which there is some inter particle space.Gases - Atoms of a gas are very loosely packed due to which there is large inter particle space.

(b) Inter particle force of attraction

Solids - Atoms of a solid are attached to each other by strong force of attraction.Liquids - Atoms of a liquid have slightly less force of attraction as compared to a solid substance.Gases - Atoms of a gas have Vander waal forces. Hence, there is no inter particle force of attraction between atoms of a gas.

(c) Particle motion

Solids - There is low or negligible particle motion between atoms of a solid.Liquids - There is high particle motion as compared to that present in a solid.Gases - There is very high particle motion as compared to solids and liquids.

Why do scientists use scientific notation? A. It provides an easier way to write the element names. B. It provides an easier way to write chemical formulas. C. It provides an easier way to write scientific words. D. It provides an easier way to write very large and very small numbers.

Answers

Answer:

D

Explanation:

Scientists will use a scientific notation because, it provides the easier way to write a very large and very small numbers. Option D is correct.

Scientists use scientific notation to express numbers that are extremely large or small. Scientific notation allows for a more concise representation of these numbers by expressing them as a product of a coefficient and a power of 10.

For very large numbers, scientific notation makes it easier to handle and compare values. It allows scientists to focus on the significant digits and the scale of the number without having to write out all the zeros. It also simplifies calculations and reduces the chance of errors when dealing with such large values.

Similarly, for very small numbers, scientific notation provides a convenient way to express values without writing out a large number of decimal places. It allows scientists to express the magnitude of the number in a concise manner and enables easier comparison and calculations with other values.

Scientific notation is widely used in scientific fields such as physics, chemistry, astronomy, and engineering, where dealing with numbers of varying magnitudes is common. It provides a standardized and efficient way to represent and work with very large and very small numbers.

Hence, D. is the correct option.

How many moles of oxygen gas are consumed in the production of 5.00 g of iron(III) oxide from metallic iron? 4Fe(s)+3O2(g)→2Fe2O3(g) _____ mole(s) O2

Answers

Answer:

0.0469 mol of 02.

Explanation:

The balanced equation of this reaction is given as follows:

4Fe(s) + 3O2(g) → 2Fe2O3(s)

According to this equation, 3 moles of oxygen gas (O2) is consumed to produce 2 moles of iron(III) oxide (Fe2O3).

Using the formula, mole = mass/molar mass to convert mass of Fe2O3 to mole

Molar mass of Fe2O3 = 56(2) + 16(3)

= 112 + 48

= 160g/mol

mole = 5.00 g ÷ 160g/mol

mole = 0.03125mol of Fe2O3

Since 3 moles of oxygen gas (O2) is consumed to produce 2 moles of iron(III) oxide (Fe2O3).

0.03125mol of Fe2O3 will be produced when (0.03125 × 3/2) mol of oxygen gas is consumed.

0.03125 × 3/2

0.03125 × 1.5

= 0.0469 mol of 02.

Why can you not create a Punnett square to determine the height of an individual?

Answers

Answer:

Punnett squares do not provide accurate predictions on the distribution of phenotypes in offspring. ... This makes it difficult to make predictions regarding Down's syndrome since it cannot predict the prevalence of the offspring's genotypes about a population.

Explanation:

Limitations of Punnett squares as models of inheritance include the lack of information about likely variation in small samples such as individual families and the lack of information about population prevalence of parental genotypes (so no predictions can be made about population prevalence of offspring genotypes.

PreviousNext

Answers

Answer:

the molecules strike the walls of the container more often.

Explanation:

The pressure of a gas refers to the force per unit area exerted on the walls of container by gas molecules.

Since the average kinetic energy of gas molecules increases as the temperature of the gas increases, the molecules of the gas tend to strike the walls of the container more often as the temperature of the gas increases.

Hence, the pressure of a gas increases due to an increase in temperature because the gas molecules strike the walls of the container more often.

What is temperature ?

The average kinetic energy of particular atoms and molecules in a system is measured by the temperature.

What is ideal gas Law?

Ideal gas law explain the relationship between pressure. temperature and volume.

Ideal gas law can be expressed as, PV=nRT.
