The equation below is for potassium oxide.
4K + O2 2K2O
What is the ratio of atoms of potassium to atoms of oxygen?

Answers

Answer:

The ratio of atoms of potassium to atoms of oxygen is  2:1

Explanation:

As the equation given is :

[tex]4K + O_2 -----> 2K_2O[/tex]

The product formed is 2 moles of potassium oxide .

Amount of potassium atom in the potassium oxide  is 2 atoms of potassium and amount of oxygen atom present here is 1 atom of oxygen .

But we have 2 moles of potassium oxide . So, the potassium and oxygen atoms will be multiplied by 2 .

Hence , we get 4 atoms of potassium and 2 atoms of oxygen .

Ratio of potassium to oxygen atoms is -   4:2

Therefore ,   2:1

What is the percentage by mass of solution formed by dissolving 36.0 grams of HCl in 98.0 grams of water?

73.1%
36.7%
26.9%
24.2%

Answers

Answer:

26.9%

Explanation:

I just took the test! :)

The percentage by mass of solution formed by dissolving 36.0 grams of HCl in 98.0 grams of water is 36.7%.

How to calculate percentage by mass?

The percentage by mass of a solution can be calculated by dividing the mass of the solute by the mass of the solvent, then, multiplied by 100.

percent by mass = mass of solute/mass of solvent × 100

According to this question, 36.0 grams of HCl is dissolved in 98.0 grams of water. The percentage by mass is calculated as follows:

percent by mass = 36g/98g × 100

percent by mass = 36.7%.

Therefore, the percentage by mass of solution formed by dissolving 36.0 grams of HCl in 98.0 grams of water is 36.7%.

A presión de 3atm, 7L de un gas a temperatura constante experimenta un cambio ocupando un volumen de 0,5L ¿Cuál será la presión que ejerce? ayuda

Answers

Answer:

La presión que ejerce es 42 atm.

Explanation:

La ley de Boyle relaciona la presión y el volumen y dice que  el volumen ocupado por una determinada masa gaseosa a temperatura constante, es inversamente proporcional a la presión.

La ley de Boyle se expresa matemáticamente como:

P*V=k

Ahora es posible suponer que tienes un cierto volumen de gas V1 que se encuentra a una presión P1 al comienzo del experimento. Si varias el volumen de gas hasta un nuevo valor V2, entonces la presión cambiará a P2, y se cumplirá:

P1*V1= P2*V2

En este caso:

P1= 3 atmV1= 7 LP2= ?V2= 0.5 L

Reemplazando:

3 atm* 7 L= P2* 0.5 L

Resolviendo:

[tex]P2=\frac{3 atm*7 L}{0.5 L}[/tex]

P2= 42 atm

La presión que ejerce es 42 atm.

Answer:10.5

Explanation:

3atm x 7L / 0,5L = 10.5

A 0.420 M Ca(OH)2 solution was prepared by dissolving 64.0 grams of Ca(OH)2 in enough water. What is the total volume of the solution formed? (4 points)
1.07 liters

2.05 liters
2.18 liters

Answers

Answer:

2.05 L is the correct answer.

Explanation:

w = 64 g

c = 0.420 M

m = 40 + (16+1)×2 = 74

[tex]c = \frac{w}{m \times v} \\ \implies \: v = \frac{w}{c \times m} \\ = \frac{64}{0.420 \times 74} \\ = 2.05 \: \: liters[/tex]

The volume of the solution is given below which can be calculated using the molarity formula.

d. 2.18 litres

Molarity:

It is defined as the ratio of number of moles of solute to the volume of the solution.

It is given by:

M= n/V

What information do we have?

M= 0.420M

mass = 64.0 grams

Molar Mass= 74g/mol

To find:

Volume of solution=?

Calculation for number of moles:

n= m/ M

n= 64/70

n= 0.91 moles

Molarity=  n/V

0.420 M= 0.91 moles /V

V= 0.91/ 0.420

V= 2.1768 litres

Thus, the volume of the solution is 2.18 litres.

Answers

Answer:

the pressure of a gas is directly proportional to its volume.

Explanation:

Robert Boyle was an Irish chemist and is famously referred to as the first modern chemist. He was born on the 25th of January, 1627 in Lismore, Ireland and died on the 31st, December 1691, London, United Kingdom.

Boyles states that when the temperature of an ideal gas is kept constant, the pressure of the gas is inversely proportional to the volume occupied by the gas.

Mathematically, Boyles law is given by;

[tex] PV = K[/tex]

[tex] P_{1}V_{1} = P_{2}V_{2} [/tex]

Where;

P1 is the original pressure.

P2 is the final pressure.

V1 is the original volume.

V2 is the final volume.

This ultimately implies that, ventilation which is typically governed by Boyle's Law, which states that at a constant temperature the pressure of a gas is directly proportional to its volume.

A container with a specific volume “V” changes to “2V.” What happens to the average distance between gas molecules? Assume that pressure and temperature of the gas remain constant.

Despite its appearance, air has a ‘thickness’ so when the sun is high in the sky the light travels through the air on a very much shorter path than when it is low on the horizon.

Imagine that air water and you are below the surface, the light from an overhead sun will be quite sharp and bright, but if lower in the sky it will have to travel through much more water to reach you, so will look less bright and sharp. It ma not seem the same, but the atmosphere is just like very thin water, and a low lying sun will be drastically reduced in strength, so all you will see is a sun with a shift to the red end of the spectrum as all the actinic part will be filtered away by that thicker atmosphere.

What is the molarity of a solution of 58.7 grams of MgCl2 in 359 ml of solution?

Answers

Answer:

1.72 M

Explanation:

Molarity is the molar concentration of a solution. It can be calculated using the formula a follows:

Molarity = number of moles (n? ÷ volume (V)

According to the information provided in this question, the solution has 58.7 grams of MgCl2 in 359 ml of solution.

Using mole = mass/molar mass

Molar mass of MgCl2 = 24 + 35.5(2)

= 24 + 71

= 95g/mol

mole = 58.7g ÷ 95g/mol

mole = 0.618mol

Volume of solution = 359ml = 359/1000 = 0.359L

Molarity = 0.618mol ÷ 0.359L

Molarity = 1.72 M
