If 48.6 g of zinc is made, how many moles of lithium phosphate are also made? _______ moles

Answers

Moles of Lithium phosphate : 0.495

Further explanation

Given

6 Li + Zn₃(PO₄)₂ ------- > 2 Li₃PO₄ + 3 Zn

Required

Moles of Lithium phosphate

Solution

moles of Zinc(Ar=65,38 g/mol) :

= mass : Ar

= 48.6 : 65.38

= 0.743

From equation, mol ratio of Zn :  Li₃PO₄ = 3 : 2, so mol  Li₃PO₄ :

= 2/3 x mol Zn

= 2/3 x 0.743

= 0.495

Identify the apparatus on the table that is best suited for a chemist to measure the volume of a liquid.

Answers

Answer:

The third one from the left–the graduated cylinder.

Explanation:

The laboratory apparatus that gives an "accurate" or "precise" measurement of a liquid's volume is the graduated cylinder. All you have to do is to pour the liquid into the cylinder and read its measurement using the calibrated scale.

The graduated cylinder comes in different sizes, which means the scale divisions will depend on its size. When reading the measurement, it is important to take note to read at the bottom of the meniscus because it gives the most accurate volume.

What is the percent yield of this reaction if 22.o g of Mgl2 is produced by the reaction of 25.0 g of Mg with 25.0 g of l2?

Answers

% yield = 80.719

Further explanation

Given

22.0 g of Mgl₂

25.0 g of Mg

25.0 g of l₂

Required

The percent yield

Solution

Reaction

Mg + I₂⇒ MgI₂

mol Mg = 25 g : 24.305 g/mol = 1.029

mol I₂ = 25 g : 253.809 g/mol = 0.098

Limiting reactant = I₂

Excess reactant = Mg

mol MgI₂ based on I₂, so mol MgI₂ = 0.098

Mass MgI₂ (theoretical):

= mol x MW

= 0.098 x 278.114

= 27.255 g

% yield = (actual/theoretical) x 100%

% yield = (22 / 27.255) x 100%

% yield = 80.719

A certain amount of gas at 25°C and at a pressure of 0.800 atm is contained in a glass vessel. Suppose that the vessel can withstand a pressure of 2.00 atm. What is the maximum temperature in Kelvin that the gas can have without bursting the vessel?
a. 745 K
b. 62.5 K
c. 298 K
d. 760 K ​

Answers

The maximum temperature : a. 745 K

Further explanation

Given

Gas at 25°C(298 K) and at a pressure of 0.800 atm

Final pressure = 2 atm

Required

Final temperature

Solution

Gay Lussac's Law  

When the volume is not changed, the gas pressure in the vessel is proportional to its absolute temperature  

[tex]\tt \dfrac{P_1}{T_1}=\dfrac{P_2}{T_2}[/tex]

Input the value :

T₂=(P₂T₁)/P₁

T₂=(2 atm x 298 K)/0.8 atm

T₂ = 745 K = 472 °C

What is the molecular formula for a compound that is 40.0% C, 6.6% H, and 53.4% O and the molar mass is 120.0g/mol?

Answers

Answer:

molecular formula of the compound is C₄H₈O₄

Explanation:

First the empirical formula of the compound is determined:

Divide the percentage masses by the molar mass of each element to determine the mole ratio;

Carbon, C: 40/12 = 3.33

Hydrogen, H: 6.6/1 = 6.6

Oxygen, O: 53.4 / 16 = 3.3

dividing through with the smallest ratio to obtain the simplest whole number mole ratios

C = 3.3/3.3 = 1

H = 6.6/3.3 = 2

O = 3.3/3.3 = 1

Therefore, the empirical formula is CHO

molecular formula/mass = n (empirical formula/mass)

120 g/mol = n( 12 + 1 * 2 + 16)

30n = 120

n = 4 therefore, the molecular formula = 4(CH₂O)

molecular formula of the compound is C₄H₈O₄

2 moles of nitrogen are present

Explanation:

The molar mass is defined as the mass of a chemical when 1 mole of this substance is present and is used to convert mass of the substance to moles or vice versa. Is widely used in stoichiometry problems.

1 atom of nitrogen has a molar mass of 14g/mol. N₂(g) -The molecule that contains 2 atoms of nitrogen- has a molar mass of 28g. That is 28g/mol.

56g of N₂ are:

The ____________________ two objects are from each other, the _____________ the force of gravity between them. fill in spaces

Answers

Answer:

Farther, lesser

Explanation:

The farther the two objects are from each other, the lesser the force of gravity between them.

The force of gravitational attraction between two bodies is inversely proportional to the distance between them.

This premised on the Newton's law of universal gravitation which states that "the gravitational force of attraction between two bodies is directly proportional to the product of their masses and inversely proportional to the square of the distances between them".

So, the farther the distance, the lesser the gravitational attraction and vice versa.

Determine the final temperature of sample with a specific heat of 1.1 J/g°C and a mass of 385 g if it starts out at a temperature of 19.5°C and 885 J of energy are added to it.

Answers

Answer:

T2 =21.52°C

Explanation:

Given data:

Specific heat capacity of sample = 1.1 J/g.°C

Mass of sample = 385 g

Initial temperature = 19.5°C

Heat absorbed = 885 J

Solution:

Formula:

Q = m.c. ΔT

Q = amount of heat absorbed or released

m = mass of given substance

c = specific heat capacity of substance

ΔT = change in temperature

ΔT = Final temperature - initial temperature

885J = 385 g× 1.1 J/g.°C×(T2 - 19.5°C )

885 J = 423.5 J/°C× (T2 - 19.5°C )

885 J / 423.5 J/°C = (T2 - 19.5°C )

2.02°C = (T2 - 19.5°C )

T2 = 2.02°C + 19.5°C

T2 =21.52°C

What are atoms

Atoms are the fundamental building blocks of matter and the smallest unit of an element that retains the chemical properties of that element. Each atom consists of a nucleus at the center, composed of positively charged protons and neutral neutrons, surrounded by a cloud of negatively charged electrons.

Atoms combine to form molecules or ions through chemical reactions, but they themselves represent the basic structure and identity of an element. Each element has a unique number of protons in its nucleus, known as its atomic number, which determines its position on the periodic table and its distinct chemical properties.
