Moles of Lithium phosphate : 0.495

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

the answer I's the first one

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

Answer:

Fluorine is most likely to bond with lithium One lithium (Li) atom can combine with one fluorine (F) atom. Together, they make the formula LiF. Fluorine has seven electrons of it's own. Lithium gives up its one electron to make both atoms happy.

Answer:

or example, most samples of the elements hydrogen, oxygen, and nitrogen are composed of molecules that contain two atoms each (called diatomic molecules) and thus have the molecular formulas H2, O2, and N2, respectively. ... A molecule of sulfur is composed of eight sulfur atoms and is therefore written as S8.

% yield = 80.719

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

Answer:

28g/mol

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:

56g * (1mol / 28g) =

Explanation:

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.

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.

Answer:

atom

Explanation:

The smallest representative particle of an element is an atom.

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.

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

Solution

Gay Lussac's Law  

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

1) The given measurement have four significant figures 1234.

2)  All non-zero digits are consider significant figures like 1, 2, 3, 4, 5, 6, 7, 8, 9.

3) Zero between the non zero digits are consider significant like 104 consist of three significant figures.
