Differences between Minerals and ore minerals

Answers

Answer 1

Answer:

Minerals are naturally occurring inorganic solids with a crystalline structure and a definite range of chemical formula. Ores are concentrations of minerals in rock that are high enough to be economically extracted for use. All ores are minerals, but all minerals are not necessarily ores.

Hope its helpful!

Answer 2

Minerals are inorganic solids that develop in nature and have a crystalline structure as well as a specific spectrum of chemical formulas. Ores are areas of mineral concentration in rock that may be economically mined for use. Lodestone is one of the iron ores. The mineral known as ore is where metal is easily and affordably mined. The composition of ore is known. Minerals are naturally occurring metals that are found in the crust of the planet. Ores are minerals that can be utilized to profitably extract metal.

How many total atoms are in 0.680 g of P₂O5?

Answers

Answer: 2.88×[tex]10^{24}[/tex]atoms [tex]P_{2}O_{5}[/tex]

Explanation: First, using stoichiometry, we must convert this from grams to moles, then from moles to atoms.

1. For the first step, we should also look at the periodic table to find the molar mass of the compound, then use that as the denominator.

[tex]0.680g P_{2} O_{5} *\frac{1molP_{2} O_{5} }{141.948gP_{2} O_{5} } =4.79mol P_{2} O_{5}[/tex]

2. Now that it is converted to moles, we must convert it to atoms by multiplying it by Avogadro's number.

[tex]4.79molP_{2} O_{5} *\frac{6.022X10^{23} }{1mol} =2.88*10^{24}[/tex]

With this information, we know that there are [tex]2.88X10^{24}[/tex] total atoms in 0.680 grams [tex]P_{2} O_{5}[/tex].

25g of gold with initially 27grade centigrade what is the final temperature uppon absorbing 2.3kj of heat

Answers

The final temperature of the mass of gold is  737 °C.

What is the specific heat capacity of gold?

The specific heat capacity of gold is 0.126 J/g/K

The final temperature, T2 of the gold is calculated as follows:

T2 = T + Q/mc

where;

T is initial temperature, m is mass, and c is specific heat capacity of gold.

T2 = 27 + 2.3 x 1000/(25 x 0.126)

T2 = 737 °C

Therefore, the mass and heat capacity of gold determines its final temperature.

How many kilograms of NH3 are needed to produce 120 of pf3 if the reaction has 78.1% yield.

Answers

99.25 grams = .09925 Kg of fluorine gas is needed.

What are moles?

A mole is defined as 6.02214076 × [tex]10^{23}[/tex]of some chemical unit, be it atoms, molecules, ions, or others. The mole is a convenient unit to use because of the great number of atoms, molecules, or others in any substance.

Balanced chemical reaction: P₄ (s) + 6F₂ (g) → 4PF₃ (g).

m(PF₃) = 120.0 g; mass of phosphorus trifluoride.

n(PF₃) = m(PF₃) ÷ M(PF₃).

n(PF₃) = 120 g ÷ 88 g/mol.

n(PF₃) = 1.36 mol.

From chemical reaction: n(PF₃) : n(F₂) = 4 : 6 (2 : 3).

n(F₂) = 1.36 mol · 3 / 2.

n(F₂) = 2.04 mol; amount of substance.

m(F₂) = n(F₂) · M(F₂).

m(F₂) = 2.04 mol · 38 g/mol.

m(F₂) = 77.52 g ÷ 0.781.

m(F₂) = 99.25 g.

Hence, 99.25 grams = .09925 Kg of fluorine gas is needed.

Suppose 0.258g of lead(II) acetate is dissolved in 250.mL of a 13.0 m M aqueous solution of ammonium sulfate.

Calculate the final molarity of acetate anion in the solution. You can assume the volume of the solution doesn't change when the lead(II) acetate is dissolved in it.

Round your answer to 3 significant digits.

Answers

Molarity is the estimation of the solute concentration in the solution. The final molar concentration of the acetate anion in the solution is 0.006 M.

What is Molarity?

Molarity is the ratio of the moles to the volume in liters.

Given,

Mass of lead (II) acetate = 0.258 gm

Volume of solution = 0.25 L

Moles are calculated as:

Moles = mass ÷ molar mass

= 0.258 g ÷ 325.29 g/mol

= 0.00079

Molarity is calculated as:

M = moles ÷ volume

= 0.00079 ÷ 0.25

= 0.0032

The molar concentration of the acetate ions: 2 × 0.0032 = 0.0064 M

Therefore, the molarity of the acetate anion in the solution is 0.006 M.

how do biotic components interact with abiotic components? explain with example.

Answers

Answer:

An ecosystem is defined by the interactions between the living and non-living things in any given area. Abiotic factors are the non-living components of an ecosystem. These include: air water, wind, soil, temperature, sunlight. One of the most critical interactions in an ecosystem between the biotic and abiotic environment is photosynthesis , the base chemical reaction that drives most life on earth. Plants and algae use sunlight, water and carbon dioxide to create the energy they need to grow and live via photosynthesis.

There are four main types of species interactions that occur between organisms in an ecosystem:

Predation , parasitism and herbivory – In these interactions, one organism benefits while the other is negatively affected.

* Competition – Both organisms are negatively affected in some way due to their interactions.

* Commensalism – One organism benefits while the other is neither harmed nor gains.

* Mutualism – Both organisms benefit from their interactions.

Plants with bird or butterfly pollinators are good examples of mutualistic interactions. Plants benefit by having their flowers pollinated so they can reproduce.

Answers

The osmotic pressure of the 0.250 L solution made with 1.60 g of glucose, in water at 25.00°C is 0.869atm.

How to calculate osmotic pressure?

The osmotic pressure of the solution can be calculated using the following expression:

PV = nRT

where;

P = pressureV = volumen = no of molesT = temperatureR = gas law constant

no of moles of glucose = 1.60g ÷ 180g/mol = 8.89 × 10-³mol

P × 0.250 = 0.00889 × 0.08206 × 298

0.25P = 0.217

P = 0.217/0.25

P = 0.869atm

In the scientific method, conducting an experiment involves designing and performing controlled experiments to test a hypothesis and the correct option is option B.

Scientists manipulate the independent variable while controlling other variables (dependent and controlled variables) to observe and measure the effect on the dependent variable.

By controlling variables, scientists can isolate the factors that influence the outcome, ensuring that any observed changes are a result of the manipulated variable and not other unrelated factors. This step allows for the collection of reliable data, which is essential for drawing meaningful conclusions based on the evidence gathered from the experiment.

There are 2 moles of O stones present in 88 grams of CO2. Why? Well, we can find the amount of moles present in 88 grams of CO2 by dividing the mass by the molar mass. The mass of CO2 comes out to be 88 grams. The molar mass of CO2 comes out to be 44 grams. Because 88 is the mass of CO2 and 44 is the molar mass of CO2, we can divide 88 by 44 to identify that there are 2.0 moles of O atoms present in 88 grams of CO2.

Answers

Neither attract much nor allows it be free.

How the molecules behave in such way?

Because fluorine has a higher electronegativity than carbon and hydrogen, CH3F possesses a non-zero dipole moment. As a result, fluorine draws a partial negative charge whereas other atoms (such as carbon or hydrogen) draw a partial positive charge, leading to a non-zero dipole moment in CH3F. Lewis' structure, CH3F, is made up of one carbon atom, three hydrogen atoms, and one fluorine atom. Carbon is the key atom in the CH3F lewis structure because it is the least electronegative. The CH3F lewis dot structure consists of 3 lone pairs and a total of 4 bound pairs.
