Calculate the maximum mass of iron that can be obtained from 240 tonnes of iron oxide
Answer:
167.86 tonnes
Explanation:.
I am assuming the iron oxide is Fe2O3 (Haematite) which is the most common form of iron oxide.
From the atomic masses:
Maximum Mass of iron = 240 * 2*55.845 / (2*55.845 + 3*15.999))
= 240 * 111.69 / (159.687)
= 167.86 tonnes

How many grams of 40% (w/w) NaOH solution should be added to 600 g of water to obtain
10% (w/w) NaOH solution.
Explanation:
One mole of NaOH weighs 40gm.
Now 2M solution of NaOH indicates 2 moles of NaOH in 1 litre of water.
So the above question can now be simplified as …if one litre of water contains 80gm(2 moles) of NaOH, then how many grams of NaOH would 250ml solution of the same contain?
Using unitary method,
1000ml corresponds to 80gm NaOH…
1000/4 ml(250ml) corresponds to 80/4 gm NaOH…
Therefore, for 250ml of 2M NaOH, 20 gm of NaOH needs to be added to water.
- Convert (a) 0.5722 L to mL (b) 540.0 m to cm?
Answer:
(a)572.2ml
(b)54000cm
Explanation:
(a) 1 l = 1000 ml
0.5722 l =?
=572.2 ml
(b) 1m = 100cm
540m=?
=54000cm
The various units like liter, meter, and kilogram are used to measure the objects and matter. 0.5722 L is equivalent to 572.2ml and 540.0 m is equivalent to 54000cm.
What are measuring units?Unit of measurements are magnitudes used to estimate the quantity of the matter and includes seven fundamental units, including meter, kilogram, seconds, candela, mole, kelvin, and ampere.
The fundamental units can be used to define other measurements that are called derived units, like volume, density, etc. The unit can be converted into various metric systems.
Unit conversions are done as:
1 L = 1000 mL0.5722 L = X mL
X = (0.5722 L × 1000 mL) ÷ 1 L
= 572.2 mL
1m = 100 cm540 m = X cm
X = (540 m × 100 cm) ÷ 1 m
= 54000cm
Therefore, 0.5722 L = 572.2 mL, and 540.0 m = 54000 cm.

Correct option : picture III and IV
The pictures lll and lV are depicting mixtures cuz they contain different kinds of atoms and molecules .
Picture III and IV shows the particles in the mixture. The correct option is D.
Thus, A mixture is a combination of two or more components that can be physically separated and are not chemically linked together.
Each component in a combination can exist in a variety of ratios while still maintaining its own characteristics. Mixtures fall into one of two categories: Homogenous and Heterogenous.
Homogeneous Mixtures: These mixtures, sometimes referred to as solutions, have a consistent composition throughout and make it challenging to identify the different components.
Thus, Picture III and IV shows the particles in the mixture. The correct option is D.

The unit that is equivalent to 75g is 0.075 kg, 750 dg, and 7.5 dag. The correct options are b, c, and d.
What are measuring units?Measuring units are the units used to denote the measurement quantities. There are seven basic measuring units. They are length, Time, Amount of substance, Electric current, Temperature, Luminous intensity, and Mass.
The current unit is given grams, which are used to measure the mass of any object.
1000 grams is equal to 1 kilogram and 1 dg = 0.1 g, and 1 dag = 10 g. So by this formula, each of the quantities can be calculated.
1 kg = 1000 g
So, 0.075 kg = (0.075 × 1000)g = 75 g
1 dg = 0.1 g
So, 750 dg = (750 × 0.1) g = 75 g
1 dag = 10 g
So, 7.5 dag = (7.5 × 10) g = 75 g
Thus, the correct options are b. 750 dg, c. 7.5 dag, and d. .075 Kg.

What is true of an element that is oxidized?
It increased in electronegativity.
It decreased in electronegativity.
It gained electrons.
It lost electrons.
Answer:
When an element is oxidized, it loses electrons
Answer:
The last option is the correct answer.
Explanation:
When an element is oxidized, it loses electrons. But when an element is reduced, it gains electrons. This is the basis of redox reactions.
However, an oxidizing agent oxidizes something else, and gets reduced, therefore gaining electrons. Meanwhile, a reducing agent reduces something else, and gets oxidized in the process, losing its own electrons.
