Answer:
Different uses of Metals
Metals are usually very strong, most durable and highly resistant to everyday wear and tear. As such, they have been used since ancient times for a lot of things. And even today with advances in technology and a lot of other things the uses of metals have broadened greatly. Metals even play a key role in the economy. Let’s look at some important and popular metals uses.
In the Construction Industry
In electronics
In medicine
Machinery, Refractory and Automobiles
Decorative products
Other Uses
In the Construction Industry
Metals are the main component in the construction industry. Metals like iron, steel amongst others are the main materials used in construction of buildings and even homes.
In Electronics
Another important application of metals are in electronics. As metals are good conductors of electricity, they are used to making wires and parts for equipments and gadgets that function on electrical current. Popular examples include, TV, mobiles, fridge, iron, computers etc.
In medicine
If you are wondering how, well from a biological perspective metals are found as micro-elements in our bodies. Besides, the presence of metal elements is crucial for several functions like transmission of nerve impulses, oxygen flow, reaction between enzymes etc. Some medicines are therefore liaised with metal compounds to treat certain deficiencies or sickness. Metals like, iron, calcium, magnesium, potassium titanium, and aluminum are used commonly in medicine in the form of antacids.
Apart from this, most of the equipments and tools used are made from metals.
Machinery, Refractory and Automobiles
This is one of the most common use of metals. They are used extensively in manufacturing machines for industries, agriculture or farming and automobiles which include road vehicles, railways, airplanes, rockets etc. Here, the commonly used metals are iron, aluminum and steel.
Besides these, most of the utensils that is used in the kitchen are made from metals like steel, aluminum, and copper. Due to a high temperature withstanding nature metals are preferred the most.
Decorative products
Metals such as platinum, gold, and silver come under the category of precious metals and have high economical value. These metals are widely used in making jewellery sets or for some decorative piece.
Other Uses of Metals
Some other uses and applications of metals are, they play an important role in security as the metals are used in making locks, strong safe, doors etc. Apart from this, furnitures are made from metal these days. Metals also find their uses in the military where they are used to manufacturing weapons and ammunitions. Some metals are used in galvanizing to protect from rusting.
These are some popular uses of metal. To know more about metals, different types, properties of metals and more you can keep visiting BYJU’S or you can also download our app for interesting content and learning experience
The offsprings' traits depend on which parent the offspring inherited more copies of genes from. True or False?
Answer:
false
Explanation:
i did the test :)
The offsprings' traits depend on which parent the offspring inherited more copies of genes from. This statement is false.
What is gene ?The biological and functional component of heredity was conveyed from parent to child. Genes are bits of DNA, and the majority of genes include instructions for producing a particular protein.
However, it wasn't until Wilhelm Johannsen proposed calling the Mendelian factors of heredity genes that the name began to catch on. The suggested term was derived from the Greek word "genos," which means "birth." The term gave rise to others like genome.
Through their genes, parents transmit features or qualities to their offspring, such as eye color and blood type. There are several illnesses and medical disorders that can be genetically handed down. Sometimes a trait might take on many different forms.
Thus, The offsprings' traits depend on which parent the offspring inherited more copies of genes from. This statement is false.

Which type of prevailing wind would carry more water vapor (humidity)? (Choose one)
a. A global wind moving over the ocean
b. A global wind moving over land
Answer:
a global wind moving over the ocean
Explanation:
because it's picking up moisture from the ocean and kind of carrying the water with the wind and water obviously is part of the evaporation so it would kind of turn into water vapor which will have more humidity along with the heat because how the heat warms the water kind of like the sweat from a sweat glands if that makes sense I don't know if that makes sense to you but it makes sense to me lol
What has to be equal during chemical equilibrium?
Select one:
a.The rate of forming products and the rate of reaction
b.The rate of the forward reaction and the rate of the reverse reaction
c.The rate of forming reactants and the rate of forming products
d.The rate of the forward reaction and the rate of forming reactants
Answer:
answer is B
Explanation:
please tell me if im incorrect, i'll fix it asap.
The rate of the forward reaction and the rate of the reverse reaction has to be equal during chemical equilibrium. Therefore, the correct option is option B.
When the forward and reverse reactions in a chemical reaction happen at the same rate, there is no net change over time in the concentrations of reactants and products. This is known as chemical equilibrium. The concentrations of the reactants and products are constant in this state, but the reaction is still ongoing for each species. The equilibrium constant (K), also referred to as the ratio of reactant to product concentrations, is constant at equilibrium. The temperature and the stoichiometry of the balanced chemical equation affect K's value.

aAl +bFe2O3 ==> CAl2O3 + dFe?
Answer:
2Al + 1Fe2O3 ---> 1Al2O3 + 2Fe
Explanation:
The values of a, b, c and d required to balance the chemical equation are:
a = 2b = 1c = 1d = 2What is a chemical equation?Chemical equations are representations of chemical reactions using symbols and formula of the reactants and products.
The reactants are located on the left side while the products are located on the right side.
Reactants —> Products
The balancing of chemical equations follows the law of conservation of matter which states that matter can neither be created nor destroyed during a chemical reaction but can be transferred from one form to another.
How to balance the equationaAl + bFe₂O₃ —> cAl₂O₃ + dFe
Al + Fe₂O₃ —> Al₂O₃ + Fe
There are 2 atoms of Al on the right side and 1 on the left. It can be balanced by writing 2 before Al as shown below
2Al + Fe₂O₃ —> Al₂O₃ + Fe
There are 2 atoms of Fe on the left side and 1 on the right. It can be balanced by writing 2 before Fe as shown below
2Al + Fe₂O₃ —> Al₂O₃ + 2Fe
Now, the equation is balanced.

Why a hot cup if water has more thermal energy than a cold cup of water?
Answer:
The hotter the substance, the more its molecules vibrate, and therefore the higher thermal energy
:)
Answer: Hot water has more thermal energy because the particles are farther apart thus they are moving faster. As particles move faster their thermal energy increases.

If 100.0g of nitrogen gas (N2) is reacted with 100.0g of hydrogen gas (H2) what is the limiting and excess reactants?
Hint: convert grams to moles for each reactant and then convert to moles of NH3. You need your balanced equation from answer 1 to determine the mole relationship between each reactant and the product NH3. Use the periodic table to determine the molar mass of all chemical formulas. Fill in the “?” Blanks below to show your work.
Please please please fill in the blanks...
Molar mass of H2= ____ g/mol
100.0g H2 • 1 mol H2/? g H2 • ? Mol NH3/ ? Mol H2 = ? Mol NH3
Molar mass of N2= ? g/mol
100.0g N2 • 1 mol N2/ ? g N2 • ? Mol NH3/ ? Mole N2 = ? Mol NH3
