Malleability is the physical property of the metal by which it can alter its shape. It is due to relatively weaker bonds between the particles. Hence, Option (D) is correct.
What is malleability?The ability of a material to form thin sheets under pressure by hammering or rolling is called malleability. The hammers and machines are used as an external force to alter the shape and structure. Aluminum, copper, gold, iron, etc are malleable metals.
Malleability is the property of metals due to their ability to change their shape beyond their limit of compression. These substances can be rolled or even can be made as sheets and are used in making tools and machines.
Therefore, option D. malleability is due to weaker bonds between its matter particles.

an object with a mass of 300 kg is observed to accelerate at the rate os 4m/s² what is the total force required
Answer:
75 Newton
Explanation:
In order to find the force of the object, you must remember that the equation N = (mass x acceleration). Therefore meaning you would divide 300 kilograms, the mass, by 4 meters per second (squared), the acceleration.
Hydrogen sometimes is “blank” an electron and sometimes it has an “blank” electron.
Hydrogen sometimes is missing an electron and sometimes it has an extra electron.
Helium (He) and hydrogen (H) are unique elements. Hydrogen has the abilities and electrons of two groups, one and seven, and occasionally has more electrons than it does.
What are electrons?Electrons are defined as a subatomic particle with a negative charge that makes up the nucleus of an atom along with protons and neutrons. For scientists, it can be challenging to monitor them because of how quickly they spin. The tiniest particles in an atom, you can put 2000 of them into a proton, they are drawn to the positive charge of the protons.
Because it has no neutrons in its nucleus, hydrogen (particularly hydrogen -1) is unusual. There is only one proton in the nucleus of hydrogen. The only element without neutrons is this one. Although it has a single electron orbiting its nucleus as well, hydrogen typically contributes this electron to form a single, positively charged proton instead.
Thus, Helium (He) and hydrogen (H) are unique elements. Hydrogen has the abilities and electrons of two groups, one and seven, and occasionally has more electrons than it does.

How does the smell of food being cooked spread so fast ???
Answer:
When we cook food in the kitchen, that's the region of higher concentration of the smell. By diffusion, the smell spreads to the whole room and thereby whole house, so anyone standing at a distance, can smell it.
Answer:
smell of cooked food spread fast bc when something is heated up, the kinetic energy of the molecules/particles increases and some of them even mix with the air and moves around. the first answer is also correct (i just explained it more detaily)
so, this is the reason :)

Which statement describes why the viscosity of olive oil is higher than that of rubbing alcohol?
Answer:
D
Explanation:
Most of the fluids have some resistance to their movement due to viscosity. The gases also exhibit viscosity. The molecules that make up olive oil are larger as compared to alcohol. So olive oil has high viscosity. The correct option is D.
What is viscosity?The viscosity of a fluid can be defined as the measure of a fluid's resistance to flow. It can also be known as the measure of a fluid's thickness or its resistance to the objects passing through it.
A fluid with high viscosity resists motion because of its strong intermolecular forces which gives high internal friction. The fluids can flow easily if they have very little intermolecular force of attraction. The SI unit of viscosity is poiseiulle (PI).
Here the molecules which make up the olive oil are found to be shorter than those which make up alcohol. So the oilve oil molecules have more resistance to sliding past one another.
Thus the correct option is D.

How many molecules of NH3 will be produced if I use 10g of H2?
Answer:
20.05 ×10²³ molecules
Explanation:
Given data:
Mass of hydrogen = 10 g
Number of molecules of ammonia = ?
Solution:
Chemical equation:
3H₂ + N₂ → 2NH₃
Number of moles of hydrogen:
Number of moles = mass / molar mass
Number of moles = 10 g / 2 g/mol
Number of moles = 5 mol
now we will compare the moles of hydrogen and ammonia.
H₂ : NH₃
3 : 2
5 : 2/3×5 = 3.33 mol
Number of molecules of ammonia:
1 mole contain 6.022 ×10²³ molecules
3.33 mol × 6.022 ×10²³ molecules / 1 mol
20.05 ×10²³ molecules

How many seconds in 16 years? (Ignore leap years). show work
Answer:
There are 504,576,000 seconds in 16 years.
Explanation:
To calculate the number of seconds in 16 years, let's first use simpler units since we are going to be working with large numbers.
First, calculate the number of seconds in one day (24 hours). We can do this with the common knowledge that there are 60 seconds in a minute, and 60 minutes in an hour, multiply the seconds and minutes:
[tex]60*60=3600[/tex]
Therefore, there are 3600 seconds in an hour. Since we know that there are 24 hours in a day, we can multiply the seconds by hours:
[tex]3600*24=86400[/tex]
Therefore, there are 86,400 seconds in a day.
Knowing that there are 365 days in a year, we can multiply 86,400 seconds by 365 days to calculate the number of seconds in a year:
[tex]86400*365=31536000[/tex]
Therefore, there are 31,536,000 seconds in a year.
Since the question is asking the number of seconds in 16 years, we can simply multiply 31,536,000 seconds by 16 years:
[tex]31536000*16=504576000[/tex]
Therefore, there are 504,576,000 seconds in 16 years.
