It is a combustion reaction because when methane burns with oxyzen it produces carbon dioxide,water and heat and light.
Answer:
The isotope notation for an ion of silver-109 with a charge of positive 1 is 
.
Explanation:
The elements with same atomic number with different mass numbers are called isotopes.
The isotopes of silver is as follows.
From the above two isotopes have same atomic number and different mass number.
From the given,the isotope notation for an ion of silver-109 with a charge of positive 1
It can be represented is as follows.
General representation of isotope is as in attachment.
<span>Earth has a much greater mass than Pluto does, and therefore has stronger gravity.</span>
Taking into account the Newton's second law, the correct answer is option A. F = 9.68 N right
In first place, acceleration in a body occurs when a force acts on a body.
Newton's second law states that a force will change the speed of an object because the speed and/or direction will change. These changes in velocity are called acceleration.
So, Newton's second law defines the relationship between force and acceleration mathematically. This law says that the acceleration of an object is directly proportional to the sum of all the forces acting on it and inversely proportional to the mass of the object
Mathematically, Newton's second law is expressed as:
F= m×a
where:
- F = Force [N]
- m = Mass [kg]
- a = Acceleration [m/s²]
In this case, you know:
- F= ?
- m= 2.2 kg
- a= 4.4 m/s²
Replacing in Newton's second law:
F= 2.2 kg× 4.4 m/s²
Solving:
<u><em>F= 9.68 N</em></u>
Finally, As the bowl of fruit accelerates to the right, the correct answer is option A. F = 9.68 N right

First of all write a balanced equation.
4Na + O2 -> 2Na2O
You are starting with a mass of sodium. You need to use sodium’s molar mass. Take this quantity times mole to mole ratio between sodium and sodium oxide to get moles of sodium oxide produced.
