Explanation:
Joule is the SI unit of
Unit of measurement of mass: Kilogram(Kg)
Unit of measurement of Power: Watt(W)
Unit of measurement of Gravity: m/s^2
Hope this helps ;) ❤❤❤
The same number of each atom are on both sides of the equation.
The Law of conservation of mass states that matter is neither destroyed nor created in a chemical reaction. Therefore, the mass of the reactants will be equal to the mass of the products in a chemical reaction. According to the law matter is neither created nor destroyed in a chemical reaction.
<span>C. It is in the row below and therefore more reactive </span>
Question 16:
We are given the following balanced equation: (Remember to always balance the equation)
We are also told that Mg(OH)2 is in excess, meaning HNO3 is the limiting reactant, we will use its moles to find the number of moles of Mg(NO3)2, then we can convert that to mass.
The ratio between HNO3 and Mg(NO3)2 is 2:1
Therefore the number of moles of Mg(NO3)2 = 8.00 mol x (1/2) = 4.00 mol
Now we can convert the number of moles of Mg(NO3)2 to mass: molar mass of Mg(NO3)2 = 148,3 g/mol
So the mol will cancel the mol, then you will be left with g.
Ketchup is not a smoothie. Unlike smoothies, ketchup is cooked.
