Answer;
Single replacement reaction
Explanation;
-There are five general types of reactions
. These includes; combination, decomposition, single replacement, double replacement, combustion.
-Single replacement reactions are reactions in which both reactants and products consist of an element and a compound
. For example in our case, for reactants, the element is Aluminium (Al) and the compound is NiBr2, and for products the element is Ni and the compound is AlBr3.
-Single replacement reactions involves a chemical change in which one element replaces a second element in a compound
. In this case Aluminium (Al) replaces nickel (Ni) in the compound NiBr2.
30 minuets for 20 mph because 10m/h /2
Equation:
NaOH + HCl ---> NaCl + H20
1mol 1mol
no. of moles of NaOH : 20× (25.0÷1000)=0.5 mol
NaCl : HCl
1mol : 1 mol
0.5mol:0.5mol
HCl molarity: 0.5 mol ÷ (10÷1000) =50 M
Answer:
The answer is
<h2>0.2 g/mL</h2>
Explanation:
The density of a substance can be found by using the formula
<h3>
</h3>
From the question
mass of object = 20 g
volume = 100 mL
Substitute the values into the above formula and solve
That's
We have the final answer as
<h3>0.2 g/mL</h3>
