To solve this equation you can use a basic molarity formula and substitute the correct values.
The formula for molarity is M = mol/L.
Start by changing your mL to L. To do this, divide 25 by 1000.
This results in:
.025 L
You can now rearrange your molarity formula to isolate what you are solving for, which is moles.
This leaves your formula as:
ML = mol
Now, plug in your converted volume and given molarity into the formula.
This leaves you with:
(0.100)(0.025) = mol
Multiply to find your final value for moles.
This results in:
0.0025 mol of HNO3

Work done can be calculated from force and distance the object moves.
The equation relating work done, force and distance is,
Given the force acting on the object = 289 N
Distance the object moves = 29 m
Calculating the work done from force and distance:
Work = Force * Distance
= 289 N * 29 m
= 8381 J

I believe it is the mechanical organ.
The correct answer is C ) the number of atoms of each element is the same in both the reactants and products.
For example this equation the combustion of methane CH4:
CH4 + O2 → CO2 +H2O
this is not balanced equation:
as we have the no.of C atoms on the right side = the atoms on the left side = 1
but the no.of H atoms on the right side = 2
and no.of H atoms on the left side = 4
so to get the balanced equation we have to make no.of atoms equal on both sides:
So, we put 2H2O instead of H2O
CH4 + O2 → CO2 + 2H2O
now the no of O atoms on the right side = 4
and the no.of O atoms on the left side = 2
so, we put 2O2 instead of O2 to make no.of O atoms equal on both sides
So we finally get the balanced equation:
CH4 + 2O2 → CO2 + 2H2O
-have 1 C atom on both sides
-have 4 H atoms on both sides
-Have 4 O atoms on both sides
So the equation will be balanced when no.of atoms of each element are the same in both the reactants and products
