The Pythagorean theorem is a^2 + b^2 = c^2. You use it when solving for the sides of a triangle.

Best Answer: 2 LiCl = 2 Li + Cl2
mass Li = 56.8 mL x 0.534 g/mL=30.3 g
moles Li = 30.3 g / 6.941 g/mol=4.37
the ratio between Li and LiCl is 2 : 2 ( or 1 : 1)

moles LiCl required = 4.37
mass LiCl = 4.37 mol x 42.394 g/mol=185.3 g


Cu + 2 AgNO3 = Cu/NO3)2 + 2 Ag
the ratio between Cu and AgNO3 is 1 : 2
moles AgNO3 required = 4.2 x 2 = 8.4 : but we have only 6.3 moles of AgNO3 so AgNO3 is the limiting reactant
moles Cu reacted = 6.3 / 2 = 3.15
moles Cu in excess = 4.2 - 3.15 =1.05

N2 + 3 H2 = 2 NH3
moles N2 = 42.5 g / 28.0134 g/mol=1.52
the ratio between N2 and H2 is 1 : 3
moles H2 required = 1.52 x 3 =4.56
actual moles H2 = 10.1 g / 2.016 g/mol= 5.00 so H2 is in excess and N2 is the limiting reactant
moles NH3 = 1.52 x 2 = 3.04
mass NH3 = 3.04 x 17.0337 g/mol=51.8 g
moles H2 in excess = 5.00 - 4.56 =0.44
mass H2 in excess = 0.44 mol x 2.016 g/mol=0.887 g

What is the value of x in the equation 2(x – 3) + 9 = 3(x + 1) + x?
Lana71 [14]

Answer:

Given the equation: 2(x-3)+9=3(x+1)+x

Distributive property of multiplication states that when a number is multiplied by the sum of the two numbers, the first number can be distributed to both of those numbers and multiplied by each of them separately i.e,

a \cdot (b+c) = a\cdot b+a\cdot c

Now, using distributive property to LHS and RHS, we get

2x-6+9=3x+3+x

Combine like terms on RHS;

2x-6+9 = 4x+3

or

2x+3 = 4x+3

Subtract 3 from both sides of an equation;

2x+3-3 =4x+3-3

Simplify:

2x = 4x

or

4x-2x =0

2x = 0

⇒ x =0

Therefore, the value of x in the given equation

2(x-3)+9=3(x+1)+x is 0.

earnstyle [38]
For this case we have the following expression:
 (x-1) / (3) = k
 Substituting the value of k = 3 we have:
 (x-1) / (3) = 3
 From here, we must clear the value of x.
 We have then:
 x-1 = 3 * 3
 x-1 = 9
 x = 9 + 1
 x = 10
 Answer:
 
The value of x is given by:
 
x = 10
