Which boat experienced the greatest unbalanced force?

Answer:

Hydrogen has three naturally occurringisotopes: 1H (protium), 2H (deuterium), and 3H (tritium). Other highly unstable nuclei (4H to 7H) have been synthesized in the laboratory, but do not occur in nature. The most stable radioisotope ofhydrogen is tritium, with a half-life of 12.32 years.

Explanation:

Elastic potential energy is energy stored as a result of applying a force to deform an elastic object.

The overall order of the reactants in this rate law : 2

Given

Reaction

2O3 → 302

The rate law :

R= k[03]²

Required

The overall order

Solution

The overall order  : the sum of orders for each reactant

For A + B ---> C + D

r = k [A]ᵃ[B]ᵇ

The overall reaction order is m+n

So for the rate law of R= k[03]², the overall order = 2

Copper electrical wires are safer to use than wires made of most other conductive metals because they are resistant to heat. As you can see, copper is the preferred metal for electrical wires for several reasons. It has high electrical conductive; it's inexpensive; it's ductile; and it's thermal resistant.

You see, plants need energy to grow and grow and grow. They use energy from sunlight to make a simple sugar, glucose. Whenever the plant needs energy, it can chomp a little glucose off of the starch.

without energy it wont get energy/food so it will eventually die

Answer:

it's a covalent compound

Explanation:

Two non metals are bonded to together

Explanation:

Given:

20.5 torr

78.6 torr

225 torr

Change into atm

Computation:

We know that;

1 torr = 0.00131579 atm

So,

1. 20.5 torr

= 20.5 x 0.00131579 atm

= 0.02697

= 0.027 atm (Approx)

2. 78.6 torr

= 78.6 x 0.00131579 atm

= 0.103090

= 0.103 atm (Approx)

3. 225 torr

= 225 x 0.00131579 atm

= 0.2960

= 0.296 atm (Approx)

Answer:

The magnitude of the applied force is 3.15 N

Explanation:

Hooke's law states that for small deformations, the change in dimensions, 'x', of an object is directly proportional to the force, 'F', of the acting load acting that bring about the deformation

Mathematically, Hooke's Law can be expressed as follows;

F = k·x

Where;

F = The applied load

k = The force constant of the object

x = The amount of deformation of the object

The given parameters are;

The spring's force constant, k = 12.6 N/m

The amount of stretching in the spring, x = 0.25 m

Therefore, we have;

The force applied, F = k·x = 12.6 N/m × 0.25 m = 3.15 N.

Explanation:

Answer:

20 g of copper (II) oxide, CuO

Explanation:

The balanced equation for the reaction is given below:

CuO + 2HCl —> CuCl₂ + H₂O

From the balanced equation above,

1 mole of CuO reacted to produce 1 mole of CuCl₂.

Next, we shall determine the number of mole of CuO needed to produce 0.25 mole of CuCl₂. This can be obtained as follow:

From the balanced equation above,

1 mole of CuO reacted to produce 1 mole of CuCl₂.

Therefore, 0.25 mole of CuO will also react to produce 0.25 mole of CuCl₂.

Finally, we shall determine the mass of 0.25 mole of CuO. This can be obtained as follow:

Mole of CuO = 0.25 mole

Molar mass of CuO = 64 + 16

= 80 g/mol

Mass of CuO =?

Mole = mass /Molar mass

0.25 = mass of CuO /80

Cross multiply

Mass of CuO = 0.25 × 80

Mass of CuO = 20 g

Therefore, 20 g of copper (II) oxide, CuO is needed for the reaction.

Answer:

pOH = -log[OH – ]

pH + pOH = 14

Explanation:

I did not understand the question but hope this help!

The pH of a solution is 8.7 and pOH is 5.3

The sum of pH and pOH is 14.

pH + pOH = 14                  

If pH of a solution is 8.7 then pOH is calculated as,

8.7 + pOH = 14

pOH = 14 - 8.7

pOH = 5.3
