The Earth's systems are all interdependent, which means that A. each system has no influence on the other systems. B. one system can overpower the other systems, causing damage to the Earth. C. each system works by itself to benefit the Earth. D. each system is unique, yet each interacts with the others.

Answers

Answer 1

Answer: The answer to the question is D. each system is unique, yet each interacts with the others. In an interdependent system, each part of the system works in its own way but interacts with the others. When combined together, all the different systems produce individual benefits but interact with one another to produce a huge benefit for the planet Earth.

How many milliliters of 0.183 m hcl would be required to titrate 5.93 g koh?

Answers

Molar mass:
KOH = 56.0 g/mol

Number of moles of KOH :

5.93 / 36.5 => 0.1624 moles

KOH + HCl = KCl + H₂O

1 mole KOH --------------> 1 mole HCl
0.1624 moles KOH ----> ?

moles HCl = 0.1624 x 1 / 1

= 0.1624 moles of HCl

V ( HCl ) = moles / molarity

V(HCl) = 0.1624 / 0.183

V (HCl) = 0.887 L x 1000 = 887 mL

2. 7.5 g of potassium react with water to produce potassium hydroxide and hydrogen gas. Calculate the mass of potassium hydroxide produced. (8 points)

Answers

Answer:

10.7 g of KOH

Explanation:

First of all, we determine the reaction:

2K (s) + 2H₂O(l) → H₂(g) + 2KOH(aq)

We convert the mass of K, to moles → 7.5 g . mol/39.1 g = 0.192 moles

Ratio is 2:2, so the moles I have of K must produce the same moles of KOH. In this case, the produces moles of KOH are 0.192 moles.

We convert the moles to mass, to finish the answer:

0.192 mol . 56.1g /1mol = 10.7 g of KOH

Torque can be calculated by multiplying the force (N) applied at 90∘ to the lever arm at a distance (m) from the pivot point (point of rotation), the compound SI unit for the torque is N⋅m. If the force (at 90∘ to the lever arm) applied is 15 N and it is applied at 2.0 m from the pivot point (point of rotation), what is the torque on the lever?

Answers

If a lever has a constant force applied at 90∘ to the lever arm at a fixed distance from the pivot point (point of rotation), the torque on the lever is given by Torque = force (at 90∘ to lever arm) × distance to pivot pointForce should be perpendicular to the lever arm
Therefore; you would do 15N X 2.0 m = 30 Nm or 30Joules

Final answer:

The torque on the lever, with a 15 N force applied perpendicular at 2.0 m from the pivot point, is 30 N·m.

Explanation:

The torque on a lever is calculated by the formula T = rF sin θ, where T is torque, r is the distance from the pivot point to the point where the force is applied (lever arm), F is the force applied, and θ is the angle between the lever arm and the direction of the force. In this case, the force is applied at 90° to the lever arm, so the sin θ part of the formula is equal to 1. Therefore, the torque can be calculated by multiplying the force by the lever arm distance. With a force of 15 N applied perpendicular to the lever arm at a distance of 2.0 m from the pivot point, the torque on the lever would be 30 N·m (15 N x 2.0 m).

Which of the following is not true of "concentration"?a. It increases when you add more solute to the solvent.
b. It decreases when you add more solute to the solvent.
c. It decreases when you add more solvent to the solution.

Answers

The correct answer is B. The concentration of a solution does not decreases when you add more solute to the solvent. Instead, the concentration increases. Concentration is expressed as the amount of solute per unit of solvent. Therefore, increasing the solute, increases this value and increasing the solvent, decreases this value.

An atom has 5 protons and 7 neutrons. What is its mass number?

Answers

mass number = protons + neutrons
mass number = 5 + 7
mass number = 12

Mass number = No. of protons + No. of neutrons

= 5 + 7

= 12 u.

Thus, the answer is 12 u.

What is a solar system?

A solar system is the gravitational bound system comprising the sun and the objects aligned in the orbit revolving around the sun. The foundation of the solar system is mediated billions of years ago with the huge interstellar cloud collapse.

The planets are present in the orbit bounded by the gravitational force of the sun and revolve around it. Earth is the planet that is said to have only one having the five elements that support life namely. fire, air, water, soil, and space.

The solar system is comprised of 9 planets with the nearest to the sun being mercury, and the farthest being Pluto. Earth is arranged as the third planet from the distance from the sun and is located between Venus and Mars.
