Answer: Option D) covalent bonds between water molecules

In water, hydrogen bonds are best described as covalent bonds between water molecules

Explanation:

The hydrogen bonds between water molecules are covalent bonds because they are formed when oxygen attract the lone electron in hydrogen, thus resulting in the formation of a partially negative charge on the oxygen atom and a partially positive charge on two hydrogen atoms

Thus, the sharing of electrons between oxygen and hydrogen atoms is responsible for the covalent bonds between water molecules

Earth has approximately 600,000,000 meters of coastline. If we assume this entire length of coastline has sandy beaches 60 meter
VashaNatasha [74]

Answer:

7 and 11

Explanation:

The amount of sand on the beaches can be found using this formula:

volume (m3) = length (m) × width (m) × depth (m)

(6 × 108 m) × 60 m × 20 m = 7 × 1011 m3

Therefore, there would be a total of 7 × 1011 cubic meters of sand on the beaches.

worty [1.4K]

Answer:

A device that does work with only one movement and changes the size or direction of a force is a simple machine.

Explanation:

  • For applying force, any used basic mechanical devices are simple machines.
  • Simple machine changes the direction as well as the amplitude of the applied force i.e. we can increase or decrease the magnitude of the force.
  • A simple machine is the most basic mechanism to use the force as we need in big mechanical machines.
  • Some of the examples of simple machines are inclined plane, lever, wedge, wheel and axle, pulley, and screw.

Suggest one reason why cans are not made entirely from tin
Butoxors [25]

Cans aren't entirely made of tin because of rusting. When scratched(which happens quite frequently to cans) the tin is in more danger of rusting. This is why the cans are coated in a layer of tin rather than the whole can is made of it.

HELP ME PLEASE!! If given a graduated cylinder, a beaker with alcohol and a scale, explain the steps to find the mass of 40 mL o
Luda [366]
<h3>Further explanation </h3>

In general, some people equate mass and weight.

Mass is one of the principal quantities, which is related to the matter , whereas weight is a force that leads to the center of the earth (Earth's gravitational force)

Steps that can be taken  to find the mass :

  • 1. Weigh graduated cylinder (empty)
  • 2. Pour the alcohol in the beaker into the graduated cylinder to the level of 40 ml
  • 3. Weigh again graduated cylinder + poured alcohol
  • 4. mass of alcohol 40 ml = mass in 3rd step - mass in the first step
