what will happen to water in a cup if the cup is placed inside a sealed bag and left in a warm area ?

Answers

The water will stay there nothing happens to the water in the bag.

The water may begin to evaporate and you might see condensation on the inside of the bag

Which describes the polarity in a water molecule?

Answers

Answer:

The oxygen atom in a water molecule is strongly electronegative. The atoms of the water molecule are held together by covalent bonds. water has nonpolar bonds, but it has a bent shape and is therefore polar.

How many atoms of calcium are in a unit of calcium phosphate whose formula is Ca3(PO4)2?A) one C) three

B) two D) four

Answers

The correct answer is answer choice C, three. In the formula Ca3 (P O4)2, there are 3 atoms of calcium (Ca), 2 atoms of phosphorus (P), and 8 atoms of oxygen (O). You can tell this by looking at the subscripts (or numbers, in this case, since you can't type subscripts). The subscript applies to the number directly beside it. Furthermore, if you have parentheses with a number beside it, just distribute. In this problem, we have (P O4)2.

(P O4) 2 Given
P2 O8 Distribute
We now have 2 atoms of phosphorus and 8 atoms of oxygen.

This problem has decided to be nice and just ask for calcium, so we don't have to distribute. All you have to do for this problem is look at the subscript beside Ca, which is 3. Therefore, the correct answer is C.

Answer: c

How are electromagnetic waves affected as the frequency of the waves increases?A) energy and wavelength increase
B) energy and wavelength decrease
C) energy decreases, wavelength increases
D) energy increases, wavelength decreases

Answers

When the frequency of the waves increases, its energy increases, while the wavelength decreases.

• A travelling disturbance, which mediates energy from one place to another is known as a wave.

• The tendency to do work or cause a change is known as the energy.

• Waves can be determined with the help of frequency and wavelength.

• In a given unit of time, the number of complete wavelengths is known as frequency.

• With the increase of the size of wavelengths, its energy and frequencydecreases.

• There are two basic kind of waves, that is, electromagnetic and mechanical waves.

• The waves, which can travel through a medium or a vacuum is known as the electromagnetic waves.

• The waves with long wavelengths comprise less energy than waves with short wavelengths.

Thus, correct answer is option d, that is, energy increases, wavelength decreases.

To know more about:

As the frequency is how many waves pass a fixed point in certain amount of times. This means that the waves get closer together and, therefore, the wavelength decreases. It also means that the wave has more energy.

Answer: D) Energy increases, wavelength decreases
