Soraya left some soup in the refrigerator. She looked at the soup every day, but she always decided not to eat it. After five days, she started to see mold growing on the surface of the soup. She looked up mold online and found that mold is made of fungal cells. Why didn't Soraya see the mold growing on the soup before the fifth day? Why can she see it now? ​

Answers

Explanation:

In general, the longer that moisture is present, the greater the chance for mold to grow and spread. When mold spores encounter a moist surface, it starts growing within a few hours, spreading into the material while also filling the air with thousands of mold spores.

Fact is, the earth was cooling and warming long before greenhouse gases could have been a factor. The [global warming supporters] have been proved wrong time and time again.

What does it mean to say that a wave is cyclic, or periodic, disturbance?

Answers

Answer:

Wave is a disturbance or energy that propagate through medium from one point to other point

So basically it is a flowing energy that flows into the medium and hence medium particles start oscillating about their mean position to and fro.

This motion of medium particles or this to and fro motion is about their mean position and this will always be cyclic or periodic motion

This means the disturbance or energy continuously flow through the medium such that it will change the position of medium particle and this will be cyclic in order

For an example

y(x,t) = Asin(kx - ωt + φ)

So here above equation of wave is a travelling wave in which displacement of medium particle from its mean position is given by "y"

Now we can see that this disturbance depends upon the sine function and it will repeat its same position after every 2 pi time interval as it is cyclic function for this value

Due to this phenomenon of repetition of its same position we can say that it is disturbance of wave is cyclic.

Use the equation to answer the question.

CH4 + _____Cl2 → CCl4 + _____HCl

Which numbers balance this equation?

Answers

The whole Balanced Reactions Quick Check for Honors Chemistry A is

1) A. The reactants and products have the same number and type of atoms, but the atoms may be recombined.

2) B. It shows how many molecules there are of a particular substance.

3) D. NaOH + HCl → NaCl + H2O

4) A. Atoms always remain intact during chemical reactions.

5) D. 4, 4

The balanced chemical equation is:

CH₄ + 4Cl₂ —> CCl₄ + 4HCl

The numbers that balanced the equation are: 4, 4

To know the number that balanced the equation, we shall simply balance the equation.

CH₄ + Cl₂ —> CCl₄ + HCl

There are 4 atoms of H on the left side and 1 atom on the right side. It can be balance by writing 4 before HCl as shown below:

CH₄ + Cl₂ —> CCl₄ + 4HCl

There are 2 atoms of Cl on the left side and a total of 8 atoms on the right side. It can be balance by writing 4 before Cl₂ as shown below:

CH₄ + 4Cl₂ —> CCl₄ + 4HCl

Now, the equation is balanced

The numbers that balanced the equation are 4,4

Answer:

An atom is the smallest partical in the universe that makes up everything you see around you. Every chemical element is also made up of atoms. Since atoms are what give each element their defining characteristics, each element can be composed of multiple atoms but you must have all of the same type of atoms combined in order for it to be considered an element. For example the element gold can only contain gold atoms. If you mix the atoms of one element with the atoms of another your substance has then been changed from an element to a compound.
