What are the components needed in order for an experiment to be valid? Identify these components in the following experiment: A scientist is testing a new plant food to see if it causes plants to grow faster. The scientist tests two plants with the new plant food, and two plants he grows without plant food.

Answers

He is missing a (real) control. Growing two plants without plant food at all doesn't count; in order to see if the new food is better, he must also grow plants with the original food in order to compare it. 

He does have an independent variable. This is the type of plant food. It's independent because he has direct control over it.

He needs to give plants the same conditions besides food: same water (amount), same light exposure, same temperature, etc.

He needs to choose a quantitative way to measure how much the plants grew, like mass or length.

Which of these would be easily soluble in water?a. salt
b. oil
c. aluminum foil

Answers

A) Salt, because salt can easily dissolve in water. Oil would not dissolve or evaporate in water (think of an oil spill - does that oil dissappear?). Aluminum foil would definitely not dissolve in water, so it is not soluble.

Which element has 32 protons in its nucleus? phosphorus cobalt germanium sulfur

Answers

Answer:

Germanium.

Explanation:

In a neutral atom: the number of protons = the number of electrons.

Atomic number of a neutral atom = number of electrons = number of protons.

  • Phosphorous is an element with atomic number 15 and thus contains 15 electrons and 15 protons.

  • Cobalt is an element with atomic number 27 and thus contains 27 electrons and 27 protons.

  • Germanium is an element with atomic number 32 and thus contains 32 electrons and 32 protons.

  • Sulfur is an element with atomic number 16 and thus contains 16 electrons and 16 protons.

The element that has 32 protons in its nucleus is Germanium.

1. How the Bible came to be?2. Why it must be regarded as Sacred?
3. Why it should be respected?

Answers

Answer: 1. How the Bible came to be?

What is the mass of 3.0 x 10^23 atoms of neon

Answers

The mass of 3.0 x 10^23 atoms of neon would be 10.09 g

According to Avogadro;

1 mole of neon would have 6.022 x 10^23 atoms

3.0 x 10^23 atoms of neon would have:

            3.0 x 10^23/6.022 x 10^23

                                         = 0.5 moles

mass of 0.5 moles neon = mole x molar mass

                                            = 0.5 x 20.18

                                             = 10.09 g

More on Avogadro number can be found here: brainly.com/question/1445383?referrer=searchResults

Answer: The mass of neon for the given number of atoms will be 9.8 g.

Explanation:

We are given:

Number of neon atoms = 3.0* 10^(23)

According to the mole concept:

6.022* 10^(23) number of atoms. are occupied in 1 mole of a substance.

So, 3.0* 10^(23) will be occupied in = (1)/(6.022* 10^(23))* 3.0* 10^(23)=0.49moles

To calculate the number of moles, we use the equation:

\text{Number of moles}=\frac{\text{Given mass}}{\text{Molar mass}}

Moles of Neon = 0.49 moles

Molar mass of neon = 20 g/mol

Putting values in above equation, we get:

0.49mol=\frac{\text{Mass of neon}}{20g/mol}\n\n\text{Mass of neon}=9.8g

Hence, the mass of neon for the given number of atoms will be 0.49g.
