Answer:

The data from trial 3 are inconsistent with the data from trials 1 and 2.

Explanation:

I say this because if you look at the chart, using none for trials one and two ended with very little growth, same for "a little", but with " a lot" trial three remains inconsistent from trials one and two. For trials one and two, the growth of the plant increases as the amount of fertilizer increases, but with trials 3, it starts off tall, and shrinks in size as the fertilizer increases, which is opposite of trials one and two.

in which of the following is the symbol for the ion and the number of electrons it contains given correctly? *

gregori [183]

Answer:Number of electrons that are present in an atom is determined by the electronic configuration of that atom.

If an ion is carrying a positive charge, it means that the atom has lost electrons and if an ion is carrying a negative charge, it means that the atom has gained electrons.

For the given options:

Option A: The atomic number of hydrogen atom is 1 and the electronic configuration for ion will be:

Thus, this atom does not have any electrons.

Option B: The atomic number of bromine atom is 35 and the electronic configuration for ion will be:

Thus, this atom has 36 electrons.

Option C: The atomic number of aluminium atom is 13 and the electronic configuration for ion will be:

the volume of gas in a container was originally 3.24L, while at standard pressure 1.00 atm. what will the volume be if the press

Simora [160]

Hello!

To solve this problem, we will use the Boyle's Law, which describes how pressure changes when volume changes and vice-versa. The equation for this law is the following one, and we'll clear for V2:

$P1*V1=P2*V2 \\ \\ V2= \frac{P1*V1}{P2}= \frac{3,24 L * 1 atm}{1,20 atm}= 2,7 L$

So, the final volume after increasing the pressure would be 2,7 L. That means that volume decreases when the pressure increases
