Vera_Pavlovna [14]

First part:

2 atoms of Na

6 atoms of N

Second part:

2 atoms of N

2 atoms of Na

Why?

We are given the chemical reaction, so, we can extract the number of atoms for both reactants and products.

We are given the chemical equation:

$2NaN_{3}=3N_{2}+2Na$

We can rewrite it as follow:

$2(NaN_{3})=3N_{2}+2Na$

From the reactants, we have:

$2(NaN_{3})$

$2Na=2atoms\\2N_{3}=2*3=6atoms$

From the products we have:

$3N_{2}+2Na$

$3N_{2}=3*2=6atoms$

$2Na=2atoms$

Hence, we have that:

There are 6 atoms of N in the reactants and 6 atoms of N in the products.

and

There are 2 atoms of Na in the reactants and 2 atoms of Na in the products since we have a balanced equation.

Have a nice day!

Question 2 (0 points)

bazaltina [42]

Answer:

The probability of spinning red with the spinner or rolling an odd number with the die is $\dfrac{1}{8}$

Explanation:

Given that,

Total color in spinner = 4

Let the area of four parts is equal in the spinner.

We need to calculate the probability of spinning red

Using formula of probability

$P(A) = \dfrac{Number\ of\ red\ color\ outcome}{Total\ number\ of\ colors\ in\ the\ spinner}$

Put the value into the formula

$P(A)=\dfrac{1}{4}$

We need to calculate the probability of odd number of the die

Using formula of probability

$P(B) = \dfrac{Number\ of\ odd\ digits\ outcome}{Total\ number\ of\ digits\ in\ the\ die}$

Put the value into the formula

$P(B)=\dfrac{3}{6}$

$P(B)=\dfrac{1}{2}$

We need to calculate the probability of spinning red with the spinner or rolling an odd number with the die

Using formula of probability of two events which is independent

$P(A\ and\ B)=P(A)\times P(B)$

Put the value into the formula

$P(A\ and\ B)=\dfrac{1}{4}\times\dfrac{1}{2}$

$P(A\ and\ B)=\dfrac{1}{8}$

Hence, The probability of spinning red with the spinner or rolling an odd number with the die is $\dfrac{1}{8}$
