Which products would form if chlorine gas was bubbled through a solution of sodium bromide?

1 answer:

8 0

A displacement reaction will occur from the system given above. The chlorine molecules will displace the bromide ions in the solution of sodium bromide. The reaction will yield to sodium chloride and bromine. The reaction will be:

2NaBr + Cl2 = 2NaCl + Br2

A cube with a mass of 250.0 g has sides measuring 5.00 cm each. What is the density of this cube in grams per cubic centimeter?

stiks02 [169]

The density of the cube in grams per cubic centimeter = D = 2 gram / cm³

Explanation:

The Volume Of the Cube is V = a³

Its is given that the cube has sides measuring 5 cm each side.

V = ( 5 )³

= 5cm 5cm 5cm

V = 125 cm³

The Density Formula, Density= Mass / Volume.

Given that this cube has a mass of 250 grams.

to calculate density

D = ρ = m / V

= 250 / 125

= 2

D = 2 gram / cm³

At 25°C, gas in a rigid cylinder with a movable piston has a volume of 145 mL and a pressure of 125 kPa. Then the gas is compres

natta225 [31]

Answer:

(4) 230 kPa

Explanation:

The temperature is constant, so the only variables are pressure and volume.

We can use Boyle’s Law.

$p_{1}V_{1} = p_{2}V_{2}$

Divide both sides of the equation by $V_{2}$ .

$p_{2} = p_{1} \times \frac{V_{1}}{ V_{2}}$

$p_{1} = \text{145 kPa}; V_{1} = \text{125 cm}^{3}}$

$p_{2} = ?; V_{2} = \text{80. cm}^{3}$

$p_{2} = \text{145 kPa} \times \frac{\text{125 cm}^{3}}{\text{80. cm}^{3}} = \textbf{230 kPa}$

The correlation coefficient is a number between zero and 1 and the answer is <u>false</u>

And that is because the correlation coefficient is a number between -1 and one. A positive correlation coefficient means that two variables are positively correlated or move in the same direction. Plus one means perfect like full correlation, zero means there is no correlation whatsoever.

And a negative correlation means that as one variable moves in a positive direction, the other moves in a negative direction, so that is negative correlation, And the correlation of -1 means perfect negative correlation.

<h3>What Is the Correlation Coefficient?</h3>

The correlation coefficient is a statistical measure of the strength of the relationship between the relative movements of two variables. The values range between -1.0 and 1.0. A calculated number greater than 1.0 or less than -1.0 means that there was an error in the correlation measurement.

A correlation of -1.0 shows a perfect negative correlation, while a correlation of 1.0 shows a perfect positive correlation. A correlation of 0.0 shows no linear relationship between the movement of the two variables.
