 formulae for finding is
(Mi)(Vi) = (Mf)(Vf) 
<span>(3.0M)(x) = (500.mL/1000)(1.0M)
</span>convert 500ml to liter

<span>x = (0.5 moles)/(3.0 moles/liter) </span>
<span>x = 0.17 Liters = 1.7 x 10^2 mL HCl</span>

Air pressure is measured in pascals. For a professional American football game, the ball should be inflated to about 90,000 pasc
Tatiana [17]

The variable "air pressure inside the football" in this experiment is quantitative and dependent variable. Hence, option D is correct.

<h3>What is the dependent variable?</h3>

The dependent variable is the variable that is being measured or tested in an experiment.

In the experiment, the scientist filled the footballs with fix quantity of pressure which was then kept for 12 hours. After 12 hours the pressure inside the footballs was again measured. Pressure here is a quantitative variable.

Since the air temperature is an independent variable. The pressure being the dependent variable depends upon the temperature of the air.

Independent variable; The variable which does not depends upon any other variable.

Dependent variable; The variable which depends upon the independent variable or varies with the change independent variable.

Qualitative variables are variables which cannot be expressed in form of numbers. They generally convey the characteristic, category, quality or type.

Whereas Quantitative variables are the variables which can be expressed in the form of numbers. These are the variables which exist along the continuous sequence.

Which sentence correctly explains the process and conditions needed for sleet to form?
laiz [17]

Answer:Sleet only happens under very specific weather conditions. There must be a layer of air near the ground whose temperature is below freezing, where water turns to ice. Above this layer of freezing air must be a layer of warmer air. As snow falls through the warm air, it melts or partially melts into raindrops.
