Marianne designs an experiment involving electrically charged objects. She wants to know which objects will be attracted to a ne

gatively charged balloon. Identify the test variable, the outcome variable, and the control variable for this experiment.
What is the outcome variable in Marianne's experiment?

(You don't need to include the control variable or test variable, you just need to write the outcome variable in her experiment.)

Answer:

OUTCOME VARIABLE: Attraction to negatively charged balloon

Explanation:

In an experiment, two major variables must be included viz: the independent variable and the dependent variable. The independent variable also referred to as the test variable is the variable that is being changed in the experiment while the dependent or outcome variable is the variable that responds to the changes made to the independent variable. The outcome variable is the variable that is measured in an experiment.

In this experiment involving Marianne wanting to know which objects will be attracted to a negatively charged balloon. The type of objects are the independent variable while the ATTRACTION is the outcome or dependent variable as it is dependent on the type of object used.

Enough of a monoprotic acid is dissolved in water to produce a 0.0121 M solution. The pH of the resulting solution is 6.49. Calc
Hitman42 [59]
Calculate the H positive from the pH equation: pH equals -log (H positive). This would be 10 to the -6.49. Let's call the acid HA. To calculate Ka in this equation, Ka equals H positive times A- over HA. HA is going to be the 0 0121. So, Ka=(10^-6.49)^2/0.0121. This equals 1.05*10^-13/0.0121. Ka then equals 8.65*10^-12.

4. How many grams of ammonium carbonate are needed to decompose in order to produce
Thepotemich [5.8K]

Answer:

14.23g of (NH4)2CO3

Explanation:

We'll begin by writing the balanced equation for the reaction.

(NH4)2CO3 –> (NH4)2O + CO2

Next,, we shall determine the mass of (NH4)2CO3 that decomposed and the mass of CO2 produced from the balanced equation. This is illustrated below:

Molar mass of (NH4)2CO3 = 2[14+(4x1)] + 12 + (16x3)

= 2[14 +4] + 12 + 48

= 2[18] + 60 = 96g/mol

Mass of (NH4)2CO3 from the balanced equation = 1 x 96 = 96g

Molar mass of CO2 = 12 + (2x16) = 44g/mol

Mass of CO2 from the balanced equation = 1 x 44 = 44g.

Summary:

From the balanced equation above,

96g of (NH4)2CO3 decomposed to produce 44g of CO2.

Finally, we can determine the mass of (NH4)2CO3 that decomposed to produce 6.52g of CO2 as follow:

From the balanced equation above,

96g of (NH4)2CO3 decomposed to produce 44g of CO2.

Therefore, Xg of (NH4)2CO3 will decompose to produce 6.52g of CO2 i.e

Xg of (NH4)2CO3 = (96 x 6.52)/44

Xg of (NH4)2CO3 = 14.23g

Therefore, 14.23g of (NH4)2CO3 is needed to produce 6.52g of CO2.
