Yes, if it’s a parallel circuit the wires are two different wires so it will light because that bulb isn’t connected to the one that went out

Question 25 of 26

denis-greek [22]

Answer:

Total mass of leaked fluorine in six months= 0.405 kg

Explanation:

From the given,

Leaked mass of freon = 35.12 gm

Molecular mass of freon = $C_{2}H_{2}F_{3}Cl = (2\times 12)+(2\times1)+(3\times19)+(1\times35.5)=118.5g/mol$

Total weeks per month = 4

Fluorine released into the air in total weeks = $6/times4=24$

3 molecules of fluorine is present in the freon $C_{2}H_{2}F_{3}Cl$

${\tex Mass\,leak\,rate\,of\,fluorine}\,= \frac{Mass\,of\,fluorine\,in\,freon}{Molecularmass\,of\,freon}\times leak\,rate$

$\frac{19\times 3}{118.5}\times 35.12=16.8gm/week$

Total mass of fluorine leaked in six months = $24\times16.9=405.6gm= 0.405 kg$

A solution is made by dissolving 4.87 g of potassium nitrate in water to a final volume of 86.4 mL solution. What is the weight/

lara31 [8.8K]

Answer:

A solution is made by dissolving 4.87 g of potassium nitrate in water to a final volume of 86.4 mL solution. The weight/weight % or percent by mass of the solute is :

2.67%

Explanation:

Note : Look at the density of potassium nitrate in water if given in the question.

You are calculating weight /Volume not weight/weight % or percent by mass of the solute

Here the weight/weight % or percent by mass of the solute is asked : So first convert the VOLUME OF SOLUTION into MASS

Density of potassium nitrate in water KNO3 = 2.11 g/mL

$density=\frac{mass}{volume}$

Density = 2.11 g/mL

Volume of solution = 86.4 mL

$2.11=\frac{mass}{86.4}$

$mass = 2.11\times 86.4$

$mass=182.3grams$

Mass of Solute = 4.87 g

Mass of Solution = 183.2 g

w/w% of the solute =

$= \frac{mass\ of\ solute}{mass\ of\ solution}\times 100$

$=\frac{4.87}{183.2}\times 100$

w/w%=2.67%

Why is a Container important to the sustainability of your hydroponic system?

sergij07 [2.7K]

Hydroponics is more than just another way to grow plants–the technology has the potential to change how we engage with food cultivation as a whole! For the first time since humans started tilling the land, modern hydroponics technology frees us from the soil beneath our feet, allowing us to bring food production indoors where we can layer in additional climate and lighting controls. The result is an ability to grow food anytime, anywhere in the world.
