Explanation:

I think it is D. Think about it- if a human jumps, they are less than the gravitational force. But, if you are greater than the gravitational force, I think you will go into space.

The air inside a hot-air balloon is heated to 59.00 °C (Tinitial) and then cools to 39.00 °C (Tfinal). By what percentage does t

Mama L [17]

Answer:

6.1%

Explanation:

Assuming pressure inside balloon remains constant during the temperature change.

Therefore, as per Charles' law at constant pressure,

$\frac{V_1}{T_1} =\frac{V_2}{T_2}$

$T_2=39\°\ C=39+273=312\ K$

$T_1=59°\ C=273+59=332\ K$

$V_2=V_1\times \frac{T_2}{T_1} \\=V_1\times\frac{312}{332}\\=0.939V_1$

Percentage change in volume

$\%\ change\ in\ volume=\frac{V_1-0.939V_1}{V_1} \times 100\\=6.1\%$

Change in volume of the balloon is 6.1%

In the reaction 2H2O (l) + 2Cl– (aq) → H2 (g) + Cl2 (g) + 2OH– (aq), how many electrons are transferred?

lora16 [44]

C. 2

2H_2O + <u>2e</u>^(-) → H_2 + 2OH^(-)

2Cl^(-) → Cl_2 + <u>2e</u>^(-)

2H_2O +Cl^(-) + <u>2e</u>^(-) → H_2 + Cl_2 + 2OH^(-) + 2e^(-)

2H_2O +2Cl^(-) → H_2 + Cl_2 + 2OH^(-)

This is a <em>redox reaction</em> in which two chloride ions transfer two electrons to two molecules of water.
