The neutral Fluorine atom has 9 electrons AND 9 protons. So if the F has a -1 charge, then another electron is added so F will now have 10 electrons. so answer C

10, it has gained and electron which increases the charge, as the -1 indicates

A balloon contains 269.7 L of helium at 6.12ºC and 1.00 atm. What is the temperature (in ºC) of the gas if the volume has increa

MatroZZZ [7]

Answer:

T2= 7.3°C

Explanation:

To solve this problem we will use Charles law equation i.e,

V1/T1 = V2/T2

Given data

V1 = 269.7 L

T1 = 6.12 °C

V2= 320.4 L

T2=?

Solution:

Now we will put the values in equation

269.7 L / 6.12°C = 320.4 L / T2

T2= 320.4 L × 6.12°C/ 269.7 L

T2= 1960.85 °C. L /269.7 L

T2= 7.3°C

Solar, wind, and water power are renewable resources and can replace our dependence on fossil fuels. They each have their own dr

Vesna [10]

Solar- the sun is not always shining, for example at night you can't get any energy from the sun
Wind-it's not always windy
Water- there can be drought
Really the main issue of all three of these is that they are not always available
