Answer:
Phosphorus, chlorine and selenium.
Explanation:
If you look at a periodic table, you will notice that phosphorus, chlorine and selenium are all in groups 15-17. Elements in these groups are more likely to gain electrons then they are to lose them, thus making them more likely to form an anion.
This is because they want to fill their outer valence shell of electrons so that they can have a full octet and for groups 15-17 it’s easier to gain 1-3 electrons then it is to loose 5-7 electrons.
Answer:
The new volume is 7.27 L
Explanation:
Step 1: Data given
The initial volume of the balloon = 7.0 L
The pressure = 765 mmHg = 765/760 atm = 1.00658 atm
The pressure drops to 737 mmHg = 737/ 760 atm = 0.969737
The temperature remains constant
Step 2: Calculate the new volume
P1*V1 = P2*V2
⇒with P1 = the initial pressure in the balloon = 765 mmHg
⇒with V1 = the initial volume = 7.0L
⇒with P2 = the decreased pressure = 737 mmHg
⇒with V2 = the new volume = TO BE DETERMINED
765 mmHg * 7.0 L = 737 mmHG * V2
V2 = (765 mmHG * 7.0 L) / 737 mmHG
V2 = 7.27 L
The new volume is 7.27 L
Answer:
Urinary system here is best described as:
D. regulates fluid balance and eliminates waste.
Explanation:
- The major functional organ i.e.our kidney is responsible and is the major functional organ that carry out the urine out of the body.
- The functional unit of kidney is nephron.
- The functional system of urinary system is also been named as Renal system which works in the order of producuing, storing and eliminating the urine out of body.
- Kidney functions for the excretion of waste in form of urine from the body.
- It is stated that there are about 1,000,000 filtering units are called nephrons.
- It get passed within every 45 minutes.
Answer:
45.0 L is the volume of gas will the balloon contain at 1.35 atm and 253 K.
Explanation:
Using Ideal gas equation for same mole of gas as
Given ,
V₁ = 25.0 L
V₂ = ?
P₁ = 2575 mm Hg
Also, P (atm) = P (mm Hg) / 760
P₁ = 2575 / 760 atm = 3.39 atm
P₂ = 1.35 atm
T₁ = 353 K
T₂ = 253 K
Using above equation as:
Solving for V₂ , we get:
<u>V₂ = 45.0 L</u>
45.0 L is the volume of gas will the balloon contain at 1.35 atm and 253 K.
Answer: 215
Explanation:
Volume doesn’t add up into ounces that’s mass only
