The tail of a comet always points where?
Answers
Hope that helped! =)
Final answer:
The tail of a comet always points away from the Sun.
Explanation:
The tail of a comet always points away from the Sun. This is due to the interaction between the Sun's radiation and the comet's gas and dust particles. As the comet gets closer to the Sun, the solar radiation causes the ice within the comet to vaporize and release gas and dust particles, forming a glowing tail that always faces away from the Sun.

Suppose you use 0.0150 liter of a 2.50 M solution of silver nitrate. Assuming the reaction goes to completion, how much silver sulfide is produced? Use the periodic table.
A. 1.49 g
B. 4.65 g
C. 9.30 g
D. 18.6 g
Answers
Answer:- B. 4.65 g.
Solution:- The given balanced equation is:
It asks to calculate the mass of silver sulfide formed by when 0.0150 liters of 2.50 M of silver nitrate are used.
Moles of silver nitrate are calculated on multiplying it's liters by its molarity and then on multiplying by mol ratio, the moles of silver sulfide are calculated. These moles are multiplied by the molar mass to convert to the grams.
Molar mass of = 2(107.87)+32.06 = 247.8 g per mol
The dimensional set up for the complete problem is:
=
So, the correct choice is B. 4.65 g.
Answer:
that jawn gon be 4.65 g

Explanation:
global warming causing the icebergs to melt which rises water
Final answer:
The average height of Earth's oceans is increasing mainly due to thermal expansion caused by global warming. The warmer the seawater gets, the more it expands, raising the ocean levels.
Explanation:
The studies show that the average height of all Earth's oceans is indeed increasing over time. Amongst the provided options, a possible cause for this is, A. Seawater is expanding as it gets warmer. This concept is referred to as thermal expansion. When water gets warmer, the molecules have more energy and therefore tend to take up more space. This causes the volume of the ocean to increase, leading to a rise in sea levels. The remaining options - Ocean's conveyor belt speeding up, upwellings becoming more frequent and the moon's gravitational pull decreasing - have minimal or no direct impact on the overall rise in ocean levels.
