Answer:
sulfide ion
Explanation:
however, when non-metalic elements gain electrons to form anions the end of their name is change to "-ide".foe example, a flourin atom gains one electronto become a flouride ion(F`) and sulfur gains two electrons to become a sulfide ion(s^2)
Answer:
Take 3 mL of the 5 M NaCl solution, 10 mL of the 10% glucose solution, and add water for a final volume of 100 mL.
Explanation:
- In order to calculate the required volume of the 5 M NaCl solution, we calculated the moles contained in a 100 mL solution that has a concentration of 150 mM:
0.1 L * 0.150 M = 0.015 moles of NaCl
With those moles we can calculated the required volume, using the concentration of the stock solution:
0.015 mol / 5 M = 0.003 L = 3 mL.
- To make a solution that has a 1 % concentration of glucose, from a 10 % glucose solution, is the same as to make it ten times less concentrated. Thus, with a final volume of 100 mL, you would need to take 10 mL of the 10% glucose solution, because 100mL * 10/100 = 10.
So in order to prepare the solution, you would need to take 3 mL of the 5 M NaCl solution, 10 mL of the 10% glucose solution, and add water for a final volume of 100 mL.

Answer : option B) Gravity acting on the edges of plates and friction between the plate and the asthenosphere.
Explanation : The gravitational force acting on the edges of the tectonic plates raise a friction between the plate and the asthenosphere, which results into the motion of the tectonic plates.
Usually, the tectonic plates are found to move because of the intense heat produced from the Earth's core which causes the molten rock in the mantle layer to move and make a motion. It moves in a pattern which is called as convection cell that forms when the warm material rises, and cools, later eventually sink down producing the motion in the tectonic plates.
The answer is A my good sir
