★ oxygen
★ fluorine
★ chlorine
oxygen
the answer is going to be oxygen. This is because on the periodic table, sulfur and oxygen are in the same group or "family" in the periodic table of elements.
Answer: Liquid state
Explanation:
There are three states of matter named as solid , liquid and gas.
Solids have fixed shape and fixed volume as the molecules are strongly bonded to each other.
Liquids have fixed volume but no fixed shape as the molecules are weakly bonded to each other.
Gases have neither fixed shaped nor fixed volume as the molecules are very weakly bonded to each other.
b. 29.9 L
c. 44.8L
d. 22.4 L
Answer: d. 22.4 L
Explanation:
According to Avogadro's law , 1 mole of every gas occupies 22.4 L of volume at STP.
moles of ammonia=
Given: Hydrogen is the excess reagent and nitrogen is the limiting reagent as it limits the formation of product.
From the given balanced equation:
2 moles of ammonia is produced by 1 mole of nitrogen.
Thus 2 moles of ammonia is produced by 22.4 L of nitrogen at STP as 1 mole of nitrogen occupies 22.4 L at STP.

Answer:
thermal energy, mechanical energy and chemical energy.
Explanation:
Our body goes into catabolism during running. Complex stored food molecules are broken down into simpler molecules that enter the blood stream and provide energy or fuel for running.
Mechanical energy is the sum of the kinetic and potential. During running we move our limbs, set our body in motion and cover a certain distance. Thus we utilize mechanical energy.
Thermal energy is characterized by a change in temperature. When running there is an increasing in body temperature which is manifested as sweat from the body.
