Which option is a valid hypothesis in the correct format? 1. if a cotton plant receives 100mL of water everyday, it will display steady growth.
2. If a cotton plant displays steady growth, it will receive 100 mL of water every day.
3. If cotton plants need a consistent amount of water to grow steadily, then a cotton plant that receives 100 mL water every day will display steady growth.
4. If cotton plants need a consistent amount of water to grow steadily , then a cotton plant that displays steady growth will receive 100 mL of water every day.

4. If cotton plants need a consistent amount of water to grow steadily, then a cotton plant that displays steady growth will receieve 100 mL of water every day.

Explanation:

Hypotheses are written in the format of "If... then...". It should include information on both variables to arrive at a conclusion point.

the reaction mixture contains some ammonia, plus a lot of unreacted nitrogen and hydrogen. the mixture is cooled and compressed, causing the ammonia gas to condense into a liquid. the liquefied ammonia is separated and removed. the unreacted nitrogen and hydrogen are then recycled back into the reactor .

so here we go

atomic mass

239 + 1 = y + 134 + 3 combine like terms

240 = y + 137             subtract 137 from both terms

240 - 137 = y

103 = y

atomic number

94 = z +54 + 0

94 = z + 54               subtract 54 from both sides.

40 = z
