Astudent will measure and record the growth of two flowering plants every day for 28 days. plant a will be watered and fertilized, plant b will only be watered. the student predicts fertilizer added to the soil leads to taller flowering plants. scientific conclusions are based on scientific evidence, what evidence would support the student’s prediction? a) plant a and plant b both die b) plant a grows taller than plant b c) plant b grows taller than plant a d) plant a and plant b grow to the same height

The correct answer will be option-B

Explanation:

In the given question, the experiment was performed to test "if adding the fertilizer will increase the growth of plants" in terms of height and measured the height of the plants.

The experimental group (plant A) was provided with the water and fertilizer whereas the control group (plant B) was provided only water and the height of the plant was recorded which showed that experimental group showed more height.

This can be explained as the fertilizer adds the nutrients to the soil which the plants lack and since the plants get enough amount of fertilizer. Thus, Plant A grows taller than plant  B.

1.consider the following balanced equation and answer parts a through. show calculations for each part.  

3 ag(s) + 4 hno3(aq) → 3 agno3(aq) + no(g) + 2 h2o(l)  

a. calculate the number of moles of agno3 produced by the reaction of 3 moles of ag with excess hno3. if the number to the left of the compound represents the number of moles of the compound which are present, then 3 moles of ag react with 4 moles hno3 to produce 3 moles agno3 (aq).

so the answer to a would be 3 moles.

b. calculate the number of moles of agno3 produced by the reaction of 108 grams of ag with excess hno3.  

i'm not sure how to plug in the grams of silver into an equation using moles to find how many moles are produced.

c. calculate the number of grams of agno3 produced by the reaction of 108 grams of ag with excess hno3  

d. calculate the number of moles of no produced as a byproduct of the reaction of 108 grams of ag with excess hno3.  

e. calculate the number of grams of no produced as a byproduct starting with 108 grams of ag and excess hno3.  

explanation:

they are made of gases.

they have a spherical shape.

they make energy through fusion.
