A seedling is planted in soil that does not have any clay. What will most likely happen to the plant?
Answer:
Explanation:
Under good conditions the seedling can thrive in soil that does not have any clay as long as it gets the proper nutrients and right amount of sunlight/water that it needs. Clay in soil can provide the nutrients necessary for seedlings to thrive but can also cause many negatives. One such con of using clay is that it does not absorbe water very well, this ultimately causes the soil to become waterlogged and drowns the plants as no oxygen can pass through. This would ultimately kill the plants.

Which of these compounds has the largest percentage by mass of nitrogen? NO N2O NO2 N2O3
The largest mass percentage of nitrogen in NO. Therefore, option (A) is correct.
What is the mass percentage?The percentage by mass of an element in a chemical compound can be described as the number of parts by mass of the element contained in 100 parts by mass of a chemical compound.
The mass percentage of an element can be determined in two steps:
First, calculate the molar mass of the compound and then the percentage of each element by dividing the total mass of the element present in the compound by the molecular mass of the compound multiplied by 100.
Given, the molecular formula of the compound is NO.
The molecular mass of the NO = 30 g/mol
The mass percentage of the Nitrogen = (14/30) × 100 = 46.67 %
the molecular formula of the compound is NO₂.
The molecular mass of the NO = 46 g/mol
The mass percentage of the Nitrogen = (14/46) × 100 = 30.4 %
the molecular formula of the compound is N₂O.
The molecular mass of the NO = 44 g/mol
The mass percentage of the Nitrogen = (14/44) × 100 = 31.81 %
the molecular formula of the compound is N₂O₃.
The molecular mass of the NO = 76 g/mol
The mass percentage of the Nitrogen = (28/76) × 100 = 36.84 %

Question 16
A hockey puck is hit with a large force. The puck moves at a high speed as it slides over the ice.
What happens according to Newton’s first law of motion?
A) The puck does not lose any speed because ice is a very slippery surface.
B) The puck gradually slows down because mass makes objects slow down.
C) The puck gradually slows down because friction would be acting on it.
D) The puck does not lose any speed because once an object starts moving, the force of friction would no longer apply to it.
Answer:
C) The puck gradually slows down because friction would be acting on it.
Explanation:
It would be C because the puck would be scraping the ice and when it's scraping it slowly losses its speed because the ground is pushing it lightly

How can changing the reaction conditions influence the yield of a chemical reaction?
please explain in detail
Answer:
I found this on the web hope this helps.
Explanation:
Le Châtelier's Principle states that a change in pressure, temperature, or concentration will push the equilibrium to one side of the chemical equation. So, if you manipulate the conditions to favor the product side, you increase the yield and vice versa.

determine the volume in liters of metal sample weighting 352.2g and has a density of 7.10gmL.
Answer:
V = 0.0496 L
Explanation:
Given that,
The mass of a sample, m = 352.2 g
The density pf sample, d = 7.10 g/mL
We need to find the volume of the sample. We know that the density of an object is given by :
[tex]d=\dfrac{m}{V}\\\\V=\dfrac{m}{d}\\\\V=\dfrac{352.2}{7.1}\\\\V=49.6\ mL[/tex]
or
V = 0.0496 L
So, the volume of the sample is 0.0496 L.

What is the vapor pressure of propanone
at 50°C?
Answer: If we work it out with direct proportions, the vapor pressure of propanone is 56 degrees Celsius. The atmospheric pressure is about 101.
Explanation: hope this helps.
The vapor pressure of propanone at 50°C is :
- 78° vapor pressure
PropanoneWhen the vapor pressure is specifically work through the extents to a temperature rate it response is intensely subordinate on their possess a mass nature.
The vapor weight of propanone is calculated and shape in degree Celsius in rate.
The rate of vapor when it is calculated by 50°C with propanone its at long last gives us a 78° vapor pressure.

When measuring the brightness of a star, what is a limitation of using apparent magnitude rather than absolute brightness?
Apparent magnitude does not use the star's color or temperature.
Apparent magnitude is only theoretical, thus its value cannot be directly measured with equipment.
Apparent magnitude does not take into account the fact that not all stars are the same distance from Earth.
Apparent magnitude is only on a comparative scale that determines how bright a star looks from a theoretical distance of 32 light-years from Earth.
Answer: Answer:
Explanation:
Apparent magnitude does not take into account the fact that not all stars are the same distance from Earth.
Apparent magnitude is only on a comparative scale that determines how bright a star looks from a theoretical distance of 32 light-years from Earth. Therefore, the correct option is option D.

Solid potassium chloride is obtained by the reaction of solid potassium and chlorine gas.
Write a balanced chemical equation for this reaction.
Answer:
2 K(s) + Cl₂ (g) --> 2 KCl(s)
Explanation:
Potassium will just be K
Chlorine gas is part of BrIClHOF, which are diatomic gasses. So Cl₂
Looking at the periodic table potassium K has an ion charge of +1 and chlorine Cl has an ion charge of -1, so in a balanced compound they will be written as KCl
Balancing the amounts of each will lead to 2 K(s) + Cl₂ (g) --> 2 KCl(s)

If 80mg of a radioactive element decays to 10mg in 30 days, what is the elements
half life in minutes?
Answer: 10 minutes
Explanation:
ln(No/N) = kt
No = 80 mg
N = 10 mg
t = 30 min
solve for k, then
k = 0.693/t1/2
Substitute k from above and solve for t1/2
10 min is correct.

Example 1 How much water (in grams) is produced when 65.2 grams of Calcium carbonate react with phosphoric acid to form calcium phosphate, water, and carbon dioxide?
Answer:
11.75 g H2O
Explanation:
3CaCO3 + 2H3PO4 --> Ca3(PO4)2 + 3H2O + 3CO2
MM H2O = 18.02 g/mol
MM CaCO3 = 100 g/mol
? g H2O = mass CaCO3 x (1 mol CaCO3/MM CaCO3) x (3 moles H2O/3 moles CaCO3) x (MM H2O / 1 mol H2O) = (65.2/100) x 18.02 = 11.75 g H2O
