Answer:
For instance equation C6H5C2H5 + O2 = C6H5OH + CO2 + H2O will not be balanced, but PhC2H5 + O2 = PhOH + CO2 + H2O will; Compound states [like (s) (aq) or (g)] are not required. If you do not know what products are enter reagents only and click 'Balance'. In many cases a complete equation will be suggested.

The process by which a cell takes in a large particle is called
A
endocytosis.
B
diffusion.
C
active transport.
D
exocytosis.
Answer:
A endocytosis
Explanation:
The process by which a cell takes in a large particle is called endocytosis. Therefore, the correct option is option A.
What is endocytosis?Endocytosis is the procedure by which molecules are actively transported into the cell by being engulfed by its membrane. All cells use endocytosis and exocytosis to transport substances that cannot passively cross the membrane. Exocytosis serves the opposite purpose by ejecting molecules from the cell.
The requirement for homeostasis ensures an equal flow all molecules into and out of a cell, like all of the body's systems. This indicates that the number of molecules exocytosis and endocytosis both equal the number of molecules into the cell. The two systems work together to maintain a balance between nutrients and waste that is necessary for normal cell growth and function. The process by which a cell takes in a large particle is called endocytosis.
Therefore, the correct option is option A.

10.7g of powdered Al is placed into a container containing 10.7g O2. What is the limiting reactant? How many grams of aluminum oxide can be produced? Calculate the mass of excess reactant that remains after the reaction is complete
Limiting reactant : Al
Al2O3 produced = 18.36 g
mass O2 remains = 11.904 g
Further explanationGiven
Reaction
4Al + 3O2 —> 2Al2O3
10.7 g O2
Required
Limiting reactant
mass Al2O3
Mass of excess reactant remains
Solution
mol Al : 10.7 : 27 = 0.396
mol O2 = 10.7 : 32 = 0.334
1. limiting reactant
mol : coefficient of Al : O2 = 0.396/4 : 0.334/3 = 0.099 : 0.111
Al as a limitng reactant(smaller ratio)
2. mass Al2O3
mol Al2O3 based on Al : 2/4 x 0.396 = 0.18
mass Al2O3(MW=102 g/mol) = 0.18 x 102 = 18.36 g
3. mass O2 remains
mol O2 reacted : 3/4 x 0.396 = 0.297
mol O2 remains = 0.669 - 0.297 =0.372
mass O2 remains = 0.372 x 32 = 11.904 g
calculating kinetic energy 1200kg car moving at 10
Answer:
60000J
Explanation:
Given parameters:
Mass of car = 1200kg
Speed = 10m/s
Unknown:
Kinetic energy = ?
Solution:
The kinetic energy is given as:
Kinetic energy = [tex]\frac{1}{2}[/tex] m v²
Now insert the parameters and solve;
m is the mass
v is the velocity
Kinetic energy = [tex]\frac{1}{2}[/tex] x 1200 x 10² = 60000J

A piece of nickel at 25 °C is dropped into a glass of water at 25 °C. Which statement is correct?
Heat will flow from the nickel to the water in the glass.
Heat will flow from the water in the glass to the nickel.
There will be no transfer of heat from the nickel to the water in the glass.
The final temperature of water and nickel will be 0 °C.
Answer:
The temperature of the water in both beakers will decrease
Explanation:
Answer:
I believe it's C. "There will be no transfer of heat from the nickel to the water in the glass."
Explanation:
there won't be any transfer of heat from the nickel to the water in the glass because both the nickel and the glass of water are at the same temperature.
