Answer:
You didn't give any options/statements, so I'm just going to give you context on what catalysts does. Catalysts decrease the activation energy needed, allowing more particles for successful reactions.
I know my colleague tried doing an experiment by using hydrogen peroxide as a catalyst and seeing how rates of reactions were affected. It ended up with a stain on our chemistry lab and him re-doing his entire lab.

The formula for the wavelength of a massive particle is
λ = h/p
where
λ = wavelength
h = Plank constant (6.626070040Ă—10^â’34 J*s)
p = momentum (mass times velocity)
So let's solve for momentum and from there get the mass
λ = h/p
λp = h
p = h/λ
Substitute known values and solve
p = 6.626070040Ă—10^â’34 J*s/3.45Ă—10^-34 m
p = 1.92 J*s/m
Since momentum is the product of mass and velocity, we have
p = M * V
p/V = M
So substitute again, and solve.
p/V = M
1.92 J*s/m / 6.55 m/s = M
1.92 kg*m/s / 6.55 m/s = M
1.92 kg*m/s / 6.55 m/s = M
0.293 kg = M
So the mass is 293 grams</span>
Answer:
The volume on the tank is 6, 20 L
Explanation:
We use the formula PV=nRT. We convert the units of pressure in kPa into atm and temperature in Celsius into Kelvin:
0°C=273K
101,325kPa---1 atm
275kPa --------x=(275kPax 1 atm)/101,325kPa= 2,71 atm
PV=nRT --> V=nRT/P
V= 0,750 mol x 0,082 l atm /K mol x 273 K/ 2, 71 atm= <em>6, 20 L</em>
Answer:
Glucose
Explanation:
Glucose molecule is the primary source of energy for most organisms where processes such as glycolysis starts and cellular respiration follows. Bodies of organisms can get energy from carbohydrates, proteins and fats with carbohydrates being the main component for energy where they are converted to glucose which is a form of sugar that reacts to affect blood sugar levels within an hour or two hours after eating.
The second answer option, table salt (NaCl) is incorrect because sodium added in food is vital for functioning of nerves and muscles. Additionally, it helps in fluid regulation and control of blood pressure/volume in the body.
The third answer , hydrochloric acid is not correct because presence of hydrochloric acid in the body helps in breaking down, digestion and absorption of nutrients.
The correct answer choices are : A and D.
